In my new build:
fx6300
ga-78lmt-usb3(rev 5.0)
hyperx blu 1600-4gb
cx430v2
zotac gt630 1gb ddr5
320gb samsung hdd

After about 1-2 hrs of usage or in games after a while I get bsod with system service exception.
Should I downclock the ram.Although the ram is supported in the motherboard ram support list online. If so do i have to change timings as well. I am a complete newbie when it comes to overclocking.
Currently I am running on 1066 by manual multiplier in bios with multiplier set to 5.33 and the voltage for ram is set to 1.5v by default. I tried to set it on 1333 with 1.5v but it still gave bsod after an hour of usage.
Any suggeston or possible solution would be really appreciated.

thank you.
 
For a clearer understanding I am posting the settings from bios:

HT Link Freq [auto] 2000Mhz
Memory Clock [x5.33] 1066Mhz
DDR3 Voltage 1.500V
CPU voltage control 1.4250V
CPU NB VID control 1.2150V

DRAM Config
(inside that following settings):

DDR3 Timing items [SPD] [Auto]

CAS# latency 11T 7T
RAS to CAS R/W Delay 11T 7T
Min. RAS Active Time 28T 19T
TwTr Command Delay 6T 4T
