I see in that line that 4800 is the only speed listed as JEDEC (which means native speed). All the higher speeds require overclocking. I guess we'll need to test if overclocking works and is stable on a Thelio R3-- it does appear from internal conversations like we might have went with 4800 partially for pricing reasons, so it might work fine. Not sure if any default BIOS settings would need to be changed to enable overclocking (XMP, etc).

I'm not sure why we weren't offering the system with 128GB as a config option if it supported that. It looks like we're also offering less than the motherboard maximum for R4, but its motherboard vendor only says it supports up to 96GB. It could just be a product class thing.
