Overclocked 3570k, question about stability using Prime95

First let me mention that this is my first time overclocking.

Anyways, I've got my i5 3570k up to 4.4 ghz, testing stability with aida64 every time I brought the CPU up to a higher speed. After I got the CPU to 4.4ghz I ran aida64 for an hour, but I noticed my CPU usage dropped to 0% two or three times on my task manager, though aida64 said there was never a drop. So I was curious if that meant some errors were happening, so I downloaded Prime95 since I learned that tells you about errors as they occur.

I started Prime95's blend test, and all seemed well so I went to bed. After I woke up, I noticed that Prime95 crashed (note: the program crashed, not my computer). And judging from the "result.txt", it crashed after an hour. Does that mean there's a stability issue, or did the program just bug out?

edit: My temps never got too high, either. From core 0 to 3: 64C, 70C, 68C, 65C, according to CPUID HWMonitor

did it give a rounding error? that means it needs more volts, but if it went for an hour, it's probably good for day to day usage, but not 24/7 loads

Thats what it sounds like. Was this all cores or just 1 core?

If you don't mind your programs crashing and games crashing randomly I'm sure it's fine. Other wise I suggest you address the problem.

What voltage are you at?

Right now, I am at 1.27 volts for a very stable 4.5ghz

I have my ram pushed a little, but not far above the factory clock, whenever I push it, I immediately lose stability. I haven't pushed passed 4.5, and won't until winter here in Arizona. I ran prime95 overnight, and the hottest it got was 79C
