It's already an old article, but these days I got one FX1500m which is based en go 7900GS and one 7800, so I find out my old M70and had a try!

But unforturnly, the M70 can but start up at all, the power indicator flashed for 1 seconds, then all black

I think the Bios can not support this video card.

BTW, I would like to ask for 7800 on D810 or M70, do you need to overclock it downwardly to decrease the temperature when playing 3D games?

In mine I have to decrease the clock rate under 300 mhz (400MHz original) to keep the temperature not too high.
