Hello,

Can anyone please recommend RAM that is confirmed to work properly in a late-2015 iMac 27"? I tried to install 2x8GB G.Skill 1866 MHz memory, and it resulted in all the memory (including the 2 factory Apple sticks) being clocked down to 1600 MHz. When I removed the G.Skill sticks, the factory sticks went back up to the proper 1867 MHz. Not sure what to try next; 1867-MHz DDR3 SO-DIMMs are difficult to find locally, and I don't want to blindly try different ones until I eventually find one that works...

Thanks
