Server DDR3 ECC UDIMM

This 4 GB DDR3 1600 MHz ECC unbuffered DIMM is built for servers and workstations that require error-correcting memory. It runs at 1.5 V with CL11 latency and uses a 1Rx8 Samsung chipset on a 240-pin module.

Compatibility fit

It suits administrators replacing a Samsung M391B5173QH0-CK0 module or adding ECC capacity to a DDR3 platform that accepts unbuffered DIMMs. Builders needing registered memory, higher density modules, or a newer DDR generation should look elsewhere.

Installation notes

The module installs like any standard DDR3 DIMM: align the notch, press until the latches click, and verify the system recognises the full capacity. The most common issue is mixing registered and unbuffered DIMMs, which prevents the server from posting.

Questions sur cet article

Does this 240-pin DDR3 UDIMM fit a motherboard with DDR3 1.50V slots?

Yes, the module is a 240-pin DDR3 UDIMM rated at 1.50V, matching standard DDR3 DIMM sockets that operate at 1.5V.

Will this CL11 1Rx8 stick run in a server that already has CL9 2Rx4 modules?

The module runs at DDR3 1600 with CL11 timing; the system will typically down-clock all sticks to the slowest common speed and latency.

How can I confirm the 4GB module is detected as ECC UDIMM at 1600 MHz after install?

Check the BIOS memory info or run a tool such as dmidecode or CPU-Z; it should report 4GB, DDR3 1600, ECC unbuffered, 1Rx8.
