i7-6400T OC Issue

[cloud1250000]

Hi!

 

I'm trying to overclock my cpu but I can't go over 3.0ghz... It's stock speed is 1.6 ghz turbo at 2.2ghz.

 

Sadly, my max multiplier is 20 so I need to rise the bclk to get a suitable overclock.

 

My motherboard is an Asus z170i pro gaming and I easily reach 3.0ghz with 150x20 @ 0.95V. (stable)

 

The problem is when I go over 150, it doesn't post anymore and I have no insight on what I should do to make it work..

 

I need help lol

 

Thanks!

You need more volts than 0,95V and some other voltages like dmi, cpu standby and so on might need raise as well. 150 is also 50% oc, I think you will have to fight hard to get a lot higher stable.

I tried setting the bclk to 155 and raised the voltage up to 1.15 and, no chance, still booting to black screen.

 

I'm not looking for something too high since I only have a noctua nh l9i for cooling right now (i'm pretty limited in space)

 

150 bclk with everything enabled. C-State, SpeedStep...

 

I can push it a bit further by setting my multiplier to 21 and it seems to be stable too (somehow)

 

Currently, I'm using the igpu, maybe I need a dedicated gpu to get higher right?

Oh well,

 

Here we go, I got 3.4ghz with a bclk of 170 and a multiplier of 20

 

 

I raised the voltage to 1.1

Why are you running such low voltage? Up it to 1.35 and have at it.

Why are you running such low voltage? Up it to 1.35 and have at it.

 

because it's a really small computer.

 

 

and I'm currently running at 3.7ghz with 1.15 vcore

Delidded?

Also you need more voltage than normal since CPU freq is linked to cache freq (both are the same).

If you delid CPU and put liquid metal as interface between IHS and DIE temps will be OK even with than cooler.
