Hi friends

I am using mother board ASROCK N68C-S UCC with DDR2 4GBx2 ram ( Ram which I purchase recently).
When I am using 4gb ram in slot 1 it's working but when I use both 4 gb (Total 8gb ram) ram it boots for first time and I can check in bios that both the ram is detected even in CPU-Z (SPD) i can check that both the slot having 4 gb ram, but after few minutes it get crash and after booting it shows blue screen memory dump and get restarted with no display.

I have checked both the ram it's working in slot 1.

so can anyone help me what's the problem?

Is there any Motherboard memory slot 2 problem? ( I guess that Memory slot 2 is not having problem because whenever I add ram to slot 2 it's recognize first time after that it crash)

Please help me my 1 4gb ram is doing nothing and waste of money.
