Core i7 Overclocking by Batch #

[siyah]

i have a W3570 ES with this of the cpu writing,because i have not the cpu installed.

Q1DV ES Costa Rica
AT80601 000918AB
3835A597

my question is its CO/C1 or DO stepping?

[madmax999]

I think that Xeon's can't be C0/C1 revisions.

Hmm that's an old batch# I thought the Xeons are D0, but that batch seems like a C0 !!!

Could be an early version of the xeons. The only way to check it out is to test it yourself.

Keep us updated

Hi guys

Last question, I have 2 2x2gb kits of the DominatorGT-CMG4GX3M2A2000c8 from my 1156 rig ( got both kits for about the same price as a 3x2gb kit would have cost ), is there any reason I wont be able to use 3 of these stix with the 1366 platform?

Nope, they'll do fine.

Ask the seller for the sSpec Number, if it's SLBEW or not. Or for a CPU-Z screenshot. You can easily get B0 or C0 instead of D0 so I wouldn't take the risk.

when its a BO/CO/C1 whats about the temps and v-core nearly @4,0-4,2ghz

its a big difference to a DO stepping?

[zalbard]

vCore, yeah, definitely. I wouldn't buy anything but a D0 tbh.

Ok, after two days of fine tune:

Xeon W3520 Batch: 3931A356

Maybe i'm able to hit 4.5GHz
Temps 79-85 LinX running.

Nice! Should mean good things for those with 3931A batches.

[tatts]

Early results from my 3847B021

I need to turn the pump and fans up before i push too far

3.9ghz - 1.168V


4.2ghz - 1.264V

That's too much voltage for just 4.4 and on a Xeo....DAMN !

[OC Nub]

Nope, they'll do fine.

Thank you, the savings will allow me to get the Classified.

Amaizing killer chip i7 920 D0 Batch 3849B056 Its AWESOME.......

[DomagojX]

omg..great chip

[zalbard]

Yeah, sick, I need like 1.33 for 4.2 for mine on air... I think I have a crap BIOS, though, so I'll try to go lower when the new one is out.
But doubt it's going to be lower than 1.3 which is crap.
Max temps @ 77C under LinX load, though, so looks like vCore doesn't affect them so much. On the other hand, whenever I go for 4.4 I am pretty screwed.

[H2O]

Wow amazing chip! Where did you find it?

[tatts]

Amaizing killer chip i7 920 D0 Batch 3849B056 Its AWESOME.......

I would like to see more than 4mins of prime, can you run linx or ibt?
I guess this will be on eBay with a stupid price tag very soon?

I wouldn't mind to pay "a stupid price" for that CPU

[Dahaka]

HI!!.

Today i bough a core i7 920 D0 batch #3943A507 and i don't find nothign about this batch or similar to get some references :S.

[tatts]

who would pay £450 for a £200 CPU that isn't even stable??

Good point

This is a good batch I got many units of the same batch doing 4.2ghz HT ON @ 1.225v core, 1.225v vtt primed

that's way too "stupid price" for me...

Hi mate u seem to have some selling skills but i didnt ask you to advertise my chip as ITS NOT FOR SALE!, i like to share my findings with people who are intrested, now if my benchmark / Test result is hurting your eyes i suggest you look away. and talking about stupid prices well, only clever people would have a good estimation!
