Hey everyone! I built my PC about a month ago and after a few weeks I decided to overclock the processor. I got it stable to 4.4Ghz at 1.3V I think. When I managed to get hold of some thermal paste, some thermal compound remover and purifier and some wipes, I removed the current thermal paste on my CPU and replaced it. I also opened up my GPU and replaced the thermal paste on that too as the GPU has been previously used in a mining rig and I didn't like the temps all that much. Anyway, I booted onto desktop, temps were much better getting 20'c idle (before was 30-40'c) and 50-60'c load (before was 60-70'c) and the GPU was the best improvement getting 50-60'c at full load on 25% fan speed (before was 70-90'c at 75-90% fan speed). After running a few games to test out the temperatures, I decided to overclock a little further.
In the BIOS I first tried to 4.8Ghz at 1.4V. Of course, it didn't work so I put up the voltage further and further until I didn't like how high it was (1.45V, I kept getting WHEA_uncorrectable_error and machine_check_exception error). So I reduced the clock speed to 4.6Ghz (1.4V) and booted to desktop. I didn't get any errors and games ran fine up to a point where my computer would again display machine_check_exception error and restart. I then put back the clock to 4.5GHz (1.4V) and that seemed stable all until now. I could run games fine and accepted that my CPU could only OC to 4.5, which is a massive overclock anyway so I wasn't complaining.
Now when I try to compress a video I rendered out last night in Handbrake (video is 1080p, 60fps, 50KBS) it will probably get to 25% done and I will then get the error machine_check_exception. Is it because my voltage is too high? My temps are above as stated. My PC has been on for a few days now, do you think that is why? It's stable in all things except handbrake it seems. I would've thought rendering would've been more intensive. Thanks for the help as I have done a little research and found that these can be hard to diagnose. Pretty sure it's not a problem with my GPU, motherboard, HDD, temps or RAM. My motherboard has an on board troubleshooter where it will turn on a light situated at the point where there's a problem with that certain component.
Any help is much appreciated!
