System-specific DDR4 kit

This 32 GB kit contains two 16 GB DDR4 2400 modules rated at CL17 with 1.2 V unbuffered operation. It is built for the Acer Aspire ATC-780-AMZi5 and Aspire TC-780 desktops that use 288-pin DIMM slots.

Suited for maxing out supported memory

The kit fills both DIMM sockets to reach the platform maximum of 32 GB, ideal for owners of the listed Acer models who want the full supported capacity. Builders with different motherboards, laptops or systems requiring ECC or registered memory should look elsewhere.

Steady throughput at rated speed

Under sustained load the modules run at the specified 2400 MHz with 17-17-17 timings and 1.2 V, delivering consistent bandwidth without heat spreaders or higher-voltage profiles.

Questions about this item

My Acer Aspire ATC-780 has two DIMM slots — will this 32 GB kit fill both of them?

Yes, the kit contains two 16 GB DDR4 DIMMs and the ATC-780 has exactly two slots, so both slots will be occupied.

Can I keep one of the original 8 GB DDR4 sticks and add just one 16 GB module from this kit?

The kit is sold as a matched pair of 16 GB modules; mixing capacities or ranks can prevent the system from booting, so use both new sticks together.

After installing both modules, how do I confirm the system is running at 2400 MHz with CL17 timings?

Open Task Manager’s Performance tab or run CPU-Z; both should show 2400 MHz speed and 17-17-17 latency for the installed memory.
