What this memory is and who it fits

This 16 GB DDR4 DIMM runs at 2666 MHz with CL19 timings and 1.20 V. It is a single 288-pin unbuffered non-ECC module built for Acer Aspire TC-860, TC-865, TC-866 and TC-885 desktops. The kit contains one stick.

Check your board before ordering

The system supports a maximum of 32 GB across two DIMM slots. Verify you have a free slot and that the current module, if any, is also DDR4 2666 MHz so speeds stay matched. A 64-bit operating system is required to use more than 4 GB.

Suits single-slot upgrades on listed Acers

Ideal for owners of the named Acer models who want to add 16 GB in one slot. Not for systems that need ECC or registered memory, for boards limited to lower speeds, or for builds requiring a matched pair to reach 32 GB in dual-channel mode.

Questions about this item

What comes in the box and do I need to buy anything else to install this 16GB DDR4 2666MHz DIMM?

The box contains one 16GB 288-pin DDR4 2666MHz CL19 2Rx8 1.2V unbuffered non-ECC DIMM. No extra parts or tools are required for installation in a compatible Acer Aspire desktop.

My Acer Aspire TC-885 has two slots and supports up to 32GB — should I buy one 16GB module or two?

For maximum performance on the dual-channel TC-885, install two 16GB modules to reach the 32GB limit; a single 16GB module works but runs in single-channel mode.

The module is rated 2666MHz CL19 — what speed will it actually run at in my Aspire TC-860?

It will operate at 2666MHz with 19-19-19 timings at 1.2V, provided the CPU and motherboard support that frequency; otherwise it downclocks to the highest supported speed.
