Server-Specific DDR4 Upgrade

This 32GB kit contains two 16GB DDR4 2133 registered ECC modules built for the IBM System x3650 M5 5462-xxx. It installs as a matched pair in the server's 288-pin DIMM slots and runs at 1.2V with CL15 timing.

Suited for x3650 M5 Expansion

The modules suit administrators adding capacity to an x3650 M5 that requires registered ECC memory. Builders needing unbuffered ECC, load-reduced DIMMs, or speeds above 2133MHz should look elsewhere because this system does not support mixing RDIMM and LRDIMM types.

32GB Installed Capacity

The kit adds 32GB toward the platform's 384GB RDIMM ceiling or 1.50TB LRDIMM maximum across 24 sockets. Each CPU provides 12 slots, so two modules occupy one channel pair and leave ample headroom for further registered ECC upgrades.

Questions about this item

What server model must I already own for this CMS CM2048722133ECCREG kit to be guaranteed compatible?

This 32 GB kit is guaranteed compatible with the IBM System x3650 M5 5462-xxx server only.

If my x3650 M5 currently runs slower DDR4 modules, will this 2133 MHz registered ECC kit operate correctly alongside them?

Faster memory will clock down to the optimal speed and voltage supported by the installed processor and module count.

After installing both 16 GB sticks, how can I confirm the system recognises the full 32 GB of registered ECC memory?

The server BIOS or operating system memory report should show 32 GB total capacity with ECC registered DIMM status.
