Hi Chip! Without owning any R640s or R650s, my impression is that you will only be able to install a single slot GPU due to space limitations. There is a single slot Tesla with 24GB: Tesla A10 [1]. This will only fit if you have the R640/R650 version with full profile slots. But the biggest problem is the 8pin PCIe power connector on the A10. While the T4 does not have any additional power connectors, the A10 has an 8pin connector which must be connected for the card to work. And my guess would be that the R640/R650 have no easy way to supply the card with such an 8pin PCIe power connector. But there weem to exist adapters like:
