If any of you got that same card working, please let us know how/on what hardware

In one of Phil's videos, were he is mounting a fan on a Compaq V3 3500 model.
He is having it running on a Gigabyte GA-5AX, wich indecates that it should run on Ali-V chipset's
On the screamer2 video, he is using the same motherboard, and a V3-3500.
Wich I suspect that it may also be the Compaq model.

We really need Phil to give some info, if he had any issues, and what exact hardware he was using.
I think we are missing some vital info regarding why the cards are working internally,
yet not having any vga signal at all.

Hi!

Sorry I didn't have this issue. I used the V3 in the Gigabyte GA-5AX as well as in the AOpen AX6BC.

Wich is really strange, that some Compaq 3500's have issues on other 440BX boards and other Ali-V boards.
Thanks for the info Phil. I can report that it is not a power issue eighter.
I have tried with both a 300watt PSU and a 400watt PSU. Need to see if the cards really are faulty or not.

EDIT:
Could it be, that the firmware has some motherboard lockout incorporated in the code?
Based on the manufactor's name. Just wondering if that is the problem. Hmmm...
Because when I have the Voodoo as the second card (intializes pci first), and when Windows loads the
drivers. Then the card will send small flashes out onto the VGA-Output.
It is not enough to drive the monitor, so it just turns on for a fraction of a second.

Yet the driver is telling the card to turn on, so it must be somewhere in the firmware or a faulty RAMDAC.
Because as fast as the drivers turn the card on, when they load, just as fast is there something that is
"telling" the VGA out to shut down. As I wrote in a previous post, the rest of the computer works 100%
as it should, as no error beeps occour, the boot process is good and Windows loads fine.
In other words. Nothing out of the ordinaery, other than the missing signal on the VGA-Output.

No, the Compaq V3 3500 (and V3 1000 too) work just fine in all AGP 2x compatible boards.

Some do not. The Compaq-3500 model exactly. Some does work like the one Phil's got.
It has been running on both Ali-V based boards and 440BX based board.
I have read on a website, that on some systems (EX, FX and LX chipsets) all V3's just crashes.
Can't be certain at this, because I have not seen or heard that anywhere else.

EDIT: (found the site again)
This page: http://jfeelder.home.xs4all.nl/voodoousers/tr … otherboard.html
Some early SS7 boards just burn out, because of the Voltage regulator issue.
Even though they are perfectly AGPx2 compliant boards. Wich you could buy HW fixes for back then.
I am namely thinking of the FIC-PA2013 board, when someone just burned a hole through the board.

Well, socket 7 AGP is always problematic and the whole platform is way to slow to run Voodoo3 at its full potential anyway.

I believe this particular V3 is pretty much the same as any other V3 AGP int the MB compatibility issue. Many years ago I have experienced serious problems running Voodoo3 2000 and 3000 AGP on Asus P3B-F... but apart from that I can't remember any other compatibility troubles.

How fast FSB can the V3 take at most. 100mhz or 133mhz?
If the limit is 100mhz, then it's no big deal, as both my P3-500 and my K6-III-400 are 100mhz systems.

FSB speed doesn't really matter as long as there is correct AGP divider used. Default AGP clock is 66 MHz.
i440BX/ZX supports 1/1 and 2/3 dividers - they are meant for the 66MHz FSB and 100MHz respectively (in both cases AGP will run at 66 MHz). 133MHz FSB on 440BX results in AGP going at 89 MHz and that can be to much to handle for some VGAs. Usually the Voodoo3 works just fine even with overclocked AGP... but of course it is possible not all of them can do it.

Super Socket 7 chipsets have the 2/3 divider as well. Just be careful - some boards have separate jumper for AGP clock and it needs to be set correctly.

Thanks... So 66mhz AGP is just fine then. 😀
The boards that I have, are running at 66mhz AGP.

I think that I found the specs for the original Compaq computer that the 3500 card came from.
Compaq Presario 7950. The V3-1000 was sold in the 5000 series. Not the V3-3500.

All right... Have been working with the card a bit.

After some flashing of the BIOS/Firmware, and leaving the PCI gfx card in the slot to boot on.
I am beginning to get 4 beep codes (1 long and 3 short), when Windows starts to initialize the Voodoo as the second card.

Some googling, reveals that it is the system that can not access the GFX memory.
On some reboots (every 25 to 30 time), the Voodoo comes on for about 30 seconds and then it dies.
No matter how much I flash there is no progress beyon this point.
Even cleaning the "contacts" on the card does not seem to solve anything.

EDIT:
Shure enough... After some minutes, the card turns on.
It is as if the Voodoo just need some time to heat up, or something like that.
Does anyone know what I should look for now?

What platform are you using?
There is a TUSL2-C on its way. I will test the card and tell you if I had success 😀

Bad solder joints?

Tested the card on my P5A with K6-3-400 and PC100 ram, plus my Intel VC-820 with an P3-500 and PC800 ram.
I even borrowed a friends Aopen (can't remember model, someting x and 6) with P3-800 and 440bx chipset.

Same exact result every time.

Does not seem that way. All the solder-joints look good.
Nothing is corroded or cracked.

I even contacted the local tv/computer/radio repair man today. Asking for an aprox' price on recapping those 6 cap's.
He told me that he could not tell the exact price. Well... It was at least 70 us dollars, perhaps even at much as 128.
Caps included. Now I can't stop wondering if I can do it my self. As the V3-3500c is not worth THAT much.

It is a rare graphics card, not super duper rare, but rare.

There may be hairline cracks, which are invisible, and especially under the BGA GPU which won't be visible at all unless you happen to have an x-ray machine.

Well... Only the rarest of the rarest pc-part are rare enough for an x-ray. This card is way too common for that. 😁
So basically, I am kind of stuck for now. I can only get closer to solving the issue, if someone knows what exactly to look for and why.
Perhaps a way to identify a possible bad component, other than walking in the blind.
I do not have any fancy tools or machines, only a soldering iron and the most common soldering tools.

Pretty shure that I can de-solder those caps, when I get to some tools in one way or another.
I am just missing those values, as I am not used to reading stuff the way it's printed on these cap's

The 6 cap's have the following written on them:
-
10
16s
9F8
-
What are these rating's?

I am positive that I can do it, using the approach in this video.
Look's so damn easy btw.

That's 10µF 16V. But I really doubt it's a capacitor problem. You're saying it starts working after a while, but caps usually get worse when they warm up.
If you have hot air gun, preheater and IR thermometer, I would try reflowing the GPU first.
