So, a few months ago I upgraded from my chisel and slate FX6300 to an i5 6600k. Obviously you're expected to overclock this cpu and I have to the tune of 4.8ghz. But, this requires the voltage to be set to 1.43 in the bios (1.39v under load). This doesn't worry me that much since I plan on upgrading in 2-3 years time, but I still need the cpu to last those few years.
I'm not sure if we've officially agreed on a safe voltage for Skylake. I've seen 1.52 as the max and I've seen people say that 1.35 should only be used to power the sun. I also think most of these definitions of "safe" are used for chips that are going to see 10 years of usage. So, I have no clue.
Whats your guys opinion? I don't really use my pc a lot though. Maybe a few hours and then I always turn it off. So, I'm wondering if keeping the 4.8ghz overclock is worth it with this voltage.
I should also mention that temps never exceed 64c during x264 stress testing and 77c during Intel Burn Test.
If anyone has a suggestion as to what I should set the voltage to for CPU SA, CPU IO, CPU PLL OC, CPU PLL SFR and CPU ST PLL, I would greatly appreciate it.
I think for high end gaming it can be worth it. Otherwise no
There are other workloads where higher clock speeds can be beneficial other than gaming...
I do a little bit of everything. Gaming comprises about 15 hours of my pcs up time a week. Really wish I had something other than a 970 to take advantage of the overclock.
not soon enough. 1.4v in a 14nm chip... it's gonna last a year before it basically can't OC anymore.
Are we sure that happens to these chips yet?
i've degraded an OC on a 4790k (22nm) in 6 months so... yeah. I don't even have the slightest doubt.
Degradation is sort of weird in my experience with my 4790k. Mine used to run stable at the stock turbo of 4.4ghz @ 1.088v. That lasted nearly a year. Then I had to bump it up to 1.104v, then half a year later up to 1.126v. Now, 2 years later, it needs 1.136v for the stock turbo frequency.
Here's the thing, though. When I'm overclocked to 4.8ghz, it'll still run stable with the same vcore that I used 2 years ago, which is 1.29v.
(Edit) I guess you can say that 1.29v was too much for 4.8ghz 2 years ago, but is appropriate now. Never actually tested it... So who knows...
Your CPU won't be unusable if you degrade it a bit. Just put it back to stock or lower the overclock.
I realize that. I'm just talking about my own experiences
I've OC'd a 4690k to 4.5 for over 2 years now...

The discussion is about whether the affects of the high voltage required for his overclock are worth the trade off. If you mentioned the voltage that you're using on your 4690k, and if it's quite high, then your post may be relevant to this topic.
As for your experience with your 4690k. 4.5GHz is pretty modest. I'd be surprised if that caused any noticeable harm at all. That's if your voltage is where I'm guessing it would be.
I'm selling a few 6600k's if anyone is interested.
Just dial it down to 4.5 and turn the voltage down. I doubt you'll notice a fps difference if you're not just watching the counter.
4.5 is still huge
