Quick question. This is my bench/test/fun to overclock computer:

AMD K6-2 450, oc'd for a time to 500
SOYO SY 5EMA+ v 1.1, bus speeds from 66 to 100, 112,124
96mb PC-100 SDRAM, generic
Voodoo3 2000 AGP
One 10gig 5400RPM Maxtor UDMA 66
One 2gig 5400RPM Seagate UDMA 33
Linksys Ethernet card
ESS Generic sound
CD-ROM 50x etc

It is hooked up to a Belkin OmniCube 2 port KVM switch, F1do92, connected to a P3-450, 128mb RAM, Voodoo3 3000

Built this system last weekend. Ran great and stable at 500mhz on the soyo mobo. Would not overclock beyond that. Whenever I set the bus speed to 112x5 (560), the screen would not come up on boot. So I was content at 100x5, 500mhz. System ran great for 3 days straight, no reboots, running SETI.

Tried once again Monday at 112x4.5. System would not boot up again, no screen at all. Ran it at 500mhz again, played some games via the belkin switcher.

Immediately after trying this, all went to hell. Windows would boot, but would lock up constantly after 5-10 minutes. In addition, when it locked up, or during normal operation, strange dots/lines/drawings would appear on the screen. I thought it might be the switch, so I plugged it in directly to my computer. Still no dice. After playing with some components, I realized it was the video card.

It seems the video card failed. When I swapped the 2000 with the 3000 from my Pentium computer, windows ran fine for over 2 hours. When I swapped it back, I got the same strange dots and lines and such.

My question: Could I have damaged this video card by briefly running the bus at 112mhz? Or could it have been damaged by playing a game at 5x100 through the Belkin switcher? The manual says that at 112mhz, the AGP bus is running at about 75mhz. The card worked fine before I started playing with the bus speed and playing games with the Belkin attached. The card however, did not work very well at all and crashed my system even when I dropped the processor to its standard 4.5x100 (and swapped RAM, other peripherals. BTW, all other PCI devices still work fine). Or could it be that the video card suffered infant mortality and just broke after 3 days of usage? What do you all think?

I've been running my voodoo3 2000 on a 110mhz bus for a few months now with it over clocked to 175mhz so I think you just got a bad card send it back and get a replacement http://www.sysopt.com/forum/smile.gif also make sure you add a fan to the card when you get the new on the run really hot and when you start pushing them with high bus speeds etc etc the tend not to like it very much with out some extra cooling http://www.sysopt.com/forum/smile.gif

I was just going to say the same thing. Voodoo cards tend to run very hot - do not neglect the cooling on them.
