Review on OWC 2400MHZ SO DIMM PC4 19200 OWC2400DDR4S4GB by Marcus Munoz

UPDATE: After returning the product and getting a replacement, the replacement works fine. - Original Review - Tried to put them in each install slot the iMac 27" 2017 did not turn on during installation. Came back and tried a replacement again believing the problem was unique to that particular set. If the following set does not work, it should NOT be advertised as compatible with the 2017 27" iMac. ::cross your fingers::
