Speccy 1.17.340 reports the following about my built-in Intel G45/G43 graphics processor:
Intel® G45/G43 Express Chipset

The processor, which I had to activate yesterday after my external video processor died, only has a measly 128MB shared RAM to work with, as far as I know.
The system has a total of 8gb RAM.
