how to improve g.skill ddr5 6400 cl32 latency
hello everyone i have asus z690 hero i9 13900k and 2x16gb g.skill ddr5 6400 cl32
i overclock the memory to 6800MHZ when i overclock to 6933 i get memtest eror when i overclock to 7000MHZ no boot
so i want to squeeze the memory in 6800MHZ to max preformance and to lower latency as lowe as possible

thanks for the help

If A-Die, just run the Asus 7600 Preset and change TREFI to auto. If you have a ram fan, you probably could try running 65536/130560 for TREFI. You have to run TM5 to test and see how you fare for temps.
That's even provided your Z690 Hero can run 7600 with no issues. If you have M-Die, you can try my 6800C30 profile if you want but it runs 1.55V VDD/VDDQ.

Try on auto first and see if you pass. You can't run TREFI at your current setting unless you can keep temps well below 40 degrees. If you can pass on auto, try 65536 and if you can pass that, 130560. If you have no ram fan, I suggest you keeping TREFI on auto.

I also have a 6800CL30 profile for my M-die that I just finished. If you're interested I'd like to compare. I will post or DM you mine tonight when I'm home.
Can you pm the bios txt file or post here would be great. See what works for you.

Unfortunately I've already moved to A-Die. Thanks for the offer though. 👍

My mobo has super low VCCSA for some reason. It defaults to .938V. I have it like +90 mV in FIVR settings. Just got this setup stable, ran 65000 REFI for tests, tho. Even 1C exterior temps and a Corsair Vengeance DIMM fan at full speed with my bedroom window open couldn't do MAX REFI temp-wise.
If you look at SS in HWInfo it shows the mobo is adjusting to a bit higher, especially on VDDQ, but BIOS settings in HWInfo nomenclature for RAM voltages are:
VDD (SWA).............1.54V
VDDQ (SWB)..........1.49V
VDD2........................1.36V (Called VDD_CPU Voltage in ASRock Bios. @buildzoid says it is safe to run up to 1.6V as IS NOT applied directly to CPU. He also mentions there is a sweet spot for each motherboard. Mine's sweet spot is 1.36V across many different RAM speeds and voltages)
VDDQ TX.................1.45V (Called VDD_IMC Voltage in ASRock Bios. @buildzoid says it is safe to run up to 1.45V and it IS directly applied to CPU)
VCCIN.......................2.00V
VPP (SWC)..............1.90V
VCCSA......................1.008V (Not a bios setting on my motherboard. My motherboard defaults to .928V VCCSA and I added 70-90 mV in FIVR, don't remember exactly)

I just tried googling it...how do I generate a .txt of bios settings?
I have ASRock Z790 PG Sonic motherboard.

Yep. Tried different combinations of p/e/ring ratios, this ratio scaled better for benching and ram bandwidth. Its 54x all core p, 45 e, 49 ring.
