The iMac 27" 2019 (no matter which CPU) supports up to 128 GB RAM (4 x 32 GB RAM modules). It has 4 RAM slots, meaning 4 RAM modules in total will fit in. A higher total amount than 128 GB RAM won't work due to a limitation in the logic board.
The iMac 2019 needs RAM that matches the following specification:
PC4-21300 DDR4 2666 MHz, 260-pin
