So today I was rendering a test video, and while I was doing this I was met with a crash, so I stressed tested to see if I was unstable with AIDA and Intel stress test, and both were fine. So I downclocked back to 4.7ghz and tested the render again and it rendered fine.. So my question is, why would rendering kill my overclock but stress testing doesnt.

yes the difference between 4.7 and 4.8 will not really be something you will notice. and you don't want to be 3 hours in to a 8 or 10 hour render and come back to a crashed computer and have to start over just my 2 cents.

Passing AIDA or any other stress test does not guarantee you are stable. This is why a lot of people use multiple stress testing programs as well as real world applications. Sony Vegas stressed your cpu in a way AIDA didn't and found your instability.

Any tips to get my 4.8 back to being stable? I was at 1.350 when it crashed and I don't feel safe upping it anymore, my 4.7 runs fine at 1.290
