Safe to mount a G400MAX on a i845D chipset?

Same here but mine does not work (MSI 845E)!

Success on an ASUS P4C800 Deluxe Board!!



Finally, last night, I moved on a brand new Asus P4C800 Deluxe Board. (AGP Pro 4x/8x, at 1,5V)

My problem was, obviously, that my old-rev G400Max does have the infamous problem on the TYPEDET# signal, and I decided finally tho short the R68 pin, before trying to mount the graphics board on (is a 906-1 Rev. A, surely incompatible).

Three minutes to have the soldering unit hot, three seconds to sold ensemble the two R68 pins (it's easy like to put a Jumper), and now my G400Max is working fine on the shiny new Asus Mobo.

Ironically, on the old original thread start I was asking for the compatibility with i845D Chipset, and now I maked it on the i875P !!!

Tanks to everyone have contributed, with precious informations, making possible for me to make this.

Thanks, thanks, thanks again.

Hi,

have 2 g400 2x AGP. I tried to get it work with a L7S7A2 Mobo (Elitegroup)

No chance. If the computer is cold, system boots normaly. But after one reboot, blank screen.

Also a g400 4x does not work.

So I took the 2x and bridged the R68 resistor. No changes.

Is it right, what I have done? I connectet the two silver points with a soldering iron and tin.

Look at the attachement, please.

Sorry, perhaps for you guys it is a stupid question.


Thank you

If G400 x4 doesn't work, there's no point in messing with resistor mod...try to get x4 working first (you might want to post on matrox tech support forum also)

[dZeus]

you sure it's caused by the G400? do other AGP videocards work without the cold restart behaviour? because it sounds more like a mobo or cpu problem to me.

[damy2]

I think it is a combination problem between the mobo and the g400. Now there is a nvidia card in the AGP slot, and it runs perfect.

But the g400 card works also perfect in a k7s75a Mobo. Like I said, it seems to be a combination problem. I postet it in the matrox forum, they do not know either.

But I want to buy a Pentium IV Mobo, where I want to install the G400 2x AGP. And if I need to make the modifikation at the R68 resistor, I need to know, if I do the right thing.

Is it correct to bridge the two little silver points with tin, like I did in the attachement picture? (Ok, in the attachement picture I used the option "clone" in my corel draw program to bridge them )

Thank you

Hi damy2,

I soldered directly the two 'R68' point with a fast touch
on the board with the solder iron.

Remember to touch the board with the solder iron fast
as you can (wait until it is hot, then make the fast pick)
in order to not damage the board.

If I remeber correctly, for me was not necessary to use
some soldering pond, effectively the pond already on the
board was sufficient.

An advice for you: if you are not very confident with
soldering activities, search for a friend that are capable
of doing it.

Byez.

I'm sure this thread is way past dead, but I'm so exited I got this to work I had to tell someone, even if it's just a computer!

I didn't like the idea of soldering on so small a scale, so I took 30 gauge magnet wire (radio shack), burned off the enamel, cleaned it up with steel wool, and put a piece into the R68 holes. I then put a piece of electrical tape down on the board, folded the wire down on top of it and then put another piece of tape over the wire. Fired it up, worked great.

I tried the pencil route without success.

btw, it's in an Intel D865GBF motherboard (i865G chipset) that would not recognize the unmodded Matrox card.

Thanks for all your help, where ever you might be now-a-days.

I recently upgraded my old media system (P3B-F + G400 Max) with a P4C800-E motherboard and a G450. But I was not satisfied with the RGB out and speed of the G450. I even tried the G550 but the newer cards are not as good as the G400 Max. And the G400 Max has DOS TV-OUT, which the newer cards don't have. Also, the card can simultaniously output composite and RGB.

I then plugged in the G400 Max but the system did not boot. It just took 10 seconds to close the R68 points with some solder, and the card now works fine !

Thanks to those who found this out, I'm still amazed with the TV OUT after all those years, there is nothing better than RGB from a G400 Max !
