Hi guys, recently getting into ram Overclocking and had a few questions, firstly my specs are:
-R7 7800x3d
-2x16gb corsair vengeance 6000 cl30 (pretty sure Hynix A Die)
-MSI B650 gaming plus wifi
-RTX 5080 running +420, +3000
My Stock Expo timings are 30 36 36 76 which had nearly 80ns latency which i feel is absurd compared to what i‘ve been seeing others getting online. I had put custom timings which are 28 36 36 28 and got 69.7ns on Aida64. I have all custom subtimings as well.
If you guys could help me out with voltages/ suggesting whether trying to run 6200cl30 is better/timings improvements i would be extremely grateful!
Also, i was able to run -25 curve optimiser before fiddling with the ram however now i don’t think i can run stable at that level anymore. Is it worth trying to run curve optimiser at a lesser extent? -20/-15 maybe? Or is it worth it at all and i‘m better off leaving the CPU stock and going all in on ram tuning. Thank you!

I think that might come down to everything you have running on the background.
I have the same CPU with 2x32GB also Corsair Vengeance 6000 CL30-36-36-76 (but running at 6200 CL 28-35-30-35) and my latency result, right now with Insta and Edge opened, was 67.5ns.
If I run the benchmark after letting windows boot and wait a minute or two for every app to stop checking for updates or whatever, this result comes down to around 62ns.
Running the benchmark in Safe Mode gives me the best and more constant result, which is around 58ns +/- 0.5.
So, now I only run RAM benchmarks in Safe Mode, all the stress tests in “normal mode” of course, as I want stability in the real environment.
Test on a fresh boot, all useless programs closed. Here are some BIOS settings to improve latency, you can probably get close to 60ns
SVM = Off
iGPU = Off
Bank Swap mode = Swap APU (only works if iGPU disabled!)
TSME = Off
Data scramble = off
Memory Context Restore = Off
Power Down Enable = Off (only works with Memory Context Resotre = off)
then you could also try to run Nitro with either
1-2-0 or if that dosnt boot 1-2-1
Robust Training Mode on
Both burst x8
and you could also try to run GDM=Off but this could be unstable with your timings.
(GDM Off SCL must both be 5/5!)
