i7 3770k overclocking help needed

post #1 of 13
Thread Starter 
Hello, I am in need of some help. This is my first time overclocking and I have an i7 3770k and an asus z77 sabertooth mobo. I can pass the 15 minute test with 4.7GHz @ 1.25V. When I bump it up to 4.8GHz I failed so I have been bumping up the vcore, but all I am getting are memory related blue screens. I am not overclocking my memory, just setting it to the tested values of 10-11-10-30-2 @1866MHz. The errors I get are either prime95 stops responding or I get a lot of 0x0C5 blue screens and other blue screens not on the list supplied.

Thanks in advance.

Just finished the 12 hour stability test and its running at 4.7ghz at 1.26V. The hottest core his 82C during the test but they all settle around 60-65C.

I would like to get higher than 4.7Ghz but i do not know how to mess with setting with ram to make it so i do not get blue screens at 4.8ghz

What Bsod code is it?

Also post your bios settings.thumb.gif

Im very familiar with OCing on the saber i think i can help.

80-85c is max you should let your cpu go to while overclocking you might be at your limit, but if its only 60-65C as you say you have more oc headroom.

You cannot raise OC with 80c temps. This is fail. If your CPU were 30c cooler..I would venture to say you have headroom for more OC.

That's a nice low vcore of 1.26 for 4.7 GHz. I think you have room to go up in vcore and may very well be able to get to 4.8 stable, but only if you improve your cooling substantially.

If you're keeping your current cooling set-up then I'd run it right where you have it. thumb.gif

I have a fully custom water cooling loop with an xspx rx480 radiator. Only 1 core hits 82 and it was very breifly during the 12 hour test. The rest of the tike it never went over 70C. I will post my bios when i get the chance.

Here are my bios settings, I have it set to offset voltage to save power now that I have stable 4.7, but when i was on manual, it was 1.26V to get stable 4.7.








Also I am using corsair vengeance 4 x 8gb 1866 mhz ram, but I removed 2 sticks because windows home premium only uses 16gb ram.

0x0C5 that one is most frequent, but there is a bunch of different ones that happen too.
