Server-specific DDR3 ECC registered kit

This 8 GB kit contains two 4 GB DDR3-1333 registered DIMMs built for IBM System x3550 M2 models 4198 and 7946. ECC and registered signalling protect data integrity in 24/7 server workloads. The modules run at 1.5 V with CL9 9-9-9 timing and use a 2Rx4 organisation. Computer Memory Solutions guarantees compatibility with the listed systems.

Sustained-load behaviour and clock limits

Under continuous operation the memory adheres to the platform's rank and population rules. Quad-rank modules are capped at 1066 MHz, and installing two per bank forces a further drop to 800 MHz. The system supports a maximum of six quad-rank DIMMs per CPU or twelve with two CPUs. Modules automatically clock down to 1066 MHz or 800 MHz depending on the installed Xeon and bank population.

Pre-installation checklist

Verify that your server is an IBM System x3550 M2 4198 or 7946 before ordering. Confirm the number of populated DIMM slots and the Xeon model installed, as these determine the final operating speed. The kit provides two 240-pin sticks; ensure enough free sockets remain for your desired total capacity up to the platform maximum of 128 GB across 16 sockets.

Questions sur cet article

How much power does the 1.5V DDR3-1333 kit draw when the server runs continuously?

Each module operates at 1.5V; total draw depends on how many of the 16 sockets are populated and the Xeon model installed.

What must the buyer already own for this 240-pin registered ECC kit to function?

An IBM System x3550 M2 (4198 or 7946) with a compatible Xeon processor and free 240-pin DIMM slots.

Will these 2Rx4 modules run at 1333MHz alongside older 800MHz or 1066MHz DIMMs already in the system?

The kit automatically clocks down to 1066MHz or 800MHz depending on the Xeon model and bank population; quad-rank limits apply.
