Possibly you're confusing BIOS option "UMA FRAME BUFFER SIZE" with the
actual amount of memory allocated to the GPU?

if you crank this down to 64Mb on a REVO, then NVIDIA-SETTINGS reports
256Mb available to the card (as does the Xorg.0.log file). Crank it up
to a buffer size of 256Mb results in 512Mb available to the GPU.

I don't has an Asrock 330 (too expensive for my taste), so can't comment
on that. You might however want to check what X or the nvidia-settings
application reports as available memory rather than just going by a
setting in the BIOS as the meaning of some BIOS settings can be a little
unclear.
