For some extra testing, I removed the AGP Voodoo 5500, and reinstalled the AGP FX 5200. Now, how can I overclock this thing, just to see what it can do?
There's a win98 software application installed called "Expert Tool", which allows you to increase the FX 5200's core clock (both 3D and 2D), and also its memory clock. Curiously, there's also a set of jumpers on the mobo [Epox EP-8KTA3PRO, PCB Rev 1.0] that allows you to mess about with the mobo's AGP voltage. Currently, this jumper is set to its default setting of +0.0V. I can remove this jumper, and place it on either the +0.1V, +0.2V, +0.3V, or +0.4V jumper. Presumably this will "overclock" the AGP port. Is it worth trying?
I attempted to overclock the FX 5200 card last night by using the Expert Tool application. I timidly increased the core clock to 277 mhz (from its default setting of 250 mhz), and I also increased the memory clock to 344 mhz (from its default setting of 280 mhz). Then, I ran glQuake in "1280/16 mode", and got 75.0 fps using the "timedemo demo2" console command. (Without this overclocking, the score is about 10% less at 70 fps.) However, this overclocking using Expert Tool seemed to make very little difference to my win98 pcpbench results. (I got 249 instead of my typical score of 247.)
So, do I continue to increase the overclocking values inside the Expert Tool utility, or should I alter the mobo's AGP voltage jumper, or do both perhaps?
If it all goes wrong, I may end up by accidentally "killing it with fire", which was leileilol's suggestion. 😉
