Is that an overclocking device of some sort?

Spectrum Engineering rings a bell, oh yea they did the design for the Quadra 950 upgrade I have (68040/50mhz + 128K cache).

Look at the yellow writing on the top of the CPU.

So can you run a test program to see if anything runs faster? IS the RAM that works by chance faster then the ram that does not?
