I'm new to overclocking so clear responses would be appreciated xD

I have an AMD phenom ii x4 and I have overclocked it from 3.0ghz to 3.8ghz (stable) I have tried to get it to 4.0ghz but I bluescreen after about 30 minutes of prime95 blend test. I have the corsair h100 so cooling shouldn't be an issue, also I ran an 8 hour stress test at 3.8ghz and the highest temperate was 40 degrees celcius. so what's the problem here? I tried increasing the cpu voltage a tad but to no avail so what can I do? Any help is appreciated, Thanks

Ok thanks for replying.

My specs:
Motherboard: Asus sabertooth 990fx
CPU: AMD phenom ii x4 960t
RAM: Corsair vengeance 8gb 1600mhz (running at 1333mhz because for some reason my pc doesn't let me run it on 1600mhz)
GPU: Nvidia geforce gtx560 ti
HDD: Western digital caviar blue 1tb
SSD: OCZ vertex 4 64gb
PSU: ocz modxstream pro 600w

Voltages:
CPU/NB voltage: 1.175v
vcore: 1.476v
CPU voltage: 1.476v
NB voltage: 1.096v
NB frequency: 2000mhz

hopefully that helps.

One more question is your 960t unlocked to a 6 core? Should've asked that before but I forgot to.

A bump in vcore could help you stablize 4.0Ghz better, what are your LLC setting currently at and what does the vcore run at under load?

Although you would see more performance raising your N/B up to 2600-2800Mhz over getting 4.0Ghz core clock. To raise the N/B clocks you will usually need a bump in voltage to the cpu-N/B voltage, 1.3v is the max safe for cpu-N/B voltage. I stick closer to about 1.2v cpu-N/B. Warning raising the N/B clocks and subsiquent voltage will increase the cpu and core temps so be prepared.
