As he said in the previous message, there are almost never changelogs for microcode updates.
I do, however, have to disagree with *never* disabling microcode updates. If I recall properly, the AMD Phenom II 720 was able to be unlocked to 4 cores via a misconfiguration that enabled it with ACC. AMD later corrected this issue with a microcode update. True, some motherboards worked around that fix a different way, but if you had a first gen board with ACC support you *had* to have the old microcode for it to work. The update killed your free core :) On Jan 17, 2011 3:06 PM, <meino.cra...@gmx.de> wrote: > Volker Armin Hemmann <volkerar...@googlemail.com> [11-01-17 20:16]: >> On Monday 17 January 2011 18:21:48 meino.cra...@gmx.de wrote: >> > Hi, >> > >> > I have two questions: >> > >> > 1) Do I have to enable microcode updates in the BIOS of my Crosshair >> > IV Formula to activate microcodes push in the CPU by the module >> > "microcode" ?
