i5 750 voltage?
 

Revisiting overclocking my i5, currently 8 hour stable at 200x20, 1.344vcore (rest set to auto) and getting about 75C load temp (prime95 blend) and wanting to see if I can get my temps down any lower well retaining 4 ghz, should I try backing down the vcore more? or is there other voltages I should try and set/reduce?

(Motherboard is a P55-UD4P)

Thanks in advance.

so my 65'c for a 200x20 on 1,31 vcore was not a bad temp.. what kind of cooling solution you have ?

Noctua NH-U12P SE2 with the stock fans on it.

try slowly step by step to go down to 1,30 , my 1,31 was with the auto mode of an Asus board , they are usually generous

It seams to lose stability at 1.30v but is running fine at 1.31, changing the QPI/VTT from anything other then Auto seams to make the system crash, the temperature overall seams to be unchanged for the most part. Could it be I need to remount the HSF? Also I should point out that the ambient temp in the room is 30C, Ambient temp measured in the case (Infrared temp probe) is 42C.

you have a room at 30'c in this time of the year ?... that's explain the difference in temps.

The room hits 30C without the baseboard heaters on just from my two folding systems running. It drops down to about 14-15C with them off.

*EDIT*

I have made another discovery, I removed the side panel from my ATCS840 and the temps on both video cards and the CPU droped by ~10-15C under load. I am wondering if this is because of the stock cooling setup on the ATCS840 (lots of exhaust but little air intake)

try reseating the cooler. I use the same and at 1.32 vcore 200blk I got around 65 max

I am getting 61C on the hottest of the Cores after removing the side panel, should I still try and re-seat the HSF?

on your cooler master ?.......... 61'c is pretty good.. I will work on the ventilation of the case instead, may be you can add a fan at the bottom of the case. and may be somethink like this on the front bay

I use those cage on many of my server and PC. I purchase 30 of them when they was at $ 14
