AGP bus speed = more vid card heat.

I am running a 146 mhz FSB on a Shuttle AK35GTR. I have not tested extensively, but my cpu seems ok at this speed. However, after a few hours of typing last night I noticed that I was getting graphic anomolies in 2d apps. I realized the foolishness of typing stuff on a machine that had not been thouroughly tested at its OC'ed speed, turned it off, let it cool for half an hour and then went back to work after resetting everything at default. All was fine...

I suspect that my voodoo 5, which has the factory heatsinks on it and never overclocked worth a damn, just got heat loaded at the high agp bus and started to flake out.

Does this seem like a reasonable theory?

(No, I can't tell you what my agp divider is, I am at my office....)

Thanks

FSB overclocking automatically overclocks everything in your system: CPU, memory, PCI, AGP.
Some of the very latest mobos have an option to leave the PCI bus at a selectable fixed speed, not sure if this also keeps the AGP at fixed speed, one of them is the P4 mobo Abit BD7.

I had a Voodoo 5 for a few days and that thing was a furnace !! Your AGP bus is 1/2 of your CPU bus speed, so 73 is the # if you're running at 146 which shouldn't be a prob for most graphix cards. Not sure about that V5 tho.
