I have a small update on my T5810 for future reference. My two sticks of DDR4 2400mhz ECC ram arrived. There was conflicting information on if it'll run with different sized ram installed but it does.
I have the two 8 gig 2400mhz (dual rank) sticks in slot 1 and 2 and the original 4 gig 2133mhz (single rank) sticks in 3 and 4 for a total of 24gig and it's running correctly in quad channel. The E5 2630 V3 6 core I have in it only runs ram at 1866mz so all 4 channels are running at 1866mhz. I got the dual rank 2400mhz sticks as the end goal with the machine is a high end E5 V4 Xeon and they run the ram at 2400mhz.
I'll add more 8 gig dual rank 2400mhz sticks soon.
