There are no problems in other games. Only WOW retail is problematic. CL factory values for 2133MHZ.
I get the same errors with the memory of 2 different brands.
Now I have read something and downgraded the Bios version. I got the bios update before “AMD ComboPI1.0.0.3abb”.
I have been playing WOW for 5-6 hours, Error 132 has not yet given.
It currently runs at 3600MHZ of RAM and is set to CL15-19-19-19-36.
I will test for 2-3 days and share the result.
Some tasks are better at revealing memory errors than others, that’s why other games could not trigger it. Usual memory testing is done for hours of continuous work. BIOS screwup could also be the cause 
Hi,
Problem is solved … MSI MPG X570 GAMING EDGE WIFI installed the old version of bios and everything went well. I reduced the version from 1.70 to 1.20 and I no longer receive 132 errors: D
Did you change the settings of your RAM?
Are you using the default settings after the BIOS reset?
After installing the old bios, I changed the RAM settings. I set the 3600MHZ CL15-19-19-19-36-59 and the Voltage as 1.40v. I have been playing WOW with no problems for 4/5 days.
As the problem is not the RAM frequency or settings, I was still getting the error even though the RAM frequency is 2133MHZ in the bios version “AMD ComboPI1.0.0.3abb” and above.
Hey Beachîmsu!
Would you mind sharing some basic diagnostic data for your computer, so we could have a look at this from our end? Could upload the files to a service like pastebin and post the links here, if that’d be okay with you. 
There have been a few blips on our radar for hardware setups similar to the one listed in your original post, so we’d be very much interested to see if further commonalities can be found.
Hi,
Of course, I can provide the information, but I am sending DxDiag because it is over 512Kb on the site.
Please do not forget to delete the spaces before and after " . com" point.

I added in the Google drive link.

i upload mine aswell, i’m getting these crashes after a bios update aswell on a X570 system. maybe it can help a fix on your side.
i have Hearthstone crashes aswell since then. and only on blizzard games

Can you leave a memtest running overnight? Also continuous Unigine Valley demo/benchmark (and optionally Unigine Superposition and 3DMark Time Spy) - Valley seems to be better and “finding” system instabilities.
If memtest runs ok for multiple hours overnight and the Unigine stuff for hour or so then it will vastly limit the chances the system overall is unstable.
it was the bios upgrade on a X570 that was causing the trouble. i rolled it back to the stock version ( 8 bios updates ago) running stable for a couple hours now. before it would not stay online for more then 15 mins.
everything else was running fine on my pc, benchmarks, memtests etc
By now we’re indeed pretty sure that there may be some kind of fundamental microcode conflict between the Ryzen 3600/3600X series of CPUs and BIOS versions released after AGESA 1.0.0.3abb/1.0.0.3ab. Rolling back to one of these versions seems to fix the problem for everyone affected, as far as we can tell - it may not always be easy to do but the results do speak for themselves.
Thanks to everyone who shared their data, it is much appreciated. 
Hi, i’m coming from https://eu.forums.blizzard.com/en/wow/t/constant-error-132-crashes-for-last-2-days/136154/6
To confirm - motherboard is MSI B450 Tomahawk (non-Max) and I had to roll back to bios with ComboPI 1.0.0.3 ab - now WoW is fine.
I dropped the topic on reddit to see if it’s more generic: https://www.reddit.com/r/Amd/comments/glie0n/ram_stability_problems_in_wow_on_latest_agesa/ and it seems some people did experienced problems with newer AGESA.
Hello to everyone,
I replaced my 3600x processor with 3700x. I installed the latest version of the motherboard bios. I set RAM XMP profile 3600Mhz CL16-19-19-19-36-59.
I just changed the processor. Now WOW is running smoothly. I’m not getting any errors. Good games.
Version
7C37v192 (Beta version)
Release Date
2020-05-15
Easy test would be to fly in circles around the main street of Legion Dalaran. If that doesn’t crash then it’s rock solid.
Thanks for info, unfortunately that is not a solution for me since I dont have money to spend on new processor and the current is perfectly fine from performance point of view. Also MSI dont have newer bios for my B450 Tomahawk - last one is dated like November 2019 
.
You’re welcome. Pull the bios update to a lower version. This will work.
I know, I did but my older bios have constant issues with USB/sleep mode/etc so my choice is to have crashes in WoW or restarts to bios without hard drives
Ok so AGESA 1.0.0.6 bios for MSI B450 Tomahawk released few days ago doesn’t solve the problem. Just checked - crashed after like hour. Rolling back to 1.0.0.3 ab with bugged hibernation :/.
you can comment on reddit so that AMD CM that commented there knows it’s still a problem.
