From what it sounds like the motherboard may be unable to supply enough Amperage through the AGP slot. I know this was a common issue on AGP systems in that transition period between AT and ATX formats with some Slot 1 motherboards and Super 7. If you have anything older on hand and less powerful, like a Geforce 2 mx, TNT, or something like that give it a try and see if you have the same issues.

yes i have tested it with an Elsa Erazor III (AGP, riva TNT2 based) and an ASUS AGP-V7100 (AGP, Nvidia Geforce 2 MX based) both work witout problems.

couldnt i just solder a wire onto the AGP slot or onto the Card itself to support the AGP current directly from PSU? Has anyone done this?

I am no expert, but I think the issue there would be regulation. IIRC the technical issue is the chip that regulates/supplies voltage to the AGP slot does not supply enough Amperage, bypassing that regulating circuitry completely I think you would end up frying the video card at the least, possibly the motherboard as well.

Yea thats what im afraid of. The guy in the Link above did this tho. You can read it up here http://www.xbitlabs.com/articles/graphics/dis … owercons_3.html
This really sucks 🙁

Very interesting solution. I will say that with a Slot 1 motherboard you are pretty cpu limited anyways, so you arent missing out on much using a slower card.

I agree on a Slot 1 system you'd do just fine with say a Ti 500 or Radeon 8500

I agree here! Even a Ti200 or Radeon 7500 would be solid. Geforce 3 ti200's are really cheap and easy to find. Save those 9800's for faster machines that can fully utilize them 😀 heck, those cards are getting pretty rare in working shape anyways. They have a bad tendency of running hot and burning up.

OK ill put the GF2 MX back in 🙁
Thanks for all the help anyways, Vogons is great!

Any time! Iv been filling out job apps all day so this has been open in a tab. Some nice relief from the monotony.

An AT motherboard with AGP slot must have an onboard voltage regulator for the AGP slot to provide 3.3V as the AT standard doesn't supply it. I guess the regulator is too weak for your 9800 SE.
Also some early AGP equipped ATX boards had an onboard regulator for the AGP slot, like the Asus P2L97. Mine couldn't handle a GeForce DDR, the system crashed when the driver loaded.

I've made the AGP mod with the help of Matze79 on my GA-6ba for more current and still had issues with the MX440 freezing in Grandia2 and Toca2. After I installed the Radeon 9200se the 3dmark99 results were around 49xx instead of 5115 from the Nvidia but the PC doesn't seem to freeze anymore and even with shadows enabled Grandia2 runs smooth.

It has a floppy drive power connector so it draws current directly from the power supply, besides from the AGP slot.

Guess I'm missing something but should not the motherboard be out of the game if the graphics card has its own dedicated power cable?
Just saying, because everybody kept discussing the motherboard's capabilities?

Also, for the late AT era, 55 Watt of anything is a f*ckton of power consumption.
That's roughly the time when the first fans appeared on VGA cards, huh?

So, if not for the floppy connector bypass, the motherboard should be utterly incapable of supplying that kind of juice.
Only the full blown AGP Pro was supposed to handle more than 50 Watts:

Pretty sure what killed our parent's first Slot A mobo was my brother's humble Geforce 256 and that thing's TDP doesn't even register.
(Motherboard was a cheap M7MKE one from Biostar, though.)

So, it will not work without the bypass and it might not work with it because the Card does something with it that the board can't handle and/or which leads to strange effecs on the PSU. My theory. Switching PSUs are strange sometimes.

Well, sorry, I also think you should just call it a day and go with something less of a room heating implement. 😉

Only just realized that this is a zombie thread.

But, for what it worth, OP has two 350 W PSU, so they're probably ATX. Board takes both.
And I don't think using a AT one would have made any difference. But does the board need to be jumpered accordingly?

Rev 3 has separate jumpers for more current like Voodoo3 cards need but mine for example is rev 2.5
Besides I use a brand new EVGA BR ATX PSU with 450W.
