Man, many thanks for your hard work. I spent whole day yesterday using dram calculator for zen2 on my 5800x [zen 3] and played around to no avail. Ended up going back to 3600 14,14,14,30,70 for my stable Will use your method when i get home later and see where I land

Curious about this as well.

Manual overclocks and XMP profiles past 3200Mhz resulted into no boot, I couldn't even get into windows to check on the WHEA errors At 3200Mhz and below there were no issues, had looping 3DMark Timespy tests back to back for like 2 hours. Now at my 3600Mhz CL14 [Manually tuned off of the XMP profile] I'm not seeing any Whea errors, it's weird though how some were getting them and some weren't

Thanks for defining BETA for the users here. The site is really slow atm, don't know why. In any case for those with x570 or b550 boards go to the link. I am able to use my XMP profile 3600mhz CL14 as opposed to being limited to 3200mhz previously

https://forum-en.msi.com/index.php?threads/msi-x570-b550-beta-bios-update.348919/ They released new BETA bios that fixed the FCLK instability.

Nah you're not going to be able to..

4 sticks of single rank ram is identical to 2 sticks of dual rank ram Provided you want 4 sticks, you'll have the optimum setup, do not go 2 sticks of single rank ram.

As far as I know, generally speaking 4 sticks of SINGLE RANK memory and 2 sticks of DUAL RANK memory is best Followed by 2 single rank memory I don't know about 4 sticks of dual rank memory

Thanks! Let's hope for this BIOS update to allow 2000Mhz FCLK My ram is supposedly getting really good OC so I'm hoping for some nice clocks/timings.

Ok so generally speaking if I can hit 1:1 mCLK and FCLK I don't need to worry about much else in terms of IF tuning? [ram timings aside] Or would it be better to see how far my FCLK can go based on silicon lottery and try and OC my mCLK to the optimal number? [300Mhz more than FCLK]?

I never knew about this.. Once the XMP issues through bios factors are fixed, my cl14 3600Mhz with no no additional overclock as FCLK at 1933 to be most effective? I thought it needed to be the same for that 1:1 efficiency Edit: Oh and 1800 FCLK as well I see. Wait im so confused now

Isn't your testing a moot point? There really is no benefit to go beyond 3200Mhz if the FCLK can't keep up right? Or are you doing testing just to try and diagnose where the specific problems come from? Not being argumentative just curious as im learning things as I go as well

I see a lot of users on Reddit with WHEA errors too.. I can't make out if its BIOS or Hardware related but I guess it'll be known to all once the fixed BIOS comes out and people are still get WHEA errors.

You seem like one of the lucky ones. With the specs in my signature, I can't get past 3200Mhz on RAM or 1600Mhz FCLK

I feel bad for their building and employees but not for their lack of preparation and testing of the bios before release. People are saying the previous 1.0.8.0 AGESA are having less issues.
