Server DDR2 ECC Registered Kit

This 16 GB kit contains four 4 GB DDR2-667 registered ECC DIMMs built for the listed Supermicro X7DCA and X7DCL server boards. Each module runs at 1.8 V with CL5 5-5-5 timing and uses a 2Rx4 organisation on 240-pin connectors. The registered buffer and ECC logic help maintain data integrity in multi-socket server workloads.

Not for non-server platforms

Systems that require unbuffered non-ECC memory, a different DDR generation, or a pin count other than 240 cannot use these modules. Boards limited to single-rank DIMMs or to capacities below 4 GB per slot are also incompatible. Mixing x4 and x8 chips inside the same bank is not supported by the validated motherboards.

Installed in matched pairs

The Supermicro boards validated for this kit operate in dual-channel mode with three banks of two sockets each, so modules must be added in identical pairs to enable that bandwidth. The platform maximum is 48 GB across all six sockets, and a 64-bit operating system is required to address the full amount.

Domande su questo articolo

Does the kit include four 4 GB modules or is it a single 16 GB stick?

The kit contains four 4 GB modules, giving a total of 16 GB.

Should I choose single-rank or dual-rank modules for the Supermicro X7DCA boards?

These modules are 2Rx4 dual-rank; the board accepts both ranks but they must not be mixed within the same bank.

What does the PC2-5300 rating mean for actual throughput in the server?

PC2-5300 indicates a peak transfer rate of 5300 MB/s at 667 MHz.
