Im a bit wary of using uGuru for temp readings, its always about 10c less than CoreTemp :/
Im currently struggling keeping my system stable at higher clocks, would seem to be a problem with the bios from what i've read elsewhere.
I can have my E4300 at 3ghz without having to push any more volt thru the vCore or the MCH but soon as i start to go above 333FSB i seem to hit a wall :/
I dont think i will see much of an improvement with the extra couple 100Mhz's though.
But it would still be nice to get it to boot at 3.6ghz, will leave it a while though and wait till i get another cooler or go to water cooling.
