Well, this is where I get shafted pretty much every time in life. My luck is absolutely horrendous about 98% of the time unfortunately.
Good news is though I managed to get my 4.8GHz OC to a flat 1.4v. Is it safe to run this 24/7 or should I shake a stick at the Offset mode?

It's not like 4.8 GHz at 1.4V is bad, your chip is average. The people who get there at 1.35V just got really good ones.

Yeah, i'm happy where my chip is currently, maybe I can snag a 4.9ghz at like 1.42 or something. What voltage would be the absolute max to run 24/7 without serious degrading after a few years of use? Around 1.45? I know it's different for each one, but just an estimate would be appreciated if anyone can ballpark it for me.

Im pretty sure 1.48 is not safe for 24|7 usage on SB
So many times ppl post saying the max vcore for an i7 2600k should be some such number (usually somewhere between 1.35 and 1.45), so I don't blame you for misleading - you most likely heard someone else you thought was a reliable source on OCN or another forum say "Intel suggests..." and just took their word for it wink.gif

But if you check the specs of the CPU in Intel's own datasheets, you'll find their real suggested max is much higher.

Here are the specifications for you (excuse the formatting) - as you can see, the max is clearly not 1.38-1.4:

Specs say max is 1.52v. If you don't believe this, go to intel's website and check the datasheets - table 7-4.

The question is, would that be safe to run for 2-3 years 24/7 (around the 1.48v i'd need for 5ghz? Possibly more I still don't exactly know.) I might set the vcore to auto and see what it puts me at when i'm sitting on x50 multi. I'll probably upgrade around the 3 year mark, maybe skip the newly released intel chips and go for the next batch. Definitely keeping my 2600K for quite some time though, literally put my pc together like 2.5 weeks ago.

IDK what spec sheet some of these guys are reading..but the one I read said 1.52v max vcore
and 72.6 Tcase max

Okay this is going to probably be an idiotic question to you guys, but go easy on me i'm just making sure this is 100% okay. Say I found my stability was perfect at my 4.8ghz 1.4v 1.6875 PLL and 1.2v VCCIO, and I go and change the settings to seek a higher overclock and I find that it just isn't working out. Would I be able to just come back down to that stable 4.8ghz without having to run it in prime to make sure it's stable again?

I ask because I was thinking of just setting the vcore to auto and seeing where it would put me at 5ghz. I've aleady ran the stress test on the 4.8 beautifully, but i'm curious as to what exactly my chip needs for 5. I know it'll overshoot when I set it to auto but if it's reasonable maybe i'll actually try and manually go for it again.

Someone, please? I would really like to know if I have to keep stress testing to see if it's still stable.

Yeah it should work.
