iMac 27 doesn't boot with 4 Ram slots filled
Hi all,
iMac 27 2019. Trying to upgrade with installing the identical 2x4GB Ram modules (OEM Apple) to the 2 available slots. Followed the instructions from apple support but the iMac won't boot up after.
The iMac will boot up though with the 3 out of 4 modules installed, regardless of slot combination installed (not slot damaged) or modules combination (not module damaged).
All four modules are same (Apple 4GB OEM pre installed on iMac 2019).
Can anyone help me?
it doesn't make sense :)
