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.

Questions about this item

What DDR3L speed and PC3L rating does this 4GB module run at?

This module operates at DDR3L 1600 with a PC3L 12800 rating, delivering 1600 MT/s bandwidth at 1.35V.

Will the 240-pin registered DIMM fit my server's memory slots?

The stick uses the standard 240-pin DDR3 DIMM form factor with registered signalling; it fits any DDR3 RDIMM slot that accepts 2Rx8 modules.

How do I install this ECC RDIMM and what step is often missed?

Power down, open the chassis, align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC and registered mode are enabled.
