Please, I had ASUS P5PL2 Mother-Board, with Pent.4 CPU 2.8 / 1 mb cash,
it have 4 slots for RAMs, DDR2 SDRAM , it works fine with 1 mb RAM
(2x 512 mb PC2-4200 DDR2)
I upgrade to (2x 512 mb PC2-5300 DDR2 ) it works Fine, When I upgrade
to (4x 512 mb PC2-5300 DDR2) which means 2 GB Ram, The Computer did not
startup , even the Monitor is black, only the LED power is on.
When I remove (2x 512 mb PC2-5300 DDR2) Left only 2 rams which are 1 GB,
it works fine, SO, What is the problem here ???? Any Help Please welcome.
My Opreting system is Win XP Media center.

try using 1 stick of the 2 that made it not work.and if it starts up for both then it might be somthing else.

Hi and welcome to PCHF!

1) Did you hear any beeping when the computer was starting up?
If so, the RAM probably wasn't seated correctly.

2) Where you using any type of dual settings in the BIOS?
It may be not properly configured.

If anyone else has any comments or ideas, please feel free to bud in.

Thanks,
Adam
