I'd check your power cables to ensure they are fuly seated and the pcie cables, clean em a bit if you have to.

PG189 Turing core with 32G of gddr6
They can be bought from 150-400 usd.
Not sure if it works, but if it does it could be cheaper vs V100, and maybe faster if its full die.

I dont think there is 32GB memory on that single module. from what I can find, these came from the Nvidia Drive Pegasus system which used two of these together for a total of 32GB, 16GB each.
dont think they make GDDR6 in anything larger than 16Gb/2GB modules. this looks to have 8 of them on the SXM2 module, 8x2 = 16GB
these don't have very good performance. much lower memory bandwidth than a V100, much less FP64 performance (if you care about that). probably on par with something like a RTX 2070

Quadro rtx 8000 has 48gb vram, so it is possible for a 256 bit bus to have 32gb. They might be using clamshell memory.
RTX 8000 has 24x 2GB ram modules. 12 on the front and 12 on the back.
the Turing SXM2 module only has 8x
It would seem that you are right. What's more, they are 8gb modules?

I thought there might be two more memory chips under the bracket on the left and right of the core?
but I have seen some advertised as 8GB and some 16GB.
Yes. 8 chips x 16 x 2 = 256 bit bus. Module capacity is advertised for 256 bits, so 8gb total capacity.
