Hello Tom's Hardware users! Thanks for viewing my thread.
Introduction to my problem
4 months ago I built my first PC (specs below). Everything was great, and then I overclocked my CPU. I was very careful, stopping at 4.3GHz @ 1.2v. Suddenly there was stuttering, which was a lot worse when i removed/disabled my GPU. I immediately reset the BIOS/CMOS, and it was still there. I made a post here listing everything that I was trying, with no success. Eventually I RMA the CPU and the stuttering was gone - I presumed this was a CPU problem.
2 weeks ago I decieded to OC the new chip. This time, I made it to 4.7GHz @ 1.3v, and the same stuttering is back. I've tried a few of the obvious things (except a re-install of Windows - I will do this when i have time).
MY PROBLEM
This evening i noticed that the iGPU (Intel HD 4600) is running at 600MHz. This would certainly explain why the desktop is so laggy (literally, text doesn't appear as I type), and why everything stutters. I feel like I have potentially discovered the cause of the stuttering that is driving me insane. Why is it not clocking up?
The stuttering
There is micro-stuttering which is almost like a frame is being lost every few frames. When dragging a window (or turning in a game), it is not smooth. Also, there is periodic stuttering every second or so. It's more profound in Minecraft than it is in Battlefield, which points towards the CPU again. It is present on Youtube (yes, i've tried various browsers), the desktop, software, and games.
What I have tried!
- Updated BIOS,
Please see my old thread if you would like to know what i tried back then:
