The gig ud3 is very different then the ud5/7. It's not just the cooling. It has the same older vrm and power delivery that the 7 and 8 series boards had. It's a great board for phii, but it can't even handle an fx-8120 at stock if you disable the throttling. They don't have an option for it in the bios because it can't handle it. I did a work around to do it, and it killed both the board and CPU. Again at stock speeds, using prime95. Vrms and nb were pushing well past 100c.

Negative sir, the revision 1.0 boards were that way. The 1.1+ revisions all offer LLC, which is exclusive to digital Circuits.
I have the ud3, revision 1. and your findings are COMPLETELY FALSE. My VRMS do not go over 60c. (i did add a fan to that region) The throttling was a bios problem, and has been fixed, but if you disabled cool and quiet before it was fixed, throttling was only a issue with cool and quiet enabled. I can clock my 8120 to 5.2ghz on the UD3 revision 1.0. No throttling or anything nasty like that. Maybe you should have tried to update your bios.....
The UD3 is a great board for the FX processors, and soon to come FX piledrivers.
