RAM: 8gb Corsair vengeance 1600mhz
GPU: Radeon HD 4850, shortly updating to HD 6870
other internals are SSD, HDD and optical drive.
So my question is, with the set up i have above, what is a rough theoretical maximum i could achieve OC'ing the 2500k by just adjusting the multiplier (no voltage adjustments etc) on the stock cooler?
Basically i want to push the CPU as much as i can without having to get into after market cooling and adjusting values in the BIOS which i dont have a full understanding of.
Mine using the Auto OC picked 4.2Ghz, I can run 4.3 with the same settings though. My Vcore hits 1.36 according to HWMonitor with Bios setting on Auto. Max temp I've seen is 65c on one core during BF3 and IBT
You really don't have to change anything other than vcore and multiplier even for a 4.7ghz oc. Aftermarket cooling can be had for $25 and get you to that speed. The stock cooler is pretty horrible, during the summer I had to turn off turbo just to stay in safe temp. The auto oc usually overvolts so I would recommend manually ocing. Stock vcore is 1.2-1.25 turbo which won't get you much more than ~4.0ghz but the issue is going to be temps depending on roomtemp with the stock cooler.
