My fellow ASUS AM5 users...

I always had issues with my new AM5 PC build from the start (parts list at the end of this post). System could not run any 6000Mhz RAM kit no matter what I tried. 5600Mhz CL28 worked most of the time, but on some boots it just became unstable (game crashes, glitches, bluescreens) and needed restart (thus retrain ram). From 14xx to 1616 BIOS versions it behaved all the same with slight variations. I am using Karhu RAM Test and errors were wierd. On some boots I got errors right away at 7%, but sometimes errors came in after 1000% no matter the temperature of memory and sometimes no errors at all. I know I wasn't alone with this, there were many reports of similar behaviour on diferrent ASUS AM5 boards, but mostly B650 ones. I found no such problems reported on MSi or Gigabyte.

Yesterday I flashed new 1634 BIOS with AGESA1007b and everything works right away. 6000Mhz CL30 (with Hynix buildzoids timings) 5000% no problem, MemTest passed too, tried on multiple boots. Now I'm testing 6200-6400 and it looks stable too.

Can someone else here confirm or deny that 1634 is finally fixing issues many ppl had? Would be good to know if my system is just a fluke or things are getting better with ASUS.
