Yes, SpeedRamsey is indeed twiddling the skip bit. That ~18% increase looks right; IIRC the skip feature reduces memory access time from 5 to 4 cycles (-20%).
I doubt you would see anywhere near 18%...

The A314 works by 'replacing'/extending physical ram in the machine with its own internal memory. Thus you will get the most out of it by disabling motherboard ram and let the A314 handle all of it.
