What voltage would y'all recommend for the CPU FSBwith a E8400 on 790i at 3.6 (1600 linked/synced)? The CPU Core is on Auto (1.32v in CPUID).

I had all voltages (except RAM) set to Auto, but was experiencing lagging and freezing in Crysis. I manually increased the CPU FSB to 1.35v from Auto-1.30v and increased the SPP to 1.40v from Auto-1.30v, and it lags less, but was wondering if I should increase the FSB to 1.4v instead of 1.35. The only problem is that it is in red instead of green. Before I put the E8400 in I had a E6750 and it automatically set the CPU Core and the CPU FSB to 1.4 (green).
