Frequently asked questions (FAQ)

Can I install old celeron PPGA CPU on SV25?

No! FV25 mainboard is Universal platform which supports Tualatin / Celeron-T CPU, due to differences in pin assignments, installing celeron PPGA CPU can permanently damage both CPU and mainboard.

When using TV-Out, the resolution is unclear or fuzzy on TV but regular CRT monitor is fine

The causes are lies in design and features differences between TV and CRT monitor.
1. In general, 17" CRT monitor with 0.27 mm dot pitch for crystal clear images, but TV is not the case. It has only horizontal line distance-to-distance.
2. CRT monitor supports high resolution & refresh rate. But on the other hand, TV has only low scan line.
3. CRT monitor and TVs' Video's amplify specification is different

What is the maximum resolution for SV25 when TV-Out is in use?

The maximum is 800*600 and it is the specification of TV-Out chipset.
