i5 2500k OC with Gigabyte Z68x-UD3H-B3

post #1 of 3
Thread Starter 
Hello,

I'm trying to OC my i5 2500k to 4.5ghz and keep it stable on the Gigabyte Z68x-UD3H-B3 motherboard while keeping the power saving options on the CPU active. I know most OCing guides tell you to disable the power saving tools like Turboboost and Speedstep, but I was wondering if there was a way to OC this CPU while keeping these features.

I was able to achieve a stable 4.5 OC on the i5 2500k while having the power saving tools off, but was unable to do so with them on. Would it be a matter of setting the DVcore to a higher offset, or would I have to give up Speedstep and what not to keep the OC?

I'll link my build below and any help with the matter is greatly appreciated!

- Gigabyte Z68x-UD3H-B3
- Intel i5-2500k
- G.Skill Ripjaws X Series DDR3 1600Mhz C9 1.5V 8GB(4x2)
- Corsair A70 Air Cooler
- Cooler Master Silent Pro 850w PSU.

if you are getting blue screens or you computer is shutting off suddenly while the CPU is NOT under load, then its an issue with the voltage downgrade. turning off EIST and C1 will help fix this. I have Speedstep and Turbo on with a 4.7 overclock.

When I attempt to OC with those settings on, I can't even boot into Windows, it goes to the Welcome screen and then crashes.

Would it be a matter of adjusting the Dvcore or having a different voltage, as I was running it at 1.3v for 4.5 ghz.

It also doesn't help that Gigabyte's Bios is a bit different that other setups, so I can't really follow other people's guides on the topic :S
