Okey, Just to prove this works, I have included 2 AIBB modules, the first is from my a3000 when I had the 50mhz FPU hack installed. This also proves that it works also. The second is with the entire motherboard running at 33mhz. Note that the graphics are running from a retina z3 4M board, so don't compare these, except for some FPU effect on GFX.
