i5-750 core Voltage setting problem

G'day all,

I'm wondering, when Intel say the max Vcore for the i5 750 is 1.4V, does that mean I should avoid setting it higher than 1.4, or does that mean I should avoid setting it so high that the BIOS reads greater than 1.4? Because when I set it at 1.4V, when I reboot and go back into the BIOS, it reports it running at 1.376V (or 1.372, I dont remember). Likewise once the computer boots up, CPU-Z reads 1.376 as well and drops a bit under load.

Does this mean I can push it a bit further, or would it be dangerous to set higher than 1.4V in the BIOS even if it reads only 1.376V (fluctuations and stuff I suppose).

It'll run at 4GHz at that voltage, but if I could push the voltage a bit further I'm sure it could reach beyond 4GHz, as the load temperatures are only 66C.

EDIT: Forgot to mention, my board is a Gigabyte P55A-UD3 with a Coolermaster Silent ProM 600W and an ATI 4870 512mb. CPU is running a Megahalems.

It's all relative. It's not like if you go one click higher your CPU is going to explode in six months. I just wouldn't go much further. I'd also watch your VTT (needs to be <1.21V).
 
At the moment my VTT I have about 1.17V from memory, with the ram running at 1.58V. I could probably lower the VTT a bit but I was concerned about people saying not to have it too far from the DRAM voltage. I've tried boosting my DRAM voltage higher, but regardless of how high I set the voltage it wont clock any faster than 1600MHz 9-9-9-24 (which is what it's rated at, and not bad considering I'm running with all 4 ram slots filled for a total of 8gb).

I dont really mind if I shorten the life of the CPU/mobo/ram a little bit, as I do a lot of number crunching which is very time consuming and I'd rather save a few hours a week now and just upgrade sooner, but obviously I dont want to kill off my components in 6 months, lol.
