  • G200, C300A@450,agp/pci 1/1,bh6 AGP 2X ???

    Hi!

    Anyone having c300a running at 450,
    with abit bh6 agp/pci div set to 1/1
    and gettting agp 2x with G200 ??

    if yes - how ??

    I have tried the registry hack but
    the system locks up . . .

    (or have i set the agp/pci divider
    incorrectly... ?? hope not...)

    best regards...

    you have to run the pci/agp divider at 2/3 at 1/1 you are running the agp and pci bus at 100 mhz and i don't think any card/ agp pci aor even ide device can run at that speed with out locking up or (burning up)

    i have a bh6 at agp 2x and an over clocked cpu have used both 300a at 450 and p2350 at 464 (10/103 fsb)

      hmmm...

      maybe i was i little bit
      misleading when talking about
      "agp / pci" divider . . . but i think
      we were talking about the same setting
      anyway... the "agpclk/cpuclk" divider...
      and yes . . . g200 runs very well at 1/1
      @100Mhz fsb (at least i'm doing it...)
      if i set it to 2/3 and put the fsb at 100Mhz
      the system is very unstable - messed characters at windows menus . . . if try
      to start a 3d game -> instant lockup or
      scrambled screen. Yes i know it is very
      odd behaviour , but what can you do...

      now running "happily" ...

      agp1x , agpclk/cpuclk at 1/1
      abit bh6 , FU bios, c300a@450Mhz

      so if anyone runs bh6 & g200 agp at agp2x
      i would like to know the settings...
      (and bios, driver versions...)

      (abit news group does not help much ...
      - this seems to be quite common problem...)

        I was quite able to run a G200 at AGP2X with agp divider at 2/3 and 103MHz FSB. Abit BH6 latest bios, cela300@464, G200 8MB OEMlatest bios. Same settings work fine with my G400 nowadays.

          well... maybe its the mb bios...
          looks like i have to do a bios flash

          been reading horror stories about
          failed flashes so i have been delaying
          ...

          lets see what happens...

            Hi Smo !

            As you stated you're running at 100MHz FSB using a 1/1 divider.

            With that setting you'll never get AGP2x working, because that would be an AGP clock of 200MHz where 166.6MHz is spec.

            You said you tried a 2/3 divider, but experienced graphical corruption.
            This looks like your G200 worked in AGP2x mode, but your mobo seems to be producing too much noise to get a proper output.

            There are several things you could try:

            - Update your MoBo bios.
            - If there are any, update your MoBo's AGP drivers
            - Check your MoBo bios for a Turbo-Option and disable if neccessary.
            - Update your G200 bios.
            - Use the latest G200 drivers.

            If all those option do not help to get a clean picture / stable system at 100MHz FSB, 2/3 divider and AGP2x, you should stick with AGP1x on a 1/1 divider giving you something like AGP1.5x.

              My BH6 v1.02 runs my Matrox G-200 with a AGPCLK/CPUCLK at 2/3 with AGP2x.

              It cannot run at AGPCLK/CPUCLK at 1/1 with AGP 2x, as that means the AGP slot is running at 200MHz (sort of), which is way above spec.

              It will run at AGPCLK/CPUCLK at 1/1 with AGP 1x though.

              This is with a Celeron 366MHz overclocked to 550MHz (FSB=100MHz).

              I strongly suspect that you are not running at AGPCLK/CPUCLK at 1/1 with a FSB of 100MHz, but if you are, then I don't think your Video Card is going to be sticking around for very long!

              Maggi are you sure about that 166MHz, or is it a typo?

              As I understand it, these are the following combinations on a BX Chipsetted board.

              Default AGP on a motherboard running a FSB of 100MHz for AGPCLK/CPUCLK at 2/3 is 66MHz otherwise known as AGPx1.

              On a motherboard running a FSB of 100MHz for AGPCLK/CPUCLK at 1/1 is 100MHz otherwise known as AGPx1.5

              On a motherboard running a FSB of 100MHz for AGPCLK/CPUCLK at 2/3 is 133MHz otherwise known as AGPx2

              On a motherboard running a FSB of 100MHz for AGPCLK/CPUCLK at 1/1 is 200MHz otherwise known as BSOD if you are lucky, or new video Card if you are unlucky

              Did I get it wrong, I think I am just paraphrasing something that you have said earlier, here in this forum. Maybe it was you, maybe it wasn't, I would have to check, but to the best of my memory, it was you.

                got me, Whisper ...

                2x 66.6 = 133.3, of course ...

                  HI,

                  I have:
                  CPU Celeron 400@500 MHz
                  ABIT BH6
                  MGA-G200/SDRAM/
                  83 MHz bus
                  agp/pci div set to 1/1 and 2/3

                  and I get AGP x2 both cases /pcilist/
                  How is possible?

                    Thank you for the replies.

                    I checked the divider thingie today
                    and did a "brave" 'do or die' bios
                    flash from FU to LN. (like Maggie
                    suggested..)

                    Before the flash I tried 2/3 divider
                    with agp1x 100 Mhz fsb (just wanted
                    to be sure that i had not messed up
                    earlier). It turned out that the system
                    could not handle it at all. Well I did
                    know this from my earlier experiments.

                    God Damn . . .
                    For some reason the FU bios does not like
                    2/3 divider . . . that's my conclusion.

                    Now running agp2x, 100Mhz fsb, 2/3 div.
                    c300a@450
                    Graphics bios: 2.6 -20
                    Display driver: 4.11.01.2250
                    Mini-VDD: 4.11.01.2250
                    Matrox PowerDesk: 5.25.019
                    DirectDraw/Direct3D driver: 4.11.01.2250
                    Microsoft DirectX: 4.06.03.0518

                    Lets see if this hangs after 20 minutes.
                    I happened to notice the thread about
                    abit motherboard compatibility problems
                    My two cents is that it is a bios problem
                    ...

                    Anyone with the same problems ?
                    Just get rid of the FU (or what else)
                    bios

                    thanks guys

                      I think its time you visited a resource site and read a good explanation of AGP. The 1X/2X does not refer to the AGP bus speed but rather the data transfer rate. 1X refers data xmission triggered on the leading or trailing edge of the clock pulse, 2X refers to data xfer triggered on both edges of the clock pulse. Therefore, if the AGP bus is clocked at 66MHz, you end up with either 66 or 133MHz xfer rate. This is also referred to as sideband xfer by some references. A more accurate and extensive explanation should available at many of the review sites on the net.

                        rado, it is possible but you will probably damage your card, have you tried Q2 at that setting? does it lock up?

                          Yes I know that Ron.

                          I was just trying to figure out how Maggi came up with his number of 166MHz, by illustrating how I thought the numbers did work.

                          And yes you are correct.

                            DuRaNgO, I have tried to play Quake 2 and that was succesfull.
                            My Matrox work very well too.

                            How I can overclock my Celeron 400MHz (bus 66 x6)to 600Mhz (bus 100 x6). My best try is 500 (bus 83 x6)??? I probed to increase voltage 2.00 up to 2.30, but computer halted while Windows was loading.

                              sounds like either heat:
                              A: add some case fans to exchange the air inside the case more efficiently...
                              B: get a BIGGER heatsink and fan combo on your celery (possibly a Tennmax)
                              or memory:
                              A: slow down the speed of your ram...
                              B: make sure you have PC-100 compliant sdram
