Today I tried two Kyro II cards on overclocked 440BX's AGP slots.
Hercules' doesn't show anything at 124MHz
Powercolor's shows artifacts at 129MHz. 124MHz are fine.
These frequencies are FSB ones with 1:1 AGP frequency on a NMC 6BEX board.
Both tested in 3DMark 2001SE and Final Reality 5x. Not sure if doing long benchmarks is useful in this case. I know it is when overclocking chips but I don't know if it is with stock chip clocks but overclocked ports.
Question : can I damage a card with an overclocked AGP slot ? Voltage is untouched.
Powercolor's version is rather rare, I don't want to kill it.
Thanks.
