ASUS RS720Q-E11-IM memory kit

This 32 GB kit contains two 16 GB DDR5 4800 registered DIMMs built for the ASUS RS720Q-E11-IM server. ECC and registered buffering protect data integrity in multi-node, immersion-cooled deployments. The modules operate at 1.1 V with a CL40 latency profile.

DDR5 4800 registered DIMM limits

Registered DIMMs add a clock cycle for address buffering, so raw latency is higher than unbuffered alternatives. The 4800 MT/s transfer rate caps peak bandwidth at the PC5-38400 level. Immersion cooling does not change the electrical specification or the JEDEC voltage of 1.1 V.

1Rx8 organisation decides fit

Each module uses a single-rank 1Rx8 layout, which determines how the memory controller populates the RS720Q-E11-IM slots. Builders needing dual-rank density or higher per-slot capacity must choose a different part number.

Questions about this item

Should I choose the 2x16 GB kit or a single 32 GB module for the ASUS RS720Q-E11-IM?

The kit supplies two 16 GB RDIMMs for 32 GB total, letting the dual-channel architecture of the RS720Q-E11-IM run at full width.

What does the 4800 MT/s rating deliver once installed in the server?

The modules operate at DDR5 4800 with CL40 latency and 1.1 V, giving the rated PC5-38400 bandwidth when the platform trains them at that speed.

Does the 288-pin RDIMM interface limit capacity or speed on this platform?

Each 288-pin RDIMM is a 1Rx8 registered ECC module; the RS720Q-E11-IM memory controller sets the practical ceiling for both capacity per slot and maximum data rate.
