DELL AB257620 memory module 32 GB DDR4 3200 MHz:
Random Access Memory (RAM) is a type of hardware that your computer uses to store information. Adding memory space is one of the most cost-effective ways to improve your computer’s performance.
The memory currently available may have a different speed than the system’s original memory, but has been tested to work with the computer. If memories are mixed, the memory runs at the lowest frequency that any of them have, or the highest frequency that the computer can handle.
