But back to your original question, 1,4 V is generally considered the upper "safe" limit in many threads I have seen. I would not go much higher than that with a H80, maybe max 1,42 V. There was a guy that had used 1,57 V (if I recall right) by using AUTO settings for some time on air cooling and his processor's pin pads burned and later his mobo died. So be careful. Obviously the program you run doesn't tell me anything, but if it runs fine, it probably is the only thing that matters. I've used LinX to compary GFlops on SB-E overclocks since in many cases lower OC can result in higher GFlops than an unstable OC. Good luck.
I ended up backing off the OC back to 4.5 GHz. 4.8 GHz - I was about to do short runs with, but it's been having a REALLY hard time with a 30-hour run and it's been requiring quite a high voltage bump so I've decided to just back it off to 4.5 GHz and stay there while I finish the last of the 30-hour runs.

It doesn't appear to be a thermal issue that's limiting/preventing it from being stable at that OC, but I was already hitting 1.45 V (according to CPU-Z at idle) that I figured the extra 0.3 GHz wasn't worth the risk or the power. Bummer. But oh well. 30 hour it is then. It's still three TIMES faster than my old quad dual-core Opteron system (so now a 92-hour run finishes in 30-hours).
