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

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.

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???
Batch# ???
@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.Quote:

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!!!!!!
hlo
Has somebody tried a cpu with this batch? 3912A888
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.Quote:

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..Quote:

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.Quote:

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.
Yeap :shakes:Quote:

I would run something that ables you to keep voltage around 1.2-1.3v for daily usage bro. THe extra voltage sometimes is not worth it for just a few MHz.Quote:

http://img29.imageshack.us/img29/6766/superpia.jpg
As for getting 4.4GHz on air, that sounds a little ambitious tbh, I was told by guys on here I would be VERY lucky to get that once I put my chip under water...
blunt
yes your runs are better now, I remember yours were a bit slower too! Super pi is a single threaded bencmark, having more threads will only make it worse. disable two cores, it should get even faster. My Phenoms ran it the quickest on two cores.
Yes, 4.4 Ghz is extremely hard to get stable. You are stressing everything there, the CPU Itself, board everything. most people seem to run about 4.0-4.2GHz stable for everyday use.
That's true, I'm just trying to push till its limit, I'll be happy if I get it OCCT stable @ 4.4Ghz then lower down to 4.2Ghz for daily use. I know at some point it will need lot of juice to beef up the extra Mhz.Quote:

Nice blunt
4.4 on my megahalem here :)
will post some screens soon.
with super PI or something.
I wish I could remember what batch # this CPU is - the box is around here somewhere I'm sure.....
I know I can can actually do it quicker than this but I'm in the middle of doing other things.... Like wise my CPU can clock this high on lower volts but fiddling to try and get 8hr prime stable...

Might good CPU you got there. Why don't you run the below version of Super pi, it has tenths added to the time. So the time is more exact instead of just 7 sec, 8 sec, etc.Quote:

momoto,you sir have one awesome cpu there.
very very nice indeed:shocked:
OMG those D0 are overclockable as hell !!!
with my C0 I was able to only reach 36xx MHz with Air and voltage of 1.35v !
I replaced it yesterday with a D0 and reached 3800 with 1.23v !! :eek:
Today I'll try 4GHz with my cooler master V8 and see if it needs a slight bump in voltage!
I'll keep you updated regarding this Batch# 3923A367
And I really need to get a water cooling system !! :yepp:
Welcome to the elite club of the D0 i7's :welcome: :ROTF:Quote:

Wish I was as lucky as you Patty, mine went to 4.0 and it's pretty much stuck there, not a good batch :(
I think I'm done :D 4.6Ghz is my max, can't break the 220BCLK wall :(. 4.2Ghz@1.39V OCCT stable ain't bad I guess, I think I could lower a little bit more since 1.39V is my first start to run OCCT.

By the way, I would love to get a water cooling system soon, may you please state your equipments?
Thank you for radaja
It puts it again for Salamndar
My CPU was able to turn Prime 95 for nine hours or more

Will you go out the great result when "PCI-E(102)" and "CPU Clock Skew" and "IOH Clock Skew" are reviewed ???
:eek: Do I see 4.0 GHz with voltage of 1.13 in windows !!!!
Nice chip you got there, but I think the temps are too high at that voltage.
Hmm, I'm able to complete 2 hours of OCCT with 1.26v @ 4.0GB, does QPI PPL and QPI/DDR voltage have that effect on core temperature?
you wanna post your main settings? Maybe we can try and help you out :)Quote:

imo, thats a nice OC for air cooling. The Prolimatech Megahalem was the heatsink I was thinking about. Can you tell me a little more about how you have your voltages setup? Is 4.5Ghz your 24/7 OC and what temps do you get?
Wrote batch number down at home, forgot to bring it to work :doh:
I will also get some screenshots when I get home.
Specs are below, not bad with a stock cooler!!
Trying to decide if I want to screw with water again or just go with a good air cooling setup. I have a MCP-600 and MCP-650 pump, a Dangerden and Weapon heater core both with shrouds and about 10 Sanyo Denki San Ace fans (all from my old setup). I just bought a Apogee GTZ but have yet to even open it.
Tried 185X21 with 1.2125vcore and 1.25625 vcore and it errors out on LinX in about 30minutes. Kept other voltages below the same. Probably getting too hot!!!:D
Any suggestions?
Thanks,
Ed
I have one question. I have the Core i7 920 D0 CPU, but the thing is that Core 1 (in CoreTemp) is always 10°C hotter than other 3 cores.
At low heat levels the difference is smaller, but when the heat is reaching 84°C on other cores, Core 1 is jumping up at 94°C.
Is this CPU good for RMA or they won't accept it for RMA just becaue of this? It's annoying because Core 1 is constantly heating way too much where other cores are still withing acceptable levels.
Well I posted about this chip a few months ago and after a few more months of messing around with this thing here is what I have finally settled on.
(For now! :rofl:)
Batch #3910A372 @ 4.25GHZ
CPU Voltage - 1.3500
QPI Voltage - 1.3750
CPU PLL Voltage - 1.82
IOH Voltage - 1.16
Rest is in the sig.

Thankfully the e-tailer agreed to give me a replacement, now I have a nice chip!
1.800v is the default setting for CPU PLL on a UD5, however, I run mine at 1.300v, as I read somewhere that lowering this voltage can sometimes help with stability.Quote:

Damn nice voltages mate, are you using CPU/IOH clock skew, if so what values do you have them set to?Quote:

No mate, that wasn't a typo, I'm running 1.300v CPU PLL, and my boards default is 1.800v, I read on EVGA forums that lowering this setting can actually help with stability, so I started playing around with it to get my 4.2GHz o/c stable, and I got it right down to 1.300v, when it was at 1.800v my overclock was unstable, now it is perfectly stable.Quote:

Its on water, Heatkiller and 120.3 . Getting next cpu though, this one is no goodQuote:

It's is all about finding your chips sweet spots, I'm not 100% sure, but I think that some chips like to have specific distances between Vcore and Vtt, some like wider distances, while others prefer them to be closer together.
I've had 4 of these chips, and my first 2 seemed to like the distance between Vcore and Vtt to be closer than the 2 chips I have here atm.
@oggie, have you just got your CPU in your loop, or do you also have your GPU(s)?
CPU is in one loop, gpu and NB in other ;)

Why are you running Linx with only 1624MB if you have 6GB RAM? Click on the "all" button and check your stability again please, I doubt it will be stable with only this vcore.
Just redid my voltages a bit :)

4.2 HT on
EDIT: here it is
http://i30.tinypic.com/9uqlxt.jpg
You guys are lucky with that voltages. Is LinX as good as Prime95 or OCCT for stability testing? My first attempt at 4.2Ghz @1.4V and I can only back down to 1.39 in order to be OCCT stable.
Btw, imo, I think your temps are a bit high @ that voltage since this is mine @1.4V
