Core i7 Overclocking by Batch #

[hlonipha]

it's been awhile since I stopped by. Good clocks guys. what sup chicken?????

What's up bro, thanks for the comment. I got myself a D0 bro . Whats up with you how you been? How's the rig doing? Any changes since last time you posted up?

@hlonpiha, what do you have all of your voltages set to for 4.43GHz in your sig?

I'm putting my chip under water in a couple of week's and I would like to get my chip at 4.4GHz stable.

I'm fairly confident that it will do it, as I have verified my chip with CPUZ at 4.7GHz, but I would like to see what kinda voltages other people are using for these kind of clocks.

::edit::

My highest O/C yet with my current 920!





I got it up to 222 Bclk in the BIOS, and then used SetFSB to knock it up a little further for this o/c.

ouch nice chip you have there

thats on water or air or phase???

@BLunTSmoKeR:
check the table in the first post here.
It gives you a good stepping and primestable oc info.

the voltages on my classy board are way different than the ones I used on the UD5 (I ran an UD5 for awhile before my classy board) once home later I will post them for you but I'm positive that my settings will not bring any help to you with the UD5.
Not to discurage you but in my experience a max clocks validation in not way relates to what we call stable clocks(8hrs prime run). your required volts for 4.2 are fairly high comparing to what mines are. (1.25v) but to keep mine fully stable as you can see I had to bring my volts to 1.42v@4.43ghz ht on.
The generated heat is massive at those clocks full load after the 4-5 hrs. and I have a very good WC setup.

good luck in your clocking!!!!!!

Has somebody tried a cpu with this batch? 3912A888

[Salamndar]

I've ordered a new 920 D0 to replace my 920 C0.
the D0 Batch# is 3923A367, any one tried those?
Should install it later next week !

Hi mate, I fully understand that max clocks validation doesn't relate to max stable clocks, I just figured if I can get 4.2GHz stable under air, I should be able to get 4.4GHz stable once I have it under water.

My loop will be really good as well, I just need to get my heatkiller 3 copper and that will be me ready to start building it..

Batch# ???

Air cooling atm, batch number 3921A624, I have two chips with this batch number, and they are both fairly decent chips imo.. way better than my last 2..

My first i920 D0 was 3851A224, it was not bad, and then my 2nd one was 3910A551 and was faulty, so I sent it back and got my current chip, and also bought another at the same time, that's how I landed with 2 from the same batch.

you'd be surprised, even if you add voltages, it might just not happen. Thats a heck of a clock and not many, hardly any can actually get that clock stable 24/7. but good luck my friend! Keep us posted.

[DavyBoy]

I'll be sure to keep you guys posted, I will be happy with 4.2GHz, but I will definitely be pushing for 4.4GHz!

nice clock! is this with HT on/off?

we all strive for more, but 4.2 GHz seems more achievable for daily use. Good luck though man

how stable is that, nice voltage for that speed

Just enough for cpuz and Internet Browsing

would've been nice if it was 100% stable

look in the lower right corner 8 threads with 4 cores thus HT is ON

I agree mate, 4.2GHz is plenty, but it's fun trying to push for more!!

I'm already running at 4.2GHz stable, though the jump in Vcore and QPI is quite a lot from my 4GHz o/c.

I have backed down to 4GHz for now until I get my loop setup, then I will go back to using my 4.2GHz profile again, the temps should be more acceptable at 4.2 under water, as they were hitting 88c on my hottest core when running LinX.

Though I noticed when I was playing the new Wolfenstein last night, on my G15 performance monitor, the CPU usage was only sitting at 6%, barely using the CPU at all.

Powerful CPU ain't it

Just got my i7 920 last week (Batch # 3912B168) and just play around with it for a bit. I got it up to 4.2Ghz OCCT Stable then I shot it at 4.5Ghz to run Super PI, will see if I can reach 4.7Ghz. My goal is aiming to 4.4Ghz stable on air as well.

[Chicken Patty]

disable HT for some nice improvements in SUper pi

Thanks, I'll keep that in mind.
