Targeted server upgrade

This 16GB kit contains two 8GB registered ECC DIMMs built to the DDR2 667MHz PC2-5300 standard. It is designed exclusively for the Supermicro X7DCL-i, X7DCT, X7DCT-10G, X7DCT-3 and X7DCT-3F server platforms listed by the supplier. The modules install in matched pairs to enable dual-channel operation on those boards.

Suited for maintainers of these specific

It suits administrators restoring or expanding memory in the exact models named above. It does not suit systems that take unbuffered DDR2, nor boards that cannot accept registered DIMMs or require single-rank modules. Builders working with any other platform should look elsewhere because compatibility is guaranteed only for the listed part numbers.

Registered ECC DDR2 667MHz

The single specification that decides fit is the registered ECC DDR2 667MHz (PC2-5300) interface in a 240-pin DIMM form factor. The target motherboard must support registered error-correcting modules at this speed and voltage. If the board requires unbuffered memory, a different DDR generation, or a non-ECC configuration, these modules will not work.

Questions about this item

Does this kit fit the 240-pin DDR2 slots on a Supermicro X7DCL-i server board?

Yes, the modules are 240-pin DDR2 SDRAM DIMMs designed for the X7DCL-i, X7DCT, X7DCT-10G, X7DCT-3 and X7DCT-3F server boards listed in the compatibility data.

What is the correct way to install the two 8 GB sticks so the server runs in dual-channel mode?

Install the pair into the same memory bank — the X7DCL-i has three banks of two sockets each — and always populate both sockets of a bank with identical modules; mixing x4 and x8 chips inside one bank is not supported.

When should the registered ECC DIMMs be replaced if the server starts logging corrected memory errors?

Replace the modules when the system management log shows a rising count of correctable ECC events, indicating the chips are degrading; the kit carries a limited lifetime warranty for exchange when purchased directly from the manufacturer.
