Hello, I’m trying to achieve as low latency as possible on my Gigabyte Z790 Aorus Elite X (Rev 1.0) and the current latency in the AIDA readings is not something that I was targeting. My current configuration is fully stable after a couple of days of testing in y-cruncher vt-3, Karhu, and OCCT Ram + CPU test at SA 1.3v, RAM VDD 1.5v/VDDQ 1.455v, CPU VDDQ 1.4/VDD2 1.35. The memory’s XMP is 7600CL36.
What I’ve tried and found so far:
1. tCL = 32 at VDD = 1.55v/1.6v only results in even higher latency and errors in tests.
2. Lowering tRCD, tRP and tRAS by 1 – errors in tests at VDD = 1.55v or 1.6v
3. tRFCpb < 600 doesn’t really change anything except that it reduces stability of the system
4. tREFI at 131000 increases latency
5. SA < 1.3v voltage – unstable while gaming
6. 7800MHz at 1.55/1.6 – errors in tests
Not sure what I should try next, this is my first time I overclock DDR5. I don’t like the idea of lowering frequency unless it is not a compromise.
