First i7 920 D0 Step @4710Mhz HT Enabled

[eva2000]

Yes not as good as other i7 920 D0 steppings in terms of vcore needed - but runs alot cooler than alot of D0 even with high vcore applied

Pushing my i7 920 3851A368 D0 to the max with HT enabled now. Seems cpuz validation is higher than my i7 920 3836A756 C0 when HT enabled - 4710mhz vs 4669mhz and D0 also has slightly higher max HT Enabled Super Pi 32M cpuz speed - 4685mhz vs 4618mhz. Only difference is for C0 tests I used single 8800GT while D0 was using 2x HD4870x2 Crossfire installed.

Like my C0 stepping, this D0 seems to handle high vcore with relatively low temps !!!

System:

• i7 920 3851A368 D0 stepping
• EK Supreme LT 1366 / FESER 480 / MCP655
• DFI UT X58-T3EH8 04/28 beta

very nice! How loud is your rig? And btw the DFI Lanparty utility doesn't read accurate temps Im told

 

[eva2000]

thanks

DFI SG app under reports idle temps by around 10-15C hehe

loud is relative.. loudness part is of course my 2x HD4870x2 in crossfire

Nice, where is a vantage run? Would have got awesome scores!
I am going to skip D0's, want a real tick to come out
Just hope my 965 will hold 30% of it's value at least lol...

Can't believe there have been so few replies to this. I have to say: Bravo Man!
