I have made this discovery already long years ago on my system,but due to lack of time I never got any reasonable explanation,so here is a short background.
When I succesfully upgraded my Asus TX97-X rev 1.02 mosfets for a higher load to be able to run AMD K6-III, I end that a setup 6x75Mhz was the highest stable seting,that I could run here (83FSB seems not supported by the PLL in this revision).Later on I moved to K6-III+ which I clocked with the same settings,but noticed in certain tools (MPXPlay example) which are able to show CPU usage,that show approx 3% higher CPU usage.The mobo has an updated BIOS to fully support K6 and the K6 DOS optimization tools which I run @ startup remain same setting,but Im not 100% sure if K6-III+ needed something extra right now.
Any idea what this small performance drop could be made of? One fact is that the K6-III+ is represented for 100FSB only altough it does run on lower FSB aswell.
