Cant get back to 3733mhz on my ram or 1866 fclk with this update, B550-E, 5800x, I have no idea why, it won't even boot, so rolling back to the last one. just a heads up people.

Its working good for me

How does it improve system performance ? What exactly does it change ?

I've heard answers from politicians that are more informative than motherboards companies when it comes to BIOS releases.

I had the same issue until I realized the profile corrupted or changed so it appears they are not compatible. I manually reset things and got back to 3733mhz with 1866 fclk. Still cant hit 1900fclk

I will be doing some testing later but seems ok so far with a few quick tests.

**Quick update: Had several game crashes in a row then finally resulting in BSOD. It could be firmware related or maybe I didn't get all my ram settings the way they were set before since the Profiles were not compatible. I went back to 3501 for now for stability. I will wait for an official version or a new beta.

Are these the same settings prior to the FW?

Also are your set levels (v) close to what its reading?

Interesting development today. I had some time to kill so I decided to document my entire bios. Flashed 3601 again and reconfigured everything manually. I booted system, ran a few stability tests and gamed for an hour or so. No issues this time so I think I must have not entered in my timings properly last time. I will run this for a while and see if I notice any differences.

I played around with voltages and tried FCLK 1900 and no joy. Interesting thing is I said let me try the next step up @1933 and the system posted and actually booted into windows but got wonky from there. I went back to bios and it was super sluggish so I had to CMOS reset again. I tried to tweak voltages and even go back to auto but nothing made a difference. Not sure why it would go 1933 and was the ram unstable at that speed? When I have some more time I might try 1933 with ram clock lower just for verification purposes.

The FCLK should be 1/2 of what your RAM frequency is set at. If it won't boot with it set like that in the BIOS, then your timings and/or voltages need to be adjusted.

Yes I have been running at 3733 Ram and FCLK 1866.5 which is 1:1 , if I try to go to 3800 and 1900 no joy. For testing purposes only I also left FCLK at 1866.5 and pushed Ram to 3866 breaking the 1:1 but seeing if memory was causing the issues. I ran a few short tests and had no issues. I really think it is just an issue with the memory controller. No voltage changes seem to help so it might just be my limit with this chip. It is disappointing because the Ram OCs very well 3600 up to 3866, 4000 was a no go at stock timings and I am more interested in latency at this point).

Thanks for the reply.
