Core i7 920 rev D0 stepping 5 :)

[ShoNuff]

What's your batch#? Did you order it from that Pao_Revolt also? Same batch, then if you did.

Yep, this one came from pao_revolt and is Batch# 3849B203. I ordered my Xeon yesterday from NewEgg. I was hopping to have it hooked up and ready to go today BUT it shipped from the New Jersey warehouse! Being in SoCal usually everything I order from NewEgg I get the next day. Anyway, I won't get my W3520 until Tuesday.

I got a 920 from him batch 3849A895 that is a worse chip than my 920 C0. This W3520 came from NewEgg, its a 3848A352...

I hope mine performs as well as yours does. It would be cool to run that puppy at 4.4G's@~1.26v on my Classified.

My D0 CPU arrived and I just finished hooking everything up except the HD/CD Drives. I dialed it instantly to 200 bclk and it POSTs just fine. The IOH Temp is Super Hot! It got all the way to 85c and still climbing up! Man oh man...I need a fan to cool it down. What's the highest IOH temp before I start to worry about it? I took some pictures and will post them here as soon as I find my adapter so I can upload the pictures to Photobucket.

Any more additional results with your D0 ... interested to see how these later week B batches are overclocking?

My D0 result with plain watercooling ,Roomtemp 22C ,Turbomode off ,HT enable.

I guess those are pretty good temps for that voltage Venom... what cooling and FPO batch # ?

Finally getting a little better... EVGA Classified, water cooling with the heatkiller block...

Is this on the 3848A352? I just got one with the same batch. I haven't tested it yet as I'm waiting for the motherboard and memory to arrive, but looking at your results it's a good one!

Yes it is, I am going to try some DDR3 2000 in it today and tweak on it some more, I had to run 2.6 divider with the 1600...

Very nice. Are we talking Elpida Hyper memory?

I can't wait to test mine. Some other guys at hw.no got the same batch and they're all looking very good. Glad I went for an Xeon over the 920 D0.

Being a newbie somewhat I am still tweaking to get stable OC state. So I will post back as soon as I am able to obtain one. For now, I'm having stability issue, which may not indicate a bad chip, probably just something I'm not doing correctly.

Where are you at...4GHz + I would hope.

I have the same step as you so I'm really anxious to see how it does....just don't have my board and ram yet.

My Xeon W3520 is the Batch # 3848A352. I run 50nm Elpida Hypers. I am having excellent luck with it. Seems the Uncore is stable up to about 4200MHz or so as well. Very good batch IMO.

You can see my results here!

[road-runner]

I tried the DDR3 2000 its crucial and takes 2v is what it says on it, I have not had any luck with it. I put the DDR-1600 Corsair Dominator back in it and hooked the OCZ Cryo Z to it running it on 2:6 divider. I have only had it going a few minutes but having trouble getting to 230, I guess I need to tweak on it a little more or this may be all she has captain...

[jcniest5]

If I up my PCI-E frequency to 105 or 110, I can get my D0 to POST at 225 blck, but it won't boot any OS. When it finishes POSTing and it tries to go the next step (booting from an OS), the screen just becomes blank, nothing on the screen. I haven't tried anything higher than 225, so I don't know if it would work or not. Gotta give it a shot.

Nice clocks on that W3520 ... 4.8 at 1.28 Vcore

Brrrrr chilly!

Thanks! I'll be running the same batch, the same motherboard and very similar memory (Corsair Dominator GT) with some pretty high-end watercooling... So hopefully I can expect similar results. Monday can't come quickly enough!

Congratulations, very nice CPU Batch?

[road-runner]

Still moving on up slowly, the batch number is a 3848A352 from NewEgg...

Damn, those are some really incredible temps at those settings. What is your watercooling setup?

WOW! Fabulous job, RR!!

WOW! Fabulous job, RR!!

Thanks I have some good cas7 DDR3-2000 on the way so maybe I can get a little better scores...

[mattkosem]

Here's what my D0 is able to do on water with a 21C ambient. Can't seem to get my ram running with the 8x multi at this freq.

As I have promised, here is picture of my mobo mounted inside my new Cooler Master HAF 932 case...

As we can see, there's plenty of room between the mobo and HD mounting housing for those long video cards.

The fact that you can do a prime run at 235.5x21 tells me you have a lot of headroom, especially with better RAM. As I recall, you have a 3845B027, right? Do you find it's vcore setting tops out relatively low? Also, is your val screen with DICE, water, something else?
