Hello all,
I recently built my first system and done my first overclock after much research. I am slightly concerned about the temperature my i5 750 at 3.8GHz reaches during Prime.
My system is:
I5 750 at 3.8GHz
CoolerMaster V8
Artic Silver 5
4GB G-Skill Trident 1600MHz CAS8
Asus P7P55D EVO
Corsair TX 650W
1Tb Samsung F3
Asus EAH5850 @ 890/1190 1.5V
After 1 and a half hours of Prime i reached 72/73/67/72 .. and then got an error, so i have more work to do
For a relatively medium overclock with an aftermarket cpu cooler, and with all the intake/exhaust fans in the Antec1200, a 120mm Akasa Viper blowing air onto the V8 and low voltages i am concerned that the temperatures do not reflect all the thermal control.
I got temps in the range of high 70's earlier in the week and then quickly set about fixing the inside of the case by re-routing wires, moving the Viper fan to a better location and also reapplying some more AS5 to the CPU, this has brought the temp down a few degrees but i was expecting better results.
Screeni of the settings after 1.5 hours prime:
I would also like to list the main BIOS settings i am currently running on in the hope you can help me optimize them.

Any help with the BIOS and settings is greatly appreciated, though i would add i would like to remain at 3.8GHz or drop to 3.6GHz.
Thanks alot for taking time to read this
