Help getting to 3.6Ghz

post #1 of 5
Thread Starter 
After having my rig at 3.4GHz for the longest time, I've decided to push for 3.6. Problem is... I can't do it! I've even tried a modest 3.5 and it still won't go.

I've tried setting my RAM timings to Auto, pushing the voltage to 1.28V for both bootup and eventual, increasing VTT but still can't get it. :/

Anyone know where I could be going wrong?

what did you increase your VTT to? I know my i5 750 need 1.3 cpu volts and 1.3 vtt to get to 4.0 ghz stable.

I had it to 1.25 VTT. Think it needs higher? However, I decided to take the CPU to 3.6GHz but instead of having my RAM run at 1800MHz (8:10 w/ auto timings) I put it down to 1433 and it booted fine. So, I think it's my RAM limiting the OC. Corsair says it can run 2000MHz but I don't think it can after this little test. I was even at 1.67v.

You may need it higher. Sometimes people think they have crummy chips when the real problem is the ram, whether that be poor quality ram or just running the ram at speed it wasn't designed to handle. I would set your vtt to 1.3. Believe me, you aren't going to hurt the chip and start playing with your timings until you feed a speed that you are content with and allows the system to remain stable.

It may not be the quality of your RAM that's affecting you. Bandwidths above 1600MHz require much more VTT than when the RAM is downclocked. If you set your CPU to 172x21, you should be able to run your RAM at 1720MHz. While this is not much of a drop, it may ease of your IMC enough to get you stable.
