Lenovo 46W0835 Compatible DDR4 RDIMM

This 32 GB registered ECC module runs at DDR4 2400 with CL17 latency and 1.20 V operation. It uses a 2Rx4 organisation on a 288-pin RDIMM form factor built with major OEM chips. The part matches Lenovo 46W0835 specifications for server and workstation memory upgrades.

For ECC registered server or workstation slots only

Suits administrators upgrading Lenovo systems that require registered DDR4 ECC RDIMMs at this speed and rank. Not for desktop boards that accept only unbuffered non-ECC UDIMMs, nor for platforms needing DDR5, different voltages, or higher frequency modules.

DDR4 2400 CL17 2Rx4 registered ECC specification

The DDR4 2400 PC4-19200 CL17 2Rx4 registered ECC profile determines whether the memory controller will initialise the module correctly. Verify that your Lenovo server or workstation qualification list includes this exact speed, rank and voltage combination before purchase.

Questions about this item

Will the CL17 latency limit throughput when the module runs at DDR4 2400 all day?

CL17 is the rated CAS latency at 2400 MT/s; the module operates at that timing continuously without additional throttling.

Does the registered ECC RDIMM generate extra heat or noise at 1.20 V in a fully populated server?

The module runs at 1.20 V with no heat spreader; registered ECC RDIMMs add negligible thermal load and produce no audible noise themselves.

Must the Lenovo system already support 2Rx4 registered DDR4 2400 DIMMs for this 32 GB stick to work?

Yes — the motherboard must accept 288-pin DDR4 RDIMMs at 2400 MT/s with 2Rx4 organisation and ECC registered operation.
