3D-games with G400. Problem

which would suggest that you're experiencing a busmastering problem (as OpenGL doesn't work without busmastering on the G4x0).

Get your motherboard manual, and check which PCI slot(s) is sharing an IRQ channel with the AGP slot. If there's a card in the slot that shares the IRQ channel, move it to a different slot.

btw. if you want to be sure if this problem is related to a busmastering issue, try DVD-MAX on a monitor or TV connected to your secondary output of your videocard.

Dzeus, What??
Try what??

I have read the manuel, and according to it, there shouldnt be any differences between the slot my SBlive occupied before, and the one I just moved it to yesterday.

BUT: Sofar, no crashes!

Still too early to break out the coffe and cake..

Ill keep You posted.

Yason, you mentioned "Only OpenGl games haves this problem..." Try changing maximum support of AGP4X to AGP2X in your bios.

When I updated from driver revision 5.31 to 5.51 for Win2K with service pack 1, my system would lock up immediately after I started an OpenGL application. Setting my bios to instruct the Via chipset to support a maximum of AGP2X cured the lockup problem.

Notes: you won't notice any performance lose, and I haven't checked if the problem still occurs with service pack 2, which I've already installed.

No such luck.
Moving my soundcard might have reduced the number of freezes, but definitely not eliminated them (havent done any ANOVA stat tests yet, but). Last freeze was with picture cooruption etc. Actually it looked like death due to overclocking (striped frozen screen). My G400MAX isnt overclocked, and Im currently running my 'puter without casing (due to some motherboard troubles, unrelated) - so heat shouldnt be a problem.

Sorry

"Striped frozen screen" definitely sounds like an AGP speed problem to me (I used to get this immediately on bootup under various flavors of Windows and using various drivers).

Along with Perseus' suggestion, or instead of it, you can try the Matrox Tweak Utility and force AGP 1x and see if that helps. If it works, you can try 2x (which might or might not work). But at least you'd have things working at 1x.

did you check the DVD-MAX feature yet, as I told you in my last post?

I'm experiencing the same problems...
My machine:

Athlon 600@666(6x111) [but the problem doesn't go away in 600MHz]
Microstar K7PRO
Matrox G400 Dualhead
SB Live! 1024
Asuscom ISDN card
Logithech Mousaman Wheel Optical USB
Aopen 1040Pro (DVD)
Plextor 12/10/32A
IBM Deskstar 30GB + Fujitsu 13.7 GB

The problems seems to appear in Win2K only. And freezes quite fast when running OpenGL, but it takes a little longer time to freeze in DirectX. OpenGL freezes looks ugly, like a rainbow or something. And in DirectX the last sound-sample often plays on...but when i took out the SB live! card, the problems didn't appear. I think all the stuff shares the same IRQ, since ASPI is enabled.

[Wiking]

I've fixed the IRQ's.

IRQ 9: Ethernet card
IRQ 10: USB Controller(USB mouse) and SB Live!1024
IRQ 11: ISDN Card and Matrox G400
IRQ 14: Futjitsu 13.7 GB
IRQ 15: IBM Deskstar 30 GB

But I still experience problems. For example; Serious Sam locked up after 15 min the last time I was playing.

[Wiking]

and...the only freeze I have until now were like, the picture freezes and the sound plays a loop(Counter-Strike[OpenGL and DirectX] and Serious Sam).

[Antlergoat]

I am experiencing the EXACT same problem

Im still reading through this massive thread, but wondering if someone has discovered a fix yet?

Thanks y'all

For the OpenGL crash.

For me only thing that fixed the problem was going back to the WHQL-drivers 5.32 ) but that did the trick for reason or another.. tried EVERY trick in the BOOK ( well atleast most of them )

( Well actually i had another problem where the pic was getting screwd up and computer still run fine, while i fixed that one i got this OpenGL freeze [ after about a minute after i run etc CS ].. so going back to 5.32 fixed both of those. ) So, if you still are having problems.. you might want to try this one out.. its easy and takes about 5 minutes.

Dont know why, but i NEVER could run these new drivers.. just hoping that when installing XP i can use the latest drivers with that.

But thats a new OS and another story... you might see a thread about it after next weekend. =)

WHQL-drivers 5.32

I had this problem in QIII, Unreal Tourn Diablo II in the Palace levelonly, and CS. I fixed this going back to WHQL-drivers 5.32. I was just hoping to have found another one with these new drivers. Mainly becasue the ICD is much more efficient. Anyhoot I did change my AGP memmory allotment in my system BIOS last night to 256mb and CS did't lock up at all. And that was playing for like 3 hours. I aslo turned off 32-bit Z buffer and turned off bus- mastering. Not sure which one of these fixed the CS locking problem but thats what I did.

Thansk all for your efforts.

[Wombat]

Turning off bus mastering probably stopped your lockups. But it's not an acceptable solution most of the time. You've really crippled your card's speed.

[Antlergoat]

Hmmm...



Thanks. That's actually helpful. Iam still locking in DiabloII but only when I go into the palace in Lut Goliehn. Strange for it only to do it in one spot in the game. Anyway, at least I'm playing CS again. Ill try specifically toggeling bus-master without changing anything else to see if directly related.
I can see a new mobo+chip+video card in my future.
