So this seems to use 6.144TiB as the limit that will fit in RAM. That's 1.536TiB x 4 when using the latest Xeon I could find[1]. According to the specs though you should be able to use 8, so the total limit should actually be 1.536 x 8 = 12.288 TiB. 12TiB of RAM, that's quite amazing.

It seemed to use 6.000000000000000444089209850...??? TiB when I tried values.

It seems to use different values of cutoff depending on if you are using MiB/GiB/TiB/etc. I tested with GiB and 6144 is OK, 6145 is not.

Glad to see I wasn't the only one to test the limits. ?
