I was going to try. read around some forums. tried 1.32v rebooted and bios hangs, sometimes lets me get to bios settings screen but still hangs before I get chance to change anything. I had to cmos reset before i could get into the bios. maybe a bios bug. using a beta bios. if it was temp problem. it would of shut off,right?
Its going to take more voltage then that to boot. No matter try to use this software GIGABYTE TweakLauncher2 http://www.gigabyte.com/support-downloads/utility.aspx mine cant do 4.9 in vantage or any other cpu loaded app 4.8 is all on a h70 ln2 the thing went 6.0+
Youre gonna need way more voltage, id say start off at 1.4volts.. Roughly the amount mine needs for 4.9
Why you wanna push the limits of your cpu? Its a challange ,its a frustration? WTF dudes,push the limits of all components and voila you have crash after crash. Good luck And btw not all i7 cpus can be put it on high freq.thats why we have Xeon cpus,for quality.not quantity like i7 consummer series.
I have another quastion tho: I can easily get 4.8 from my i5...but in which games I can see the difference in 4.6 vs 4.8...or even vs 5.0? OR the game is not worth the candle?..
For you to perceive difference between 4.6Ghz and 4.8Ghz and 5.0Ghz, you need to make sure you are not limited by GPU. In your case, GPU is the bottleneck IMHO. If you had a GTX 780 SLI setup, then upping CPU clocks from 4.4Ghz to 4.6Ghz would be more perceivable than if you had a GTX 780 single. I was in a similar board and ended up going from 4.6Ghz to 4.8Ghz when I clocked my GTX 780 Ti to 1250Mhz GPU / 7500Mhz VRAM. It did improve performance mildly, but perceivable in CPU-intensive games like BF4 and Watch Dogs. The same goes for higher RAM bandwidth, which can improve minimum FPS dips when CPU is your bottleneck in systems with very strong graphics, like overclocked GTX 780 Ti or SLI GTX 780/Titan/Ti, etc. When GPU is the bottleneck, faster RAM is not likely to improve minimum FPS dips. In your case, I would relax and be content with 4.6Ghz.
you get 4.9 by throwing masses of volts at cpu. personally I've let the idea of de-lidding slip into mind a couple times now.
