  • overclocking

    hey all,
    i have a G400 dual head and downloaded the matrox overclocking/tweak utility. any ideas on what speed is safe to overclock to? (i.e. percentagewise, like 120% etc). I am going to buy a fan for the card anyway but don't want to fry it. thanks for the info.

    my system:
    Dual celeron 525 w 128 megs ram
    Quantum fireball hard drive
    DaKine

    I wouldn't go over 115% as G400s are already pretty optimised.

    there would probably be no benefit at all to trying to overclock a MAX
    If you can understand my post, then you are missing the point entirely.

      why are people using the matrox overclock? MGA Tweak is way better.

      My G400 32mb dh scores 34% better in quake2 at 160/200 over the default 126/168

        Chaos....

        I'm not sure I understand you statement there would probably be no benefit at all to trying to overclock a MAX. I'm overclocking mine at 110% with not a single problem and measureable increase in performance.

          Just got my G400 dh today and the card cooler.

          I have my card overclocked at 125% using the matrox utility or a 157/210 reading on the tweak.

          works great and what great visual quality

            I added a fan on top of the heatsink and my Vanilla runs at 125% without any probs ...

            Needless to say that the gain is not only measureable, but also subjectively noticeable.

              What is the maximum SAFE OC you can you can do to a G400 32Dh without a fan
              Where can you download the MGA tweak utility is why is it better than the matrox util ?

                MGA Tweak is more for the avid tweaker. It allows you to play with the dividers and memory settings. I love it

                  I've got my non max 32mb card set to 120% with non problems. Added a fan to see if it'll go higher but no go... It must be the memory chips that are hot with no cooling....

                    Greebe-

                    I'm using a PIII 450 overclocked to 504 MHz (4.5 X 112 FSB) on my faithful (and old!) Asus P2B motherboard. What's funny is that the memory I'm using to acheive this is PC-66. Rock stable.
