A-Tech 4GB DDR3 1600MHz ECC UDIMM

This 4GB DDR3 1600MHz ECC UDIMM module from A-Tech is built for server and workstation systems requiring error-correcting unbuffered memory. It operates at PC3-12800 speed with CL11 latency and standard 1.5V voltage. The 2Rx8 dual-rank organisation uses major-brand chips on a 240-pin DIMM form factor.

Suits ECC-capable servers needing 4GB DDR3 upgrades

Administrators upgrading or repairing platforms that accept DDR3 ECC unbuffered DIMMs at 1600MHz will find this module a direct replacement for Samsung M391B5273CH0-CK0 and M391B5273DH0-CK0 part numbers. Systems that require registered or load-reduced memory, or that only support non-ECC consumer modules, cannot use this part.

DDR3 1600MHz ECC unbuffered specification

The decisive attribute is the DDR3 1600MHz ECC unbuffered interface combined with 2Rx8 organisation. Your motherboard and CPU must explicitly support DDR3 ECC UDIMM at this speed and rank configuration; otherwise the module will not function. Verify the platform's qualified-vendor list before ordering.

Questions sur cet article

Does my motherboard need a 240-pin DDR3 slot to use this ECC UDIMM?

Yes, this module is a 240-pin DDR3 DIMM that requires a matching DDR3 UDIMM slot on the motherboard.

Will this 2Rx8 CL11 module run correctly if I keep my existing 1Rx8 CL9 sticks installed?

The system will default to the slowest common speed and latency; mixing ranks and timings can work but may reduce stability.

How can I confirm the module is operating at 1600 MHz with ECC active after installation?

Check the BIOS memory information or use a tool like CPU-Z to verify the reported speed of 1600 MHz and that ECC is shown as enabled.
