Compatible 8 GB DDR3L Server Module

This A-Tech module is an 8 GB DDR3L 1333 ECC Registered DIMM built as a direct replacement for the IBM-Lenovo 43X5318 part number. It operates at 1.35 V with CL9 latency and a 2Rx4 rank organisation using major-brand chips. The 240-pin form factor fits standard DDR3 server sockets.

Suited for ECC Registered DDR3 Slots

It suits administrators upgrading or repairing IBM-Lenovo servers that require DDR3L ECC Registered memory at 1333 MHz. Systems needing unbuffered UDIMMs, higher speeds, different voltages or larger single-module capacities should look at other memory types.

1.35 V DDR3L Voltage Decides Fit

The single specification that decides compatibility is the 1.35 V DDR3L operating voltage combined with ECC Registered signalling. Only platforms explicitly qualified for DDR3L 1333 RDIMM 2Rx4 modules at this voltage will accept the part.

Questions about this item

Will this 240-pin DDR3L RDIMM fit my server's DIMM slots?

The module uses the standard 240-pin DDR3 DIMM form factor and 1.35 V DDR3L signalling, so it fits any server board that accepts DDR3L registered DIMMs.

What is the correct way to seat this 2Rx4 ECC module during installation?

Align the notch with the slot key, press straight down until both retention clips click, and verify the system detects the full 8 GB at 1333 MHz.

When should I plan to replace this registered ECC memory?

Replace it only if diagnostics report correctable ECC errors rising over time or the module fails memtest; otherwise DDR3L RDIMMs typically run for the server's service life.
