Havent crunched for ages now and ive found as soon as i go from 3 to 4 Wu's crunching my screen will flicker and sometimes the NVidia driver crashes. Even if it doesnt it will instantly compute error all four Wu's. Any ideas on why and a possible workaround. It used to work fine before when i crunched.......... i7 920 3x2gb DDR3 2x GTX 295's ID: 15251 · Rating: 0 · rate: / Reply Quote
