8GB DDR4 2666MHz DIMM for Acer Aspire

This 8GB DDR4 2666MHz CL19 unbuffered DIMM is built for Acer Aspire TC-860, TC-865, TC-866 and TC-885 desktops. It runs at 1.20V with 288-pin DDR4 SDRAM interface and 2Rx8 organisation. The module carries a limited lifetime warranty from Computer Memory Solutions.

Suits single-slot upgrades on supported Acer towers

Buyers adding memory to the listed Aspire models will find guaranteed compatibility. Systems already populated to the 32GB maximum across two sockets cannot accept this module. Users needing ECC or registered memory should look elsewhere.

Handles everyday workloads up to 32GB system limit

One stick provides 8GB capacity; the platform supports up to 32GB total across two slots. Installing matched pairs is recommended to maximise performance. A 64-bit operating system is required to address more than 4GB of memory.

Questions about this item

Does my Acer Aspire TC-865 need a free 288-pin DDR4 slot to install this 8GB module?

Yes, the Aspire TC-865 has two DDR4 DIMM slots and this stick occupies one of them.

Can I keep my existing 2666MHz DDR4 stick and add this CL19 2Rx8 module without changing BIOS settings?

The system will run all memory at the slowest installed speed, so mixing works but may lower overall throughput.

How do I confirm the new stick is recognised at 2666MHz after fitting it in my TC-885?

Open Task Manager or BIOS and check that total memory shows 8GB more and the reported speed reads 2666MHz.
