A-Tech 16GB DDR5 4800 ECC UDIMM

This 16GB DDR5 module runs at 4800 MHz with CL40 latency and 1.10V operation. It targets server and workstation builders who need error-correcting memory for data integrity. The unbuffered design fits standard desktop-style DIMM slots in compatible platforms.

Samsung chipset replacement with lifetime coverage

A-Tech validates each stick as a compatible equivalent to the Samsung M324R2GA3BB0-CQK part number. Quality assurance testing and a lifetime warranty back the module, while US-based technical support assists with installation and troubleshooting.

288-pin DDR5 DIMM with 1Rx8 organisation

The module uses a 288-pin DDR5 form factor and single-rank 1Rx8 (EC4) layout for broad motherboard compatibility. Unbuffered ECC operation requires a platform that explicitly supports ECC UDIMMs; systems without that support cannot use the error-correction feature.

Questions about this item

Will the ECC function on this 1Rx8 module require any periodic maintenance or replacement?

No, the ECC logic is built into the Samsung chipset on the 1Rx8 module and operates automatically; there are no user-serviceable parts or scheduled replacements for the error-correction function.

What limit appears first when this DDR5 4800 CL40 stick runs at full load for hours?

The CAS latency of CL40 and the fixed 4800 MT/s data rate set the timing boundary; sustained throughput cannot exceed the JEDEC DDR5 4800 specification.

How much heat and power does a single 16 GB 1.10 V DDR5 DIMM produce in a server running 24/7?

At the standard 1.10 V DDR5 voltage the module draws only the power required for 4800 MT/s operation; typical power dissipation stays within the low envelope defined for unbuffered DDR5 UDIMMs.
