OC Sabertooth z77 with I7 2600k

post #1 of 9
Thread Starter 
Hi Im pretty much new to everything here and I just built my second pc.

Thermaltake level 10 gt (black)

Corsair atx1200

SLI EVGA GTX680's

Corsair H100

Corsair Vengence 8gb 1866c9 1.5v

Samsung 830 SSD (256gb)

I7 2600k

Asus Sabertooth z77 motherboard

Windows 7 Ultimate 64bit

And I am sorry about asking this but I am so lost trying to overclock this MB. Is there someone here that has successfully OC'D this board with this processor and can just give a template to look at or copy for my bios. All I have seen out there are videos on how to use the OS side software and when I set it up in my bios it says that the overclock failed. Im new to asus and I thought I'd give it a try because I've always been an EVGA user. On my previous build I had an evga ftw3 with an i7 950 oc'd to 4.4ghz with an H70 24/7 stable:). So what i'd like is another high clock but 24/7 stable. They say you can get to 4.8 to 5 stable and that would be AWESOME!

Thankyou so much for reading this.

Hey mate, here are some screenshots of my BIOS hoping to give you a good start.

Although, this is not the 4.8GHz you wanted, it should give you some good guidelines of what you have to do t get your desired speed.

You can also google "overclocking with UEFI" and you'll get some good gudes and explanations of how to move around the UEFI.

Dude you're awesome but when I go into manual mode out of xmp my ram clocks down to 1333 and when I go to change the speed it it doesnt give me the actual ram clock speed (1866) it sold be at. But thank you so much and maybe someone else will post a higher clock for both of us:)

When you set AI Overclock tuner on Manual the memory frequency button should become active. Click on it and select the freq you want from the pop up menu.

Then go to DRAM Timing control and enter the timings you have/want.

To achieve a higher OC just increase the multiplier one digit at a time until your pc either BSOD or just hangs. Then increase the VCore one step at the time (but i personally would not go over 1.35v for 24/7) until Windows boots. Run some stress tests and keep increasing the VCore until you find stable. Wash, rinse and repeat until you are happy.

No one can give you precise settings simply because for the most part they depend on your CPU. smile.gif

Ok so according to my specs in the bios it should be 4.5ghz @ 1.228 with the blck @ 100, but in cpuz its showing Im @ 1600.mhz with a multiplier of 16?! What setting do I need to use to apply my OC settings in the bios?

That's because it throttles down. Run prime95 and you will see it increase

Yeah found that out LOL, I feel stupid. biggrin.gif

You guys have been awesome!applaud.gif

Ok so right now Im at 4.8 with a vcore of 1.415:devil:. My temps so far idle at 34-35 and my TJ max is 64 according to real temp.thumb.gif

so I guess my next step is to prime95 it then try to see if I reach the 5GHZ summit, unless you have better test I can try? Also my ram is running at 1600 right now but when I try to get it to run at 1866 my pc wont even boot. Whats the deal with that?
