I have a 3.2 GHz P4 Desktop, with 800FSB, 1M L2 Cache, and it has hyperthreading technology (whatever that means)
It currently has only 512MB RAM in (2 x 256MB PC3200 DDR Samsung).
This is no way near enough memory for what I need as my PC keeps on crashing.
I'm thinking of getting 4 x 512MB or 2 x 1GB, but I don't know which is better?
Also, what type of RAM do you think I need, would it be PC3200 DDR 400Mhz ?? I don't know what 400MHz stands for!!
Any advice much appreciated
ALSO, I was thinking of upgrading my graphics card, and I don't know if it's possible, because it's an integrated card that came with the PC I bought (off the shelf at PC World).
Is it possible to add a graphics card to a PC, without any soldering or altering my existing PC??????
