You're looking for a magical unicorn, and has probably been resolved multiple times over the years. As stated by others, keep the cards to a maximum of a GeForce 4, or Radeon 8500. If you want to play with newer graphics cards, invest in an i815 or newer motherboard. Radeon 95xx/9600/9700/9800's don't support 3.3V signalling, that's why it won't work.

Friend, your statements are not correct and you missed the point of the topic.
But I appreciate your contribution.

Yeah, Radeon 9700 and 9800, at least the ATI built ones, work just fine in 3.3v slots. Tested my 9800 Pro in several Slot 1 BX boards without issue.

Radeon 9500 and 9700 support 3.3V AGP . Radeon 9550 and 9600 do not . Some of the earlier Radeon 9800 support 3.3V AGP , but newer ones do not (depends on whether the card is R350 or R360 based ) .

Everyone's gotta be a wiki and full of hearsay, hence why I don't post here that much. C'est la vie.

Correct,
I may be unlucky with a correctly keyed 9800 pro that has no 3.3v support.
In any case, a Quadro FX3000 is on its way.

If you are referring to my last comment about AGP voltage , I would like to point out that what I wrote is corroborated by http://www.playtool.com/pages/agpcompat/agp.html , which is the very link that you yourself posted but who's information about "Radeon 95xx/9600/9700/9800" AGP voltage you contradicted in that same post of yours .

I don't really care. I done with the arrogance being displayed on this site. Adios. The link was used to inform him of why certain graphics cards won't work, not as a means to be placed on a pedestal.

Friend,
Please realize that you were the one who made statements even about my intentions.
Don't be angry if someone at least corrects you.
My post was about theoretical capabilities, not about balanced system.
And we all are pretty expert in what to put in a slot with a certain chipset regarding a VGA.

So linking "AGP for sticklers"... Well...

Let's say it is not appropriate here.

No pun intended and feel free to share your personal experience with 440bx.

It is not my intention to, so to speak, pour gasoline on a fire, but please consider that

a) I have personally used a Radeon 9700 in a 440BX board (Asus P3B-F most recently) and I can confirm that it works just fine with 3.3V AGP (albeit running at AGP 1x is required in my setup for stability, but that is a different issue). I also recall testing, a long time ago, a Radeon 9800 variant that was properly keyed for 3.3V AGP and posted fine in a 440BX board and worked in DOS (did not doe any Windows testing at the time).

b) If someone links to a site while contracting the information it presents, it is hardly unexpected that someone will point it out . EDIT : This should not be taken personally, as it is, IMHO, a perfectly normal reaction to contradictory information .

c) It is a bit confusing for me that you complain about "hearsay" when that is essentially what our experiences (yours, mine and everyone else's included) are to others . We all read, formulate hypotheses, run tests, take measurements and eventually come to conclusions which we share online. Some of us may be more methodological than others but, in the end, no one is impervious to making erroneous assumptions or making mistakes . Exchanging about our findings, experiences and reference materials is how we all learn, correct misconceptions and eventually (hopefully) come to some kind of consensus . I don't expect anyone to believe everything I write without question and also believe that I am right in applying the same analytical and critical perspective to what others write .

I am saddened to read that you were somehow offended by previous exchanges, but I really do not understand where you see arrogance in all this .

That said, you are obviously under no obligation explain yourself. If, however, you do choose to do so constructively, it is my hope that any ill will, perceived or otherwise, and any hard feelings will be put to rest . If you choose to simply leave, as you suggest you will, I extend my best wishes to you in pursuit of your retro interests , wherever they may take you .

Cheers and no hard feelings on my end .

Darry

Alright, to end this, assuming everyone here is an expert and knows exactly the topic, the conclusions appear to be:

- 440BX can handle anything properly keyed and 3.3v compliant.

- Properly keyed VGAs are not guaranteed to be 3.3v compliant (see my 9800pro)

- HSI chip CAN work at 3.3v, but there are issues at driver level (port or VGA side, more likely vga) that prevents correct communication, so we see arctifacts in 3D.

- The most powerful vga that can be used out of the box without mods or limitations (so using 133mhz FSB) is the nv35.

- Experience with Galaxy 6800xt or "mild" modded (blank plastic removed for 3.3v)Asus nv40 is appreciated.

- Remains to be seen if a NV40 card can be modded even if it has no blank spot on the agp port (without electrical traces of course). @J'AWS you can help maybe in that department.

Feel free to integrate.

I personally killed two working ASUS V9999 cards by cutting this slot on the connecor. They won't start anymore neither in AGP 2x neither AGP 4x/8x slot.
Now I dont wanna try my luck anymore cutting a good 6800Ultra. So it will stay not for 2x board. 😀

Thank you Cbb.
You mean a cut on a pcb same as the picture?
Or a cut on blank pcb spot like v9999ge ones?

FYI, a 7 year old thread with my 6800GT running at AGP 2x on a 440BX:

Re: Would this mod to this Geforce 6800 from AGP 1.5v to 3.3v kill it?

Newer than 6 series involved messing with AGP GART drivers, of which there are various. This is something I didn't document when I tested a 7 series at AGP 2x.

Interesting thread.

In my experience, the graphics performance with this class hardware was almost entirely CPU bound already, considering GPUs from the same time, or later.
Going for later video cards will bring little gain. Get the best CPUs instead.

At least i don't see significant improvement with the bunch of later video cards that i tried.

----

I confirm that GeForce 6800 GT/Ultra works well with modded AGP connector.
For example this fancy SDI version of Quadro FX4000 which is the pro equivalent of GF 6800 Ultra works just fine - https://www.petershipkov.com/temp/retro_pc_im … adro_fx4000.jpg

Depends on how much you crank up resolution and other quality features. Although that would be very specific scenario, i.e. if you need 2 or more ISA slots and most powerful AGP card available in one system, but you can't afford or find Pentium 4 ISA motherboards.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Agreed.
We can find many scenarios that don't fit my generalization.
I also find this thread a bit irrational, but considering the spirit of VOGONS, which is all about irrationality (the most positive meaning of it), then irrational + irrational = irrational, everything fits right in. 😁

If I need to be rational, I would never try 95% of what I try to do with oldware.
