Bad news with the 3.3 revision. I got a hold of a 3.3 and tested it out.
With the 2.0 revision I was hitting 3.6 Ghz with an E6600. The 3.3 revision won't even post for me at 2.7 Ghz. All the same hardware and all the same bios settings. What the hell did they change??!!
I would like to say I fully endorse this post, while I've never previously owned a DS3 1.0 or any other 775 board, I can say my BRAND NEW DS3P 3.3 with F4 Bios (only one on the website?) and E4300 is barely able to do 2.7ghz!
