64GB DDR5 4800 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 4800 registered DIMMs with ECC and CL40 latency. The modules run at 1.10V and use a 288-pin RDIMM form factor. They are validated for the ASUS RS720-E11-RS12U 2U dual-socket server.

Suited for memory upgrades on the named ASUS server

This kit fits administrators expanding memory in the specified ASUS 2U dual-socket platform. Builders needing non-ECC UDIMMs, higher frequencies, lower latencies or different form factors should look elsewhere.

288-pin DDR5 RDIMM registered ECC

The 288-pin DDR5 RDIMM registered ECC specification determines mechanical and electrical compatibility with the target server. Confirm the platform requires registered ECC RDIMMs before ordering.

Questions about this item

Does my ASUS RS720-E11-RS12U server need a specific BIOS version or CPU to run this 4800 MHz DDR5 ECC RDIMM kit?

The modules are built to the DDR5 4800 PC5-38400 JEDEC standard with 1.10 V operation and CL40 latency; any RS720-E11-RS12U that supports DDR5 RDIMMs will recognise them at that speed without extra configuration.

Can I mix these 1Rx4 registered DDR5 sticks with older 2Rx4 or 1Rx8 RDIMMs already in the chassis?

Each module is a single-rank 1Rx4 registered DIMM; mixing ranks or widths on the same channel is not recommended and may prevent the server from posting or force all channels to the slowest common timing.

How do I confirm the kit is running at the rated 4800 MT/s with ECC active after installation?

Enter the BIOS or use a hardware inventory tool such as dmidecode or IPMI; both will show each 32 GB module at 4800 MT/s, 1.10 V, CL40 and report ECC type as registered ECC.
