Hello all. I've been using Prime94 blend test but always have a core failure 3-4 hours in. I want to tell myself my overclock is stable but can't get to the eight hour mark without one core failing. I've read that prime95 isn't the best for fx prossesors. I'm overclocking with a 20.5 multi and 221 fsb to get a little over 4.5ghz temp are 56 at the socket stressing with a max of 61. Could it the spike of 61 2 hours in making the core fail. I've pushed my vaults to 1.43 and nb core to 1.25 on my last test and still can't get past 4 hours. Ram it set at profile settings. Any other suggestions for other programs.
