The last time I stress test day CPU was when I had the Maximus VII Gene board and the Noctua NH-U12S cooler. And it was with a low ambient temperature as well.
Fast forward to July of 2015 and we have a lot of changes. New case, meaning new motherboard and a new cooler. And Jul means, it's the summer. Sure, we have the A/C on, but the temps are around 26-27C, which is a couple of degrees higher than the previous months.
Wouldn't I have stress tested after all those hardware changes? I should have, but I didn't think it was necessary. For one, the stability of the overclock of Intel CPUs these days don't seem to be affected by the temperature. So the cooler or the lack of airflow inside the case shouldn't have made a difference. Then, Asus says that all of their Z97 Motherboards overclock exactly the same; only the feature set is different. More importantly, I didn't have the time to go through it again.
But yesterday, while I was transcoding a HD video in Handbrake, I got a BSODs. The dreaded "WHEA UNCORRECTABLE ERROR" error.
So the overclock wasn't stable after all. It was time for me to stability test the CPU. At least this time I had a starting point.
“4.5GHz @ 1.21V Vcore with everything else set to default”
That was where the CPU was at up until now.
But first, I wanted to make sure a stress testing tool would find the current overclock settings as unstable. I am not a fan of synthetic stress testing tools such as Prime 95 or AIDA64. Instead, I turned to Asus Realbench, which can be downloaded from here.
