problem rendering

No matter how small the part is (phisical size and number offeatures) when I try to render I always get this message "TheSolidWorks model is too large to be rendered".
I have disabled Indirect Illumination, Caustics and GlobalIllumination.
I have lowered options for Image Quality and set for betterPerformance.
What is the problem?

Thanks for any suggestions
