I7 4790k OC problem!

[kazhus]

Hello guys!
Was wondering if anyone could help me with my issue with my I7 4790k.
So basically if i'm not wrong at stock it's supposed to run at 4.0Ghz. Recently tried to OC it and came up with the problem that it never goes higher than 2.60Ghz. At least that's what the CPU-Z says and also IETU says the same. Although in bios it shows a differrent picture so i got confused!
the motherboard i'm using is GIGABYTE Z97X-Gaming 3 

Added some pics.

Thanks in advance!

If this is your Idle temps in Bios : 

Then its probs because its throttling straight away, what are you trying to cool it with ? 

Also Jesus Christ your Voltage is high for basic 200mhz overclock

have yu tried running something heavy while the cpuz is opened ? it might just be that the cpu is a idle

No. That's normal temp while in BIOS. 

 

Check Power Management in Windows to see if CPU max allowed power state is set to less than 100%

Try disabling Enhanced Intel SpeedStep Technology, CPU C-States and CFG lock.

Not on mine it isnt lol Never go past 28 ? 

Also for 4.6 thats a HUGE Voltage.

I'm cooling it with some aftermaket radiator dont remember its name though, but its not stock!
ahh the Voltage is that high probably because i have changed some settings there, forgot to set it to defaults before i took a pic.

My 4770k never goes above 75°C at load yet BIOS always reports almost 50°C. Also Gigabyte motherboard.

 

Voltage is fine as well.

No its not for me, I'm on High Power Mode in Power Management.

yeah i did Cinebench, Prime95 and stress test with IETU

Fair enough, personally never seen temps like that in BIOS ever. 

[cj09beira]

then try to see what temps are you getting, with realtemp or hardware monitor 64

whats your temps like when running prime95 ?

max about 82 that is with this voltage as seen in image!

Where do I find the CFG lock?

Personally I hate Gigabytes click bios setup. It's garbage. I use their "classic" mode to enter my values.

 

Your voltage is definitely on the high side to me, I know every chip is different but over 1.35 is 4.9Ghz territory for my chip. About 1.26-28 is the 4.6 average that I've experienced.

 

I have had the exact same problem you're experiencing with my Z87X UD3H, and I resolved it by resetting to defaults and starting over from there in Classic mode.

Not sure how it is on Gigabyte boards, or if its called the same, refer to your manual  Gigabyte might not have CFG lock for all I know

[kazhus]

Oh so i reset the Bios to defaults and disabled the Enhanced Intel SpeedStep Technology.

apparently helped.
Thank you, everyone, for good pieces of advice!
