Hi all, Quick technical question... I've bought 16 GB of Crucial ram for my iMac... Installed it (removing the standard 2x 4 GB of Apple ram that was in there) and It only made beeps after I clicked the power button... Then, after a quick Google search I put back the Apple Ram in the first two slots, inserted the 2x 8 GB of Crucial ram in the upper two slots and now it works... with 24 GB.... (see screenshot) I’ve always thought mixing Ram GB-sizes and manufacturers was a bad thing. But this is the only config in which the iMac even boots up :S Isn’t this weird? Is there anything bad about having 24 GB of ram, mixed manufacturers the way I have it now? I thought it was all very strange… Any insight would be very appreciated... *PS. Wouldn't (in the screenshot) two times 8 GB on the first row, and 2x 4 GB on the second row be better/perform better? Or is this just my OCD acting up?
