Target Server Upgrade

This A-Tech module adds eight gigabytes of DDR3L registered ECC memory to compatible IBM-Lenovo servers and workstations. It is built for administrators who need dependable capacity expansion in 240-pin DIMM slots. Systems that require unbuffered or non-ECC memory cannot use this part.

Critical Compatibility Check

The single specification that decides fit is the registered ECC 2Rx4 organisation at DDR3L 1333 PC3L-10600 with 1.35 V operation. Verify the motherboard qualified-vendor list for the exact IBM-Lenovo part numbers listed by the supplier before ordering.

Thermals and Power

Low-voltage DDR3L reduces DRAM power draw compared with standard 1.5 V modules, helping keep DIMM temperatures modest under typical server workloads. The registered buffer adds negligible current, and passive cooling in normal chassis airflow is sufficient.

Questions about this item

What does the 1333 MHz rating mean when the module is installed in a server?

The module runs at 1333 MHz DDR3L, delivering PC3L-10600 bandwidth with CL9 latency and 1.35 V operation.

How does the registered DDR3L interface affect what the system can use?

Registered DDR3L 240-pin DIMM with ECC requires a server chipset that supports registered memory; it will not work in standard unbuffered desktop boards.

What physical slot and clearance does this 8 GB stick need?

240-pin DDR3 DIMM form factor; fits standard server DIMM slots with 1.35 V keying and 2Rx4 chip layout.
