So that was pretty much it for my overclocking adventure! These are the specifications for the PowerGene MX videocard:

CMX2A Specifications

-Graphics Engine NVIDIA® GeForce2 MX™ -256-bit GPU Graphics Architecture -Onboard Memory 64MB of SDR Memory -Integrated high speed 350MHz RAMDAC -AGP 4X with Fast Write -350 million Peak Fill Rate (Pixels/Sec). -20 million Triangles Per Second (Peak Rate). -3D Rendering Pipelines. -Texture-Mapped, Lit Pixels Per Clock Cycle. -Single Pass Multi-Texturing Support. -Transform & Lighting Engine Second Generation. -Render with Geometry. -Complete DirectX 7 Support. -100% Hardware Triangle Setup. -Cubic Environment Mapping in Hardware.

-Texture Blend Support. * Advanced Texture Filtering * Per-pixel lighting and shading * Projective Textures * Procedural Textures * Texture Modulation * Light and reflection maps * DXTC Texture compression * Bump Mapping -Backend Blend. -Per Pixel Perspective Correct Texture Mapping. -Full Scene, Order Independent Anti-Aliasing Z-Buffer. -Stencil Buffer. -Hardware Acceleration (Windows GDI). -Fast 32-Bit VGA/SVGA Support. -Multi-Buffering. -Video Acceleration (DirectShow, MPEG-1, MPEG-2, Indeo). -X & Y Smooth Up and Down Scaling with Filtering. -Per-Pixel Color Keying. -Hardware Color Space Conversion/Filtering YUV 4:2:2 and 4:2:0. -VESA DDC2B + DPMS. -Support for TV-out feature option.

It's easy to spot the lower theoretical fill rate for this card. 350 MPixels/s designates a slower GPU clock speed (175x2= 350).
