System-Specific DDR3 ECC Registered Memory

This 16 GB kit contains two 8 GB DDR3 1333 MHz registered DIMMs built for IBM System x3650 M2 servers. It targets administrators upgrading model numbers 4199 or 7947 who need error-correcting, registered modules.

Thermals Noise and Power Draw

Each module runs at the standard 1.5 V DDR3 voltage with CL9 9-9-9 timings. Registered buffering reduces electrical load on the server memory controller, keeping power draw and heat output within the platform’s original thermal envelope.

Capacity and Compatibility Limit

The kit provides 16 GB total across two 240-pin sticks, while the supported systems accept up to 128 GB across 16 sockets. Buyers needing larger single modules or non-ECC unbuffered memory should look elsewhere.

Questions about this item

How do I install the 240-pin DDR3 registered DIMMs in the IBM System x3650 M2 and which step is often missed?

Power off the server, open the chassis, align each 240-pin module with the slot key and press firmly until the ejector clips lock; the step often missed is populating slots in the exact bank order shown in the system service guide so the registered signal timing stays valid.

What maintenance or replacement will the 16 GB ECC registered kit need during its service life?

The modules have no moving parts and require no scheduled maintenance; replacement is only needed if a DIMM fails ECC correction or the server is upgraded beyond the 128 GB maximum across the 16 sockets.

What limit appears first when the kit runs at 1333 MHz under sustained load?

The 1.5 V DDR3 voltage and CL9 timing define the thermal envelope; sustained full-speed operation will hit the module temperature rating before bandwidth or capacity limits are reached.
