I have an iMac 5K 2019 where I’ve replaced the stock RAM with two plates 8GB (2666MHz) each (HyperX HX426S15IB2K2/16).
Today I bought two more ''identical'' modules and tried to install them. So now I have 4 identical modules. But my iMac didn’t start. I can only feel that warm air is coming from the iMac, but nothing more: the screen is black.
I’ve tried next configurations:
* It '''boots''' with any single module installed in any slot;
* It '''boots''' with any two modules installed in slots 1+3 or 2+4;
* But it '''doesn’t boot''' with any two modules installed in 1+2 or 3+4 slots;
* It also '''doesn’t boot''' with any thee modules installed in any thee slots
-
So I think, that modules are ok, and the slots are also ok. So what could be the problem?
