What is single rank memory (regarding DDR2 Ram)?

Have got 2 PC3200 512Mb SINGLE RANK memory modules.





I want to add this to my current config. of PC4200 512Mb * 2. Can Single Rank memory be used with a dual channel set up...realise that the different speeds won't be an issue (other than I'll be restricted to the speed of the PC3200 modules) but am wondering where/how does single rank apply; if at all





Tnx!

What is single rank memory (regarding DDR2 Ram)?
Single Rank Memory defines a set of DRAM chips (on a module) comprising 8 byte wide (64 bits) data, or 9 bytes (72 bits) with ECC. All devices in a Rank are connected by a single Chip-Select. The actual memory size is not defined. Single-sided memory modules are always Single-Rank. Double-sided unbuffered DIMMS and SODIMMS are always Dual-Rank. Server DIMMS may have up to 4 ranks. Single-rank memory modules will allow a server to reach its maximum memory capacity and highest performance levels, whilst enabling support forthe latest server chipset and motherboard features
