Server capacity upgrade

This 32GB DDR3L module targets administrators expanding memory in compatible IBM-Lenovo servers. The registered ECC design supports data integrity for virtualisation, database and compute workloads. Single-module population simplifies capacity planning in dense chassis.

DDR3L interface limits

The DDR3L 1066 standard caps transfer rate at PC3L-8500 and operates at 1.35V, lower than classic DDR3. Registered buffering adds a clock cycle of latency but enables higher densities per channel. Systems must accept 4Rx4 organisation and 240-pin DIMM form factor to use this module.

Replaces legacy IBM-Lenovo parts

This module replaces IBM-Lenovo part numbers 78P1539, 90Y3101, 90Y3103, 90Y3206, 93Y4300, EEMF and EM4D. The upgrade is worthwhile when the platform supports DDR3L 1066 registered ECC and the workload demands more capacity than the original configuration provided.

Questions about this item

Which capacity should I choose for my server?

This module provides 32GB in a single 240-pin DDR3L DIMM, so select it when your system needs a 32GB registered ECC stick.

What does the 1066MHz speed mean once installed?

The module runs at DDR3L 1066 (PC3L-8500) with CL7 latency at 1.35V, delivering that data rate when the platform supports DDR3L registered ECC memory.

What interface does this use and what does it limit?

It uses a 240-pin DDR3L registered ECC interface, which caps the memory bus to DDR3L 1066 speeds and requires a server or workstation that accepts 4Rx4 registered modules.
