Beginner's Guide to P67 Extreme4

post #1 of 10
Thread Starter 
Just got my Asrock P67 Extreme 4 and was wondering what's a good way to start overclocking it with a 2500k i%

The Turbo OC settings are really nice, pushed mine to 4.2GHz with them.

So I tried the Turbo OC and Day one cpu z was showing 4, 4.2, 4.4
Now it's showing 3.3
Do I have to change anything else manually to keep the board OC'ed?

Make sure it's still set in the BIOS. My board has stayed OCed for about half a month of constant use.

in the bios it says 4.2
in the tweaker utility from Asrock it says 4.2
But windows and cpu z are showing 3.3

Huh. Try setting it to the 4.0GHz Turbo OC and see if CPU-Z sees that as 4.0. Also, make sure you're looking in the bottom-right corner for your clock speeds, not where it says i5-2500K @ 3.30GHz.

I changed it to 4.0 and still shows 3.3, but a strange thing is as the core voltage changes so does the core speed, some times it reads 3991.5 MHz instead of the 1596.7 MHz it's showing most of the time

You have speedstep enabled which dynamically adjust the vcore and speed when needed. Its better that way, you dont want 4ghz while idle, wastes too much electricity.

Then you're at 4.0GHz! Core speed = 3991.5MHz = about 4GHz.

I must have missed that option in the BIOS, that sounds like a great feature to preserve teh processor
