Obviously the difference is speed.
Physical size of the memory card. Mobile sdram is smaller than sdram for desktops.
1 GB. Note that there is no such thing as dual channel memory, although computer stores may sell it as that. The dual channel feature is a function of the memory controller. You need two matching memory modules in order for dual channel to work.
Dram and Sdram are two different types of memory.
The main difference between Synchronous random access memory, SDRAM and Dynamic Random Access Memory, DRAM is that SDRAM is synchronous while DRAM is asynchronous. As such, SDRAM is efficient in retrieving and storing data than DRAM.
http://en.wikipedia.org/wiki/DDRAM http://en.wikipedia.org/wiki/SDRAM It explains everything.
2 dimm 2gb RAM comes with 2 1gb modules. 4 dimm 2gb RAM comes with 4 512mb modules.
It's the same thing, Synchronous Dynamic RAM (SDRAM) is typically just a different name for DRAM.
speed?maybe.but more likely the spelling.."DDR2" has no"SDRAM PC2 133 168pin" unlike the"DDR2 SDRAM PC2 133 168pin"It's really hard to see it at a first glance..
The 3GB ram has one more GB than the 2GB RAM. From a user's point of view, that's 33.33 per cent more.
about 42 farts
Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color-coded on the motherboard.
