Overclock - checking error?

I vaguely recall one video where Wendell has mentioned that overclocked CPUs should run this whatever software/procedure to check errors, since despite overclocking looks successful and passes stress tests, they could still be throwing out errors that ultimately hinders performance of the system overall.

I just cant figure out which video he mentioned this and I do not recall the exact details.

Can someone help me figure out what this software/procedure is?

Or did I hear something wrong, and I dont have to worry about such "mysterious errors" as long as I pass stress tests?

Meh, if you're worried about overclocking then just touch the multiplier and leave the voltages and base clock alone.

Paging @wendell ;)

Try Prime95. http://www.mersenne.org/download/

Maybe this was even the one Wendell talked about.

Edit: There is also Cinebech.

I have overclocked my CPU a while ago, and I passed stress tests, both mentioned and not mentioned here.

Overclock is stable, at least from what I can see.

I was just asking since I happened to recall Wendell mentioning something that is not used often by overclockers because most settle with passing stress test as a successful overclock. Also, from what I can recall, some overclocks, despite clock speed is maintained and it is not crashing the rig, will constantly report micro errors that will hurt performance.

As I said, it is just something I am recalling off of random memory. So it may not be true.

So, at least from what I can deduce from the two replies to this topic, passing stress test = successful overclock? And I do not have to worry about it?

Asus Realbench I think, it does photo/video work and then all of them at the same time. its not quite as stressful as prime95, but it puts a load on the entire system instead of just the cpu. it uses open source stuffs like blender/gimp/luxmark for the testing.

Sure, also I doubt you'd encounter any noticeable "miroerrors" unless you were putting the CPU under load at all times of the day.
