I did a video comparing the PCX1 and PCX2 which might interest you guys.

Do we know if PC 3D Engine runs at 60 MHz? I always wondered if there is a crystal beneath the heatsink.

I have a PCX1 as well, but the heatsink is soldered to the board, and I've never gone through the trouble to remove it.

Yes I believe there is a crystal under the heatsink.

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.

Made a small PowerVR Machine (PowerVR PCX2 based) from a MSI Desktop base.
It includes a 810 based motherboard, a Matrox M3D, 256MB 133MHz and a 1GHz Coppermine. Pimped with a PowerVR sticker and a slot-in Pioneer DVD reader. It's running cool and silent with WinME.
For now it's running with a SATA controller (SI 3512) on a 2.5" disk but I might migrate on a CF card. The freed PCI slot might be used either for a better primary card to be paired with a PowerVR (Tseng ET6000 or ATi Rage LT Pro PCI) or an exhaust PCI fan below the M3D card.

Thanks.
And thank you for your help about overclocking. This one uses my untouched M3D rev. B and I'll put the overclocked Videologic one (when it's done) in a well cooled tower. Still unsure about if it will be an AT or ATX though.

It gets extremely hot when overclocked. So be very generous with the cooling. Some kind of airflow is highly recommended.

Even at stock clocks i can barely touch it. I'll make sure it's cooled properly.

Guys I'm about to make benchmarks again with different primary cards.
Tests will include Dethkarz, Quake II, Half Life and Unreal. Considering Nascar Heat.
How do I turn off v-sync for HL ?

Can you please share the background ? Thx!
