Help with voltages on an E6600

[LeJimster]

Hi Guys,

I've been trying to fix my friends PC that I built him last summer and I thought I'd try pushing the overclock a bit further as I left everything on stock volts when I built it.

I got his E6600 to 2.8Ghz on 1.35 and it works fine there.

The weird thing is that CPU-Z says the voltage is lower than what I'm setting in the bios, so which should I believe?

I've currently got it sat @ 3.4Ghz on 1.425 volts in the bios and CPU-Z is saying 1.392.

I've read that for longevity you shouldn't push past 1.45 on air.

The motherboard is a Gigabyte P965-DS3.

Dougie...

Can you give me more details on what your running your CPU at? and how long you've had it.

I've just bumped the voltage up again in the bios to 1.43 because everytime i try to run SP2004 the PC would lock up. I'd like to get it to 3.6Ghz, but I don't want the temps to go over 60 degrees load. I'm trying to balance the longevity with stability and performance. I think I might push further if it was my own PC. But it's not .

CPU-Z is now saying 1.408v

Well, I'm using gigabyte's easytune to check and change voltages. I've got a feeling it is vdroop as someone else mentioned.

Current setup is CPU @ 3.4GHz - voltage set to 1.45, actual voltage is 1.42 idle and it fluctuates between 1.41v and 1.39v @ full load. Temps idle are 27-32'C and full load 48-52'C.

I might push it to 3.6GHz but no further.

Thanks for the help guys.

I finally settled at 3.4Ghz with the settings I posted last.. I tried pushing to 3.5Ghz. but the voltage steps were getting larger to get it anywhere near stable at that speed, so I left it at this "cool" voltage. Seems fast enough .
