    err..Rickn, are you sure about those numbers. Seems to me that a G400 at 160Mhz core is like 128% overclocked. And since the Max is set to 150Mhz core 200Mhz memory, wouldn't your memory be somewhere around 213Mhz?

      I dont use the crummy matrox overclock, I use MGA Tweak. 401 system PLL, 2.5 gclk and wclk, 2.0 mclk. With the Matrox overclock I did 120% just fine. I prefer MGA Tweak

            Used Matroxes util and 120% worked fine. Have large fan blowin at heatsink, so its extremely cool. I took it to 130%, and still cool, games seem ok half the time, occasional funky colors. Not all the time. Could I keep pushing it? Heatsink cool, the large fan seems to be doing the job. Got the fan from some old AT comp that had a fan that plugged into its own outlet.

              How many have the 5ns memory chips on their G400 (non MAX)?

                Is there an easy way to check the speed of our G400's ram (5 or 6 in the serial # of chips or something)?

                  Well, yeah. Thats where it says -6 for 6ns ram (166.66Mhz sreed ram for the G400) and -5 for the 5ns ram (200Mhz speed ram for the Max).
                  This is indicated on your memory chips on the g400.
                  I am just wondering those than can overclock their G400 like crazy ( >120% ) actually have the faster ram. Cos we all know these are gems G400Max's that never made it as a Max and were sold as a regular G400 with regular G400 price.
