64 GB DDR4 ECC RDIMM for Supermicro servers

This 64 GB DDR4 2933 MHz registered ECC module is built for Supermicro X11SP series motherboards including the X11SPi-TF, X11SPL-F, X11SPM-F, X11SPM-TF and X11SPM-TPF. It targets administrators who need to expand memory capacity on supported server or workstation platforms without mixing with unbuffered DIMMs.

1.2 V operation and JEDEC compliance

The module runs at a standard 1.2 V and conforms to JEDEC DDR4 specifications, so power draw and thermal output remain within the limits defined for PC4-23400 registered DIMMs. No heat spreader is fitted, relying on normal chassis airflow to keep temperatures in check during typical server workloads.

288-pin registered form factor

The 288-pin RDIMM plugs directly into compatible Supermicro DDR4 slots and will also operate at 2133, 2400 or 2666 MHz if the platform requires a lower speed. It cannot be used in standard desktop boards or mixed with unbuffered memory, so buyers must confirm their system requires registered ECC DIMMs before purchase.

Questions sur cet article

How do I install the 288pin DDR4 ECC RDIMM in a Supermicro X11SPM-F and what step is often missed?

Power down the server, open the chassis, align the notch on the 288pin module with the slot key, press firmly until both latches click, then verify in BIOS that the 64GB stick registers at 2933MHz CL21; the step often missed is confirming the registered ECC mode is enabled in firmware.

What maintenance or replacement will the 2R9D42R464GB module need over its service life?

The module has no heat spreader and no moving parts, so routine maintenance is limited to keeping server airflow clean; replacement is only required if a memory test reports correctable ECC errors rising above threshold or a DIMM fails POST.

What limit appears first when the 64GB PC4-23400 CL21 kit runs sustained workloads?

The registered buffer and 1.2V operation keep thermals low, so the first limit is usually the memory controller’s maximum supported rank count or total capacity per channel before bandwidth saturates at 2933MHz.
