184-Pin DDR 400 ECC Unbuffered Module

This Kingston ValueRAM stick delivers 1 GB of DDR 400 memory rated at PC 3200 with CL3 3-3-3 timings. It operates at 2.60 V and includes error-correcting code in an unbuffered layout with a fitted heat spreader. The 184-pin form factor fits legacy server boards that accept DDR SDRAM.

Suitable for legacy server repair, not modern builds

Technicians maintaining older rackmount or tower servers that specify DDR 400 unbuffered ECC memory can use this module for direct replacement or capacity matching. It is not for systems that require registered modules, higher densities, or faster clock rates than those stated above.

184-pin DDR SDRAM interface decides fit

The 184-pin DDR SDRAM interface is the single specification that determines whether this part will install and function in a given server. Verify the motherboard manual calls for unbuffered ECC DDR 400 at 2.60 V before ordering.

Questions about this item

What does DDR 400 (PC 3200) mean for actual throughput in a server?

DDR 400 (PC 3200) indicates a 400 MT/s data rate; the module runs at CL3 3-3-3 timings with a 2.60V supply.

How does the 184-pin DDR interface limit bandwidth in practice?

The 184-pin DDR SDRAM interface operates at DDR 400 speed with CL3 latency, delivering PC 3200 bandwidth for compatible server boards.

Will the heat spreader change the module height for my 1U chassis?

The module includes a heat spreader on the 184-pin DDR SDRAM PCB; verify chassis clearance against the added height.
