Almost forgot to cross-post this one as well.
As you know, the CPU microcode is used to fix some hardware related problems. Intel has it, and so does AMD. Usually you will not notice any of the errata (=problems) in daily computing, but sometimes it happens. I'm sure you all remember the famous Phenom TLB-bug
. Usually, it is very important to have the latest CPU microcode as that one would contain all the latest fixes. Sometimes you would actually want to use older microcode to have better performance. For example, in the Core 2 era we were all using an old microcode to get those really fast SuperPI 1M benchmark results.
compiled a list of the AGESA code versions of most of the 970/990 AMD motherboards for our reference. If you're using the Bulldozer patch, you might want to know what AGESA version you're using! It's possible that since this list, there has been BIOS releases with the latest AGESA code. If you find any, please drop a message in the forum.
Latest code versions
Due the old AGESA version the microcodes are outdated too:
Zambezi (OR-B2) - Installed: 06000626 (01/04/2012), The most recent version: 0600063D (03/06/2013).
Vishera (OR-C0) - Installed: 06000817 (05/24/2012), The most recent version: 06000822 (01/03/2013).
Version 0600063D (OR-B2) contains 10 errata fixes, while the 06000822 (OR-C0) fixes 8.
Zambezi microcodes marked with red > 06000629 still have the Valve CEG fault present.
Known Updated AGESA Bioses
