Acer Aspire DDR4 memory kit

This 32 GB kit uses two 16 GB DDR4 DIMMs that run at 2666 MHz with CL19 timings. The modules are 288-pin unbuffered non-ECC parts rated at 1.20 V and use a 2Rx8 organisation. They are validated for the Acer Aspire TC-860, TC-865, TC-866 and TC-885 desktops. The matched pair fills both available sockets for the platform maximum capacity.

Builders who need the full 32 GB

Owners of the listed Aspire towers who want the maximum supported memory will use both slots with this kit. Systems that require ECC or registered modules cannot use these DIMMs. Buyers needing more than 32 GB must choose a different platform. A 64-bit operating system is required to address the full capacity.

Sustained operation at rated speed

The modules operate at the standard 1.20 V without a heat spreader, relying on case airflow for cooling. Under continuous load they maintain the specified 2666 MHz frequency and 19-19-19 timings. All installed memory runs at the slowest module speed, so mixing with slower DIMMs will reduce performance.

Questions about this item

Does my Acer Aspire TC-860 need a 64-bit operating system to use the full 32GB capacity?

Yes, a 64-bit operating system is required to address more than 4GB of memory, allowing the full 32GB kit to be utilised.

If I keep one existing 16GB DDR4 2666 module and add this 2x16GB kit, what speed will the memory run at?

All installed modules will run at the slowest speed present; mixing with a matching 2666 MHz stick keeps the system at 2666 MHz.

How can I verify the kit is running at the rated 2666 MHz and CL19 timings after installation?

Check the memory speed and 19-19-19 timings in the BIOS or with a system-information tool such as CPU-Z once the PC boots.
