Post subject:  Topsecret's I920 Overclock results

Asus Rampage 2 Extreme
OCZ 4 GB 12800
GTX 280 OCE
Coolermaster V8
Velo 300GB for OS
2x 500GB Raid 0 Gaming

@ 3.8 Ghz

SM 2.0 7835SM
MS 3.0 8524
CPU 7310

Total 20090 Marks

Now this wasn't as fast as my Q9550 results. But I did have a 4870X2 as well. which would have made up the difference im guessing. If I had it still I would try.

I will be trying some more overclocking later


Temp results:

Min: 38,38,39,40C
Max (During the CPU Tests): 77,77,74,73C

What were your voltage settings?

How about running a 200 x 21?

Post subject: 

200 X 21 isn't working atm. Don't know why yet. I havent done a overnight bulletproofing as well. For the time being tonight I have been optimizing my GTX 280.

I would take suggestions

With the current OC i'm at 1.416v
QPI Link @ 3420.2

4.2 Wasn't stable what so ever.

Had to bump my voltage to 1.45vcore
Dram Bus to 1.64v 1.67 being the limit
200X21 with Turbo mode on
and qpi/vtt to 1.360v


Not totally sure these are accurate but im going to goto the bios and do some tuning :)

HT off saved me mucho temps
