My AC97 onboard soundchip runs great on a 43MHz bus
It's a PCchips mobo in a BookPC. I use it to play DVDs occasionally - but it runs the Genome@Home client continuously. 28 days of uptime on Win98se running a Celeron2/700@878
The onboard 10/100 SIS 900 LAN chip is dead, however. It just stopped working one day. When I set the speed back to default (33), it still locked up the system. I tried everything. Finally, I was forced to buy a USB network adapter - which is working very well.
First component I ever fried (besides a hard drive) while running on an overclocked PCI bus. oh well.
