Hardware Limitations:

  • The CPU and motherboard have specified limits for memory speeds, especially with multiple DIMMs.

4. Initial Troubleshooting Steps

To address the challenges, I began with foundational troubleshooting steps that often resolve common issues.

4.1 Updating the BIOS

Purpose:

Updating the BIOS is the foundational step in resolving compatibility issues, especially with new hardware technologies like DDR5 RAM. The BIOS (Basic Input/Output System) acts as the bridge between the system’s hardware and software, initializing components during the boot process.

Modern BIOS updates often include microcode revisions that improve support for new CPUs, memory modules, and overclocking features. In the context of overclocking and memory configuration, an updated BIOS can provide enhanced memory compatibility lists (QVL), better memory timing handling, and improved stability at higher frequencies.

This is crucial when working with mixed RAM modules and attempting to push the system beyond standard specifications.

Theory Behind It:

  • BIOS Role in Hardware Initialization:
    • The BIOS initializes hardware components during the boot process.
    • An outdated BIOS might not recognize new RAM modules correctly or handle mixed configurations efficiently.
  • Manufacturer Updates:
    • Manufacturers release BIOS updates to address known issues, improve stability, and support new hardware.

Steps:

  1. Identify Current BIOS Version:
    • Restarted the system and pressed Delete to enter the BIOS setup.
    • Noted the BIOS version displayed on the main screen.
  2. Download Latest BIOS:
    • Visited MSI’s official website.
    • Navigated to the support page for the MSI B650-S motherboard.
    • Downloaded the latest BIOS file.
  3. Prepare BIOS Update:
    • Formatted a USB flash drive to FAT32.
    • Copied the BIOS file to the root directory of the USB drive.
  4. Flash the BIOS:
    • Entered the BIOS setup and accessed the M-FLASH utility.
    • Selected the BIOS file from the USB drive.
    • Followed on-screen instructions to complete the update.
    • Ensured the system remained powered on during the process.

Outcome:

  • Successfully updated the BIOS.
  • Verified the new version upon reboot.

Insights:

Manufacturers continually refine the BIOS to address bugs, security vulnerabilities, and to enhance hardware support. With DDR5 being relatively new, early BIOS versions may lack the optimizations necessary for stable operation at advertised speeds, particularly when mixing different RAM modules.

Updating the BIOS can unlock advanced settings, such as refined voltage controls and memory timing adjustments, which are essential for fine-tuning overclocking parameters. Additionally, updated BIOS versions often improve the memory training algorithm—a process during boot-up where the system determines optimal settings for memory operation.

This is particularly important for achieving stability with high-speed RAM and complex configurations involving multiple DIMMs.

4.2 Correct RAM Installation

Purpose:

Proper physical installation of RAM modules ensures they operate in the correct mode (e.g., dual-channel), maximizing performance and reducing potential compatibility issues. Correct installation allows the memory controller to function efficiently, reducing latency and maximizing throughput. This step is crucial when dealing with mixed RAM modules and when attempting to overclock, as it minimizes potential mismatches in timings and electrical properties between channels, enhancing stability.

Theory Behind It:

Dual-Channel Architecture:

  • Dual-Channel Architecture: Memory controllers can access two memory modules simultaneously, doubling the data throughput. This requires modules to be installed in specific slots to leverage dual-channel mode.
  • Matching Modules: Installing matching RAM modules in the same channel can improve stability by reducing timing discrepancies and signal integrity issues. This is particularly important for overclocking, where synchronized signals across all modules are essential.

Steps:

Consult the Motherboard Manual:

  • Checked the recommended DIMM slot configurations for dual-channel operation.

Install RAM Modules:

  • Channel A (DIMM_A2 and DIMM_A1): Installed both Crucial modules.
  • Channel B (DIMM_B2 and DIMM_B1): Installed both Corsair modules.

Ensure Proper Seating:

  • Carefully inserted each module until the retaining clips clicked into place.
  • Avoided applying excessive force.

Mistake and Correction:

  • Initial Mistake: Mixed modules across channels, leading to potential instability.
  • Correction: Rearranged modules to have matching pairs in each channel.

