I have been encountering fps drops from 30+ to 1-2 without any in game reason. For example, in SC2, I'll be looking at my base, at the beginning of the match, and all of a sudden it will lock up, after a few minutes it will go back to normal, though it does come back after a while.
My first assumption was temperature, of either the cpu or gpu, nope, according to core temp I'm not breaking 50C. The next thing I tried was just to lower the graphics settings, even if I change them to low, while the lag is happening, nothing happens. If I begin playing on low, the issue will still occur. My GPU doesn't seem to be hitting too high of a temp as well, maybe 60C max.
One thing that I've noticed, when the lag happens, my cpu usage on all 4 cores hits 100% and sticks there (maybe 95-100%), after a bit the cpu usage goes back to 40-50% and the game returns to normal. Also, with my two 4GB sticks of ram, my memory usage doesn't seem to ever go over 4GB. It'll get to 4GB but not want to go over that. Once the ram usage drops away from that 4GB mark, the game goes back to normal. I suspected a bad stick, so I pulled one out and attempted to boot with one stick in slot 2, wouldn't do anything except turn on the fans. I switched that module over to slot one, booted right up. I still get the lag spikes but now I'm at a loss as to what is going on. I am currently thinking that I either have bad RAM, or a bad motherboard.
I had been toying with overclocking my cpu, I know the motherboard isn't really designed to do that, but I did get it to 2.9 GHz stable in prime95, it just wasn't stable at 3 GHz. I never overheated anything, but I suppose it's still more stressful than stock speeds. Since the problem occurred I put the cpu back to 2.4, reset all settings on the mobo, updated bios, virus and malware checks.
I don't know what else to test/check.
My system:
CPU: Core 2 Quad Q6600 (stock) with Xigmatek Loki cooler
Mobo: MSI G41M-P26
RAM: 8GB DDR3 1066 Kingston
GPU: EVGA GTX 660 OC
PSU: EVGA 600W
HDD: 500GB WD
Windows 7 Pro 64-bit
I apologize for the amount of text, I figured it was better to get it all out there rather than drawn out over several posts.
