1GB DDR 400 ECC Registered module

This 1GB DDR 400 (PC 3200) module uses 184-pin SDRAM with CL3 3-3-3 timing and registered ECC buffering. It is built for legacy servers and workstations that require registered memory with error correction at 2.60V.

Thermals and power in normal use

The stick has no heat spreader and relies on chassis airflow for cooling. Registered ECC modules of this generation typically draw modest power at 2.60V and run silently without active cooling.

What the registered ECC design changes

Registered buffering reduces electrical load on the memory controller, allowing larger populations of modules per channel. ECC circuitry detects and corrects single-bit errors, improving data integrity for server workloads.

Questions about this item

How do I install the 184-pin DDR SDRAM module and which alignment step is often missed?

Align the notch on the module with the key in the 184-pin DDR slot, press straight down until both retention clips snap closed, and verify the registered module is seated in a slot that supports registered memory.

What maintenance or replacement will the 1GB ECC registered module need over time?

The module has no heat spreader and operates at 2.60V, so keep server airflow clean to prevent dust buildup; replace only if memory errors appear or a capacity upgrade is required.

What limit appears first when the DDR 400 CL3 memory runs under sustained load?

The CL3 timing at DDR 400 (PC 3200) sets the latency floor, and the 2.60V operating voltage defines the thermal ceiling during continuous operation.