Insights:

Motherboards are designed with specific slot configurations to optimize memory performance. Typically, slots are color-coded or labeled (e.g., DIMM_A1, DIMM_A2, DIMM_B1, DIMM_B2) to guide proper installation. By placing matching RAM modules in the same channel, we reduce the likelihood of timing discrepancies and signal integrity issues. This is crucial for overclocking since the memory controller must synchronize signals across all modules. Incorrect installation can lead to single-channel operation, limiting bandwidth and potentially causing instability due to uneven load on the memory controller. Ensuring correct placement also helps in leveraging technologies like AMD’s Infinity Fabric, which benefits from balanced memory configurations for optimal CPU-to-memory communication.

Note: I tested all RAM configuration and when Only Using 2 DIMMs the RAM must be in separate channels. (A2, B2) However in my configuration it was optimal to mix the Brand of RAM within these channels, meaning the brand was specific tot he channel, Crucial in A and Corsair in B. If placed the other way around with just two DIMMS at 32GB, one of the overclocking profiles would disappear in the bios and the speeds reduced to safe JEDSEC speeds.

5. Manual BIOS Configuration

With the basics addressed, I moved on to manually configuring BIOS settings to achieve the desired memory speed and stability.

5.1 Resetting BIOS to Default Settings

Purpose:

Resetting the BIOS to default settings provides a clean baseline configuration, eliminating any erroneous or conflicting settings that could hinder system performance or stability. This is a crucial step before applying new overclocking parameters or troubleshooting hardware issues, as it ensures that no residual configurations interfere with the new settings, especially when dealing with complex memory timings and voltages.

Theory Behind It:

Eliminating Conflicting Settings:

  • Previous adjustments may cause unforeseen conflicts.
  • Default settings are the baseline tested by the manufacturer.

Steps:

Enter BIOS Setup:

  • Restarted the computer and pressed Delete during boot.

Load Optimized Defaults:

  • Navigated to Save & Exit > Load Optimized Defaults.
  • Confirmed the action.

Save and Exit:

  • Saved changes and rebooted.

Insights:

Over time, BIOS settings may accumulate changes from previous tweaks, updates, or automatic adjustments that could conflict with current hardware configurations. A factory reset clears these residual settings, which is particularly important when introducing new RAM modules or mixing different brands and specifications.

Starting from default settings allows us to methodically apply overclocking adjustments, ensuring that each change is deliberate and its effects can be accurately assessed. This systematic approach is vital in overclocking, where stability hinges on precise timing and voltage configurations.

5.2 Disabling Automatic Overclocking Profiles

Purpose:

Disabling automatic overclocking profiles like XMP (Extreme Memory Profile) or AMD’s EXPO ensures that the system doesn’t apply aggressive memory settings that may not be compatible with mixed RAM modules. This step allows for manual configuration of memory timings and frequencies, providing greater control over the overclocking process and enhancing the potential for achieving a stable configuration tailored to the specific RAM combinations.

Theory Behind It:

EXPO/XMP Profiles:

  • Predefined settings stored on the RAM modules for easy overclocking.
  • Designed for matched modules and may not suit mixed configurations.

Manual Control:

  • Provides the ability to tailor settings to the specific combination of RAM.

Steps:

  1. Enter BIOS Setup.
  2. Navigate to Overclocking Settings: Found under OC or Overclocking.
  3. Disable EXPO Profile:
    Located A-XMP or EXPO setting.
    Set to Disabled.

Mistake and Correction:

Initial Mistake: Left EXPO enabled, causing instability.

Correction: Disabled EXPO to prevent automatic, potentially incompatible adjustments.

Insights:

Automatic overclocking profiles are designed for ease of use, applying predefined settings optimized for matched memory kits. However, when mixing RAM modules with different specifications, these profiles may attempt to set timings and voltages that one or more modules can’t support, leading to system instability or failure to boot.

By disabling these profiles, we prevent the BIOS from applying potentially incompatible settings. Manual configuration becomes essential, allowing us to set conservative timings and frequencies that accommodate the limitations of all installed modules, which is a fundamental practice in safe and effective overclocking.

5.3 Manually Setting Memory Frequency and Timings

Purpose:

Manually configuring memory frequency and timings allows for precise adjustment of the RAM’s operational parameters, aligning them with the capabilities of mixed modules. This approach is essential in overclocking, as it enables the user to balance performance and stability, particularly when default settings or automatic profiles fail to achieve a stable system. Customizing these settings can help overcome the limitations imposed by conservative JEDEC standards, maximizing the potential of high-speed DDR5 memory.

