URGENTE COMPATIBILITà MATROX G400 ASROCK K7S41

[thebastard]

Salve.
Grazie anticipatamente a quanti risponderanno a questo post.
Ho un dubbio di compatibilità tra una scheda video ed una M/B.
La scheda video è una vecchia (ma sempre buona) Matrox Millenium G400 series mentre la scheda madre è una AsRock K7S41 nella cui porta Agp c'è scritto "Please do not usea 3.3V Agp Card".
La Matrox è compatibile o no?
Grazie

Quella della G400 è una questione delicata ho trovato questa discussione, dipende in pratica dalla revisione della tua G400 l'ultima revisione "4A" numero di modello supporta in pieno AGP4X quindi 1,5V..

"The "full" G400 designed for AGP4x (1.5volt) slots has a 4A in the model
number (on the matrox sticker on the card itself).

All G400 are capable of voltage switching between 3.3 volts and 1.5 volts.

But you don't necessarily need a G400 with 4A in the model number to work in
in an AGP 4x board. The earlier model G400's will work in some AGP4X
motherboards. It depends on the motherboard (more info below).

Matrox realised they had made a mistake with the circuitry on the
original G400's and revised the circuit board even before the model 4A cards
were issued.

There are at least 3 different types of G400 cards:

TYPE 1) the original G400's 2x

TYPE 2) the revised G400's 2x with revised circuit board number (002 I
think)

TYPE 3) the "full" G400 4x cards (with 4A in model number)

I have a Gigabyte 8IRXP and an Asus P4B533-E. Both of these boards are for
AGP4x 1.5v
cards only. The difference between these motherboards is that the 8IRXP does
not attempt to save itself if a 3.3volts video card is inserted. ie. the
motherboard will burn itself out. The Asus P4B533-E actually checks the
video card
type inserted into the motherboard and will NOT boot with a 3.3volt card.

Now the TYPE 1 cards are detected by motherboards as 3.3volt - so the TYPE 1
card works okay in an 8IRXP (because the 8IRXP does not check the video card
type) but
the TYPE 1 cards won't work in a P4B533 (because the motherboard thinks
its 3.3volt card, but of course its not, because it will switch to 1.5volt)

The TYPE 2 cards will work in any motherboard looking for an AGP 4x 1.5v
card

The TYPE 3 cards will work in any motherboard looking for an AGP 4x 1.5v
card

Because of the auto voltage switching you can insert any Matrox G400 into
any motherboard with takes an AGP 4x 1.5v card and you will not burn it out."

Grazie per la risposta.
Ma i dubbi rimangono in quanto non so dove cercare il numero di serie della scheda, non avendo più la scatola.
Non posso nemmeno rischiare di mettere su la scheda perchè non credo che la K7s41 abbia un sistema di auto checking e blocchi una scheda Agp a 3.3v
hai qualche idea o consiglio?

il numero del modello deve essere stampato anche sulla scheda, prova a cercare tra le varie sigle....

sembrerebbe di tipo 2

quel 002....
ma non posso essere certo al 100%
