OWC 32GB DDR4 2133MHz ECC RDIMM

This 32GB DDR4 2133MHz CL15 registered ECC module is built for Lenovo System x3500 M5, x3550 M5 (5463) and x3650 M5 (5462) servers. It operates at 1.2V using a 288-pin 2Rx4 configuration. It is not compatible with standard desktop computers or unbuffered memory.

ECC registered operation

The registered ECC design adds error correction and signal buffering for server stability. It replaces Lenovo part numbers 00FC888, 4X70G88311, 95Y4808 and 95Y4810. Mixing this module with unbuffered memory will prevent the system from booting.

Simple DIMM installation

Installation follows standard server DIMM procedure: power down, open the chassis, align the notch and press firmly until the latches click. The most common issue is seating the module incompletely or mixing registered and unbuffered DIMMs in the same channel.

Questions sur cet article

Will the 32GB DDR4 2133MHz CL15 ECC Registered RDIMM need any firmware updates or battery replacements over its service life?

No firmware updates or battery replacements are required for this memory module; it is a passive component with no onboard firmware or battery.

What thermal or electrical limit appears first when the 1.2V 2Rx4 module runs continuously at 2133MHz in a Lenovo System x3550 M5?

The module operates within JEDEC DDR4 limits at 1.2V and CL15; sustained loads stay inside the rated voltage and timing envelope without throttling.

How much heat and power does the 288-pin ECC Registered DIMM produce when installed in a Lenovo System x3650 M5 running all day?

At 1.2V the module draws low power and has no heat spreader, so it adds minimal heat and runs silently inside the server chassis.