Theory Behind It:

Understanding Timings:

  • Memory timings determine how fast the RAM can respond to commands.
  • Lower timings are faster but may be less stable with mixed modules.

Starting Conservatively:

  • Beginning with lower frequencies increases the likelihood of stability.
  • Incremental increases help identify the maximum stable settings.

Steps:

  1. Set Memory Frequency:
    • Under OC settings, set DRAM Frequency to DDR5-3600MHz.
  2. Configure Primary Timings:
    • Navigated to Advanced DRAM Configuration.
    • Set primary timings to the slower module’s specifications:
      • tCL: 30
      • tRCD: 30
      • tRP: 30
      • tRAS: 58
  3. Adjust Secondary Timings (Optional):
    • Left on Auto initially to simplify the process.
  4. Save and Exit:
    • Saved changes and rebooted.

Testing and Adjustment:

  • Booted successfully at 3600 MT/s.
  • Incrementally increased frequency and tested for stability.
  • Encountered instability beyond 4000 MT/s.

Insights:

Memory frequency and timings directly impact system performance and stability. Higher frequencies offer increased bandwidth but may require looser (higher) timings to remain stable, especially with multiple or mixed DIMMs. By manually adjusting these parameters, we can set the memory to operate at frequencies that both sets of modules can handle, using timings that prevent data corruption or transmission errors.

Understanding the relationship between timings (like CAS latency, tCL; RAS to CAS delay, tRCD; Row Precharge time, tRP; and Active to Precharge delay, tRAS) and memory frequency is crucial. Overclocking requires a delicate balance—tightening timings can improve performance but may reduce stability, whereas loosening timings can enhance stability at higher frequencies.

5.4 Adjusting Voltage Settings

Purpose:

Adjusting voltage settings for the DRAM and memory controller (SOC voltage) is critical in overclocking to ensure that the memory modules and the CPU’s memory controller receive adequate power to operate at higher frequencies.

Proper voltage tuning can enhance stability, allowing the system to maintain reliable performance under increased electrical demands imposed by overclocked settings and mixed memory configurations.

Theory Behind It:

Voltage and Stability:

  • Higher frequencies require more power.
  • Adequate voltage ensures signal integrity.

Risks:

  • Excessive voltage can generate more heat and potentially damage components.
  • Must be balanced carefully.

Steps:

  1. Enter BIOS Setup.
  2. Navigate to Voltage Settings:
    • Found under OC > Voltage Settings.
  3. Adjust DRAM Voltage:
    • Increased DRAM Voltage (VDD and VDDQ) from 1.35V to 1.4V.
  4. Save and Exit:
    • Saved changes and rebooted.

Testing:

  • Retested at higher frequencies.
  • Noticed only slight improvements in stability.

Insights:

Voltage plays a significant role in the stability and performance of overclocked memory. Increasing the DRAM voltage can help the RAM modules sustain higher frequencies and tighter timings by compensating for the increased electrical stress. However, excessive voltage can lead to overheating and reduce the lifespan of the components. Similarly, adjusting the SOC voltage, which supplies power to the memory controller within the CPU, can improve the controller’s ability to handle higher memory speeds and multiple DIMMs.

Careful voltage adjustments require an understanding of the hardware’s safe operating limits and involve monitoring temperatures to prevent thermal issues. This precise control over voltage settings is a cornerstone of effective and safe overclocking practices.

6. Advanced BIOS Tweaks

To further enhance stability, I explored more advanced BIOS settings related to the memory controller and signal integrity.

6.1 Adjusting SOC Voltage

Purpose:

Increasing the System-on-Chip (SOC) voltage enhances the stability of the CPU’s integrated memory controller (IMC) when operating under the increased demands of overclocked memory and multiple DIMMs.

This adjustment is crucial for achieving higher memory frequencies and stability, as it ensures that the IMC has sufficient power to manage the data flow between the CPU and RAM, especially when dealing with the complexities of mixed RAM modules.

Theory Behind It:

SOC Voltage Role:

  • Supplies power to the IMC and other integrated components.
  • Increasing SOC Voltage can stabilize the IMC during heavy memory operations.

