DDR Memory, first embraced by NVidia to open up the bandwidth on their GeForce 256 Video cards, is now rapidly becoming integral in Desktop Computer design. Compared to RDRAM, DDR is relatively inexpensive to produce, has a much better latency profile than RDRAM, and effortlessly provides outstanding bandwidth. With DDR RAM the PCxxx designation refers not to the base memory speed, but to the full theoretical bandwidth of the module DDR has exactly twice the bandwidth of conventional SDRAM, at the same Bus speed; e.g. PC100 SDRAM = 800 MB/s; PC1600 DDRAM = 1600 MB/s This 128MB PC2100 DDRAM chip operates at up to 133MHz bus speed, and has a total theoretical bandwidth of 2100 MB/s 184-pin DIMM Configuration: 32MB x 64 DIMM Type: Unbuffered Error Checking: Non-parity Voltage: 2.5V SDRAM Timings: CL=2.5 Requires a suitable DDR RAM compatible Motherboard & processor combination (see related items sidebar) CMTL Certified Includes System Mechanic Utility to keep your PC running faster, cleaner & error free Free tech support
