Again, this seems very strange to me because I haven't seen anyone else have this experience. Are you absolutely certain that for your setup, x264 v2 requires more Vcore than prime95 27.9/28.5 with FMA3 disabled? Prime runs hotter, draws more power and has always been excellent at detecting errors. It should need more Vcore than x264 v2.
4.4GHz @ 1.125 VID passes 100 loops of x264 V2 but fails prime95 28.5 blend with FMA3 disabled after anywhere from 30 minutes to 2.5 hours. Bumping Vcore up to 1.135 VID allowed prime95 28.5 with fma3 disabled to stress longer but still crashed at the 20 hour mark.
