Hey guys,

I have an intellimouse optical - not sure if its a 1 or 1.1 version. It overclocks to 500hz stable max so I presume its a 1.1 but I did buy it years ago when it could possibly have been a mark 1?

Or is it only the WMO that has 2 versions one which sucks and the other that can do 1000hz? I have heard lots of debate about the sensor but I always thought the IMO had a different one to wmo 1.1a and IE3.
