FAQ:

Q: Which is the best DDR2 RAM?

A: Best Memory (RAM) G.Skill 2GB PC2-6400 DDR2 DIMM Dual Channel Memory Kit. … CORSAIR XMS2 2GB 800MHZ DDR2 Memory. … Wintec AMPO 2GB 800 MHZ DDR2 Memory. … Kingston ValueRAM 2GB PC2-5300 DDR2 DIMM Memory Kit. … G.SKILL 4GB DDR2 1066 (PC2 8500) F2-8500CL5D-4GBPI-B. … Kingston HyperX 2GB DDR2 1066 (PC2 8500) KHX8500D2/2G. … Crucial 4GB 1066MHZ DDR2 Memory CT2KIT25664AA1067. … More items…

Q: Is PC2 ram the same as DDR2?

A: PC2 is a lower end type of RAM as well, while PC is a higher end type of RAM. That is “basically” correct. DDR2 XXX has been tested more thoroughly than PC XXX and that in turn raises the price not not necessarily the quality.

Q: What is 2GB RAM?

A: The 2 GB limit refers to a physical memory barrier for a process running on a 32-bit operating system, which can only use a maximum of 2 GB of memory. The problem mainly affects 32-bit versions of operating systems like Microsoft Windows and Linux, although some variants of the latter can overcome this barrier.
