Good question huh? Yep sure is. Also what is "TJ" :) ??
Had a better look at the Gigabyte sheet.
It says "AMD next generation FX".
Vishera is no next gen, it is almost two years old already
I assume Gigabyte refers to "TJ", which still should pop into AM3r2.
The sheet is for Rev 3.0 990FXA-UD7 which has some changes to the VRM.
Yet it appears to be a multiplied analog VRM.
Interesting times ahead ;).
