32GB DDR5 ECC RDIMM for ASUS RS720Q-E11-IM

This 32GB registered DDR5 module is built for the ASUS RS720Q-E11-IM immersion-cooled server. It delivers error-correcting code memory for workloads that cannot tolerate data corruption. The single 1Rx4 rank fills one 288-pin slot with 32GB of capacity. It is not for desktops or workstations that require unbuffered memory.

Registered DDR5 4800 CL40 at 1.1V

The module runs at DDR5 4800 (PC5-38400) with CAS latency 40 and a 1.1V operating voltage. Registered buffering and on-die ECC protect data integrity under sustained load. Major OEM Samsung, Micron or Hynix chips are used. Systems that need unbuffered DIMMs or a different voltage will not accept this part.

Tool-free slot insertion with seated verification

Align the notch on the 288-pin edge connector with the motherboard key and press evenly until the retention clips click. The registered design adds a clock cycle, so the BIOS must support registered DIMMs or the server will not post. Mixing registered and unbuffered modules prevents boot.

Questions about this item

What does the 4800 MT/s rating mean once the module is installed in the ASUS RS720Q-E11-IM?

The module runs at DDR5 4800 MT/s, delivering PC5-38400 bandwidth for the server's memory subsystem.

How does the registered ECC interface affect usable capacity and error handling?

Registered ECC adds a buffer for signal integrity and corrects single-bit errors, essential for the 1Rx4 organisation in this server.

Will the 288-pin RDIMM fit the memory slots on the RS720Q-E11-IM without a heat spreader?

Yes, the bare 288-pin DDR5 RDIMM matches the server's slot keying and low-profile design.
