Help with AMD overclocking

[gillsman]

I am new to overclocking only 2 days into trying. My computer locks up and freezes during stress testing in prim95. It will show 1 to 5 of my cpu cores stop working them my computer will just stop not shot off just stop or freeze.

My question is what am i doing wrong and why is this happening and how to make stable?

[Computer specs]
CPU: AMD Phenom II x6 1040t 2.7GHz maxed for 40 minutes

Ever though you just cant overclock it

No i have never thought that. I have seen the same CPU overclocked to 3.2GHz stable. I think it should be able to do that at least on my computer.

your cpu voltage is set to auto. you need to manually set it. the reason for the core errors, is they are not getting enough voltage. again raising the vcore will help this.

Looks like too much voltage to me.

i did that and blow up my psu and motherboard so i hade to go get a corsair gs800 psu and a asus m5a97 motherboard to replace it so i am done with the overclocking for now just ordered a AMD FX-8350 Vishera 4000MHz cpu and another videocard so thank you all for the help and goodbuy.

You have to be careful, and dedicate alot of time to achieving a stable overclock. It isn't easy and as you've seen if you don't know what you are doing and start tampering with voltage w/o proper research you will destroy your cpu or more. I have an FX-8350 oc'd to 4.7ghz and it took me 3 days of tweaking, testing and measuring and SLOWLY and cautiously adjusting voltages and other settings before I was stable. Make sure you read all of Tom's stickies on ovcerclocking and do some general research on the web before you start. If you decide to attempt the oc on the FX8350, altho I wouldn't recommend it, it wasn't an easy cpu to oc, compared to other's I've owned.
