ECS K7VTA3 rev. 3.1, kt333, latest bios, is definetly incompatible(!!read the edit!!). It boots up if i install my v3 first, boot up, than take the v3 out, and then put my 6k in. If i take the 6k out, put it back in it, no video. In 2d no problem, in 3d lockup in 3dmark 2001 build 330 at the second test every time i tryed. V5 6K 3700A. Gary, please add this mobo to the buggy ones.

Edit: I changed driver to SFFT and now 3dmark doesn't lock up anymore. Not to mention UT, Q3, all run fine with FSAA 8x. So excepting the fact that installation requires previous installation of another video card, the mobo works ok with the 3700A.
Best regards. Alpar
