BIOS sees 16GB, but OSX only 12GB (RAM)

ram

Best Answer Dan ZG, 15 November 2017 - 10:39 AM

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!

XMPDetection are set as Yes or No in your config.plist?


And in your UEFIBIOS too.

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!

XMPDetection = Yes, No, 1, or 2?

No XMP option in BIOS anywhere.

Set XMP to Yes in config, but made no difference.

:(

Ok. Try this: https://clover-wiki....S#smbios_memory

You need insert all your RAM slots, with correct speed, type and manufacturer.

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?
