Really useful thread. I have the same issue I have a CT16G4WFD824A specified by Amazon for a CT8374078 specified by the Crucial System Scanner my HPZ420 Xeon system (it also specifies CT7996301 and CT11003103). Clicking on another Crucial recommended RAM I get a CT16G4XFD824A selected by Amazon (this one is cheaper). Are they all the same and can I safely buy the CT16G4XFD824A?
System Scanner recommends a DDR4 PC4-19200 • CL=17 • Dual Ranked • x8 based • Unbuffered • ECC • DDR4-2400 • 1.2V • 2048Meg x 72
