Configuration Details
Yes, that's what I meant. It's probably due to the settings you configured earlier. If you enabled auto and retrained, performance should reach around 80/60. Keep in mind these results can vary based on the board and BIOS version.
Varies by perspective. I believe 1.65V is acceptable for long-term use with DDR4, though some prefer keeping it below 1.5V for better stability. Your screenshot suggests you're not altering the IVR Transmitter voltage (VDDQ TX), which many overlook. That setting can influence memory frequency more than VDD2 (ASUS's MC voltage), and the optimal range shifts based on various conditions.
I really believe I took more than I intended here. You're correct. I'm not experimenting with TX just to add another factor that would be hard to manage given the time constraints I have. I feel secure with my MC voltage now. That doesn't imply I need more than necessary. Right now, I'm working to identify the failure voltage threshold. I'm checking 1.45v on the MC for another 15 minutes to observe if it passes. If it does, I'll reduce it to 1.425v. I wouldn't be surprised if it succeeds. My concern is that after the dropout point, the value is very close to what Auto shows. Once I determine this failure rate, I plan to adjust the timing and explore possibilities without extra voltage.
In the order of adjustments, the primaries exhibit some slack, but practically only 2-4 ticks are available on each, which shouldn't noticeably affect performance. The tRRDs should aim for 8/8 instead of the 16/8 you configured, and many systems will settle at 8/4 or lower. Although the performance gap between 8/4 and 8/8 isn't huge, these settings tend to fail quickly if issues arise, so it's worth testing. Make sure you also reduce tFAW to 16 if you plan to adjust the tRRD intervals. tRTP is generally quite flexible, with most systems reaching 16, though some manage 12 or even lower. This timing tends to stall at 12 for boot stability but becomes unstable at 11, making it a reasonable choice despite the minor impact on speed. tCWL (ASUS BIOS feature) usually allows low latency relative to CAS, with most A-die boards hitting 20 at 1.5V—though this has little practical effect, so it's often unnecessary. The tRDRD settings should default to 16/8, as most boards can reach that. Some achieve 14/8 at higher speeds, but such speeds are rare above 7200. tWRWR should target 12/8, ideally aiming for 10/8 or 9/7 (rounded to the nearest even), which are essentially the same. tWRPRE timing should be around 60, though this can vary based on CAS latency—tighter latencies may not always guarantee success. The remaining parameters usually don't influence performance or relate to power-down mode, which you should ideally have turned off.
Power down mode refers to a system state where all operations cease. It is related to the MCH full check, ensuring everything functions correctly before shutdown.
Power Down mode is a feature that reduces power consumption by turning off half of the memory stick when not in use. It can save a small amount of energy, around half a watt. This approach works well on laptops but may not be practical for desktops. Disabling it on ASUS boards usually involves adjusting the tPPD timing to zero or finding a specific setting like "Power Down Enable" that needs turning off. MCH Full Check is another setting whose purpose I’m unsure of, especially since I haven’t used ASUS boards in a while or been familiar with their naming conventions. It might relate to Fastboot, though I haven’t had an Apex in a long time.
I adjusted the tRDWR_sg and tRDWR_dg values as suggested, but it kept crashing. If these changes don’t improve overall performance, I’ll skip them. It seems I have some flexibility with the voltage settings. I’ve only tested Y-Cruncher and 20 cycles of 1usmus so far. After that, I plan to play with Absolut and Karhu. Before then, do I need to tweak anything else or be satisfied with my current setup?
