Using Opera with other RAM devices

I have the original Opera Browser card and the expansion. But it has only 8MB.
Other expansion packs, like the EZ-V 3-in-1, have more than this.

So, if I use the Opera Browser (the original or the patched one) with these devices, would it use the whole memory available or only the 8MB from the original.
If possible, heavy sites would load faster?
