Check RAM and CPU timing, clock speeds, voltage levels, and configuration settings.
Looking for guidance on adjusting your CPU's clock and voltage settings, as well as memory timings. Your current memory timing works well, but you're unsure about the best approach—especially since XMP didn't work for you. For a 1.4V operation, the first five numbers typically range from 0 to 72, depending on your specific chipset and configuration. If you need to push it higher, ensure you start with a conservative setting and consider manual tweaks rather than auto. Let me know if you'd like help planning the initial values.
We require additional details about the system configuration. Please share information such as CPU type, motherboard model, RAM specifications, memory IC used, and other relevant components. Without this data, providing accurate guidance would be extremely challenging.
your cpu runs at 1.255v with a negative of -14 on all cores. the curve optimizer is set to 4.2ghz, and your ram is 2x 8gb crucial ballistix ddr4-3200 cl16. check the recommended voltage range for xmp boosting and see how far you can push it safely.
When performing a manual CPU overclock, the curve optimizer and other PBO adjustments won’t help much. You can either turn off the manual OC and focus on PBO tuning, or proceed with the manual overclock. Personally, I’d skip the manual approach unless you reach 4.4GHz or higher; otherwise, PBO usually gives better overall results. If you boost the voltage to around 1.35V (which is safe for long-term use), and you have adequate cooling, you should achieve 4.4GHz+. This setup is likely Micron 8Gb Rev. E. The challenge with Micron lies in its timing variations—some kits can hit 14-16-16 at 1.4V, while others cap at 16-18-18 at that voltage. However, it excels in clock speed, especially on Ryzen 5000 APUs, often reaching 4800MT/s or more with the right voltage and stable timings.
You’ll need powerful cooling to support such speeds. If you can meet those requirements, you should be able to push beyond 4.4GHz. Regarding memory tuning, Micron’s performance is less predictable compared to other brands. Some kits manage 14-16-16 at 1.4V, while others struggle with higher frequencies. The real strength here is clock speed, which is crucial for those high-end APUs.
For memory overclocking, you might start by setting timings to 22-33-33-66 and gradually increase frequency until crashes appear in memory tests (like Y-Cruncher 2.5B). Then adjust SOC voltage (keep below 1.2V if possible) and VDIMM voltage (max 1.65V, but be cautious above 1.5V). Test one change at a time—start with tCL and tCWL if needed—and monitor stability.
Keep an eye on the benchmark scores; worsening performance may signal FCLK instability, requiring higher SOC voltages. Once you identify the top speed, run Linpack Xtreme for 10 cycles on the 10G preset to verify frequency stability. After that, focus on fine-tuning the timings one by one, gradually increasing until the system boots, then proceed to Windows and Y-Cruncher checks.
For subtimings, look for guides from others who’ve overclocked Micron Rev. E—consistency is key. If you find reliable subtimings, apply them carefully. After that, conduct a longer stability test (3-4 hours) and consider stress-testing your GPU to rule out thermal issues. Always confirm with a notification so we’re alerted to any changes.
