  • DDR400 speed rated at PC3200 bandwidth
  • CL3 CAS latency for responsive data access
  • 184-pin DIMM fits standard desktop memory slots

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.

Questions about this item

Will this 184-pin DDR400 DIMM run at CL3 alongside my existing PC3200 modules?

The module is specified at CAS Latency CL3 and 2.5V, matching the standard PC3200 DDR400 timing. If your current sticks are also CL3 at 2.5V the BIOS should keep all modules at that latency.

How can I verify the stick is detected as a 512MB dual-rank module after installation?

Boot into the BIOS or run CPU-Z; the memory tab should show 512MB total capacity, 184-pin DIMM form factor and 2Rx8 organisation confirming the dual-rank layout.
