N68-GS4/USB3 FX Motherboard wont boot

[didis_be]

Hi all,

I have a strange behavior with a N68-GS4/USB3 FX AsRock mobo (NEW !)

I installed a AMD Phenom II x6 1055T Processor CPU 2.8GHz 6MB Hex Core AM3 125W Six Core Hexa and 2 new RAM Corsair CMY16GX3M2A1600C9R Vengeance Pro Series 16GB (2x8GB) DDR3 1600Mhz CL9 XMP.

The system sometimes boot .. sometimes not.

Sometimes, I can boot and have a normal sound (beep) when turn ON.
The the OS is loaded ..

Sometimes, no display, no beep, only the CPU FAN is ON? .. then I turn OFF (press several seconds on power on button) , then turn ON ... wont work, turn OFF, turn ON, turn OFF, turn ON... and after several try .. (3,4,5... depends) then sometimes, it boot normally.


Any idea ???

It stay TURNED on last night without problem ... but .. then, after a normal shut down .. dont turn ON again ...


Regards,

may have to manualy overclock to get the memory at 1600 [ Supported memory: DDR2-1066, DDR3-1333 ] and then in my opinion with 8gb stick maybe too much on the memory controller as well ..

look over at g-skill forums on set up

then you see that board was not tested with anything over 4gb ram??
