Core i7 920 rev D0 stepping 5 :)

[tekjunkie]

My DO(s):


i7 920(3845B027) on the classified


Dual channel as one of the sticks died.

Xeon W3520(3844A704) on DFI UT eh8



I am currently working on my W3540 on the classified.So far things look good(fingers crossed) with my cl7 doms on it. It seems to work with exactly the same settings on the classified as my 920,except for the vdimm now @ 1.65.This was all on air as I am planning to water some time next month.

BTW, who says 4GHZ uncore is tough on air

[co2r]

out of this 2 D0s, which one should I keep?

3849A832
3844A934

Haven't started my i7 build yet, but I am thinking of pairing this with

mobo: undecided, but probably the UD4P or a bloodrage (dang pretty)
cooling: air, not sure on this one yet, but I can get a hand on the Xigmatek DK for reasonable price (my budget here is $50 max)
RAM: got a deal on the corsair xms3 (8-8-8-24) ==> good??
~~ i think those 3 parts are the ones important for OC capability, I can list out the rest if necessary

target: OC of ~3.9-4.2

3849A832 seems to be almost on par with the 3845B027 as far I have seen. For example this thread @ the evga forums.

Keep the A832

[INFRNL]

What are the final words from the guys that have the B028's and B203's? I have the option to buy both, but the B028 is a slightly higher premium, wondering if its worth it, or do these 2 batches fair about the same? I need to chech the Denver MC as well to see what they have.

Thanks

If you can only afford one, take the B028, it runs at the same frequency with less voltage. If you can afford two, get both. Both OCs the same, but the B028 just does it with a little voltage than the others, that's all. YMMV, so don't bite me if yours happens to be a little than mine. I'm quite happy with either actually.

[INFRNL]

Thanks, tough call I guess, but seems that less voltage for the same clock would be more beneficial, since I would be running WCG and F @ H on the system. If I could hit 4-4.2 ghz with no more than 1.3v; I would be happy. My Co's from my little experience only hit 3.8@ 1.3v.

Just found a 3849A832; would this be slightly better than the B028 or B203? Someone above said that the A832 would be equivilent to the B027 which is a great chip to have from what Ive read.

Or better yet; which batch would be of best interest? Thanks

EDIT:Would a xeon w3520 be a better option? not even sure if they are supported my my mobos yet; BloodRage, Biostar Tpower, Gigabyte UD4P

Preference in order: Xeon, A832, B028 then B203.

[bluehaze]

A832 is a good batch they all seem to do the same, I can do (Prime Stable) 4.5ghz HT on 4.6 ht off and 4.2 HT on with 2000mhz mem 7-7-7-20. It can go higher than this if you can keep the temps under control.

[INFRNL]

Thanks guys; Just have to think if the Xeon is worth the additional cost. I can get the A832 for approx. $265 or the Xeon for $295. I have heard that the xeons may create issues on some mobos. also I do not know if I metioned it already, but I stopped by MC today when I was in Denver (normally 65-70 mi trip from where I live, but was visiting family) and they had NO D0's at all.

I have found a couple members that are selling D0's and on ebay. Found the xenon on ebay too from platinumicro, but not sure of the batch.

I have seen killer results with the xeon, especially with dice or ln2, but I will only be on TRUE or eventually H2o. Damn decisions, or can wait for MC to get D0's in and get one for $215-250 depending on wether or not they have another $200 deal, lol

[MiKA7]

Does anyone have any experience with batch 3849A772?? only seen this result so far but it looks promising: http://www.xtremesystems.org/forums/...d.php?t=224581

[jcniest5]

Wow...interest dies down a lot since last week or so.

I wouldn't mind getting my hands on either a Xeon or that A832 at all. Both should be equal in OCing and the D0 might even pull ahead a little from the many benches users are EVGA's forum reported.

Of course the 3845B027 batch isn't that bad....

The 5187 Mhz screen shot is included to document the -7C temperature, Vcore was 1.389.

Grats! 5237 MHz is a brilliant OC.

[roller11]

thanks!

[jcniest5]

I'm trying to rekindle the love we once shared...please keep it going, shall we?

[jcniest5]

Okay, so lately has anybody been able to get any earlier batches (3845/3846) from Micro Center? Trend tends to indicate that earlier batches OC better than latter batches. Haven't checked any 920 lately at MC, so I'm not sure what kind of batches they have now comparing to a week ago or earlier.

[Astratuner]

Does my Asus P6T Deluxe needs any bios update or will it just work out of the box these new D0's?

what are your other voltages,btw your temps wasnt -7C thats just the lowest e-leet goes

[roller11]

Right, I didn't realize that when I posted, this was right after my first ever sub-zero run. On that topic, I've found a temp meter, but still haven't found a suitable probe for it, one that goes down to Dry Ice sublimation point (-78C). Anyone know of a source that is relatively cheap?

The other volatges are 1.325 Vtt, and pretty much everything in green in BIOS. My take is that voltage other than Vcore doesn't make much difference with this chip.

Hi peeps another batch check. Iv been offered a 3850A795 920 D0 retail at a pretty good price 2nd hand. The owner has got it up to 4.3Ghz with 1.36v on a Biostar Tpower and air cooling. I can get a new one OEM for alittle more but not sure on batch. As im going watercooling, can i expect that a newer D0 should clock further or should i just grab this one now? I have a UD5.

Cheers Brad.

It should work right out of the box.

[Brad8988]

Well found a 3849A769 D0 going at hardly anymore so went with that as the only result i have found was at nearly 4.5Ghz with 1.38v HT on stable. Hopefully mine will perform close to that.

Hi brad..... how long before you have it up and running?
