1TB DDR4 ECC LRDIMM Kit

This 1TB kit contains eight 128GB DDR4 2933 ECC Load Reduced DIMMs built for the Supermicro X11SPD-F motherboard. The modules run at 1.2V with CL21 latency and use an 8Rx4 rank configuration. They are designed for server, workstation and NAS environments that require registered ECC memory.

Verify motherboard and memory type

Confirm your system is the Supermicro X11SPD-F before ordering. This kit uses 288-pin DDR4 ECC Load Reduced DIMMs and will not work in standard desktop computers. It also cannot be mixed with unbuffered or ECC registered memory. Backward compatibility covers 2133, 2400 and 2666MHz speeds if the platform requires a lower frequency.

Suits X11SPD-F capacity upgrades

Ideal for administrators expanding a Supermicro X11SPD-F to its maximum supported memory. Not suitable for desktop PCs, consumer laptops or any system that requires unbuffered or standard registered ECC modules. Buyers needing a different form factor, voltage or rank layout should look elsewhere.

Questions about this item

Does the kit include all eight 128GB LRDIMMs or must any modules be purchased separately?

The kit contains eight 128GB DDR4 2933 CL21 ECC Load Reduced DIMMs, providing the full 1TB capacity in a single package; no additional modules are required.

Should I choose this 1TB eight-module kit or a smaller capacity for the Supermicro X11SPD-F?

Select this 1TB kit when the X11SPD-F has eight available DIMM slots and the workload needs maximum memory capacity; smaller kits leave slots open for future expansion.

What does the DDR4 2933 CL21 rating mean once the modules are installed in the X11SPD-F?

The modules run at 2933MHz with CAS latency 21 at 1.2V; the X11SPD-F will also operate them at 2666MHz, 2400MHz or 2133MHz if the platform requires a lower speed.
