This 16GB RAM is 100% compatible with the Fujitsu CELSIUS M720 power.

Information on memory configuration: The following technical specifications should be considered in advance: RDIMM memory modules cannot be mixed with ECC memory. If a memory upgrade is to be made with the existing RAM, it must be checked which memory technology (RDIMM / ECC) is present. Memory slots without a processor should not be populated. A higher memory clock of the memory module automatically adjusts to the memory clock specified by the system. This can especially be the case with larger capacities. Low Voltage memory with 1.35V will be clocked at 1.5V when mixed with 1.5V memory due to the fallback option available in the memory. There are 4 memory channels per CPU, each with 3 memory slots.
