V5 Mac - Desktop freezes

[DarkRaven]

Hi!
I bought the v5 at an auction on ebay. This card came from usa yesterday. I put it into my computer and flashed it with the 1.18 bios at first. I used it as secondary card. After switching i cant believe my eyes: the desktop froze. As primary its the same problem. Then i thought it is a bios problem and flashed it back to 1.16. I tried it as primary again: the card works for ~10sec. After resizing a window the desktop froze again.
Does somebody have an idea? I'm very thankful for advices!!!

maybe you have an unstable system or the motherboard you have has symptoms, unless the flash failed I surely hope not.

@ DarkRaven
What's your machine ?
can you try the V5 in an other machine ?

[DarkRaven]

But if the flashing failed, i could put an other flash vers on the card, or do you mean the card didnt go along with the bios flash to pc version?

lol, nearly posted in the same time
my machine:
OS : win2k
Driver: tested with sfft35 und amigamerlin 3.1 r11
Others:
amd athlon 2400+
asrock k7s8xe
512 mb ddr 333 ram
other graphic card: ati radeon 9800Se
soundkarte: fortissimo 2
yep i have the chance to try it in another system, a good friend adviced me also to test it in another system thx für advice
but its interesting, why does the card work with 1.16 for more seconds in primary than in 1.18?

make sure you set "boot from pci" in your BIOS.my voodoo5mac (v4/5pci as well) locks up the very same way unless I do that.

hey ps47
im writing this text while my v5 mac is running. its interesting, the v5 works without problems when i do not use graphic drivers! i installed sfft35 drivers changed to 1280x1024@32 bit and opened trillian: when the pop up of trillian was shown the desktop froze again . i changed agp -> pci in bios. Any ideas?

ehm, no problem if 640x480 and 16 colors ?

[DarkRaven]

yep, if you use standard vga without drivers the v5 works without problems. But who wants to work in 640x480@16colors ? very strange

Did the card eventually flash with the pc bios? You mentioned that you tried ver. 1.16 as well, but that is not for the MAC/DVI version. The only bios is the special one ver. 1.18.

[DarkRaven]

how do you mean that? "card flash with the pc bios"? i first tried out 1.18 with DVI support, then 1.16.
i think 1.16 should work on a MAC too, but without DVI, doesnt it?

[Mikulaish]

Probably it should. You said: "But if the flashing failed, i could put an other flash vers on the card, or do you mean the card didnt go along with the bios flash to pc version?" , so i thought the card didnt't even flash. If it did flash, then it surely flashed correctly. And in the second case i am quite sure that it is a hardware issue, that can not be fixed. Sorry.

Maybe the second gpu is damaged? Standart drivers utilize only the first gpu..

[Nightbird]

Same idea here
Try to run the V5 in mode "Single chip only"

Try to use the V5 card in another machine and see whether it will froze or not.
