Nice run

Grest score. Strong rams.

Good Score. End of September we'll see if this is the Limit of the CPU?

I don't sandbag, so unless I run this on LN2/dice this is the end.

DFI is the secret :-)

Very nice! DFI is not the most efficient board out there. For example, 790X-UD3P is faster. Interested to know how much have you gained with manual registers tweak (if you have used any).

Damn dude good stuff!

No register tweaks. IIRC I checked with Pmem and it opened, but I didn't know the offset to find the used space.

Meaningful MSRs on AMD usually start from C0000xxx, C0010xxx and C0011xxx.

DCT0 is bus0/dev0/func2 registers from 040 to 04C, DCT1 is 140 to 14C

Low timing registers are F2x[1,0 ]88 and high timing registers are 8C. There are also 90 to A0. You would probably need to set DCT0 only and it will sync to DCT1.

Not sure if any of those would be helpful, since it requires studying the BKDG for family 11h 10h and I guess most things are already covered by MemSet and bios.

But it possible to have something that is not exposed and can be tightened further, especially the NB registers.

I am currently busy with Ryzen, but might play with K8 later.

PS: I was looking at 11h, 0Fh is a little different, but addresses should be similar.

Very nice stuff Nox, grats on the gold :D

I assume that ud4p should have similar mem effi? hopefully, lol

Amazing score man, I think this is the target for future 6400+ bench sessions to come
