  • ECC protection prevents data corruption in critical workloads
  • 2V JEDEC standard voltage reduces power draw

  • 260-pin SO-DIMM form factor fits laptop and microserver slots
  • CL19 latency at 2666 MHz delivers responsive multitasking

8GB DDR4 2666 ECC SODIMM for microservers

This A-Tech module provides 8GB of DDR4 memory at 2666 MHz with ECC error correction. It uses the 260-pin SO-DIMM form factor and runs at the standard 1.2V JEDEC voltage. The single-rank 1Rx8 design targets systems that require unbuffered ECC memory for data integrity.

Suited for ECC-capable laptops.

Buyers whose platforms do not support ECC unbuffered SODIMMs cannot use this module. It is not for systems limited to non-ECC memory or those requiring registered DIMMs. The fixed CL19 latency and 2666 MHz speed also exclude builds that demand higher frequencies or lower timings.

Handles typical multitasking

The single module fills one slot, leaving room for expansion if the board has additional sockets. Capacity runs out when workloads exceed 8GB, such as large virtualisation sets or heavy database caches. ECC protection covers single-bit errors but does not increase the physical memory ceiling.

Questions about this item

My laptop only has one SO-DIMM slot — will this single 8 GB 260-pin module work on its own?

Yes, the module is a single 8 GB stick with a 260-pin DDR4 SO-DIMM form factor, so it installs in one slot and provides the full capacity without needing a matched pair.

I plan to keep my existing non-ECC DDR4 stick — what happens when I add this 1Rx8 ECC module?

Mixing ECC and non-ECC memory typically disables error correction on both modules, and the system will run at the lower of the two speeds with the looser timing.

After installing the module, how can I confirm the ECC function is actually active?

Enter the BIOS or UEFI and look for an ECC status line showing enabled, or run a system-information tool that reports ECC capability as active for the installed memory.
