Allan Posted November 14, 2017 Share Posted November 14, 2017 XMPDetection are set as Yes or No in your config.plist? And in your UEFIBIOS too. 1 Link to comment https://www.insanelymac.com/forum/topic/329639-bios-sees-16gb-but-osx-only-12gb-ram/#findComment-2534789 Share on other sites More sharing options...
Dan ZG Posted November 14, 2017 Author Share Posted November 14, 2017 It's not set at all in config.plist And by UEFIBIOS you mean in my BIOS settings? I would have to check. Should they both be enabled? thanks! 1 Link to comment https://www.insanelymac.com/forum/topic/329639-bios-sees-16gb-but-osx-only-12gb-ram/#findComment-2534815 Share on other sites More sharing options...

Dan ZG Posted November 14, 2017 Author Share Posted November 14, 2017 No XMP option in BIOS anywhere. Set XMP to Yes in config, but made no difference.

Allan Posted November 14, 2017 Share Posted November 14, 2017 Ok. Try this: https://clover-wiki.zetam.org/Configuration/SMBIOS#smbios_memory You need insert all your RAM slots, with correct speed, type and manufacturer.

Dan ZG Posted November 15, 2017 Author Share Posted November 15, 2017 Success! Opening the box led me to RTFM of the mobo ... and I discovered I had the 4 chips inserted wrongly. (It's a triple channel 6-slot board, and I was using the wrong slots.) I re-arranged them properly, and now I can see all 4x4. Thanks for all your help! 1 Link to comment https://www.insanelymac.com/forum/topic/329639-bios-sees-16gb-but-osx-only-12gb-ram/#findComment-2535028 Share on other sites More sharing options...
dreadkopp Posted November 15, 2017 Share Posted November 15, 2017 congrats. You should consider adding 2 more 4gb sticks though for tripple channel Link to comment https://www.insanelymac.com/forum/topic/329639-bios-sees-16gb-but-osx-only-12gb-ram/#findComment-2535047 Share on other sites More sharing options...
Dan ZG Posted November 15, 2017 Author Share Posted November 15, 2017 Thanks! Yeah, I'm on amazon now... But I'm wondering ... can I add 2x8GB? I've seen different reports about this mobo having or not having a maximum of 6x4GB. Some people report success with 6x8GB. Could I do 4x4GB + 2x8GB?
