So we can overclock the non-K Skylakes now. Surely makes the whole range more interesting.

I am very new to this and I only managed to get it up to 3840MHz by increasing BCLK to 120MHz with my Corsair Vengence LPX DDR4 3000 running at 2880 14-16-16-36.

I would like to get the CPU to above 4GHz but it wont boot on BCLK 125MHz.
Do I need to change voltage or something else?

It is running really well on Noctua cooler maxing at 65C in gaming and idling at just above 30C.

The motherboard is Asrock Z170M Pro4s with BIOS 2.23

Many thanks for your time

not sure mate but locked multi normally just means its at its locked maximum. sometimes theres an option to lower it. i guess it will depend on your bios support.

dont forget about uncore.. the cpu's mmu ram cache.
the uncore is also tied to the base clock so try adjusting its multi if your having to drop your ram multi a lot.
also make sure your ram isnt set higher than your uncore frequency or the pc wont boot.

on my old i7 the uncore is x2 the ram frequency minimum. i would add +2 to the uncore if i was oc-in'g the ram directly or pushing the ram past spec with the cpu oc.
also had to add .020v to the uncore voltage.

on yours as its newer hardware the voltages might be different but the method seems to be the same.





Hey there. Yes it is possible:) a Z170 motherboard is required... I have a Gigabyte Z170-HD3 and it's been perfect... You have to have a Z170 chipet to overclock. Also if you want to SLI make sure you get a board that suppors it. In terms of BIOS, they are downloaded from overclocking.guide. Easy peasy to flash. There is a video on that site to show you what to do :)
 


I've just been using HWiNFO and reading the package temp. Like to keep it under 60...
 


Thats what i use but when you overclock a non k processor it doesn't read temps
 


It reads package temps, but not core temps
 


Using the same MOBO w/ Skylake i5 6500. Currently OC @ 4.3GHz. Set my voltage to "fixed" @ 1.395, BCLK is 135, RAM is set to 2160. OC'ed to 4.9GHz once, but it wasn't stable; kept BSOD'ing me. I am using a rather cheap RAM....(G Skill DDR4-2400 15-15-15-35 1.2v) Try those settings and let me know if how it goes for you.
 


Well I'm stable at 4.3 Ghz on 1.32V
 


I have mine @ 4.3GHz with Package Temps never above 60 under stress. Whilst it isn't OCed core temps are higher than package temp (HWInfo, I think)... Even if core is a bit warmer, I am comfortable at that... sits around 30-40c. Cinebench scores are 710.
 


Do yo have a Asrock z170 pro4s or another mothearboard?
 


Gigabyte Z170 HD3

 


What voltage are you at?
 


I am looking for a Z170 mobo, ive seen that z170m pro4 is the cheapest one, so i wanted to know to overclock a i5 6500 to 4.3 ghz
 


Buy a board. Flash a BIOS. Set your BCLK. Reduce RAM multiplier. Set Voltage. Done.

There are online tutorials.
 


I think you mean 1.32? But that's good. I'm 4.35ish on 1.3...
 


Ya i use the asrock z170a x1 which is very similar
 


It is actually really simple.
 


Somebody has tried asrock z170m pro4/pro4s?
 


your MB fried? what mb did u have, and what was your voltage at ? and did u have a aftermarket cooler ?
 



dude how did you overclock? my BCLK won't change no matter what...

i have z170a gaming 3 msi and i5 6500 1x8 ddr4 lpx 2666mhz
 
Fatal1ty E3V5 Performance Gaming/OC
so this mobo can BCLK overclock too ? in the homepage bios list i was seen "Remove Sky OC function" but asrock said:
- Supports ASRock BCLK Full-range Overclocking
- Supports ASRock Hyper BCLK Engine
what's it mean >?
i am planning buy this with xeon e3 1230v5
