Simmtec, Inc 512MB DDR400 PC3200 CL3 184-pin DIMM desktop RAM

512 MB DDR400 desktop memory module

This 184-pin DIMM provides 512 MB of DDR400 memory rated at PC3200 with a CAS latency of CL3. It uses sixteen 32x8 chips in a dual-rank 2Rx8 layout and operates at 2.5 V. The unbuffered, non-ECC design suits standard desktop motherboards that accept DDR400 DIMMs.

Capacity and headroom for legacy systems

The single module adds 512 MB of addressable memory, which is sufficient for period-correct operating systems and everyday office applications. Dual-rank organisation helps fill a memory channel efficiently on compatible platforms. The 512 MB limit means the module cannot support modern workloads, large datasets or multitasking scenarios that require several gigabytes of RAM. Builders needing higher total memory must populate additional slots with matching DDR400 modules.
