I have a classic Athlon 600 and Fic Sd11 motherboard. I installed the GDF. I get a black screen. I then have to kill the power and reboot into safemode to get it up and running again. I have tried reseating it several times and even tried running it at 600 with the same results. Anyone have any ideas. I have e-mailed Northwind support but they have not responded so far. Thanks!
