The solid block is due to how rainmeter works to auto-scale the non-percentual values. To fix add the following code to the measure (probably "MeasureCPU"), with suitable numbers for your computer and usage:



MinValue=

MaxValue=



It will probably remain like this since everyone's computer is different. Mine usually does 500-700 MHz just sitting there, so maybe min 400 and max 1200 is good for me.
