Hit a wall at 3.4 gig 3350 was fine at stock volts.......been doing 50mhz increments prime for over an hour then up more..........when i say wall i mean that minor voltage ( 1.230-1.240 ) isn't going to cut it nor is the stock heatsink with anymore volts..........., its late i backed it down to 3150 and am gonna burn it in overnight.
