Help me overclock my i7 3770k

post #1 of 11

Thread Starter 
just built my first pc, used to buy pc's from dell, decided to try this out with an intention to OC.

heres my build.

intel i7 3770k
asus sabertooth z77 mobo
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133
Mushkin Enhanced Chronos 240GB SSD
CORSAIR H80 (CWCH80) High Performance Liquid CPU Cooler
Corsair TX750W PSU
EVGA GTX 680
2 hdd's, sound card, Rosewill BLACKHAWK Gaming ATX Mid Tower Computer Case, etc...

i tried overclocking it, got it to 4.6ghz, but once i put a little stress, im talking installing programs, the temps went up to 80c, than i went back down to 4.22 and now the temps normally dont go over 50-60c.

since the cpu is so new theres not much info out there on overclocking it compared to my q6600 that i went from.

any help would greatly be appreciated.

i think being around 4.5-4.6ghz stable would be more than enough for me.

thanks in advance. smile.gif

Also, don't install programs until you are certain that your OC is stable. It will cause file corruption and could leave you will a lot of problems down the road.

do i need to set a constant Vcore to maintain such a low temp ? because with intelburn test i get as high as 95 with liquid cooling system

Intel Burn Test is going to make your Ivy processor run hot. It's not just you its all of the chips. Think of a stress test as a worse case scenario, it'll run hotter than under normal conditions. Water won't keep temps in check with Ivy bridge. There is a threshold where if you push too many volts you won't be able to control temps unless your using LN2 or possibly remove the IHS and reapply TIM.

For the rest of us on Air and closed water loops even custom water loops, temps are going to hold you back from very high OC's 4.8 <=

If your an average user of computers (play games, do work etc.) I'm willing to bet that for day to day operations you won't notice the difference between 4.5Ghz and 4.8.

well i use H60 as cooling system so i am on the closed water loop side and i did fixed my voltage to 1.250vcore for 4.5Ghz on 3770K and my highest temperature was 83C using prime95

That sounds about right, I have a custom water loop and 2 RADs and I think I hit 80c in Intel burn test and high 70's in prime @4.5Ghz, I was having problems with my OC so I'm back to 4.2Ghz right now until I try again. Temps are always gonna be an issue with this cpu, so don't worry about that, the cpu just can't handle the same volts as sandy

In my experience, you should try and shoot for the lowest voltage that is stable on your Ivy. You could try lowering the voltage just slightly maybe .005v at a time and see if your stable to try and get the best temps. thumb.gif

Hmm I've got a similar setup custom water and x2 240mm swiftec rads at 4.5 during prime it doesn't go past 66c and that's after about a 2hour run. Just curious as to the voltages you were using.
