Of course different people different definitions of "stable". For me, unless I can Fold on it 24/7 at 100% load for 4 weeks at a time without having an error or rebooting, I don't consider it to be a "stable" overclock. Others might not be so strict.
Personally, I'd rather take a couple hundred MHz hit, run cooler, have a lower voltage setting, and not have strange errors and reboots than wave my eP33n that high for more than a screen shot.
For me stable is at least 8 hours Prime @ 90% load without any errors or BSOD's. I see your point though in the extra 200MHz not being worth it.

I haven't seen any controlled studies on the issue, so pretty much everyone is just making reasonable assumptions. If your temps are in control and you are willing to risk the chip dying prematurely, then go for it - but unfortunately I don't think your going to be able to get a hard and fast answer.
Well safe being that I would be able to sustain that clock for say two years or so. However, I do understand that there is no real quick answer based on the amount of information available. Mainly, the amount of people who have had their voltages that high for prolonged periods of time. Since I cannot really find all that much information based on this scenario, I guess the best thing is reasonable assumptions.
If my temps are in low to mid 70's @ 1.52v I just am wondering if that still means I am at risk for the chip dying prematurely.

My LLC is at Level 2. Level 1 is the highest, but even at Level 1 I'm still getting a decent amount of VDROOP. So during the attempted 4.9/5.0 clocking, I was at Level 2. Do you think Level 1 LLC would help out?

The CPU had already degraded from being capable of 5Ghz barely to barely sustaining 4.9Ghz before I got into folding. I was trying to fire up a game and *poof* the machine went dead in an instant
That's what worries me the most. I don't like the idea of one day it just going dead, especially if it shows no real signs before hand of dying out.
