Hi. I have a weird af problem... I'm switching to ECC UDIMMs on a b550m motherboard
But only one stick is detected at a time. I have tried different slots and both work individually but together it still only shows 16gb in BIOS.
The really strange thing is that I plugged in a 3rd stick of non ECC and it read 48gb... So it detected all 3 then.
When I don't think it should have even been able to post with mixed UDIMM and DIMMs.
