Hi Overclockers,

Recently I tried to overclock my cpu but it seems that my cpu running really wild from bottom clock speed to maximum speed. Please take a look to my my screenshoot.

Configuration,

CPU - i7 4790K
GPU - Asus GTX Striker 760 4GB (SLI)
Mobo - Asus Maximus Hero VI
RAM - Kingstone Hyper X Fury 8GB 1866MHZ
SSD - Samsung 120GB 840EV0 x 2(RAID 0)
PSU - Corsair RM1000
CPU Cooler- Corsair H80i

I think there is something wrong with my CPU take a look at the Clock speed before I start bench marking and while doing it.

Thanks.

Intel speed step... u'll get varying speed. Or did you even apply those oc setting? Cpuid shows your multi still at 41x... 1.37v vcore kinda high for 4.6ghz oc. Start around 1.20v for vcore decrease and increase as required.

If oc profile is applied... then most likely your h80 unable to keep up with the heat generated running 4.6g at 1.37v, and you'll get throttled once temp reach 99c. I'm getting 90-98c with corsair h105 @ 4.7ghz/1.21v vcore when doing ibt stress run.

Thanks for the reply but is there any solution? really need help.

go bios, disable eist, c1e and similar power saving function

Control Panel > Power Options > Change Plan Settings > Change Advanced Power Settings > Processor Power Management > Minimum Processing State > Change to 100%.

Heh. Why worried about that? Its just power management feature because If the CPU load is low then the clock will be lowered.

Funny you guys.

Thanks for the reply> FYI I'm still noob sorry for the funny question.

It's not a funny question. Many people don't know that processors these days go on variable speed for "Green" purpose.

If you like to see it at full speed all the time, try the steps mentioned.

Everybody is a noob some times, including me. If you're gonna overclock, see if that thing can waltz with 1.25V vcore at 4.6GHz. If not, don't push it because you just got a second class chip.

Well it is for me since he got one heck of a spec and came asking why the clock went to the zoo. Kid just got a loaded gun to play. I hope he knows the chip max voltage.

Well, nicotine already explained it.

After that TS asked for a 'solution' which I think he's asking how to make it not fluctuate. So that's why after that we post the method to get that.

Getting the clock to be at a fixed speed is the best way to do stability test.

Seems like he's in the right path, judging by the target voltage set. Push the Button!

Sheesh peeps now OC on the fly while we back then have to work our ass in bios.

I still do mine in BIOS. Nothing beats that.

BTW roeybi, I wholeheartedly agree with 1.37v is too high for a vcore @ 4.6GHz. It might bump into dangerous 1.4v during stress test.

Yeah thanks for the advice man.... I did some ibt...damn the temp went to 99.....so I'll do some more adjustment
