4GB DDR3 1333 ECC UDIMM for servers

This 4GB DDR3 1333 ECC UDIMM module is built for servers and workstations that require error-correcting unbuffered memory. It operates at PC3-10600 speed with CL9 latency and standard 1.5V voltage. The single 240-pin DIMM uses a 2Rx8 organisation and major-brand chips. It serves as a direct replacement for the listed Hynix part numbers.

Simple DIMM installation with ECC verification

Installation follows standard DDR3 DIMM procedure: power down, open the chassis, align the notch on the 240-pin edge connector, and press firmly until the retention clips lock. The module is unbuffered, so no register timing adjustments are needed. The most common issue is a motherboard that disables ECC in the BIOS or requires matched pairs for multi-channel operation, which a single stick cannot satisfy.

Verify DDR3 ECC UDIMM support before ordering

Confirm that your system accepts DDR3 ECC unbuffered DIMMs at 1333 MHz and 1.5V. Check the maximum capacity per slot and the total number of 240-pin slots available. Ensure the platform supports 2Rx8 rank organisation and does not require registered or load-reduced modules. Buyers needing higher densities, registered ECC, or a different DDR generation should look elsewhere.

Preguntas sobre este artículo

How can I confirm the module is running at 1333 MHz with ECC after installation?

Check the system BIOS or UEFI to verify the reported speed and ECC status, then run a memory diagnostic tool to validate stability.

What comes in the box and do I need any extra parts to install this memory?

The package includes one 4GB DDR3 1333 ECC UDIMM module; no additional components are required for installation in a compatible 240-pin DIMM slot.

Which version should I choose if my server uses Hynix HMT351U7AFR8C-H9 modules?

This A-Tech 4GB DDR3 1333 ECC UDIMM 2Rx8 1.5V module is a compatible equivalent for Hynix HMT351U7AFR8C-H9, HMT351U7BFR8C-H9, HMT351U7CFR8C-H9, and HMT351U7EFR8C-H9.
