marvel g400 and bussmastering on aopen ax59pro

[kjliew]

If you're experiencing instability even in normal 2D operations, I am suspecting that you may have an old revision of AX59Pro. The revision of your mobo is a crucial clue to your problem. But just FYI, AX59Pro is one of the best MVP3 mobos only if you get the right revision. How many L2 cache the mobo has?? If you have 1MB or more, that's a good one. If 512K, you'll need to look for the VT82C598 to find out if it's "CD" or "CE".

Please let us know. There's no point to go further without the info of your mobo.

the MB reision is 1,31
L2 cache 512k
VT82C598 is CD

That explains well of all my predictions.

Matrox AGP implementation is very aggressive. Your MVP3 revision CD is quite buggy in AGP. It has been well known that MVP3 revision CD and earlier will not work with any AGP 2x cards.

Make sure you have Matrox MTSUtils to force AGP 1x all the time. In addition, you may like to try disable AGP 2x by installing VIA AGP driver in NORMAL mode. Latest VIA AGP driver have an option to turn off AGP sideband as well. Play with them.

Too bad, your mobo turns out to be the real problem. Frankly speaking I can't be sure if forcing AGP 1x will free you from all stability problems. MVP3 revision CD and earlier are not meant to be used with any 2nd generation AGP cards. Even Intel740 is not guaranteed to work well. AGP cards that work well are those 1st generation AGP cards such as Riva128, perhaps ATI RAGE Rro and Matrox G100. Or any AGP cards in PCI flavor, such as Millenium II AGP, S3 Virge/GX and all 3Dfx AGP cards.

If things turn out doesn't help at all, perhaps you would like to consider a mobo upgrade. SS7 mobo are really cheap now.

thanks too all

hnelson,

With respect to kjliew, who is quite correct about stability problems with that chipset, I used to have one of those chipsets. I used to use it day in and day out with a G400 attatched to it, and it was considered one of the most horrible of all (an FIC VA503+). Using the steps I posted here, I was able to achieve quite good stability, and leave busmastering on. So please at least give it a shot, it has worked for me and (many) others. You may be able to use your motherboard until you can save up the extra cash for a good system upgrade (New motherboard, processor, some more memory, the works ).

I have had several VA503+ boards and never had a problem with busmastering with the G400. The G200 now that was an altogether different creature. I now (finally) have the G200 (the same one that I had sold to my brother) running in the same VA503+ with busmastering enabled, 4in1v25a and PD 6.04
