Overclocking 4770k with water loop

[98Redbird]

Hey guys, I built a new setup a few months ago, and am now adding a second 780 in SLI and also am adding a custom water loop. My question is this, I was able to get 4.6 GHZ at 1.29v, which was the best I could do, keeping it stable. Temps were up in the mid 70's. I'm assuming my temps will drop fairly dramatically with the water loop, so, can I up the voltage? I know that 1.4v is really the absolute limit (I'm assuming for heat purposes), but could I take it to 1.4 or 1.45 as long as temps remain low (70 and below)?

 

What else would I risk by upping the voltage? Or is it just heat which will damage the CPU?

 

The darn thing seems to have slammed head first into a wall once I hit 4.6 Ghz. Takes a crap ton of voltage and won't budge from 4.6. It will boot but not run stability tests. Do the Haswell's become horribly inefficent beyond 4.6?

 

Thanks!

Don't go over 1.4

No, 1.4V is the maximum recommended voltage, regardless of the temperature of the CPU. If you go above that you'll shorten the life span of your processor significantly. There have been Haswell chips that died in matter of weeks, because of too high voltage (above 1.4V).

go to 1.5v for the benches. keep it under 1.4v for normal use.
