Hey folks – chasing some final RAM tuning feedback before I move to long-term stability testing. Wondering if my AIDA64 latency (66.9ns) is a bit high for 6000 CL28 FCLK 2200 with relatively tight timings? Included are my ZenTimings + AIDA64 results.
Questions:
- Is 66.9ns latency too high for this setup? If so, how can I tighten further (without pushing thermals too hard as I'm running a ITX/SFF build)? I tried testing in safe mode but it only made like ~0.3ns difference. I'm thinking of disabling GDM next.
- Any other tuning recs worth trying before I finalise? I couldn’t get CL26 stable even at 1.5V MEM VDD with looser timings, this setup gave better real-world latency. I think I'm stuck at 1.15 vSOC to stabilise FCLK so probably can't move up to 6200.
Bios settings not displayed:
- VDDG IOD/CCD: 1.05V / 0.95V (will test bringing down slightly, was focusing on stabilizing FCLK)
- MEM VDD: 1.45V (will test bringing this down slightly)
- Nitro: 1-2-1, burst 8x/8x
- GDM: Enabled (planning to test disabled soon)
- TSME: Disabled
- iGPU: Disabled
- SVM: Disabled
- Global C-States: Disabled
- Robust Memory Training: Enabled
- Memory Context Restore: Disabled
- Power Down Mode: Disabled
- Spread Spectrum: Disabled
- tPHYRL: Manual ->1 -> RAM aligned to 34
Preliminary Stability Tests Done:
- TM5 anta777 extreme + 1usmus configs – multiple passes
- Karhu ~10,000%
- AIDA64 CPU/FPU/Cache/Memory stress
- Ram temps were ~50 degrees celsius during the above.
