Server ECC Registered RDIMM

This 32 GB DDR4 module runs at 2933 MHz with CL21 latency and 1.2 V operation. It is built for workstations, servers and NAS systems that require registered ECC memory. The 2Rx4 dual-rank organisation and 288-pin form factor match the listed Supermicro X11 motherboards.

Registered ECC cannot mix with unbuffered

Registered DIMMs use a buffer that adds one clock cycle and changes the electrical load on the memory bus. Motherboards designed for unbuffered memory will not initialise these modules. Backward compatibility covers 2133, 2400 and 2666 MHz speeds, but the registered signalling remains mandatory.

Verify motherboard supports registered ECC

Check that your Supermicro board is one of the X11DPT-L, X11DPT-PS, X11DPU, X11DPX-T or X11DSC+ models. Confirm the BIOS is current and that no unbuffered DIMMs are already installed. This product is not suitable for standard desktop computers.

Questions sur cet article

Should I pick the 32GB module or a different capacity for my Supermicro X11DPT-L?

This listing is for a single 32GB module; choose the quantity that matches the total memory your board supports and the number of free slots you have.

What does the 2933MHz rating deliver once installed in a server?

The module runs at 2933MHz CL21 at 1.2V, providing 23400 MB/s peak bandwidth per stick; the system will clock it down automatically if the CPU or chipset only supports lower speeds.

How does the DDR4 ECC Registered interface limit real-world use?

The 288-pin DDR4 ECC Registered form factor only fits server and workstation boards — it will not work in standard desktop motherboards and cannot be mixed with unbuffered DIMMs.
