V6/V8 Pixel Clock Issues
The first generation of VPro boards (V6 & V8) have a design flaw that prohibits graphics modes in much of what might otherwise be considered the normal range for SGI desktop systems:
- Modes in the 109-193MHz range cannot be selected at all on V6/V8.
- Modes that are close to the lower end of that range (like 1280x1024_59/60) are only allowed at 8 bytes/pixel framebuffer size and even at that setting some people reported display problems (noise, flickering).
