I'm currently trying for P95 Blend stable. I'm on BIOS F4 with a 1.0 revision board. I can get it stable for about 50 mins before 1 core will fail in the large FTT test. I can pass Small FTT though I'm pretty sure I just need to tweak the NB somehow. Here are my current settings, any idea on what I need to tweak? I can run 4GHz totally stable with 1.2500v vcore set in the BIOS (CPU-Z 1.248v under load).

4.1GHz stable
