2 TB DDR5 server kit

This kit supplies 2 TB of DDR5 4800 registered ECC memory in sixteen 128 GB modules. It is built for the ASUS RS720Q-E11-RS8U 2U4N high-density server. Each module runs at 1.1 V with CL40 latency and a 4Rx4 organisation. The 288-pin RDIMM form factor fits the server's memory slots directly.

Who this suits and who it does not

IT teams upgrading the named ASUS 2U4N platform to its maximum supported capacity will find a matched, tested set. Buyers who need non-registered DIMMs, lower voltages, different speeds or smaller capacities cannot use this kit. Systems that require UDIMM or LRDIMM modules are also incompatible.

Deciding specification: 4Rx4 registered ECC

The 4Rx4 registered ECC organisation is the single factor that determines whether the motherboard accepts these modules. The memory controller must support quad-rank registered operation with error correction at DDR5 4800. Verify the server documentation for this exact configuration before purchase.

Questions about this item

What practical limit does the DDR5 4800 PC5-38400 standard impose on this memory kit?

The kit runs at 4800 MT/s with a PC5-38400 bandwidth rating, so throughput is capped at that JEDEC DDR5 speed grade.

What physical slot and pin count does this 288-pin RDIMM kit require in the ASUS RS720Q-E11-RS8U server?

Each 128 GB module uses a standard 288-pin DDR5 RDIMM form factor and must occupy one of the server's registered DIMM slots.

How are the 16 modules installed, and which population step is most often missed?

Insert all 16 modules into the correct RDIMM slots following the motherboard's population sequence; the step most often missed is matching the 4Rx4 rank layout to the prescribed channel order.
