Unstable operating system due to memory

[AFRICANwatepark]

I have pny xlr8 ddr3 8gb memory and an M5A78LM_LX motherboard. the problem is random blue screening heres some info on what ive tried to resolve the issue, ive tried setting the timing values to 9,9,9,27 and the voltage to 1.65v and it makes it boot up and load 1600mhz and 8 gigs of ram under the performance tab on task manager but will still blue screen. if i leave everything alone and on auto it shows up as 600 something mhz speed on 8 gigs of ram and causes blue screen. ive got it to be stable if i leave everything but the d ram timing config on auto and set the d ram timing config to 933 i think. but its only showing 4 gigs whats going on here any help would be great. (update i changed it from 933 to 800 on the dram timing and set every value in manually and it still is showing 667 mhz speed in task manager but its showing all 8 gigs now, i think it will be unstable like this and bluescreen)

Which blue screen is showing up?

boot with memtest86+ from http://www.memtest.org/#downiso (usb autoinstaller)

Which CPU are you using?

In which Dimm slots is the RAM installed?

reset the CMOS/BIOS by jumper

Do you use 2x4GB? Is this a new set of RAM?

memtest was fine?

use bluescreenview to have a look at the logged bluescreens

usually if only 4GB is shown there is a contact problem -> unplug and replug the RAM for about trhree times
or
the RAM is incompatible to the motherboard -> update the BIOS (directly within BIOS)

the native RAM speed of the 8350 is 933MHz (double data rate -> 1866MHz)
