Capacity and purpose

This NEMIX RAM module delivers 48GB of DDR5 server memory in a single registered DIMM. It is built for enterprise platforms that require error-correcting code and registered signalling for data integrity.

Speed and latency gate

The module runs at 6400 MT/s with a CAS latency of 52 and operates at 1.1V, so the platform must support DDR5 6400 and the registered command/address protocol to function.

Build integration

The 288-pin RDIMM plugs directly into compatible server motherboards and presents a 2Rx8 organisation to the memory controller. It is not for desktop or laptop computers that lack registered ECC support.

Questions about this item

What does the 6400 MT/s rating deliver in a real server?

The module runs at 6400 MT/s with CL52 timing at 1.1 V, giving 48 GB of registered ECC capacity per DIMM for DDR5-6400 platforms.

How does the DDR5 interface and PC5-51200 rating limit usable speed?

The PC5-51200 designation confirms a 6400 MT/s data rate; the memory controller of the host system determines the final operating speed.

What physical slot and clearance does this 288-pin RDIMM need?

It fits a standard 288-pin DDR5 RDIMM socket and requires a server motherboard that supports registered ECC DIMMs.
