128 GB DDR4 ECC Registered RDIMM

This 128 GB DDR4 3200 CL22 8Rx4 registered DIMM is built for ASUS rack servers including the RS720-E10-RS24U, RS720Q-E10-IM and RS720Q-E10-RS8U. It targets administrators who need a single high-capacity module to expand memory in compatible workstation or NAS platforms.

Registered ECC limits and compatibility

Registered ECC memory cannot be mixed with unbuffered or load-reduced DIMMs and will not work in standard desktop computers. The module operates at 1.2 V and is backward compatible with 2133 MHz, 2400 MHz, 2666 MHz and 2933 MHz bus speeds.

8Rx4 rank configuration decides fit

The 8Rx4 organisation determines whether the server’s memory controller can address the full 128 GB per slot. Verify the platform’s qualified vendor list for this rank structure before purchase.

Spørgsmål om denne vare

Should I choose the 128GB 8Rx4 module or add multiple smaller DIMMs to reach the same capacity?

The 128GB 8Rx4 RDIMM delivers the full capacity in a single slot, leaving remaining channels free for future expansion while keeping rank-per-channel limits within the server's memory controller specification.

What does the 3200MHz speed rating actually deliver inside an ASUS RS720 rack server?

The module runs at DDR4 3200 with CL22 timing at 1.2V; the server's memory controller will operate it at the highest supported data rate up to 3200MT/s, dropping to 2933, 2666, 2400 or 2133MT/s if the CPU or populated channel count requires a lower speed.

How does the 288-pin DDR4 ECC Registered interface limit what I can install alongside this module?

The RDIMM is keyed for 288-pin DDR4 slots only and uses registered ECC signalling; it cannot be mixed with unbuffered or load-reduced DIMMs, and every populated slot must match the same registered ECC type for the system to initialise memory training.
