G400 & OpenGL

[G400SG16mb]

I disabled it because it locks up within a minute if it is enabled.

Well I've got it in a different computer now, and it still locks up if bus mastering is enabled. Is it posible the card has some hardware fault that prevents bus mastering from being enabled? Or might there be some bug in the latest drivers that causes this problem with Windows Me?

did you install the latest chipset drivers? (including GART)?

I haven't heard of faulty G400s that lock up when busmastering is enabled, but you never know. I think in most (all?) cases the lockup is caused because of software issue or a faulty motherboard

latest drivers are installed. It *used* to work. It also doesn't work on a separate slot 1 computer. I think it's a fault with the card, although this motherboard is pretty flakey by itself.

[G400SG16mb]

Yes, I'm pretty sure it's just some bizzare hardware fault.

Use the MGAtweak utility to force AGP1x, see how it does.

Also, make sure you have a good connection to the AGP slot. Poor fit has caused problems like this for some people.

Hey all, is there still that motherboard bug where AGP Aperture should be set to 32MB? My memory is slowly coming back on this stuff.

[G400SG16mb]

hmm I believe I had it at AGP 2x with large aperture back when it was working, but I'll give it a try...

The Matrox Technical support Tweak Utility's option to set the driver to run at AGP 1x doesn't work. Changing the AGP aperture to a small size also doesn't work. I think it is a faulty card.
