32 GB LRDIMM for IBM systems

This Axiom 46W0800-AX module provides 32 GB of DDR4 memory in a 288-pin LRDIMM form factor. It is built specifically for compatible IBM servers and workstations that require registered ECC memory. The module operates at DDR4 2133 with a CAS latency of CL15 and a voltage of 1.20 V.

Sustained operation with ECC stability

Error-correcting code detects and corrects single-bit errors during continuous operation, helping maintain data integrity under sustained workloads. The DDR4 standard reduces power demand by 20 percent compared to DDR3, which lowers thermal output during extended use. CL15 timing at 2133 MHz supports consistent throughput for memory-intensive server tasks.

DDR4 2133 interface limits

The PC4 17000 rating defines the maximum standard bandwidth available on this DDR4 2133 interface. LRDIMM buffering allows higher densities than standard RDIMMs, but the memory controller must support the load-reduced topology. Systems limited to DDR3 speeds or non-ECC configurations cannot use this module.

Questions about this item

Does the 1.20 V DDR4 2133 module run cooler than DDR3 when the server is under load all day?

DDR4 operates at 1.20 V and the supplier highlights a 20 % reduced power demand versus DDR3, which lowers heat output during continuous operation.

What must the system already have to accept this 288-pin LRDIMM?

An IBM server that supports DDR4-2133/PC4-17000 LRDIMMs with ECC and CL15 timing.

Can I add this 32 GB stick alongside existing DDR3 DIMMs in the same machine?

No — DDR4 uses a different 288-pin keying and voltage, so it cannot share a memory channel with DDR3 modules.
