Hello, I recently did an overclock for my i5 2500k. I tried to set it initially at 4.5ghz at 1.35v but after 20 minutes of running prime95 at large fft it crashed. I backed off and set it to 4.4ghz at 1.35v and ran prime95 last night for 6 hours and goot no errors. I don't get any crashes when I am browsing the internet nor when I am in any games. My tremperatures are about 40 degrees at idle and around 70 at 100% load. How did I do? I have 750w corsair PSU and a asus p8p67 mobo.
