Max voltage on i7 5820k?

[smokeyvandenberg]

I was wondering what's the max (save) voltage a i7 5820k can run at? I have mine clocked on 45 multiplier and 1.3v to get a clock speed of 4.5 but I'm sure it can go higher

1.4 is pretty safe

I wouldn't go past 1,45. In fact I'd try to keep it under 1,4, but (provided the cooling is sufficient) anything up to 1,45 should be safe.

Could you explain to me how to set the voltage offset (or manual voltage) in accordance with clock speed, i have my 4690K running at 4.0Ghz 1.21V.

Well, it's a "hit or miss" to be fair, every CPU is different, every motherboard is different and one 4690K can do 4,7GHz at 1,3V and one 4690K can do 4,7GHz at 1,5V or not at all... You need to try a desired overclock accordingly to your cooler and motherboard, judging by your signature both of those are great in your case so I'd try to run 4,7GHz at 1,35V, if the PC boots without any issues I'd stresstest it and if it's stable - lower the voltage and do the same all over again. If it doesn't boot then increase the voltage until it does (provided it's below 1,45V threshold, optimally under 1,4V) If the voltage needed for 4,7GHz is too high, lower the overclock as your CPU just won't be able to do 4,7 and repeat those steps.

 

Remember to monitor your temperatures and don't let them exceed 85 degrees if you want a 24/7 OC, it shouldn't exceed that temperature.

 

Hope this explained it more or less.

Good luck overclocking Feel free to PM me if you've got any issues.

Top fella.

A lot depends on your cooling solution too.

My 5930K (cooled by a Dark Rock Pro 3) is hitting 95°C at 1.35V, which is 10°C higher than recommended for the X99 socket. 

Given the similarities between the 5820K and the 5930K, I'd start with 1.25V and see how far that allows you to go.  When the system becomes unstable, see how far you can up the voltage while staying below 85°C.

 

FYI I'm now at 4.5GHz on 1.24V and hitting low 70s.  I can do 4.6 at 1.35V, but then I'd need to switch to a custom loop.
