Skylake Starter Guide
Another small issue is my memory (screenshot attached):
System Report lists 5 banks, though, naturally, the motherboard has only 4, as correctly shown in Clover Configurator. Seems to be an SMBIOS issue?
(I meant slots, not banks.)
OK ... figured out the mistake:
In Clover plist I wrote 4 entries for the RAM slots, starting with "1" ending on "4".
But as the first slot has to be "0" (and the last one "3") the OS just adds the "0" as empty, resulting in showing 5 slots.
ANYHOW:
Since upgrading from two to four RAM sticks, the mainboard keeps showing "Error Code 51" (Memory Initialization Error) from an early stage at boot onwards, remaining there afterwards.
Nevertheless, everything works fine, and memtest shows no errors.
Trying to get rid of this, I switched to "X.M.P. Profile" for Memory in UEFI, which resulted in a total failure of boot. I not even could get into UEFI anymore, had to remove two of the sticks and change the value to "Auto" back.
Changing the sticks around makes no difference – always the same boot failure.
The whole issue seems weird to me ... RAM seems to be healthy, motherboard, too, and there are no observable issues. But that resisting error code 51 drives me mad ... doesn't look "clean" on my always open case ...
