i7-5820k voltage

[suchamoneypit]

Quick question I couldn't really find anywhere. What would be the max safe voltage on a i7-5820k? On Linus's guide, he said 1.4 volts, and he was getting around 80C If i recall correctly. Im trying to get a stable 4.7 ghz, 4.6ghz is already stable. I've managed to put the voltage slowly to 1.45 its only running at 61-62 C on 4 of my cores, and 67-68C on 2 others cores ( cores 5 and 6). Am I safe to up the voltage as long as the temps stay good? or can I damage my CPU even if temps remain at a safe area?

 

Also as a note, at 1.45 volts I got 4.7ghz to run with flat lines for temps for over 2 hours running the AIDA stress test on my CPU, but I get freezes about halfway through cinebench (just cinebench) and then a system restart, no such errors at 4.6ghz 1.4 volts,

 

Also, If i cant get to 4.7, on the X99-UD4, is there somewhere I can change the clock more finely? such as 4.65? I cant seem to find anywhere where I have more fine control over the clock.

If you're getting freezes and restarts at 4.7 then it's not stable.

Just try to find the lowest possible voltage for your clock. The ratio is the best way to fine tune the clock but don't mess with that unless you need to.

You can fine tune using the CPU multiplier.

Can fine-tune the processor's frequency.

What cooler do you have? 1.4v sounds a bit much. If you're getting safe temps, it shouldn't be a problem tho.

You can try upping the base clock a bit. To like 101. That'll give you 46MHz over the 46 multiplier.

More volts = lower lifespan, you can damage a chip even with great temps if you feed it too much power. I would exercise caution and not get greedy when overclocking. Can you notice the difference between 4.6Ghz and 4.7Ghz? Do you even need 4.6Ghz? I would get what you need out of it and leave what you don't need for later. Better to have a 4.6Ghz 5820k then no 5820k. You can always use 4.4Ghz or whatever and keep your chip safe for when you need that speed later rather then burning the horse up before the race. If you really need the speed I've not seen many go past 1.45v. Max safe voltage is usually said to be 1.4v I don't know what it actually is per Intel spec.

Im running a Corsair H100i 240mm AIO liquid cooler just so you know.

thanks. Pretty much what I was looking for. Im going to take your advice and step the voltage down to 1.4v max. at 1.45 I was already uncomfortable with the zig zag temperture lines in MSI afterburner running at idle so I immedietly turned it down.
