Can't increase tREFI

[ir_cow]

BIOS updates can do what your described. Especially if you don't set the SA/TX/VDD2 voltage yourself because auto can be different per BIOS version.

Increase trfc a bit and see if that allows you to adjust trefi

Hmmm you might be on to something. All I ever changed was vdd and vddq(cpu) to 1.3 (tried going lower like you suggested but wasn't stable unfortunately) and vddq(ram) and vdd2 to 1.5v. I never did touch SA, left it on auto. I don't remember exactly where it used to be, but I swear it was around the 1.15 to 1.2 area (could be wrong) where now I see its more in the 1.275 and up territory . I just changed it to 1.15. If that doesn't work I'll try 1.2. Or maybe just 1.1? Anyway, I have something to work with now. Thanks. Worst comes to worst, 32 38 38 can't be that bad.

What is TX? Is that known by something else maybe? I'm on a gigabyte board.

Thank you! Changing SA to 1.15 worked

TX is short for VDDQ_TX. Sometimes called VDDQ_CPU. Depends on the motherboard.

Yes. 30 Minutes Anta777 Extreme, 30 Minutes OCCT and 30 Minutes with TPU's MemTest64

TPU memtest is useless, don't bother, but 30 minutes with anta777 and occt is hardly what I would call stable, I had my memory error out after 2 hours on anta777 before

Have you updated your motherboard's BIOS recently? Updated microcode on current batch of BIOSes behaves differently than the previous ones pertaining to tREFI and tRAS. Previous one I had 131072 working, current BIOS it doesn't boot - 65535 clocks is fine. Performance impact from this isn't noticeable.

0.05V makes that much of a difference?

Yes, in my experience this is also the case. If your SA or VDDQ/VDD2 voltages are off even by a little bit, your RAM may not be stable. Raptorlake IMC is very finicky, even on binned SKUs like the 13900KS (my experience is with this CPU).

Its vddq_cpu, gotcha. I wonder if the bios increasing SA voltage is in anticipation of 14th gens supposed greater memory support. In that case you'd think it would distinguish between them, wouldn't you?

Bios update messed with your config too eh?

Nah. The 14th gen is Raptor Lake with a new name. Probably some IMC improvements, but I can't see the voltage increasing since the underlying architecture is the same.

In a sense yes, but this BIOS also resolved a weird problem I was having with my computer failing to enter a low-power state, lingering zombified instead of sleeping or shutting down. Given I'm on a Z690 Ace I can only imagine the horror early Alder Lake BIOS was...

Ah yeah I remember you mentioning that before. Glad its solved.

Hmmm well for some reason it increased. I even noticed that it had gone up. Don't know why I didn't think to change it before you brought it up. Anyway, all's well that ends well I suppose.

I downgraded my BIOS and my RAM is now perfectly stable with 65K tREFI again. Seems like it's a BIOS issue.
