Can You Use Ddr2 In Ddr Slot

  1. Can You Use Ddr2 In Ddr Slot Machines
OK! I am a noob at this!
I am running XP Pro 32-bit. I want to replace the Video Card. Nothing great or expensive...just a decent one. It for a friend (senior, that is why XP). I just got him a Dell Vostro 200 slim, added a 1TB HD and installed all drivers and XP. Please let me know 3 things:
1. Does ddr2 or ddr3 matter on the video card..is one better to run on XP
2. 64-bit or 32-bit. I assume 64 will run on 32-bit XP
3. Any suggestions on the card or where to buy (PCI Express 2.0X16)
Thanks! Ynot

Can You Use Ddr2 In Ddr Slot Machines

The answer lies in the question itself. The RAM in each type is the type that will fit and work DDR2 RAM will fit DDR2 Slot DDR3 will fit DDR3 slot and so on. But in each type they should match the speed of the motherboard / processor. No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are. Due to the different pin design of DDR2 and DDR3, it will be physically impossible to put a DDR2 stick into a DDR3 slot. You will need to have DDR3 RAM. When you buy it, be sure that it runs at 1.65V or less; that's RAM designed for the X58 and P55 chipsets. Anything over running in the 1.7-1.9V range was for Nvidia's 780i chipset. You can use (2) 512 MB memory modules in total. If intending to use DDR400/PC3200 make sure it is CL 3. If intending to use DDR333/PC2700, CL 2.5 appears to be acceptable.
