[behnamagp]

Hi guys

Currently i have 2x2gb geil 1333 memories installed on ga h55m usb3.0 and working fine, but when i want to add new apacer 4gb 1333 memory operation system fails to start and when i use apacer memory alone , system boots, i hear the beep sound then restarts and cant go to bios setting to
Upgraded the bios to f11 version
And using core i3 530 proccessor
Can the cpu cause this?
At one of posts i read that someone solved his problem by changing cpu
He was using h55n mainboard
What can i do?

It's known fact that best working memory configurations (best to worst) are:

1*DIMM
2*DIMM
4*DIMM
3*DIMM

So it's not recommended to use 3 DIMM's. Well, if it works then yes but if not, try 2 sticks. So try that 4GB Apacer with just one GEIL stick and see if it works. Dual channel will not work properly that way however.
