Memory Problems DDR3

[halfblood]

Hello, i have a problem with my pc. It has 4GB Ram and i want to take them off and put my new RAM ( Corsair Vengeance LP 8GB DDR3 1600MHz CL9 Dual Channel ) but my pc stucks at Acer Empowering People Black screen. I tried to put one old ram (2GB) and one new (4GB) in dual channel but it doesn't work ( I hear buzz sounds from the pc ). Anyone can help me please? I think i have to do some settings from the bios but i don't know how to do them. Thanks.

is this is your PC its all Acer branded?
Acer Aspire X3900

if yes then your PC only supports Max at 8GB Ram and i am sure thats 2X4GB ram sticks not single 8GB

Yep, Acer Aspire X3900. I know that supports max 8GB Ram. I have 2x4GB but it doesn't work when i put them on the mobo.

Remove the Motherboard battery that will reset the CMOS settings and check if that helps

I tried to do it but it doesn't work.. i think the problem is that my motherboard supports 1330Mhz memory and my new ram has 1600. But if I put an old ram and a new one the 1600Mhz have to downgrade to other one ram frequency.. I really don't know what to do..
