Hello Guys.
My Problem is quite simple i can't OC my 2500k. After i changed core multiplier in bios and reboot it doesnt work. CPU is working on normal speed (cpuz shows 3.3GHz alltime but in task manager it shows higher clocks). I tried flash bios and reinstall all drivers from motherboard site but it didnt help. To be sure i watched a few videos of OC on this board and i cant see any thing that i could do wrong. The only thing i found that i found out is that when i start motherboard program Clickbios II I have a error "Please install Intel ME8 driver to enable CPU overclock". After this i reinstaled it few times with few versions but it didn't help (in bios it says that IME version is 8 something) . If you have any idea what i can do with it please help.

Should be able to install IMEI from here, version 9.5.15.1730

Yes, it shows under Windows8.1, but should work with W10.

I'm not sure how/why that would impact your overclocking though.

CPU-Z is showing a static 3.3GHz? Try using something else, like HWMonitor (for example) and see what clocks are reported there?
Or, run something like Cinebench without the OC and then with - compare results. Should be pretty obvious if your OC is taking....


While we're on the topic of overclocking, I'd be a little apprehensive with that PSU.
OCing a 2500K shouldn't make or break it.... but there's very little protections in that unit for overvolting, nor does it have any form of thermal shutdown:

Reinstaled IMEI from your link didn't help much. ;/
Lower one is full default. Works normal but when i changed multiplier static 3.3.
As for PSU I don't plan crazy OC for now i think that geting anything better than stock 2500 is good.

Second pic is default (stock) Bios settings not sure how it went 3.7 on 2 cores. On first i changed few options and set it to 4ghz. Its blocked at 3.3GHz.

It didn't go to 3.7GHz on 2 cores, it went to 3.7GHz across all cores.



Load optimized defaults in the BIOS. Ensure you're starting from a 'stock' position.
If there's any BCLK changes applied etc, that might explain it - a BCLK setting of 112 would be 33 (stock multi) x 112 = 3,696MHz
