Well I picked up the i7-920 D0 today. Took a while to install it since the CM V10 cooler was a b@tch to take off. I had to take the mobo out since the opening on the tray was not located center to the backplate on the Revolution mobo. It was on the eVGA. I had to use a socket wrench to take the V10 off since I couldn't find the nut wrench adapter that came with it. Then I lost one of the washers (found later stuck to the socket wrench handle
). I had to take one from the CM GeminII cooler I had laying around. After I reinstalled the V10 the temps where high. Re did the whole process again and upon the removal of the V10 I notice I prob used too much TIM on the CPU and cooler. So f@ck that. I installed the TRUE instead with push/pull fans. Lot easier to install and move around.
The D0 went to 4ghz at Vcore 1.29 with the Bclk @ 200 and multi @ 20 (non turbo) and passed the OCCT test. Max temp on one of the core was 70c. Started OCing some more and thats when I started hitting various walls. Tried multi 21 to get 4.2ghz but did not pass the OCCT test. System rebooted, sign of lack of voltage on CPU. Started to increase the vcore all the way up to 1.35v (where it was at with the C0/C1 bclk 195 x20 for 3.9ghz) but one of the threads crapped out doing the OCCT run. Then start to adjust the bclk keeping the multi @ 20. System booted with bclk @210 giving 4.2ghz but failed OCCT. Temp got over 80c, my cut off. This was all done with all other settings on auto. Finally get a stable 4.1 @ 1.34v using bclk @205 and multi at 20 non turbo with max core temp @ 75c.
Bottom line is that if you already have an i7-920 C0/C1, its really not worth the upgrade to go to a D0, IMHO. But if your are getting an i7-920 then look for the D0 revision if possible.
