A-Tech 8GB DDR4 3200 ECC SODIMM

This 8GB DDR4 3200MHz ECC SODIMM is built for laptops, microservers and workstations that require error-correcting memory. It arrives as a single 260-pin unbuffered module running at 1.20V with a CL22 latency rating. The stick is a direct replacement for the Samsung M474A1K43DB1-CWE part number.

Suits ECC-capable mobile and microserver platforms

Systems that do not support ECC unbuffered SO-DIMMs cannot use this module. Buyers who need non-ECC memory for standard consumer laptops should look elsewhere. Platforms limited to lower DDR4 speeds will down-clock the module but it will not add ECC functionality where the chipset lacks it.

260-pin DDR4 SO-DIMM with ECC unbuffered design

The 260-pin DDR4 SO-DIMM form factor and ECC unbuffered architecture are the single specification that decides fit. Verify that your system expressly supports ECC unbuffered SO-DIMMs before ordering.

Questions about this item

Will this 260-pin DDR4 SODIMM fit the SODIMM slots on my laptop or microserver?

This module uses the 260-pin DDR4 SO-DIMM form factor, so it fits systems that accept 260-pin DDR4 SO-DIMM memory.

Can I add this ECC unbuffered stick alongside non-ECC memory already in my system?

ECC unbuffered and non-ECC modules are generally not compatible in the same system; the platform must support ECC for this stick to function correctly.

How can I confirm the module is running at 3200 MHz with CL22 timings after installation?

Check the memory speed and CAS latency in your BIOS or a system-information tool such as CPU-Z to verify 3200 MHz and CL22 operation.
