Amazing Temperature 66C at 4GHz !

How the hell are your volts that low?

He has a nice chip obviously...

That is some excellent results bulldog, I hope my replacement i920 is a goodun.. my last chip was a bit of a dog for o/cing tbh... I needed 1.264v for 4GHz...

Out of curiousity which batch is this processor?

My last chip was 3851A228..

Bulldog has put a sterling amount of persistence and effort into his computer, the results are deserved.

I'll pass on how his volts are that low, could be a good chip, could be something else. Mine seems to have a vid of 1.0625 which I doubt is exceptional, so could well be that his is 0.9V or so at stock

Yep, this is correct. I put alots of hard work to get it stable after 7 hours fiddle with it and finally found my three other setting in bois with lower vcore and got it stable. It not just vcore as I had to use other setting too.

How to find out my batch number ?
 
Written on the box it came in. Software might tell you, but not sure. Mines 3913b213

Google found nothing when I bought it, but now throws up a guy called Beast who's running it at 4.5ghz, 1.425V. Hardly conclusive, but does make me more eager to get it under water soon

I had manage to get 4Ghz with H50 at the lowest temperature at just 65C at bios setting of vcore at 1.16v (1.136v at windows) and got it stable for 8 hours.



I had throw away my cpu processor box (how silly of me) but does anyone know how to find out batch number by running third party software ?
 
You can also find your batch number on the IHS as well... It is the last line of text on the IHS... as far as I am aware there is no software available that can tell you your batch number..

::edit::

What software are you using for monitoring temps?

I saw a thread earlier where someone was testing with the Asus software, CoreTemp and RealTemp, and there was something like a 10c difference between RealTemp and CoreTemp.. apparently CoreTemp reads the temps from the core, whereas RealTemp and Asus own software reads from another sensor, and they don't give accurate readings...

At least this is what someone had said on the thread I am referring to...

::edit::

Silly me, I see RealTemp in the screenshot above... have you tried using CoreTemp?

Its more likely to be the tjmax issue. The number which is used to calibrate the reading, giving you something meaningful in centigrade. Tends to be some argument over which number to use. I think bulldog is using 95, a lot of people on here will be using a larger value. However bulldog did phone intel to find out what this is, there's a thread on here about it
 
So are you saying that these temps bulldog is getting are incorrect?

They do seem extremely low imo, but I had assumed this was just because of the low voltages his chip requires for these frequencies?
 
Just left an interesting conversation with Intel technical support. Essentially they said that tjmax and the like is not considered a means of measuring temperature, and we should go on bios. Ill get a screenshot up

Maybe it wasn't his thread after all then. Or I've just my numbers mixed up. tjmax isn't a percentage though, I think it's meant to be the temperature the processor shuts down at. Still, I think that conversation with intel deserves a thread

I told them many times, that intel say always use bios cpu temperature or gigabyte easytune6 temperature monitor. But, mine never went over 45C on cpu temperature even if I set tjmax 100% and core temp read at 75C and I set tjmax down to 95% and temp was 70C but the cpu temp was read at 43C !!

So, I trust intel of follow your cpu temperature not to go above 67.9C !! (not the core temp reading)

I had now set myself a new record of the most amazing lowest temperature I ever seen in my life with lower my vcore a one drop below and change a few setting in bios. I had ran linux and IBT all success overnight and again ran prime95 for 2 hours with 4GHz with all cores, all threads with HT enabled with Turbo mode enabled with extreme performance enabled with a crazy vcore set at 1.168v to 1.17v with amazing temperature of just below 70C !!! Look at motherboard drop to 30C, North Bridge drop to 40C, CPU temp drop to 43C and the push pull fans still on low speed of 1350/1342 RPM with all fans at the Antec 1200 case set to LOW speed. I playing some gaming and still stable !!!
I had also replaced two fans of Akasa Apache IP54 with superb s-flow with a push pull on the cpu cooler.
Here is the photo of 4GHz with 70C with aircooled pc with HT enabled 4 cores/8 threads.

What are the bios settings you are using, That is 5c lower temps than mine on roughly the same system, although i'm using 200x20.
 
Kept your CPU temperature at bios or easytune6 below 67.9C and you're be fine. Ingorne all core temp such as 85C, 85C, 85C, 85C etc as your real true cpu core will read at 56C if using 85C on all cores temp.

so you're finding the Prolimatech Megahalems is the better performer, I ask because I'm debating to buy a H50.

Both are very good but I choose H50 better because of amazing lower temp plus more roomy inside the case ! So I can fit my side panel fan on my antec 1200 to cool down my graphic card. There is nothing wrong with Prolimatech Megahalems because I cannot fit the fan on the side panel because of this cpu cooler was huge inside.
