Sandy Bridge 2600K/2500k batch# and overclock thread

Unclewebb = Kevin? How is that a guess for him where that is coming from? Shouldnt he know the cource of the register?

Yep he's the guy.
He reads a register for that voltage and another one for wattage but we guess that they're not real Vcore and CPU power consumption.

"If it ain't broke... fix it until it is. " - Hey, that's my problem sometimes!

Intel provides two registers in the Sandy Bridge CPUs where you can read the VID voltage and the power consumption. VID voltage is not the same as actual voltage. VID voltage is the amount of voltage that the CPU thinks it needs and actual voltage is what you set in the bios less any vdroop. If the voltage is set to AUTO in the bios, CPU-Z actual voltage and RealTemp VID voltage might be very similar.

I also included the data coming from the power consumption register. Based on burebista's testing, I'd have to say that number is not 100% accurate. If Intel is not using actual core voltage to determine power consumption then it won't be accurate. It's too bad Intel has decided to use some sort of VID based approximation for both of these numbers.

If VID and actual core voltage are similar then the power consumption number is probably very accurate. If these two values are different, I don't believe power consumption will be accurate. I asked for some feedback and more testing in a thread here a while ago but no one responded last time I checked.

First posting - 2600k Overclock Numbers.

Ewww, nice Seko, what do you use for cooling?

My cooling

I use a Thermalright Venomous X with push/pull

does push/pull help much? Ive just got 1 fan on my coolermaster 212 plus

It does make a difference. Depends on the case and how many other fans are set up and how they are set up though. Couldn't tell you the difference in temps though. I can run a trial and find out. Of course every case is going to be different.

Well, I've got a mid tower, and only 1 case fan. I don't like all the noise, prefer whisper quiet. You get those temp's running Prime as well? My temps go through the roof.

Everything else in bios is on default overclock seems to be stable i am just wondering did anyone tried oc with offset voltage and if any problems occurred.
After the screen shot i run prime95 small fft for an hour and blend test for few hours and it passed.
