It depends on the NorthBridge of the motherboard and the socket of the P4. Most intel-processor supported DDR3 Motherboard should be able to run a pentium, but remember that Pentium4 are very slow and DDR3 is still very immature. I recommend you to rather spend more money upgrading your CPU AND MOBO, rather than moving directly to DDR3.
socket l775 its compatible with it
some game can run on that but not so good.
No you can't
512 ram
All Pentium 4 processors support SSE2.
e2200 would be better as it is newer than the Pentium 4 and is dual core while the Pentium 4 is single it has also been proven the e2200 is better than 2 Pentium 4 put together
Yes though you may not be able to run the game on it's highest settings.
yes it is
Yes, depending on the motherboard. Most Pentium 4 chipsets support up to 4 GB of RAM, although the motherboard may not physically support enough RAM modules.
The RAM of an Intel Pentium 4 processor was as high as 1GB or 2GB. The chips were made between 2000 and 2008 before being replaced by dual core chips.
Although very expensive, 4 GB DDR2 and DDR3 RAM modules can be purchased from many online retailers.
All members of the "Model 15" family are Pentium 4s or based on a Pentium 4 core, so yes.
