Exact-Match DDR4 RDIMM for Supermicro X12SPA-TF

This 8 GB DDR4 3200 MHz registered ECC module is built for servers that require a 1Rx8 CL22 1.20 V DIMM. It targets administrators upgrading a Supermicro X12SPA-TF motherboard with the precise rank, voltage and timing the memory controller expects.

Verify motherboard population rules before ordering

Consult the system or motherboard manual for supported capacities, approved DIMM population order and installation steps. The board demands a 288-pin RDIMM; UDIMM or SODIMM modules will not fit or function in this platform.

Registered design offloads the memory controller

The buffered architecture allows every slot to run fully populated at rated speed while ECC corrects single-bit errors on the fly. No heat spreader is fitted, so airflow across the bare PCB must be maintained by the server chassis fans.

Questions about this item

Does the module arrive as a single 8 GB stick or do I need to order multiple pieces to reach that capacity?

The package contains one 8 GB DDR4 3200 MHz RDIMM, so no extra modules are required to install 8 GB.

Why is this CL22 1Rx8 registered ECC version the correct choice for my Supermicro X12SPA-TF?

The board requires a 288-pin registered ECC DIMM at 1.2 V with 1Rx8 organisation and CL22 timing; this part matches those exact specifications.

What does the PC4-25600 rating mean once the DIMM is installed in the server?

It indicates a DDR4 3200 MT/s data rate, which the memory controller will run at provided the motherboard supports that speed.
