I have a NAS with a 3rd gen i7 and 8 GB (2x 4GB DDR3 1600 MHz) of non-ECC RAM which has a RAID 5 mdadm array. I don’t have any memory issues but I could as I add more services. I have two other 4 GB sticks 1333 MHz DDR3 which I have no other use for. I don’t care about the minor speed decrease. I know mixing is generally a bad idea.
But, all of the posts I’ve seen about this are in regard to playing games or in production environments with server-grade hardware (ECC RAM, maybe hardware RAID). Not in a consumer hardware-focused homelab-type environment
What do you all think? Has anyone else done something similar? Am I asking for trouble here?
Mixing RAM is OK. I’ve been running consumer PCs with mixed memory for years.
Better not put different sticks on the same channel, though. Depending on your MB you may need to set frequency manually to 1333, but most likely it will work without that.
I’ve done it for old scrappy machines in the past, but IMO it’s all down to how good the BIOS is…
Most should downrate to the slowest RAM speed… you might need to manually set the speed, but… it should work.
My biggest concern was the RAID I didnt even think of the bios. I might test short term and see how it goes. Thanks!
