Memory can i used ddr2 in my pentuim 4 2.0ghz?

pc3200 is original ddr- ram but pc6400 specifies to ddr2. The ram is not compatible. And the key slots on your mainboard will prevent installation.

Hello,

3.80 GHz800 MHz 2 MB pentiam 4

3.60 GHz 800 MHz 2x2 MB for D processer

RAM
1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
8 GB maximum total system memory using DDR2 667 or DDR2 533 DIMMs
4 GB maximum total system memory using DDR2 800 DIMMs
Minimum total system memory: 512 MB
Non-ECC DIMMs

You need to know what socket the processor fits...Is the Intel DG31PR the motherboard you had before? If so, the socket is LGA775. Find a board that is compatible with that socket and the the RAM that you have now...(ie DDR, DDR2, or DDR3) ...any of these listed here should work just fine: http://www.tigerdirect.com/applications/Category/guidedSearch.asp?CatId=13&sel=Detail;31_174_12359_12359

512 MB of DDR2 533 MHz system memory, upgradeable to 2 GB using two soDIMM modules (dual-channel support)

Yes its possible
Yes but the memory its going to run at slow speed 533Mhz

YES, if your motherboard accepts DDR Sdram, and DDR2 Sdram ram memory. If your motherboard has both types of ram memory slots.

BUT, you can ONLY use DDR Sdram, OR, DDR2 Sdram.

You Cannot use both types of ram memory in the motherboard, at the same time.
(BIOS will only recognize one type at a time)


NO, if your motherboard does not have ram slots for both DDR Sdram, and DDR2 Sdram ram memory.

Double Data Rate Sdram ram memory modules, have 184 gold plated contact pins on the bottom.
92 on Each side,

(You can click on the above photo to enlarge)

DDR2 Sdram ram memory modules have 240 contact pins.
120 on Each side.

For installation of windows xp you will need windows xp bootable disk. Set the first boot device to cd/dvd and proceed with installation.

That will work for your computer. There is no problem with that if you are going to add the DDR2-667 into the motherboard together with the DDR2-800 with a different brand name. But you should know this, adding different frequency memory modules will make the motherboard chose the lowest frequency of the two memory modules. In your situation, the memory reading of your computer will be DDR2-667 frequency. The two memory modules frequency should match in order for them to work. DDR2-800 will be downgraded to frequency 667 in order to match your DDR2-667 2GB zion ram.

im not sure but maybe the largest memory that will pentuim 3 can support is 256MB only... hope that i can help...

No, use DDR ram like DDR400.