Caution:

  • Over-voltage can cause overheating or damage.
  • Must monitor temperatures closely.

Steps:

  1. Enter BIOS Setup.
  2. Navigate to Voltage Settings:
    • Located under OC > Voltage Settings.
  3. Adjust SOC Voltage:
    • Increased from 1.1V to 1.15V.
  4. Save and Exit:
    • Saved changes and rebooted.

Monitoring:

  • Used HWMonitor to track SOC temperatures.
  • Ensured they remained within safe operating limits.

Insights:

The SOC voltage directly affects the IMC’s performance. A slight increase in SOC voltage can compensate for the additional electrical load introduced by higher memory speeds and the presence of four memory modules. However, it’s important to adjust this voltage cautiously, as excessive SOC voltage can generate additional heat and potentially damage the CPU.

Balancing the SOC voltage involves understanding the CPU’s specifications and safe voltage thresholds. In overclocking, fine-tuning the SOC voltage can make the difference between an unstable system and one that runs high-speed memory configurations reliably.

6.2 Configuring Advanced DRAM Settings

Purpose:

Tweaking advanced DRAM settings, such as Command Rate, Gear Down Mode, Power Down Mode, and Memory Context Restore, allows for deeper control over memory operations. These settings can improve signal stability and timing accuracy, which are essential when overclocking RAM and running complex memory configurations with mixed modules.

Theory Behind It:

Command Rate (CR):

  • Refers to the delay between the memory controller and RAM module.
  • A setting of 2T provides more stability at the cost of slight performance decrease.

Gear Down Mode (GDM):

  • Simplifies memory command timing.
  • Helps with stability at higher frequencies.

Power Down Mode & Memory Context Restore:

  • Disabling these prevents the RAM from entering low-power states that could disrupt overclocked settings.

Steps:

  1. Command Rate (CR):
    • Set to 2T in Advanced DRAM Configuration.
  2. Gear Down Mode (GDM):
    • Enabled to help with command timing.
  3. Power Down Mode:
    • Disabled to maintain consistent power to the RAM.
  4. Memory Context Restore:
    • Disabled to prevent potential issues during system resume from sleep states.

Insights:

  • Command Rate (CR): Adjusting the Command Rate to 2T increases the time between memory commands, providing the memory controller with additional time to manage data, which can enhance stability, especially with multiple DIMMs.
  • Gear Down Mode (GDM): Enabling GDM simplifies the memory controller’s command encoding, effectively reducing the complexity of signal timing. This can improve stability at higher frequencies but may slightly affect performance due to increased latency.
  • Power Down Mode: Disabling this mode keeps the memory in a constant active state, preventing potential delays and instability that can occur when the memory transitions between power states, which is beneficial during overclocking.
  • Memory Context Restore: Disabling this setting forces the system to retrain the memory configuration on each boot, which can improve stability by ensuring that the optimal settings are applied consistently, though it may slightly increase boot times.

Configuring these advanced settings requires a nuanced understanding of how they affect memory operations. In overclocking, they offer additional levers to pull in the pursuit of achieving higher speeds and stability, particularly in challenging configurations involving mixed RAM modules.

6.3 Understanding RTT Settings

Purpose:

Adjusting RTT (On-Die Termination) settings optimizes the termination resistance of the memory modules, improving signal integrity by minimizing reflections and interference on the data lines. This is crucial for maintaining stability and reliability at higher memory frequencies and when using multiple DIMMs, as it enhances the quality of communication between the memory controller and the RAM modules.

Theory Behind It:

RTT NOM, RTT WR, RTT PARK:

  • Control termination resistances during different memory operation phases.
  • Proper termination reduces signal reflections, enhancing stability.

Steps:

  1. RTT NOM WR (Write Termination):
    • Set to Auto or Disabled.
  2. RTT NOM RD (Read Termination):
    • Set to Auto or Disabled.
  3. RTT PARK:
    • Set to Auto or 240 ohms.

Insights:

RTT settings (RTT NOM, RTT WR, RTT PARK) control how termination resistances are applied during different phases of memory operation:

  • RTT NOM (Nominal): Active during idle periods, helps maintain signal levels.
  • RTT WR (Write): Active during write operations, ensures signal integrity when data is being sent to the memory.
  • RTT PARK: Active during specific command phases, helps with signal termination when the bus is parked.

