Hi guys,
I have started to have some problems with my PC (components described bellow) recently. Sometimes restarted during playing game after I switched to automatic OC done by mainboard. So I started reading a bit about OC and did some adjustments:
Let MB to do OC automatically using Asus EZ setup. Then reduced Turbo from 4200Mhz to 4000 only. Manually changed RAM to 1666 from 1333 done by MB and also set voltage to 1.65V on RAM. That's actually all I have done and everything should be ok. BUT it is not.
OCCT fails - everything seems ok, temperature around 60 and then suddenly temperature goes up to 120 for like 1 second and CPU Voltage to 0 and OCCT ends test.
Prime95 restarted computer (dunno when exactly did it over night)
Memtest 86+ - is ok running like 4 hours with no error
Please do you have any ideas what could be the problem? Should I let MB to switch RAM to 1333 and lower voltage? Or should I try so set Voltage of CPU lower then MB does? (100.33x40 is set to 1.256 in Turbo by MB). Or just give up OC what would be shame because of capability...
My HW:
Mains parts:
MB ASUS P8Z68-V, Intel Z68 – last firmware
CPU Intel Core i5 2500K
RAM Kingston HyperX Genesis Grey 4x4GB DDR3 1600 MHz CL9

Graphic Card Gigabyte GeForce GTX 660 Ti OC, Windforce 3X, 3072 MB DDR5
Case - AeroCool ExtremEngine 3T BBA (Aluminium door)
Cooling:
CPU - Noctua NH-U12P + Noctua NM-I3 Secufirm2
Paste - Noctua NT-H1
Case 1 - Noctua NF-R8 PWM
Case 2 - Noctua NF-R8-1800
SDD+HDD:
SSD 335 Series 240GB, SATA 6Gb/s – updated firmware
1x SEAGATE Barracuda Green 2000GB
1x Western Digital WD30EFRX 3000GB
To show you what is going on please find attached results from the beginninng of Prime95:
