Lenovo 49Y1563 Server Memory Module

Lenovo 49Y1563 is a 16GB DDR3L ECC RDIMM Module. It delivers stable, reliable Memory for enterprise Server workloads. The part number is the reliable way to identify it, because accessories of this kind are often visually identical across generations that are not interchangeable.

Population rules. Memory is matched to the platform generation, the speed and the rank, and mixing types can stop a system booting rather than simply running slower. Populate in the order the vendor specifies: on most platforms the channels have to be filled evenly, and a technically valid module in the wrong slot will either not be seen or will drag the whole bank down to a lower speed.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. Tell us the chassis or model it has to work with and we will confirm the part before anything ships. Quotes go out the same or next working day.

The Lenovo 49Y1563 is a 16GB DDR3L ECC RDIMM memory module designed for enterprise servers. It delivers stable and reliable performance, so it supports virtualization, databases, and business-critical workloads.

It operates at 1333MHz (PC3L-10600). As a result, it provides consistent data transfer speeds for server environments. In addition, it uses ECC (Error-Correcting Code) technology, which detects and corrects memory errors automatically. This ensures data integrity and system stability.

The module uses a registered DIMM (RDIMM) design. Therefore, it reduces electrical load on the memory controller and improves reliability in multi-DIMM server configurations.

It operates at a low voltage of 1.35V (DDR3L). Moreover, this improves energy efficiency and reduces heat output compared to standard DDR3 memory.

The 240-pin DIMM form factor ensures compatibility with IBM/Lenovo System x servers such as x3650 M4 and similar platforms. Because of this, it is widely used in legacy enterprise systems.

Overall, the Lenovo 49Y1563 is a reliable and cost-effective memory upgrade for older server environments that require stability and ECC protection.
