Other Memory
DDR2 server memory for older servers comes as ECC modules at PC2-3200, PC2-5300 and PC2-6400 speeds, and the generations before it as DDR-266 (PC2100) modules and PC-133 SDRAM. Order by the full module code on the label of the module you are replacing, speed and letter suffix included, rather than by capacity alone, because the letter separates registered (R), fully buffered (F) and ECC unbuffered (E) modules. Newer generations are under DDR3 Memory and DDR4 Memory, and every type is indexed on the server memory page.

FB-DIMM or DDR2 RDIMM
DDR2 server memory comes in two kinds that do not swap: fully buffered DIMMs (FB-DIMMs) and registered DIMMs. Dell's manuals for two servers of the same era show the split. The Intel-based PowerEdge 2950 takes only 533 MHz or 667 MHz fully buffered DDR2 modules, installed in matched pairs of size, speed and technology, while the AMD Opteron-based PowerEdge 2970 takes 667 MHz registered parity DDR2 modules, with a memory controller in each processor.
| Module type | Buffering | Platform Dell documents | Speeds and limits |
|---|---|---|---|
| DDR2 FB-DIMM | Fully buffered | PowerEdge 2950, Intel Xeon | 533 or 667 MHz; up to 32GB in eight sockets; pairs of identical modules |
| DDR2 RDIMM | Registered, with parity | PowerEdge 2970, AMD Opteron | 667 MHz; up to 64GB with two processors |
Dell's 2950 manual marks single-rank modules 1R and dual-rank modules 2R, the same marks later generations use, so read the type, speed and rank from the label of the module you are replacing. DDR3 servers are covered on DDR3 Memory.
