Core i7 920 steppings
- Thread starter Compddd
- Start date
Sorry, I read more and found out there is only C0 steping, made myself look like a noob 🙂
What is the difference between a Core i7 920 with the batch number 3836B043 and 3839A577
Do different batches overclock better than others? I see a lot of people with A batch 920s that overclock to 4.0 GHz, should I take mine back and try and get a A batch one?
My goal is to hit 4.0 GHz, I'm using 2000MHz DDR3 OCZ memory as well

4Ghz on air?
Holy crap dude why waist a ton of cash buying DDR3 2000??
You will get to 4.0Ghz with a good after market cooler and some DDR3 1333-1600 which is much cheaper.
Save your self some mega bucks and use that cash to uprage to a new Video Card to sli with your current GTX 280 for that new system..
Really guy I have got my cpu up to 4.2Ghz with my ram and I have seen others get 4.5-6 its just the luck of the draw.

compddd - you should be able to get it through most batches, some OC better than others. Just try to get your base clock above ~195 if you want 4Ghz.

4Ghz on air? at what load temps?
Using a Noctua and a True both were about the same results at 4Ghz 38c at start up and about 48-50c after a couple of hours of compression or video conversion or some gaming Crysis,Bioshock,NFS UnderCover,FarCry 2, and Spore..
I know those temp are kinda high but I am not bitching since I am running 4Ghz 24/7

i have an A0... but its not a 920. 😛
ummm id like to see a screen shot with 10x as your multi, you can keep the fsb 333.
i have a Q9650 ES and its multi sir is not unlocked. Unlocked multi is 50x my friend like the QX series.
A0 are NEVER and i repeat NEVER FOR SALE.
These are properties of INTEL, and were given to major vendors and distributors. These chips are NOT ment for consumers.
They also offer NO TECH support or Warrenty on these chips.
Wish I could still give a screen shot but I sold that cpu some time ago to upgrade to the new system in my sig 😛
Actually I wish I would have kept that cpu it was a hell of an overclocker.
Anyways you say you have a ES version of the q9650 and you dont have unlocked multi's??
Then you have a review version that Intel sends out to tech sites such as A/T but I had a in house version and they do indeed have all unlocked multi's..
Your version and mine are 2 completely different cpu's..
If you are interested you can research it via google..

There's also a lot of FUD going on with regards to overclocking, people claiming low temps @ 4.2 or running 4.0 on the stock cooler are just full of it. Real temps under load are going to be in the 80C range at that speed, which is why HardOCP was disabling Hyperthreading just to get 4.0 stable without insane temps and that's with a TRUE.
Truth is 4.0ghz is around all you are going to get on air, sure you might get it to post and run Pi at 4.2 or above but that doesn't mean anything. I've yet to see a motherboard that will perform consistently well above the 200-205 BLCK range, so getting above that is a real challenge aside from the temps.
Some more BIOS revisions might change that however, but for now, I think 4.0 is pretty damn good.

I never ever stated I got to or over 4ghz stable with a stock cooler shit if that was the case I would be able to cook tonights dinner on that sucker.
Nope I and many others are sitting pretty at 4ghz using an after market cooler such as a True or Noctua 1366...
I'm not saying I havent tried 4ghz on stock cooling though but thats why I got an after market cooler..
I am also using 2 120mm fans in push pull config at full speed when most people set there fan speed to thermal control.
You can beleive me or not I really dont care I dont have to prove myself to you or anyone else.
The op asked for some opinions and thats what I gave..

I wasn't calling you out so don't be so defensive. IN fact, my post had nothing to do with yours, I was merely commenting on a hell of a lot of crap being posted here and elsewhere about what one should expect with respect to OC'ing the 920.
I was merely trying to set some realistic expectations for the OP, OTHER PEOPLE who claim to be stable at 4.2+ on air because they can run SuperPi and 3dmark are just full of shit.

OOOMMMGG RaptureMe really 4Ghz on air is great at that temp...
i am on a Ultra 120 and the cooler simple can not cope with the extra heat at 4ghz given out by the i7 920 thats why i was thinking 3.6Ghz is the best speed to be at 24/7.

4GHZ on air + craptasic Nvidia Chipsets.
E0's can do it on air, you just need good ambients and a good sink.

Power of Water on Linkpack. (look at max reported temps on realtemp)

Someone about to get aigo'd soon. 😛
Sorry dont mean to be so defensive just stating the facts.
Yeah I totaly agree with you though not everyone is going to get the same overclock as me and mostly its luck of the draw.
But from the many posts I have seen and read alot of people are getting the same results as me with using the same type of cooling.
As for stress testing so far I have used Prime,Cinbench,all the future marks/Pc marks,and a few verious others..
I totally admit though when hammered and maxed out when stressing I do get higher temps much higher like 70-75c.
But this is only in those stress testing programs.
I can max out all the cores for hours on end using video editing programs,Compression,Converting, or run several games at once and never see temps ever get that high.
Still though you guys say 50-55c is good but that seems abit high to me and 70-75c is just nuts.
If I ever seen my system hit temps that high in everyday use I would not clock to these speeds..
