Hi,
I have repurposed a mac mini (mid 2011) that has 16gb of memory installed. Originally, Apple stated that this machine would only work with 8gb max memory, however, it was discovered that it would work fine with 2x8gb memory modules. Under OSX, the system reports 16gb of memory.
Booted into Majaro 20.2 running under kernel 5.9.3-1, both DIMMs are being reported as 4gb. I have tried pulling each in turn and they each show as 4gb. These are both Cosair CMSA8GX3M2A1333C9 8gb 1.333mhz CL9 DDR3 So-DImms (Double checked)
As noted, I have removed and replaced the DIMMs and this is not an issue that one DIMM is not working and therefore only showing 8Gb because one DIMM is faulty. Both slots show 4Gb.
I would appreciate if someone could advise anything that I can do to get both DIMMs reported correctly with a total of 16Gb of memory.
For assistance, some data dumps:
