I wouldn't say 1,5V VTT 24/7 is safe. More like 1,45 absolute max, if you can keep it at or below 1,4V.
Well, I do not really agree, but that's my opinion. I like to run really high Uncore (don't ask why, it's more for s and giggles, not any particular reason) and I ran my VTT ~1.5V for a very, very long time on several chips. I did not have any problems. I think that it is a toss up and it will vary chip to chip, hence why I said YMMV. My opinion does not change though...from my experience high VTT is okay.
