View Full Version : G400 MAX overclocked

11th September 1999, 13:59

here're my parameters using mgatweak
fo=405.00 mhz
gclk=fo/2.5 = 162.00 mhz
mclk=fo/2.0 = 202.50 mhz
wclk=fo/2.5 = 162.00 mhz

it's working fine...

Note: if you overclock the memory more than the default 201 mhz several small white pixels will be display during a direct3d animation... so avoid to overclock the memory just overclock the graphic clock.

Using your settings for
I am able to clock my MAX to 425.25 or
170 Core 212 mem. Not seeing much of a difference in 3DMark, but other games sure do enjoy the speed increase, especially in higher res.

Thanks for the tip on changing the dividers!

Set record 3D Mark of 5602 at 1024/768/16.

The 3D mark scores do change but you need to run at a resolution higher than 800x600.

P3-450@580 G400Max@166/207 AGP1x 256MB@129 Abit Bx6r2