Optimizing these settings can reduce electrical noise and crosstalk between the memory modules, which is essential when pushing the RAM beyond standard speeds. However, incorrect RTT configurations can lead to increased errors and instability.

Overclockers need to experiment with these settings, often starting with manufacturer recommendations or known stable configurations, to find the optimal balance for their specific hardware setup.

6.4 Adjusting Additional Voltage Settings

Purpose:

Fine-tuning additional voltage settings, such as the CPU Core Voltage and enabling Load-Line Calibration (LLC), ensures that the CPU operates within safe voltage ranges while maintaining stability under overclocked conditions. This is vital not only for protecting the CPU from potential damage due to overvoltage but also for ensuring that voltage fluctuations don’t lead to instability during high-load scenarios, which is particularly important when overclocking both the CPU and memory.

Theory Behind It:

CPU Core Voltage:

  • High voltages increase performance headroom but also generate more heat.
  • Default settings may not be optimal for individual CPUs.

Load-Line Calibration (LLC):

  • Stabilizes voltage supply under varying loads.
  • Prevents voltage drops (vDroop) during high CPU usage.

Steps:

  1. Check CPU Core Voltage:
    • Noticed it was at 1.460V by default, which is high.
  2. Adjust CPU Core Voltage:
    • Manually set to 1.35V in BIOS.
  3. Enable Load-Line Calibration (LLC):
    • Set LLC to Level 3 to help maintain voltage stability.

Monitoring:

  • Used HWMonitor and Ryzen Master to track CPU temperatures and voltages.

Insights:

  • CPU Core Voltage: Running the CPU at a voltage higher than necessary can cause excessive heat and reduce the processor’s lifespan. By manually setting the CPU Core Voltage to an optimal value (e.g., lowering from an excessively high default of 1.460V to 1.35V), we can reduce thermal output while maintaining performance.
  • Load-Line Calibration (LLC): LLC helps stabilize the voltage supplied to the CPU by compensating for voltage droop (vDroop) that occurs under load. Adjusting LLC levels can prevent sudden voltage drops that might cause system instability or crashes during intensive tasks or benchmarking.

Balancing these voltage settings requires careful consideration and monitoring. Overclockers must ensure that the CPU receives enough power to operate reliably under load without exceeding thermal limits. This involves iterative testing and may differ between individual CPUs due to variations in silicon quality (often referred to as the “silicon lottery”).

7.2 Identifying the CPU Memory Speed Limit

Purpose:

Understanding and acknowledging the CPU’s memory speed limitations is crucial in setting realistic overclocking goals and preventing unnecessary stress on the hardware.

Recognizing that the Ryzen 7 8700G has an official memory speed limit when using four DIMMs guides the overclocking process, ensuring efforts are focused within achievable parameters and mitigating the risk of system instability or hardware damage.

Theory Behind It:

Memory Controller Limitations:

The Ryzen 7 8700G’s IMC has a maximum officially supported speed when all DIMM slots are populated.

Impact on Overclocking: Pushing beyond these limits can lead to instability or hardware damage.

Discovery: Confirmed that the maximum supported memory speed with four DIMMs is 5200 MT/s.

Conclusion:

  • Accepted that 5200 MT/s was the realistic ceiling for my configuration.
  • Adjusted expectations accordingly.

Insights:

The integrated memory controller (IMC) within the CPU has design specifications that define the maximum supported memory speeds for different configurations (e.g., number of DIMMs, single vs. dual-rank modules). Exceeding these specifications can:

  • Cause Instability: The IMC may not handle the increased electrical load and signal complexity, leading to crashes, data corruption, or failure to boot.
  • Reduce Performance: Pushing the memory beyond the IMC’s capabilities could result in the system defaulting to lower speeds or relaxed timings, negating any potential gains.
  • Risk Hardware Damage: Excessive voltage or sustained operation outside of design limits can shorten component lifespan.

By identifying the maximum supported speed of 5200 MT/s for the Ryzen 7 8700G with four DIMMs, we can focus on optimizing settings within this boundary. This ensures that overclocking efforts enhance performance without compromising stability or hardware integrity. It also directs attention towards refining timings and voltages to maximize performance at this supported speed.

