[P4PC]

I'm not exactly sure if this is the right place, Anyhow I'm thinking of buy a graphic card for my Pentium 4 "pci only" found but it's a pci but requirements are Express-compliant system power supply; available PCI Express 2.0 slot. is it mistaken or something what' the drifferent bewteen PCI 2.0 slot and PCI express 2.0 slot. full specs.

Computer: inter(r) pentium(r) 4 cpu 2.8GH Z 280GHZ, 504 MB of RAM (i got two sticks both 256 shouldn't i have 512?) This is the direct link to the graphic card

This are the graphic card specs:

"(i got two sticks both 256 shouldn't i have 512?)"...

Your motherboard is taking some memory for the on-board video. What is your motherboards model number? The "new" PCI video card should work though. Remember to disable the on-board video before you install the new video card. It wouldn't hurt to bump the memory to 1GB

Well, the nvidia geforce 8400gs requires a pci-express 1.0 slot.
Since u have p4,i assume it may have a pci slot. So ur 8400gs is not going to work. A pci-e card is not backward compatible with with pci.but a pci-e 2.0 card is backward compatible with pci-e 1.0
i recently installed a 9500gt pci-e 2.0 in my pci-e 1.0 slot

idk its a HP Compaq d220 Microtower Desktop PC

 

[P4PC]

its old one only got white PCI

 

[T77]

even i am confused.if ur 8400gs is a pci one,how can it ask for a pci-e slot?
ur card should work if u r sure it has pci.
there may be something wrong with the packaging.

 

[talex7]

i think its pci

 

[P4PC]

Yeah man, I'll buy it and see what happens perhaps the discription is just incorrect wouldn't make since at all being two of the same i assumed pci costs more because it's for pci and pci e cheaper because theres lots of models of graphic cards for pci e. I found this and should work for me. if not i will be returning it. Thank you guys for the help i appreceate it alot. i'll let you guys know how it goes
