16 GB DDR4 upgrade for Acer Aspire

This 16 GB DDR4 module is built for Acer Aspire AXC-780-UR16, TC-780-UR15 and ATC-780A-UR12 desktops. It installs as a single 288-pin DIMM in one of the two available slots. The memory runs at 2133 MHz with CL15 timing at 1.2 V. It is a non-ECC, unbuffered stick suited for everyday productivity workloads.

Capacity headroom for dual-slot systems

The kit provides 16 GB in a single rank 2Rx8 configuration, leaving the second slot free for a matching module. The platform maximum is 32 GB, so a second 16 GB stick completes the supported capacity. Performance scales with dual-channel operation when both slots are populated. Single-channel bandwidth is adequate for office tasks but limits memory-intensive workloads.

Standard voltage operation without a heat spreader

The module operates at the standard 1.2 V DDR4 voltage and has no heat spreader. Under typical desktop loads it runs within JEDEC thermal limits using passive airflow alone. Acoustic output is negligible because there are no active cooling components. Power draw remains low, consistent with mainstream DDR4 DIMMs at this frequency.

Questions about this item

Will this 288-pin DDR4 2133MHz module work with the existing memory in my Acer Aspire AXC-780-UR16?

Yes, the module is validated for the AXC-780-UR16 which supports up to 32GB across two sockets; adding this 16GB stick alongside a compatible DDR4 DIMM will operate at the system's supported speed.

How can I verify the CL15 timing is active after installing the CM2048642133DIMM?

Enter the BIOS or use a system-information utility such as CPU-Z; the memory tab should report 2133MHz frequency with 15-15-15 timings at 1.2V for the installed module.

Does the package include only the 16GB memory stick or are any tools or cables supplied?

The box contains one 288-pin DDR4 DIMM; no installation tools, cables or additional hardware are included.
