My friend has been having issues with drops in performance while playing battlefield 3 and bad company 2. He can normally maintain 60 fps 100% of the time however he has recently been getting drops into the 20's for a few seconds at a time. I don't remember exact temps but CPU and GPU are far below concerning temps. His motherboard has been reaching 100c+ which we believe to be related to the problem. His specs are
FX8320 @ Stock
Alright well you verified everything that I had already told him, I told him a few months ago that he needs to keep an eye on it so he doesnt burn his house down. We also ran across a "fix" which was to disable amd turbo core and that got him down to 83c which is less bad... Ive told him that it would be a good idea to upgrade to a 990fx because he is interested in OCing but I think hes leaning more toward the buying VRM/MOSFET heatsinks.
As far as I recal CPU temps were high 50's, GPU temps were low 60's and the other motherboard temps were in the 60's
That motherboard he has will be AWFUL for overclocking even with heatsinks as the power phases are TERRIBLE. DO NOT expect heatsinks to fix it. The is a badly designed board from a power standpoint. VRMs heatsinks won't fix this.
