Help Overclocking i5 6600k

Hello guys,

I'm new on this forum and new to overclocking. Recently I bought an i5 6600k and I want to overclock it. I have no experience in overclocking a CPU so i need your help.
I tried to overclock the CPU by modifying the multiplier (the voltages were on auto) and I managed to get 4.5GHz but voltages went to 1.35 so I stopped (The temps in AIDA64 Stress test were below 60 *C). I'm afraid that i would do something bad so I want your advice.

Then I tried to modify the BCLK as mentioned in this review but my PC keept restarting and i had to clear CMOS. So I lowered the BCLK and multiplier but the same thing happened.

I want your advice, what should I do? and what i did wrong?

This is my PC:

CPU: Intel Core i5 6600K
CPU COOLER: Phanteks PH-TC14PE
MOBO: GIGABYTE GA-Z170X-Gaming 7
RAM: HyperX Fury Black 8GB DDR4 2133MHz CL14
PSU: Seasonic M12II-850 EVO Edition Bronze 850W


And here are some screenshots of default setting in Bios:

First, I'd manually set the voltage to about 1.3 V, if you go higher with your overclocks maybe to 1.35 but I really wouldn't go higher that that, obviously you need to keep an eye on the temps too. Then I suggest you first only overclock using the multiplier, and see how far you can go, this is really easy and should give you some nice results. Just make sure you slowly work your way up and always test if the current OC is stable before you increase it.
If you then feel comfortable you can start playing with the baseclock, there are many forum member that know a lot more about that than I do, so I'm sure someone will help you there.
 
Thank you for replying!

I'll watch that video tonight, I can't at the moment because it's quite long.

Ok so let's say I set the voltages to 1.3, do I need to disable TurboBoost when I play with the multiplier? Shall I change other settings?

I don't think you need to disable TurboBoost, I never did when I had my 2500k overclocked. Just enable your ram's XMP profile, or set the values manually if you want. Other than that you don't need to change any setting for now.
If you found an overclock you're happy with, you can try to find the lowest stable voltage.

Ok, thanks!
I will try to see the limit on 1.3v.

If someone has some advice about BCLK overclocking please share it. I want to learn from you :).
 
Hello guys,

I managed to get 4.5 GHz at 1.32v. I tried to go higher but I get blue screen. temperatures are 51 *C and below (at a room temperature of 28.5 - 30 *C) on AIDA64 Stress Test and OCCT.
I went to 4.6 with 1.35 and everything was fine. Tried 4.7 at 1.375 but I get BSOD.
I will wait for a new BIOS and try again see what happens. Maybe it will work.

Do you have any suggestions? Should I try something else?

@Cru
I watched that video, it was very helpful.
 
You are getting pretty high in volts. I wouldn't go any further to be honest. 4.7ghz is pretty respectable and what reviewers have seen as well. To get those down you would need to do some BLCK work. Skylake seems to really like it.
 
With my 6700K I have achieved 4.6GHz at 1.32v and 4.8GHz at 1.375.

I have had a good time overclocking with a base clock of 200MHz, as getting 4.6 required more volts for me than using a 100MHz base clock.

This is something that you will need to try for yourself, as I have only tested one chip.

I want to try BCLK overclocking but I have to do more research.

@WYP
How are you setting the memory when you increase the base clock?
Mine is 2133 and if I play with BCLK I can't get that value.

I tried yesterday to go 120 x 35 at 1.35v but it won't boot. I think it might be because of the memory, but I'm not sure.

Shall I increase BCLK more and reduce the multiplier?
