I've been running the ABIT IC7-MAX3 with Beta BIOS 12 and have noticed some issues when running 2.9V and above. Anyone else out there having the same issues? If you are let me know as it will help the review on the board and I can pester ABIT to get it fixed if it is only BIOS related!

This seems to be a common issue with this board. How is the new bios working?

I got news for you, remember news is rarley good!
The IC7-MAX3 has problems with VTT and vDIMM over 2.8v. VTT is the DDR termination voltage and is always half of vDIMM. Now on the MAX3, VTT is half all the way to 2.8, above that it fluctuates, for example @ 2.9V VTT is 1.3, @ 3v it is 1.35!

Another problem is vDIMM fluctuations, vDIMM rarley stays at what its meant to over 2.8v but fluctuates wildly. When u set it to 3.1v it is more likley between 3v and 3.2v.

Fortunatley there are mods to fix this, which can be seen in this thread in the abit forums.

Instructions for the mods are avialable here!!

Good luck! :)
