Uniwarking Posted November 20, 2011 Posted November 20, 2011 Hello all. I'm looking for advice on my overclock.

Boinker Posted November 21, 2011 Posted November 21, 2011 Is it stable to 4.50 ghz or are you having issues?? If it is stable then start moving the multiplier up one at a time and running prime 95 blend for an hour. Repeat that proceedure until you are unstable. When unstable try tickling the voltage up a notch or two and rerun the stability test. If not try setting it up again. If that does not work give the vcc voltages an adjust or the PLl slightly up. Just don't get too carried away with the pll. That chip does not like to much of that. Share this post Link to post Share on other sites More sharing options...

Just don't get too carried away with the pll. That chip does not like to much of that. My system is stable in Prime95 for 12+ hour runs at it's current state. I'm currently using a hyper 212+ and getting as hot as 75c on those long Prime blend runs... I plan to upgrade my cooler (not quite sure what yet, thinking the Corsair H100) before I go too much further. I previously had the multi at 46 with 1.35 vcore and I started running into trouble in Prime after a few hours (one core would fail). I have not run at 46 since I bumped my VCCIO voltage from 1.1v to 1.125v... may try that again (1.1v was recommended for 4GB of RAM in a youtube guide and I'm running 8GB of RAM).

Boinker Posted November 22, 2011 Posted November 22, 2011 Just remember as you up the clock speed all of the chip will need help to keep up. Keep in mind that guide will help you along with an upgrade to cooling. The sooner you get it the better as it seems the i7 2000 series chips tend to overclock at best while lower then 70c. Though that's a tough temp to hit on Even full custom liquid cooling the h100 will help you get there. Good luck and cheers. Lets see some benches and stability tests at 5ghz.

Brutality Posted November 22, 2011 Posted November 22, 2011 1.1v was recommended for 4GB of RAM in a youtube guide and I'm running 8GB of RAM uhm the AMOUNT of memory has nothing to say regarding VCCIO voltage.. the SPEED of the memory has.. for example I am running 2133MHz memory and that requires a VCCIO voltage of 1.12-1.14 At 1333MHz it should be 1.05v I don't know for 1600MHz but probably somewhere in between Share this post Link to post Share on other sites More sharing options...

I've just got it set to auto right now, working like a champ. I just need to find a better cooler. My Hyper 212+ makes some really annoying vibrations/noises when speeding up and running at high... going to return it and get something else.

LuckyDeath Posted November 23, 2011 Posted November 23, 2011 See my sig, I've done some OC'ing with your setup. One tip I can give you is to test stability with more than Prime 95. Use OCCT (1 hr test), and LinX (Intel Burn Test) for at least an hour. This will also give you good temperature tests to ensure your cooling is sufficient. Otherwise, the OC is pretty straightforward. Up your multiplier until you can't go any higher (errors or crashes), then up your voltage a bit. Keep upping the voltage till you don't get errors or crashes. Then up the multiplier again. When you get to the point where your temperatures are too high, you can't up your voltage any higher. That means you are limited to whatever multiplier that is stable at that voltage. Pretty much the ceiling on your OC. I was able to get mine to 4.9 GHz, but after that the voltage required to push further were causing unsustainable temps. I keep it at 4.5 GHz now.
