[korialz]

My current specs are :
xp sp3
Pentium dual-core CPU e5200 @ 2.50GHz,2.0GB RAM, NVIDIA GeForce 9500 GT
(i know its a bit outdated , this pc was bought 2008-2009)
(if you need more info to help me just let me know thanks)
(ps: the graphics is already upgraded cuz the older one got busted)

I want to upgrade my ram, How can I do it? like can I just buy a ram and install it? (my pc has 4 slots (1 used 3 free but not sure about this, this is just based on a scanner software I used to know my specs).
thanks

What you need to know is the motherboard/chipset on the motherboard (i.e. Intel P55). Without knowing that you can't know what the maximum memory it will support is. If you are running XP Sp3 32bit then the OS can only address just under 4GB of memory so unless you also upgrade to a 64bit OS at the same time you won't get any benefit from putting more than one other 2GB memory stick in. I'd think you'd need DDR2 ram in a system of that age.

this is what I got from crucial.com/systemscanner
Memory:
Maximum Memory: 4096GB
Currently Installed Memory: 2GB
Total Memory Slots: 4
Available Memory Slots: 3
DDR PC2-6400 (whats this? is this my current RAM? ehehehe sorry its obvious I know only little about these things)


System Manufacturer: INTELR
System Model: AWRDACPI
Motherboard Manufacturer: N.A.
Motherboard Model: X31_ICH7

so what now?

damn....what will I do if my motherboard is not branded? because I downloaded another scanner(EVEREST home edition) and it cant locate the manufacturer and model of my motherboard. the motherboard name and chipset are unknown.

Buy another single stick of 2GB DDR2 6400.

Should be able to run it in dual channel mode if you leave the ram settings in the BIOS set to auto.
