Core i7 920 rev D0 stepping 5 :)

[jcniest5]

What are your mem frequency/uncore/QPI multiplier?

Mem freq is 1640
Uncore is at Auto (same as 8), result in a 3280

The Corsair works just fine using this setting, but the OCZ craps out each time even though it has the better timing than the Corsair. Time for RMA?

BTW, what does Uncore freq do anyway?

On the 222+ blck, I can run stable at 16x225 (3.6Ghz) but any higher than that the PC craps out. Vcore is all the way up to 1.35v something. Is this D0 a bad overclocker or is it just something I'm not doing correctly here?

Have you tried the 6x memory multi? I can't get my 920 stable too far over 4.2 with the memory on 8x. With the multi at 6x, it goes to 4.4 no problem even with the same uncore frequency.

First boot @4.4GHZ 1.328v(Idle) . This is not primestable for 24/7 yet (gotta work more on it), but I'm pretty happy with my D0-babe's first attempt.

Heres mine, still working with it have a leaky radiator so can't leave prime on for very long New radiator tommorow or next day and will try to push more.

I am still playing with my D0. mine is watercooled

12GB of ram is a pain to get settled down

This is just SICK!! What voltage/cooling? Most important, did you find that 112 PCIE yielded better results than 110?
RR, you obviously have great skill in OCing, only Anand Tech with a well stocked scientific lab and big budget has bested you. If you want to keep your hard-earned secrets to yourself, I wouldn't blame you, but if you want to share whatever magic settings you've discovered, I'd love to learn from you cause I'm stuck at 234.4x21 at low volts so I think there's more progress I can make. Anyhow, I sincerely hope you get all the accolades you deserve.

So you ended up with an Xeon, Sam? You may not recognise me here, but I posted a few times in the i7 thread at hw.no before you got banned with a different nickname. Same batch as me, I assume you got it from Digital Impuls?

Great result Sam.

Please not get banned here..

Great result Sam.

LOL, Thanks, but this not final yet. The best part is to follow (hopefully ), but over here, it is harder to get banned for good results, LOL.