7.3 Pushing the CPU and iGPU Performance Using Ryzen Master

Final Thoughts:

While the initial goal was to run at 6000 MT/s, achieving a stable 5200 MT/s aligns with the official specifications of the Ryzen 7 8700G when using four DIMMs. The adjusted timings of 44-44-44-84 provided the necessary stability without significantly impacting performance.

Insights on Adjusted Timings

Purpose of Adjusted Timings:

The adjusted primary timings of 44-44-44-84 are looser than the initial target timings. Loosening memory timings can enhance stability, especially when operating at higher frequencies or when the memory controller is under increased load, such as with four DIMMs populated.

Reasoning and Logic Behind Adjusted Memory Timings and Voltages

Adjusted Memory Timings

  • Higher CAS Latency (tCL): Increasing tCL from 36 to 44 gives the memory more time to respond to column access strobe signals. This additional time is crucial when operating at higher frequencies like 5200 MT/s, as it reduces the likelihood of errors and enhances stability. The higher tCL accommodates the increased electrical demands placed on the memory modules during overclocking.
  • Balanced tRCD and tRP: Matching tRCD (RAS to CAS Delay) and tRP (Row Precharge Time) to tCL (all set to 44) simplifies the timing relationships between these critical parameters. Synchronizing these timings ensures consistent delays in accessing memory rows and columns, which can significantly improve stability in complex configurations involving mixed RAM modules and all four DIMM slots populated.
  • Adjusted tRAS: Setting tRAS (Active to Precharge Delay) to 84 bus clocks ensures that each memory row has adequate time to complete its operations before precharging. This alignment with the increased primary timings helps prevent data corruption and enhances overall system reliability at elevated memory speeds.

Impact on Performance

  • Latency vs. Frequency Trade-off: While higher timings indicate increased latency (slower response times), the substantial increase in memory frequency from the default 3600 MT/s to 5200 MT/s results in higher memory bandwidth. In many real-world applications, the benefits of higher bandwidth outweigh the drawbacks of increased latency, leading to overall improved system performance.
  • Real-World Applications: The higher memory frequency benefits tasks that require rapid data transfer between the memory and CPU, such as large file processing, gaming, and multimedia editing. The slight increase in latency is often imperceptible in everyday use, especially when balanced against the substantial gains in bandwidth.

Voltage Considerations

  • DRAM Voltage (VDD & VDDQ): Maintaining the DRAM voltage at 1.1V instead of increasing it to the standard 1.35V reduces thermal stress on the memory modules. Lower voltage levels minimize heat generation, which is beneficial for component longevity and overall system stability. Operating at 1.1V demonstrates that the memory modules can function reliably at a lower voltage when timings and frequencies are appropriately adjusted.
  • SOC Voltage: Setting the SOC voltage to 0.9875V provides sufficient power to the Integrated Memory Controller (IMC) for stable operation at higher memory frequencies. Keeping the SOC voltage below the standard maximum helps in reducing heat output and power consumption, contributing to a cooler and more energy-efficient system.

Balancing Performance and Stability

  • Looser Timings for Stability: The decision to loosen the primary timings to 44-44-44-84 was essential for achieving stability at 5200 MT/s, especially given the challenges of mixing RAM modules and populating all four DIMM slots. This approach balances the memory’s ability to operate at higher speeds with the need for reliable performance.
  • Avoiding Excessive Voltages: By not overvolting the DRAM and SOC, thermal management becomes more manageable. Operating within safe voltage ranges prevents undue stress on components, reducing the risk of overheating and potential hardware failures.
  • Component Longevity: Lower voltages and managed thermal output contribute to the longevity of the memory modules and CPU. This careful voltage management ensures that the overclocked system remains reliable over time without degrading the components prematurely.

Conclusion

By methodically adjusting the memory timings to 44-44-44-84 and carefully managing voltage levels, I achieved a stable overclock of 5200 MT/s on a system that officially supports only up to 3600 MT/s for my configuration. This balance between higher frequency and looser timings, along with optimized voltage settings, provided a significant performance boost while maintaining system stability and component health.

This strategy underscores the importance of understanding the interplay between frequency, timings, and voltage in overclocking. It demonstrates that with precise adjustments and a focus on stability, it’s possible to push hardware beyond its rated specifications without compromising performance or longevity.
