voltages of g400/g200 cards...

[Hpar_]

the new boards like the nForce2 boards for example are 1.5v agp.
most of the new mainboards are 1.5v ONLY! it is a big problem for older videocards. I have the marvel g400 tv, a marvel g200 tv, a millenium g400 dual head card, and a couple of mystique 220's with rainbow runner addon. so what are the voltages of these video cards?

G400 and newer are 1.5/3.3v
Anything older is only 3.3v
And this (as well as your last couple threads) really belong in the Matrox Hardware forum. This forum is for Desktop Video editing issues.

The Marvel G200 is 3.3 volts (AGP 2x standard) only. I've heard mixed reports about whether the Marvel G400 supports AGP 4x 1.5 volts as well as 2x 3.3 volts. Personally I wouldn't count on it. Don't know about the others. If they're more than a year or two old then they are probably limited to AGP 2x 3.3v. If any of them are PCI cards then the AGP voltage isn't an issue.

I'm currently testing a Marvel G400 with the Abit KX7-333 Mobo (yeah, yeah, I know...VIA chipset. Don't nobody give me any grief, okay?) and TBSC sound card. I don't expect to be able to do any Huffyuv captures, so I'll have to rely mainly on the hardware mjpeg under win98. I'll miss out a little on the quality end there. But I'm hoping to make up for it with the dual-head output and on mpeg rendering times (AthlonXP 2000+ and 512 MB PC2100 RAM).

I chose this Abit mobo to test for a couple of reasons: first I was trying out the MSI 745 Ultra and I really liked the overall performance, but I was VERY unhappy with the Matrox G450 etv, as far as capture quality and options were concerned. I especially don't like the 2.x generation of Video Tools. The old 1.5x generation gave much better control (IMHO...maybe I'm just prejudiced). AVIIO worked okay, but dropped more frames than I liked. And I didn't like the video output on the All-In-Wonder card I tested. I couldn't capture in Premiere at all without at least 50% dropped frames. And sadly the RT line is simply out of my price range.

Unfortunately the MSI board wouldn't support my old G200 (despite it's limitations, I've been very happy with it) and I had doubts about the G400 I replaced it with, hence the Abit.

Sorry if I wandered a little off-topic there. Don't know if I answered your question or not!

[edit] Kruz thanx for confirming the G400 voltage for me.

yup. I just got off the phone with one of the techs at matrox. the matrox people are great; let me just say that now.... the g400marvel tv will work in a 1.5volt slot or a 3.3 volt slot. the g200marvel tv will not unless your board has one of those fancy universal 8x agp slots. in my opinion ALL new full sized workstation level mainboards, including the nforce2, kt333/kt400, and sis 745 boards should use the universal agp 8x slot. also he said the g400 millenium dual head card will not work. I have an oem version and it is only 3.3 volts which is fine. I have an older system that it will work with.

I am sorry about posting in the wrong forum.


also, the guy had just put together an asus a7v333 system for his gaming box. the system rocked is what he said. that is the board he recommended I get but he didnt know much about the nforce2 and according to the reviews are better boards.

all G400 boards support 1.5v as well as 3.3v. The first used PCB rev. just has some conflicts with certain motherboards which auto-detect the card's voltage, but those are solved easily.

he had me read off the exact model number and based on that he was able to chk the voltage. I guess some are 1.5/3.3 and others are only 3.3? I would think they are all both voltages g400 and beyond.
