4GB DDR3L ECC UDIMM for servers

This 4GB DDR3L module runs at 1600 MHz with CL11 latency and operates at 1.35V. It is an unbuffered ECC UDIMM built with a 1Rx8 rank using major brand chips. The 240-pin DIMM is designed for server and workstation systems that require error-correcting memory.

Verify DDR3L 1.35V support and UDIMM slots

Before ordering, confirm your motherboard accepts DDR3L memory at 1.35V and provides unbuffered DIMM slots. Standard DDR3 at 1.5V is not electrically compatible with this low-voltage module. Check the system manual for the maximum supported capacity per slot and the qualified vendor list to ensure the 1Rx8 configuration is accepted.

Fits 240-pin DDR3L server boards needing ECC

The module installs directly into any 240-pin DDR3L UDIMM slot wired for ECC operation. It adds 4GB of error-correcting capacity without requiring registered or buffered memory support. This leaves remaining slots free for additional identical modules to expand total system memory within the platform limits.

Questions about this item

What comes with the single 4GB DDR3L module and do I need any extra parts to install it?

The package contains one 4GB 240-pin DDR3L ECC UDIMM rated at 1600MHz PC3L-12800 CL11 1.35V. No additional components are required; the module fits directly into a compatible DDR3 DIMM slot.

Should I choose this 4GB 1Rx8 DDR3L 1600MHz stick or look for a different capacity or rank?

This module provides 4GB in a single-rank 1Rx8 configuration at 1600MHz with 1.35V low voltage. Select it when your server or workstation needs a 4GB ECC unbuffered DIMM matching the IBM-Lenovo 00D5011, 0C19499 or 03T7802 part numbers.

What does the 1600MHz PC3L-12800 rating mean for actual throughput once the module is installed?

The 1600MHz PC3L-12800 specification indicates a peak transfer rate of 12800 MB/s at CL11 latency when the system runs the memory at its rated DDR3L 1600 speed.
