- No, I found out that this phenomem happens when the clock is higher than 47

- Yes, that is the way it happens to me to.

- Hm, I think not as I have the same card. Try setting the MEMCLOCK variable in
- Cybervison/MEMCLOCK directory to 50 or 55.

- Yes, I have the same board. What is new about that trio chip from the old one?
- It looks the same as the old one :-(
