i5-2500k won't overclock
I first assembled my PC in 2011, but I didn’t often require overclocking until recently. (The only components I’ve changed since then are my GPU and my HDD to an SSD.) I’ve been reading instructions on how to increase the clock speed of my 2500k, but no matter what I try, I’m stuck at around 3.3GHz maximum—specifically, the highest I see is 3292.96MHz according to CPU-Z.
The latest guide I’ve tried is this one, but I’ve also experimented with other resources over the past week without success.
CPU: Intel Core i5-2500K Sandy Bridge Quad-Core 3.3GHz
GPU: EVGA GeForce GTX 1060 3GB
MB: BIOSTAR TZ68A+
RAM: 16 GB (G.SKILL Sniper 2x4GB, Corsair XMS3 2x4GB, both 1333 MHz DDR3)
OS: Windows 10 Home
Edit: I’ve used Prime95 for stress testing, but it still caps at 3.3GHz. I also attempted adjusting the fixed CPU speed, individual cores, and both simultaneously without changing anything.
The Vrm cooling on that board isn't great, but you can still overclock. Go to bios under advanced settings and turn off all power-related features (c1, c2, c3). Enable epu speedstep, disable turbo, and activate internal pll voltage override. Set the rise multiplier to 44 and increase voltage to around 1.3V. For stability testing, run a prime test for about 10 minutes if it crashes—slightly raise the voltage with + key pressed and retry. The maximum is 1.4V, but don't go close. What cooling solution are you using?
