Just got mine up and running. Was able to get into windows @ 425 FSB but like everyone else it needed more voltage than I was comfortable with even just benching. The EPU driver causing crazy voltages is strage. I've seen the SB go from 1.55v to 3.05v in Asus Probe. First I installed Vista 64 on the shipped BIOS 404 with 4GB of ram installed. I also installed all drivers from downloads from asus to use the newest ones. System would freeze up every now and then and it would come back alive after 30ish seconds. Was definitly strange. Loaded 701 BIOS and removed 1 2GB stick and reinstalled vista. Well the install was very lagged as others have said. It didn't do this with the 404 BIOS.

This time I installed all the drivers from the CD. It installed the AISuite which actually caused me so much grief with my Keyboard I almost threw the kb out the door. System was stable until I tried to use the keyboard when it would crash the current program that had focus. Took me lot of fudging with the BIOS to finally think about removing the AISuite which of course was the issue.

My First impressions with this board are so-so. I loved my XBX2. I upgraded to this for the 2x 16x PCIe. I'm hoping for a good showing from ATI on the new video cards and I plan to run a nice crossfire setup when they come out.

I have several different RAM's to try out. Crucial Balistick PC6400 and PC8500's to try out on top of this G Skill PC8000 2x2GB which are really nice as well. FYI I'm using a 830w Silverstone single rail PSU as to ensure I wouldn't have any power issues with a certain rail maxing out causing system instability. I hope to post back later tonight with a decent OC. So far the sweet spot for me is 365x9 with the Q6600.
