View Full Version : Benchmark to test for CPU errors? Verify that undervolt isn't causing CPU to mess up.

I just undervolted my CPU (Phenom X4 9550) last night. The CPU is undervolted by 0.75 watts.

So far it's been great, my computer is a lot quieter than it normally would be.

However, I know that undervolting too much can result in incorrect results from the CPU, so I'd like to test to see if that is actually happening.

Is there a benchmark to test that? I'm thinking something along the lines of running some big, delicate mathematical calculation and then applying sanity checks to the answer.

Does this exist?

Thanks,
-Max.

I think you misunderstand the possible symptoms of undervolting. If the voltage is too low, the CPUs will turn off as quickly as hitting a light switch turns off a lightbulb. I do not believe undervolting can cause any sort of "subtle" problems.

A script that lowers the voltage in steps demonstrates this nicely... as soon as the voltage goes to the step that is too low, the computer turns off instantly.
