It may be your chip, it also may be some BIOS setting that's hampering your overclock.

Undervolting is cool I just tryed 3.24 ghz at 1.325vcore but it wont run very good it took 1.425 to get it to run aquamark! That could be temps too they were high like 41 idle and 62+c load never let it get hotter. Cant wait to get the 6320 or 6550 chip should be a good overclocker.

Also keep in mind the fact that I've done the vDroop mod, so the values I'm reporting at are very close to the actual voltage under load. If you haven't done a mod (or one doesn't exist for your board), I'd try to see what voltage I've gotten under load, and correspond that to the BIOS setting that gets you the proper voltage under load.

Well, I've done some more testing to see how low I can go on voltages, and my BIOS likes to limit me to VID - .1v, so I can set a low voltage of 1.1875v (1.2875v VID) in the BIOS. Under droop this equates to 1.176v at load, so I guess I'll try and see how far this voltage can go... Here's the results at stock speeds.

I haven't tried more than 3.1GHz, but I got by with 1.250v. It's very cool.

Nice work. I've bookmarked this for later overclocking use.

I will be trying 3.2 again @ a lower vCore this weekend.

i've done similar with AMD CPUs .its really was the way to go with TEC cooled CPUs.

Id like to ask a stupid question cos im running an AMD CPU, but what is the stock load voltage of your CPUs ?

afzsom

It varies from chip to chip, and really from setup to setup. Each chip has a different stock voltage (VID value in CoreTemp), and each board has a different level of vDroop, so its really hard to give a standard load voltage. Given the max VID of 1.35v and the usual .075v droop, I'd say anywhere from 1.24-1.28v under load is normal for stock. Of course if the VID is lower, the load voltage will be lower.

The Pook

1.325v for 3040Mhz on a E2140. Stop yer *****in'.
