    ramdac overclock via pins!!!

    it's possible by reprogramming bios pins!!!!!
    my default value is:
    8 bit 250mhz at 270
    16bit 250mhz at 270
    24bit 250mhz at 260
    32bit 214mhz at 230

    WHY would you want to overclock the RAMDAC?!
    All you are doing is overheating it and burning it out sooner. This provides absolutely ZERO performance increase.

    All it does is let you high resolutions at higher refresh rates. So instead of 1600x1200 at 75Hz, you can get 85Hz and burn out the RAMDAC. Also, I don't know how many people actualyl have a big enough monitor (21") to have it be useful to run at that high a resolution.

      rylan why you are juging him.

      Maybe his goal is to burn the RAMDAC.

      or he have a big 21 inch monitor.
      My concern is with growth. You must grow to become one, to become whole, to become sane. I am not going to force sanity upon you. Rather, I am going to bring out your insanity. When it is pulled out completely, throw into the wind, sanity will happen to you, you will grow. You will be transformated. That is the meaning of meditation

        So many of us overclock to max settings then why not go the whole hog with the ramdac?

        As with most things they're probably capable of more than specs.

              Won't overclocking the RAMDAC slow access to the video memory?

                Dear RAMDAC overclockers,
                Below is a copy of my post to another thread. Enjoy.

                He he he!!!
                Strange, most of you guys completely misunderstand the RAMDAC clocking. The RAMDAC
                frequency depends on the current video mode (screen resolution and refresh rate. I tried to explain it many, many times on the forum. Some information on these topics is also on my website. The "RAMDAC speed" you are talking about is not the actual speed, it's the speed limit established by Matrox. At 85 Hz vertical refresh, the RAMDAC is clocked at about 90 MHz in 1024x768, 157 MHz in 1280x1024, 230 MHz in 1600x1200 and 360 MHz at 2048x1536. "Overclocking the RAMDAC" means changing its speed limit. The 300 MHz limit prohibits 2048x1536 at 85 Hz, otherwise is more than excellent. You do not "overclock" by just changing the limit - the RAMDAC will still run at the same speed in most of resolutions. This way you only allow it to be overclocked in the highest resolutions, provided that your monitor will handle it.

                So there is no danger in changing the speed limit from 300 MHz to 360 MHz - it doesn't really change anything as long as you stay at 1800x1440 or below. It only allows to reach
                2048x1536 at 85 Hz in which case tha RAMDAC will actually be clocked beyond the originally specified speed.

                The main effect of changing the RAMDAC speed limit in PInS is voiding your warranty...

                  rylan. I was in a existential questionnement.
