To start, uninstall the overclocking software, permanently. Then read some guides.

Then come back and post your temperatures, voltages, and BIOS settings.

Third, keep in mind this is an ivy bridge chip, not a sandy bridge. If you want high numbers, go sandy; if you want better efficiency, performance, and features, go ivy. (HINT: A 3570k at 4.4 is about equal to a 2500k at 4.8)

hi, my bios settings: manual sets 41 multi.. whit bus 103 and offset on + whit memory at 1600, thats 4.2 GHz and when I change multi.. on 42, 43 or 44 system dont boot, oc error and back to bios, did I should live bus on 100!? and then change multi...

Do offset +80 and try 4.5 or 4.4..if its stable reduce offset to 75 and so on until it gets unstable then incrase +5 and ur grand..got my i5 3570k @4.5 woth offset +55 or +50 cant remember.. Max temp 75 on stress test..dont touch bus speed leave it 100 and just play with multiplier and offset...and disable power saving settings..

Keep your bus at 100 ALSWAYS!

Take out cmos battery and wait 15 mins...(motherboard battery) my was stuck at 38 no matter what...and that solved it

I don't know if you ever solved this problem, but I just want to make a suggestion in response to amateur's suggestion.

Mine was also stuck at 38 no matter what I tried for a while, but rather than take out the CMOS battery, which tends to be a pain and risks damage, I used the CMOS Jumper.

Check your manual for the exact location and procedure, though assuming this is your board I'm pretty sure I see it.



I believe it is the little blue cap at the bottom of the board to the left of the dark blue (USB 2.0 i think) headers and to the right of the white header. I also have an ASUS board and the jumper was much easier than trying to get the battery out.

All you should have to do, assuming that is the jumper, is cut the power to your motherboard (at least turn off the PSU, I usually unplug it from the wall also) and move the little blue cap from pins 1 and 2 to pins 2 and 3, then move it back to the original position and you should be set. Just a reminder that this clears all of your BIOS settings!

Again, refer to your manual to be sure on the exact location and procedure.

After trying the CMOS jumper, which some people have said doesn't solve their problem, removing the battery is worth a try if the problem isn't fixed.

If you don't have a jumper you can also use a peice of metal (non magnetized screw driver for instance) to connect the pins.
