Compatible Lenovo Converged Appliance modules

This 32GB DDR4 2400MHz ECC RDIMM is built for Lenovo Converged Appliance HX1310, HX2310-E, HX2710-E, HX3310 and HX3310-F systems. It replaces Lenovo part numbers 46W0832, 46W0833, 46W0835, 4X70G88320 and 4X70M09263. The module runs at 1.2V with CL17 latency.

Server and workstation memory only

This registered ECC DIMM is intended for servers, workstations and compatible NAS units that require registered memory. It will not work in standard desktop computers or laptops that use unbuffered modules. Builders who need unbuffered memory for consumer platforms should look elsewhere.

288-pin DDR4 ECC registered form factor

The module uses a 288-pin DDR4 ECC registered design with a 2Rx4 rank configuration. This specific form factor and registration type determine whether the DIMM will be accepted by the target system. Verify that the platform requires registered ECC memory before purchasing.

Questions about this item

How do I install the 288pin RDIMM into my Lenovo HX2310-E and what step is commonly missed?

Power down the appliance, open the chassis, align the 288pin module with the DDR4 slot, press firmly until the retention clips click, then verify in BIOS that ECC Registered mode is active; the step often missed is enabling ECC in the firmware after physical installation.

What maintenance or replacement will this 32GB 2Rx4 module need over its service life?

No scheduled maintenance is required for the DDR4 RDIMM itself; replacement only becomes necessary if a memory error count exceeds the platform threshold or if a capacity upgrade is planned for the HX3310-F.

What limit appears first when the 2400MHz CL17 kit runs sustained workloads on the HX2710-E?

The thermal envelope of the fan-cooled memory zone typically reaches its ceiling before the 1.2V modules hit voltage or frequency throttling limits.
