So long story short, I've had my I5 6600k overclocked for several weeks now to 4.2ghz @1.235vcore. I decided that I wanted to start pushing it a bit more, so I bumped it up to 4.3 and restarted. Everything worked fine, including stress tests. However, for some reason, the programs I use to monitor my temps when stress testing keep freezing. Thinking that it was unstable, I tried opening other programs such as chrome while I had a test running, and they worked fine. Could this be a sign of an unstable overclock, or a problem with the programs themselves? I'm using NZXT Cam and HWMonitor.
