64 GB DDR5 RDIMM for servers

This single 64 GB DDR5 module runs at 4800 MHz with CL40 latency and 1.1 V operation. It uses a 288-pin registered DIMM layout with ECC and a 2Rx4 dual-rank x4 organisation. The module is built for server and workstation platforms that require registered ECC memory.

Registered ECC limits desktop use

Registered signalling and ECC require a platform memory controller that supports both features. Standard desktop and laptop boards lack this support, so the module will not function in those systems. Compatibility must be confirmed against the server or workstation memory qualification list before installation.

Replaces lower-capacity RDIMMs

Adding this 64 GB module increases total memory capacity without occupying additional slots. The upgrade is worthwhile when workloads exceed the limits of smaller registered DIMMs and the platform supports the DDR5 4800 registered ECC standard.

商品問答

Should I pick the single 64 GB module or add a second one?

This listing is a single 64 GB DDR5 4800 RDIMM; add a second identical module only if your server board has a free 288-pin slot and the manual approves dual-rank population.

What does the 4800 MHz speed deliver in my server?

The module runs at DDR5 4800 with CL40 latency at 1.10 V, giving the platform its rated transfer rate when the memory controller is configured for that speed.

Is the PC5-38400 label the same as DDR5 4800, and what does it limit?

PC5-38400 is the JEDEC designation for DDR5 4800; the registered buffer and ECC logic operate within that spec, so the system cannot exceed the 4800 MT/s data rate.
