MSI Beta forum thread: https://forum-en.msi.com/index.php?threads/msi-x570-b550-beta-bios-update-bug-status.348919/

Has 1.2.0.1 for X570 Unify, Godlike, Ace and the B550 Unify, Unify-x

Appears to fix the L3 cache issue and is also updated to SMU 56.46

Current BIOS:

seems i have some weird issue with my L3 on my godlike board and i updated to the latest bios that was ment to fix this issue, why is my L3 worse after updating to the latest beta bios. ?
not just the numbers but look at the latency what the hell ? :/
 
I've updated to the a91 for the unify and I get something wierd when I hit 3600mhz/1800mhz - my memory becomes slower than 3533/1766 by a fair chalk! I don't know if my Mobo is increasing voltages at this point causing boost to not boost as high - does cpu clock affect bandwidth etc?

also which version of Aida is that? I downloaded the trail of extreme and can't find a test that does all the flavours like that ^ one. Thanks

on a 3950x with PBO on btw

Was it ok before you updated to a91?

Just wish i could figure out why i have really crap l3 cache bandwidth and latency LMFAO
and all versions of aida64 extreme edition have this cache and memory benchmark, but it will say trial on all the scores unless you register/buy it...

well I'm not going to buy it, so I'll just have to run the tests separately

Beta BIOSes don't guarantee anything - this is why they are beta - not stable.

Might it have something to do with your ram speed, are you at 2:1 or 1:1 given the 4000 speed?

Hi pal im running XMP for the first time this bios update allowed XMP to boot up so no idea whats causing the slow L3 :/

Interesting
How about setting something like 3600mhz 15-15-15 timings with standrad timing and rerunning just out of interest, likely it nothing to do with it, but would make for a comparison of sorts

Ok will give that a shot when i get back from work later on tonight and report back later worth a try lol :D
 
Ok fixed it not sure how i think i bumped soc and ccd and iod voltages a little more and presto working as it should now, the figures are there but the latency is still high for some reason lol

Your latency is likely high because you're probably running your memory uncoupled. If you check the memory tab in CPU-Z, does it say your uncore frequency is 1000 Mhz? If so, you are uncoupled which will be the cause of your latency. To get your memory coupled you need to manually set the FCLK either in the Bios or using Ryzen master. This needs to be set to half of your RAM frequency, so that would be 2000 MHz for you. However I don't know of anyone who has managed to get 4000 RAM running coupled and stable yet. I also bought 4000 RAM and had to lower this to 3866 and set the FCLK to 1933 in the BIOS. Once you get these two coupled, the 'uncore frequency' (which is your UCLK or memory controller speed) will automatically match the the other two so you can check CPU-Z again to see if you've got it right. Alternatively, if you download Ryzen Master it also tells you if you are coupled or not.

The latency figure of 67 isn't that bad actually for CL18 timings. It will likely only come down around 5 ns once your coupled anyway.
