    Hey all,

    Was just wondering if any of you clever geezers knew if there were any relatively new gfx cards that will happily run at AGP 2X

    Of course. :D

    Infact when Installed my ti4200 the manufacturers drivers reverted the bios settings to agp 2x, for compliability. I just needed to install the 4 in 1's drivers to fix it

    so what you're saying is that most new cards will run at AGP 2x, surely there is some sort of inpedence to the actual card as it is using a slower interface?

    How much slower do cards run like that? I'm interested as the new Radeons are 8x and my poor, poor mobo only supports 4x :cries:

    I went down to agp 1x and lost like 80 3dmark points so in other words: it hardly matters at all

    I apologise for bumping an older thread but I have a question. I also am looking for a card that is compatible with agp 2x. I emailed my mobo manufacturer and got a short cryptic reply:

    No, you can't use this AGP spec 2.0 card in this AGP spec 1.0 design motherboard. It might run but after a while it will stop because the 2.0 required 1.5v where our board doesn't have it.

    Now after a thorough search of both my owners manual and the supermicro site I cannot find any information on the voltage for the agp 2x slot.

    Will the newer cards that support agp 2x meet the voltage requirements of older motherboards?

    Firstly, welcome to Bit-tech :)

    To answer your question, I would say that newer cards will not meet the voltage requirements of older motherboards :(. From the extract of the email that Supermicro sent you, it would appear that you're motherboard supports AGP revision 1.0 (offering 1x and 2x Transfer rates), which supplied 3.3v to the video card through the AGP slot.

    Most cards these days, since the Voodoo 5 5500 use the AGP 2.0 revision (that supports 1x, 2x and later 4x transfer rates) and as such use only 1.5v, rather than the 3.3 of the older specification. Attempting to use a 1.5 card in a 3.3v slot is likely to damage the card and the motherboard :( so its no go I'm afraid, which is what I presume the Supermicro tech support meant by saying 'it might run but after a while it will stop' (as it will most likely break something).

    I know a few people who killed new video cards and/or motherboards attempting this, as they thought 'it supports 2x AGP so its AGP 2.0' which is not necessarily true....you need to find out the AGP revision apart from the supported transfer rates, which is what you've done :)

    I think the fastest card you will be able to use in a 3.3v, AGP revision 1.0 motherboard is something like a Voodoo 5 5500, which was amongst the last 3.3v cards before everything went over to 1.5v.

    Is this any help? :) Maybe not what you wanted to hear though....

    Wow! thanks for such a speedy reply!

    Well it is and isn't what I wanted to hear. I was hoping to limp through the next 6 months with the computer I have now. But it looks like I will just have to bite the bullet and build from scratch.

    I do appreciate the advice:D it saves me from a lot of wasted time and agrevation. Anyhow, it's about time I treated myself to a screamingly fast new system.

    Voltage Issue

    I read your post about AGP Voltage and, since I'm having trouble with my Asus 8460:

    The picture of Smartdoctor on Asus GF4 box shows VDDQ 3,4 and AGP Bus 3,42
    In my machine, the Smartdoctor shows only 1,58 VDDQ and I got **** on screen (starting at boot and thru WinXP) and a message says that my mobo can't suplly decent voltage or something like that.

    What motherboard are you using Martin? It might be an issue with that or also your power supply....if you're using a lower rated unit then you might struggle, as the Gf4 cards suck a lot of power that can cause your voltage rails to fall low sometimes, possibly leading to instability (or Smart Doctor yelling at you!)

    :)

    Soyo

    K7V Dragon Plus
    Tested on TUV4X e CUSL2c (both from Asus), on Shuttle (can't remember model).
    Tried many PSUs, with power from 250 to 500w and +3,3 from 24 to 30A. No luck.
    My vendor has another board with same issues (gainward 440mx)

    I had a feeling that is a mobo/PSU problem, but I RMA the board (again) to ASUS...one more moth without her....

    Why this power sucker needs 3,3v ???? Is hasn't to be 1,5 at 4x??

    Erm thats a fairly newish motherboard and video card, both AGP revision 2.0 I would imagine so it shouldn't really be a problem.....

    TBH If the system is stable I would ignore smart doctor.....

    :)
