Overclocking a I5 2500k
Overclocking a I5 2500k
Alright guys, I am calling for you help overclocking my i5 2500k. I just changed my PSU and want to see if I can do another overclock for my chip. Last time I had it at 4.4ghz with 1.35v and I believe that it was stable, but I think I can get some more performance out of it. I am currently running stock and have a 212 evo as a cooler. Could you guys help?
No? Only you have the answer. It's not complicated – you already understand what to do. Adjust the multiplier and voltage until you achieve a steady and quicker result.
Your reasoning about why the PSU might assist is unclear; an overclocked CPU shouldn't exceed around 200W – it depends on base TDP, OC speed, and OC voltage squared divided by the product of base speed and base voltage squared. With a 4.4GHz clock on a 3.3GHz core part and a TDP rating of 95W (likely not reaching that at stock), you're already at 126W. Adding a bit more voltage brings it to about 160W max TDP.
At that level, you're likely hitting the limits of your cooler's capacity rather than focusing on stable voltage draw. Still, pushing to 45x100 at 1.38V is definitely worth a try.

At that level, you'd likely hit cooling limits more than anything else.
Still, I thought it might help to try 45x100 at 1.38V, just give it a shot tomorrow.
Wait. You changed your PSU and now you want to try and get more out with the same hardware? That's probably not going to happen. While better PSUs can deliver cleaner power, there's more emphasis on the motherboard and CPU.
I misread your post. I thought this was a first time overclocking question. Joe said all that really needs to be said. Here's a link to a OC guide. Don't focus on the hardware differences.
