Hi,

Here picture when sli is enabled.

...

I was talking with Hank about this problem and he told me the probem can  come from 2, 3 or 4 chip, probably there is a memory issue and chip never returns back and holds all the chip back.

So, the way would be to have a good tool to isolate the failure and check command registers  and see what chip fail.

Any tip?

Note- I was thinking if could be possible to change via HW or SW the master VSA-100 chip and run de card in single mode.

Best regards,
Oscar.

I have a stupid question:

Do the VSA100 render the screen sequentially?

I mean, from top to bottom:

1st VSA100 - 1st row
2nd VSA100 - 2nd row
3rd VSA100 - 3rd row
4th VSA100 - 4th row


..and then again from the beginning..

If it was so easy, I'd say the second chip seems to be affected in some way, no?

Memory sounds possible to me too. Chip 2, 3 and 4 have been changed, so these should be good.

I noticed a similar behavior of the image of my 5500 with a defective memory on the second VSA100.

It would be nice to know how the signaling between the VSA100 works, like goriath wrote. Maybe it is possible to deactivate/unsolder one of the slave VSA100 and the V6k works with 2 or 3 chips only. This way we could identify the defective memory cluster and would only have to change those.

Yes, it could be but check the picture. If second vsa-100 is the blue row and  it is sequential. The space between blue rows should be more width since that the second row blue would correspond to the first vsa-100 now.

It should be
1
blue
3
4
1
blue

But for the image seems:
1
blue
3
4
Blue

About memory, I have noticied different artifacts when one tsop is in bad condiction though.

ps. Perhaps in the bios is set the master chip. it would be the best way to check each vsa-100 in single mode.

Regards,
Oscar.

Oh well, this is really a good point.

A Voodoo5 5500 with a physical damage to the second VSA can still work. The system sees half of the card, like it was a V4 4500.

I was thinking we have a PCI2PCI Bridge device involved; dunno how this could affect the test. BTW it's a good idea.

Honestly, at the beginning I thought the same. But actually paying more attention to the image, it looks like the space between two blue rows is too much for being like that, but also too little for being like I said.

Oh well, I can't say, it's too difficult only looking at picture. It was only a supposition.

EDIT: BTW, still looking at picture. If we are assuming that the first black row is a single row rendered by the first VSA, the last black row at the bottom is wider than the first row on top, but thinner than the rows between the blue ones. So that would suggest:


2° - (blue)



2° - (blue)
...
...
2° - (blue)

4° (since it has to end even)

So, each VSA renders 12 rows. It also depends by the resolution...is there no way to know what res the card was attempt to run?

EDIT: I'm trying to figure out if could be plausuble. Assuming 1024x768 res, it should look like this: http://img40.imageshack.us/img40/3668/v56ksli.png

Yes, 1024x768.

Anyway I will try to take better picture. It was taken with the iphone. LoL

So it looks like a problem with the second VSA100. A shot in the dark, just change the memory cluster that leads to the second VSA100.

Hi Radu,

Nope, when card launchs a 3D application the image is like I showed above.

It is time to reemplace the tsops and master vsa-100.

I keep you informed.

Best regards,
Oscar.

I have a hunch Smiley
