RAM + ALL THE OTHER APPLICATIONS, CAN U ACCESS VISTA OR NOT? AS IN ACCESS THE PROGRAMS IN IT ETC
I have Vista Ultimate 64 bit and it shows all 4 gig DDR2.Running great to.
And PC expert this is a new build so I bought the member has had time to install anything other than the OS.
I would sugest as AW said just put 2 sticks in the yellow slots.Remove the other 2 for now.
Is all the
RAM showing in BIOS/Post screen?Is memory remapping enabled in BIOS?Although I am not sure on memory mapping.
Have you updated the BIOS?
