A-Tech 4GB DDR3L 1600 ECC RDIMM 2Rx8 1.35V server RAM

4GB DDR3L 1600 ECC RDIMM

This 4GB registered ECC module runs at DDR3L 1600 (PC3L-12800) with a CAS latency of CL11 and a low operating voltage of 1.35V. It is built for server and workstation platforms that require registered DIMMs with error-correcting code. The single 2Rx8 rank stick fits 240-pin DDR3 slots.

Registered 240-pin build with major-brand chips

The registered design places a buffer on the command and address lines to reduce electrical load on the memory controller, which helps stability in multi-DIMM server configurations. Major-brand DRAM chips are used throughout and each module undergoes quality-assurance testing before shipment. The 1.35V DDR3L voltage lowers power draw compared with standard 1.5V DDR3 while remaining compatible with slots that accept low-voltage modules.

Direct replacement for IBM-Lenovo 46W0735 0C19533

This module matches the part numbers 46W0735, 0C19533 and 46W0692, making it a drop-in upgrade for compatible IBM-Lenovo systems. The jump is worth it when a server or workstation shows sluggish multitasking, frequent paging or memory-related errors that ECC can correct. Buyers who need non-ECC unbuffered memory for consumer desktops or laptops should look elsewhere.
