Ket I'm working right now so I can't try anything at the moment. Few things I can tell you as I've noticed that since I built it three weeks ago. I received my board with version 1.6. Without any bios changes, I noticed it wouldn't turbo up to 3.7. I have tested it while playing BC2 and using LinX also. So I flashed it to 1.8 soon after it was released. I again noted the same issue. Now I can set the multiplier to whatever I want with no other change and it will go to where I set it. So during lunch I called a friend with the same board. Only difference is he has a 2600K. He reset his bios 1.8v back to default. He tried LinX and BC2 also. It would only turbo up to 3.5. Notice both chips only turbo up about 100/MHz from their stock speed. It's not a big deal as I can obviously OC my system without issue and at low vcore to boot. But it's something I've wondered. Compared to my P8P67 (with 2600K) board, it auto turbos to 3.8 in stock form under any load I give it.
