Hi guys. I run a Pro Z690-A with four 32gb memory modules. 128gb is the bare minimum for what I have to do, while ram speed is not so important.
More precisely, they are Kingston HyperX 2666 MHz modules, CL16.

Can I incur in stability problems? Should I manually decrease speed to 2400 mhz or increase CL to 17 in order to give the memory controller more headroom?
I don't see a reason why should you have any problems with that setup. Only possible problem could be memory support but with each new bios version that is also fixed. If possible stuck to the memory models which are on the support list. If the speed is not that important than put it on fastest jedec timing which works without errors and you are set.

Thanks. I asked because I found this thread..: https://forum-en.msi.com/index.php?...single-vs-dual-rank-stability-testing.363139/

If anyone has i7 12700K/KF, can you please check what's you Vcore while running on stock settings while on 4.7GHz (e.g. Cinebench R23)? What max powerdraw and temps you get using stock settings and which cooler?

Also, did anyone have issue like this: I undervolted using Adaptive+Offset, Vcore 1.25 - 0.025 offset, LLC mode 3. This gives me Vcore around 1.16-1.175 on 4.7GHz. What happened is that after waking PC from sleep and playing a game, Vcore was back to stock, 1.24-1.25 and PC rebooted at one point. After that reboot, it continued to work like I set it in BIOS with undervolt.

It was a learning process for me that modern motherboards like MSI sort of "overclock" by default. I have 12700K and the ways that I adjusted this myself were to change the Long/Short power limits to something like 190 and 202, and then instead of specific undervolting you mention I changed the "CPU Lite Load" from Auto default (9?) to 6, after stress testing and noticing some weirdness when attempting "3." And I set Turbo Ratio, not All Core. My cooler is NH-U12S and max temps/watts after a little Cinebench and LinpackXtreme and Prime95 are around 74C/154W (I think they were higher with the original default high Long/Short and CPU Lite Load).

Not sure if this is Vcore but HWiNFO64 shows Core VID ranging from .7V to 1.32V if I've run Cinebench R23 (I forgot to check after running LinpackXtreme and Prime95).

I do use Beta BIOS 1.26, I had trouble resuming from sleep with XMP memory on original BIOS.

I have same CPU and cooler, and running CB on stock power resulted in thermal throttling because I would reach 100C in 10 seconds (Power load was around 240W). After I changed Long/Short power limit to 200W I can run it for hours and temps go to max 92C - not ideal but a lot better than before.

I guess that this cooler can not chew more than 200W but I didn't know that before I bought it.

That's near impossible. No way that even at 240W the cpu can reach 100C in 10 seconds.
Without power limitation I get ~83-84C on a 12700K with NH-U12A, which is almost the same cooler.

I think that your cpu and cooler plate don't make proper contact.

I tried it few times already, dismount and mount cooler but no changes, even changed the paste from the one that comes with Noctua to MX4, but no difference at all. Since I limited power to 200W it all works great. But these temperatures goes only with so high if I run AVX2 benchmarks, with other it is ok.

Another thing.. I tried to upgrade my BIOS. Put it on the root of a FAT32-formatted pendrive, and rebooted in M-FLASH. The BIOS updating program does NOT see the bios file on the pendrive. Then I tried to rename it MSI.ROM. No effect. Tried other pendrives. No effect.
So I tried the bios flash button method. I inserted the pendrive into the bios flash port, and pressed the button. It blinked red for some seconds, then turned red but not blinking. Half an hour has passed..
What's the issue???
