4GB DDR3 1600 ECC UDIMM for Synology

This 4GB DDR3 1600 ECC UDIMM module is designed for server and workstation systems requiring error-correcting memory. It serves as a direct replacement for the Synology RAMEC1600DDR3-4GBX2 part, using major-brand chips tested for dependable operation at standard 1.5V voltage.

240-pin DIMM installs in standard UDIMM slots

Installation follows the normal DIMM procedure: align the 240-pin module with the keyed slot, press down until the retention clips engage, and confirm the system recognises the capacity at POST. Common issues arise when mixing this unbuffered ECC stick with registered modules or when the platform does not support ECC UDIMM at 1600MHz CL11 timings.

Verify your system accepts DDR3 ECC UDIMM

Before ordering, confirm the motherboard or NAS documentation specifies support for DDR3 1600MHz PC3-12800 ECC unbuffered DIMMs at 1.5V with 1Rx8 organisation. Systems limited to non-ECC memory or registered DIMMs will not operate correctly with this module.

Questions sur cet article

How can I confirm the module is running at DDR3 1600 with CL11 after installation?

Enter the BIOS or use a system information tool to verify the memory reports 1600 MHz speed and CL11 latency at 1.5V.

What comes with the 4GB DDR3 ECC UDIMM and what must be sourced separately?

The box contains one 4GB 240-pin DDR3 1600 ECC UDIMM module; any additional DIMMs or installation tools are not included.

Which capacity and rank should I choose for a system that supports single-rank ECC UDIMMs?

Select the 4GB 1Rx8 version; it matches the single-rank ECC unbuffered specification required by compatible platforms.
