8GB DDR4 2133 ECC RDIMM for Lenovo Servers

This 8GB DDR4 2133MHz ECC registered DIMM is built for IBM-Lenovo servers and workstations that require registered memory with error correction. It operates at 1.20V with CL15 latency and uses a 2Rx8 organisation. The module fits 288-pin DDR4 slots and replaces Lenovo part numbers 46W0792, 46W0794, 47J0252 and 4X70G78061.

Registered ECC with 2Rx8 organisation

The single specification that determines fit is the registered ECC RDIMM design combined with a 2Rx8 rank structure. Systems that require unbuffered UDIMMs or a different rank configuration will not accept this module. Verify that your platform supports registered ECC DDR4 at 2133MHz before ordering.

Lifetime warranty and US-based support

The bundled lifetime warranty and complimentary United States technical support provide direct assistance for compatibility checks and troubleshooting. This service layer helps confirm the module matches your system's qualified vendor list before installation and covers the part for its usable life.

Questions about this item

Will the 2133 MHz speed actually run at that frequency in my server?

The module is rated for DDR4 2133 (PC4-17000) and will operate at that speed provided the system memory controller supports it; otherwise it downclocks to the highest supported frequency.

How does the registered ECC design affect compatibility?

This is an ECC RDIMM (2Rx8, CL15, 1.20 V) using DDR4 288-pin form factor; it only works in platforms that explicitly support registered ECC memory and cannot be used in unbuffered or non-ECC slots.

Does the 288-pin DIMM fit standard server memory slots?

Yes, the module uses the standard DDR4 288-pin RDIMM form factor, so it installs in any server or workstation slot designed for registered DDR4 DIMMs.
