Because this program is actually doing video encodes, the amount of time it takes to complete a loop greatly depends on your CPU. Of course, quick is a relative term depending on your CPU.

But for my final stability test I set it to infinity and then let it run for at least 12 hours. For a quick test I like to use a 5 loop run. X264 Stability Test - It is best to run this test from a HDD you have in the system if possible, not a SSD, because it does write a lot to the disk. The memory stress test is good too if you are overclocking your memory. I run the CPU, FPU, and Cache stress test for at least 12 hours before I consider the CPU Stable. Under the Tools there is a System Stability test. If you want to test your CPU overclock with a few other stability tests I recommend the following:Īida64 - You can just use the Extreme Trial Version, not the free edition. This is actually why a lot of modern motherboards have an AVX offset setting now, that automatically lowers the CPU OC Speed a few notches when AVX workloads are detected. This is because using the AVX instructions not only generate more heat, but they also put more stress on the CPU and tend to reveal instability more. However, Intel Burn Test did use AVX, so Intel Burn Test would often find instability when Prime95 would not. For example, old versions of Prime95(always make sure you have the latest) didn't use the AVX instructions. Just the fact different programs use different instructions sets can reveal instability in the CPU. Because while a CPU might be stable in one program, it might actually be unstable in another. It definitely is a good thing to test CPU overclocks with a few different programs, IMO. The pauses aren't because your CPU is unstable, it is because your CPU is loaded to the point it can't handle doing anything else and gets backed up. This is also why you are seeing odd behavior.

It, AFAIK, has no error detection like a proper stability test. That is why it is called a burner and not a stability test. It is designed to just load the CPU as much as possible to generate as much heat. Furmark's CPU Burner is not a stability test.
