Max safe voltage for my i5-6600K

[Dunkan77]

Hello guys,

I was wondering what may be the max volateg for everyday use would be. I am currently running reported 1.36V on Vcore (Hw Monitor) and 4.7 GHz on a Corsair H100i V2 CLC.

Is that safe? and Should I add like 20mV to try and hit 4.8 or is it getting a bit high?

1.4v is considered the max safe voltage for the average user on Skylake. I personally think your 1.36v is a good place to stay.

Unless you have to add a ton of voltage for it to be stable, it's fine. So keep going until you feel like you have to add too much.

1.4v is considered the max safe voltage for the average user on Skylake. I personally think your 1.36v is a good place to stay.

So you're saying I realistically have 40mV of headroom? What about the chip's longevity? I plan to keep it for at least 2-3 years so will that change your recommendations for me?

It depends on your willingness to accept risk. It is still considered safe, but it is the maximum of safe. I think if 3 years is your target lifespan then 1.4v is probably fine.

Okay so I will try to not go over 1.37 to 1.38 then. Is this enough below max safe to be safe again? (If that makes sense xD)

It's probably fine. There's people out there running these chips at 1.45v. But that's not recommended for the average user (hence my wording in the original post.) There's really no way to know exactly how long the average Skylake chip will last at 1.45v, 1.4v, or 1.35v. It just comes down to how willing you are to accept risk.

The average OC'er on a 6600k is running 1.38v according to one collection of user data online. Also, the top 22% can hit 4.8Ghz at or below 1.4v and the top 4% can achieve 4.9Ghz. I would probably want to see how high of a stable OC you can get at 1.4v to determine how good your chip really is and see what temps you get. And then you can decide how much value there is in backing off a little. For example, if you can hit 4.7Ghz right now at 1.36v and 4.8Ghz at 1.4v but with a 10c difference. I'd probably just back it down to the 4.7Ghz as the additional 2% in clockspeed isn't worth the 10c.

Thanks for the wise words my friend, I will update this post or create another one about my OC results on my chip, determine its max clock at 1.4V just for testing's sake. Also, should I look at reported BIOS target Vcore or the one HW monitor shows? Because in HWM the voltage is 1.360 V but I set it to 1.315V in bios...

 

[timeconsumer]

Is the 1.360v in HWMonitor the VID or the Vcore?

have you read this: http://www.overclock.net/t/1570313/skylake-overclocking-guide-with-statistics ?

Yeah I saw the thread and no it is the Vcore in HWM. Does the BIOS report VID?

 

[timeconsumer]

That's really odd for your HWM Vcore to be higher than your BIOS Vcore. Usually it's the other way around from Vdrop. How are you setting up your LLC, adapative, and/or offset voltages? What motherboard are you using? A lot of them do a lot of automatic adjustments if you don't have everything set manually.

Yeah but it doesnt matter it seems like my chip hits the wall at 4.7 because 4.8 doesnt work even with 1.4V so I will back down to 4.6 at 1.34V. Thanks for all the help nonetheless. I am changing PSU soon so maybe I will give this another shot to try and hit 4.8 again.

 

[timeconsumer]

That's pretty typical, you have pretty much a 50 percentile chip with 4.7Ghz. 4.8 is only 2% faster so I wouldn't worry about it that much. What are you changing your PSU from/to?

I have some faults with my current RM650 and I'm getting its newer version the RM650x since I don't need much more power and my experience with this psu is great. The issue was caused by another faulty component that now isn't in the system anymore

 

[timeconsumer]

The new RM650x is very nice. You'll be happy with it.

hate to revive an old thread, but at like 1.41 or 1.42 something I'm able to keep a 5.0ghz oc with a corsair h100i v2 with corsair ml 120s
