Hi. I have a motherboard ga-970a-ud3p rev 2.0 with a fx 6300 processor and two memory modules hyperx fury 4Gb 1600 mhz cl10. I have experienced several random system freezes and restarts as it is described above. when i run memtest86 four hours, no erros are found. I am not doing any overclock, i tested system stability with aida64 and prime 95 and everything was ok, with the CPU reaching max temperature around 55° C with stock cooler, so i think heat is not the problem. I discovered that putting the memory to work at 1333 mhz the issue becomes less frequent, the computer could run 5 days without problems but it still occurs, playing games, watching youtube or even when i start a program or copying an archive, so i suspect the motherboard, CPU or the memory (even though it passed memtest86 test) is faulty.

What i tried to solve the problem till now:

1- update bios to latest version (FB);
2- manually change memory timings;
3- run memtest86 with each RAM individually and with both for more than 8 hours.

By the way, when i run memtest86, in cpu selection changing the options to round Robin (al cpus) and sequential ( all cpus) can't pass test 2 (adress test, own adress). the system freezes. other options are ok.


Any sugestions? Thanks in advance and apologies for any English erros.
