32 GB DDR5 4800 ECC RDIMM for SuperMicro SYS-221HE

This 32 GB module is a DDR5 4800 CL40 registered DIMM with ECC and 1Rx4 organisation. It runs at 1.1 V and uses the 288-pin RDIMM form factor. The part is validated for the SuperMicro SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR SuperServer platforms.

Check motherboard slots and memory population rules

Verify that your SYS-221HE system has a free 288-pin DDR5 RDIMM slot and consult the server manual for approved population order. The platform must support DDR5 4800 registered ECC modules at 1.1 V. Mixing ranks or speeds can prevent boot, so match the existing configuration exactly.

Suited for IT teams expanding validated SuperMicro

Ideal for administrators adding capacity to the listed SYS-221HE models where registered ECC memory is required. Not a fit for consumer desktops, laptops or workstations that accept only unbuffered non-ECC DDR5. Buyers needing unregistered DIMMs or different speeds should look at other memory lines.
