It is my understanding the 800 MHz Sonnet G4 is designed to drop the B & W bus
speed to 66 MHz. It is supplied with a set jumper block. One reason this
upgrade was not very popular.
When I finally do the upgrade I could use my own jumper shunts and try
different settings to find out if that would improve performance. --glen
