Welcome to the Ultra High Performance League. You are now among the Greats! :rofl:

a couple of questions here

does 200 x 20 take more voltage than 190 x 21?

are most of you going with ht on, turbo on?

accidental double post..

Just got my core i7 920,

S-spec: SLBEJ

Batch #: 3913A909

Anyone heard anything yet?

Not bad chip...210X20...Vcore : 1,425 V

I have just started to play around with my D0 3912A888 chip. ATM (my first boot) I run 181x21 with vcore 1.2V in bios, 1.35V QPI and the rest auto on my class. I have pass Prime for 2 hour now. I can not expect a very high oc now because the temp in Sweden are hot atm.
I question....will it help to reduce the IOH PLL and CPU PLL Vcore below 1.8V? I have read that it not effect the temps, right? But why do you reduce it any way?

Update:

186x21 with 1.2V in bios also pass Prime95. It seems to be a rather nice chip!

Batch "3849B018"
Cooled with an EK supreme, D4, and 3 x 120m RAD.

This chip definitely has more in it, but my temps start to get to high for me.
So far max temp is 80 in Prime and 75 with WCG.

4.21GHz

4.315GHz

That is one hell of a chip Blazzed. Congrats. :clap:

I've got the same chip, it's a hot one no doubt.

4315Mhz, whau, great OC! How do u help it more vcore in next OC? About 1.35V?

I can get these which is the likely best and what can I expect?

3912A859
3910A329
3913B213

Thanks.

Here is my Xeon W3520, batch 3844A704, ht on, turbo on:

I've got the exact same batch chip as you, MaByBoi (Retail Edge proc?). It will be very interesting to see how we compare as I'll be running the exact same RAM and PSU as you, but with a DFI UT mobo instead of the Bloodrage. Proc is here, all other components will be arriving this Wednesday, though I won't be able to assemble/starting testing until early next week. Will be interesting to keep tabs and see where the differences fall out. :cool:

Ill be running my current system in about a week or two, need to finish painting, assembling, cabling, and get water cooling on it! and my hard drive failed... set me back an additional 100$ CAD... :(

I am going to buy i920 , Does anyone know anything about this BATCH : 3910A366 (i920 , D0) ??

Is that you het! It's me disso! :up:

Just received a 3912B185 920, will be installing it tonight under a TRUE w/Washer Mod on a P6T-SE board.

I can't find mention of a new batch yet.

It is me Disso! Nice OC you got going on there!

hi i just change from my trusty 920 co @ 4200 to
the 920 D0 3913B213
with 1.425 v for cpu & 1.38 for qpi/vtt now at 21 x 215 = 4518:D
thats with out trying :up:

3.9GHz @ 1.2v ALL motherboard voltages stock/lowest. Will be pushing for more this evening. :)

Give some screens , what about temperatures ? AC or LC ?

Try to push 4Ghz+

Air cooling with a TRUE. 4GHz was easy on my last D0, I'm just testing the board with this new chip. The old D0 needed silly voltages on the board for these same clocks.

EDIT: I'll get some screens tonight. Temps were about 72, 68, 72 67. My cores aren't equal on this one but they were on my last at the last was a lot hotter too (batch 351A258).
