I put this together in a bit of a hurry at the weekend, and after years of using AMD kit was a bit surprised to find the base clock was not reported as 100MHz.
After looking around on the web I see this is what you'd expect, it's common on various gigabyte boards from H61 upwards, and on other makes. So is this just inaccuracy in the reported value by the BIOS, or a flaw in Intel chipsets which cannot maintain 100Mhz ? No one seems bother about it, I found no obvious explanation on the Internet. Guess I'll forget about it
The F13 BIOS on this board doesn't match the manual. You can't change the BLCK. The value of Vcore does drop 0.84v when running Linux without a monitor attached, so that's OK.
