i have narrowed down to this two rams.....
part name->KHX6400D2/2GDescription->DDR2-800, Non-ECC, Unbuffered DIMM Capacity->2GB Timing->5-5-5-15 Voltage->1.85V

and
part name->KHX6400D2LLK2/2GNDescription->DDR2-800 , Non-ECC, Unbuffered DIMM, NVIDIA Memory SLI Capacity->2GB Kit

DDR 2 as it is the latest. But make sure that your motherboard is compatible with DDR2 RAM. If your previous RAM was DDR then I suggest u put the same.

DDR3 is out in market , check the compatiblity in your system.

DDR3 SDRAM is an improvement over its predecessor, DDR2 SDRAM, and the two are not compatible. The primary benefit of DDR3 is the ability to transfer at twice the data rate of DDR2 (I/O at 8× the data rate of the memory cells it contains), thus enabling higher bus rates and higher peak rates than earlier memory technologies. In addition, the DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes.

Thank you for providing information about DDR 3 i was finding it from a long back and i Google it also but didn't got perfect which you had given above.
