Compaq Presario C772TU Laptop RAM issue
Dear,
I have Compaq Presario C772TU Laptop with 1 + 1 Gb RAM . Now I want to upgrade to 2 + 2 (800 FSB ) Gb . When I setup with this ram my laptop not boot. But BIOS shows 4 gb ram. But single 2 gb RAM work well.
What will be the exact solution?

yes I tried 667 MHz 2 gb ram in two slot (total 4 Gb) ==> my laptop restart
800 MHz 2 gb ram in two slot (total 4 gb) ===> machine starts but black screen
but single 800 MHz single 2 gb ram ===> my laptop runs well

667 MHz 2 Gb supports. But I want to upgrade then I face huge problem.
