When it is running in that mode, the picture has lines of randomly blinking pixels (sort of looks like a TV with a bad reception). -The board works fine all the way up to 1024x768, 16colors. -The severity of the problem varies w/temperature of the RAM. -The board uses the Ahead V5000 chipset. - 256Kx4 80ns memory chips What could be the problem? Video RAM not fast enough? (I ruled out a flaky RAM since this is the second board sent to me with the same problem) -Doug apollo@raven.bu.edu
