Overclocking Help

[rutwik]

Okay I know it's a very old cpu but that doesn't stop me from tinkering with it  

So I have an i5 4690k with noctua NHD15 with Asus z97 sabertooth mark 2 Mobo and 24 gb's of ram ( 2x8 GB and 2x 4gb in appropriate slots ) and I have oced to 4.3 ghz with cpu core voltage at 1.190 and cpu cache ratio 40 and cache voltage at 1.190 and the DDR3 ram Freq to 1866mhz at 75-79 on load with prime 95 small ffts ( its stable ).

The thing is I tried everything from increasing the cpu core voltage to changing cache ratio but I can't get 4.4 GHz   and when I set the BCLK Freq from auto to 100.something it BSOD 

Changing ratio to 4.4 GHz BSOD 

Changing voltage to 1.24 increases the temp to 85c which I don't like at all 

Even changing the cpu core voltage to adaptive causes BSOD

Most of the time the BSOD is clock watchdog timeout error.Other errors I have seen is whea uncorrectable error ( which ithink is low voltage ) and all pc not posting when I OC my ram to higher frequencies .

BTW ambient temp would be around 30c just putting it there 

I just attached some screenshots and the last 2 are just changing fans configs on noctua NHD15 from front to near the rear case fan ( I am talking about the cpu 2nd fan ) and I got 1c change , the pc has 2 intake (120mm fans and 1 200mm side fan and 1 rear exhaust fan ) photos attached .

So please help on how to oc more and get the most out of it and how to improve cooling in general as I know noctua NHD15 is nearly equal to nzxt kraken aio . I have reapplied the noctua nh1 thermal again ( if anyone was wondering) and lossened the mounting screw a bit to see if it affects temps

 

It's my second time ocing and I hope I haven't recieved the bad batch of cpu

Your help is appreciated

Raise VCCIN (CPU input voltage). I'd run 2V from the start and see how low it can go later. No higher than 2V, that's for sure.

I tried that but as soon as i do that it crash and have to reset bios  may be some setting i can change for not tripping something that causes this crash in the bios

guess it's the high temperature then

now this hurts cooling significantly. Tighten it.

VCCIN I change and I crash into bios failure.

And I did tighten the screws  .

Adaptive voltage with 0.4 negative offset and 1.195 additional cpu turbo mode seems stable for Intel xtu for 45 mins after switched off EISI. 

Gonna just try manual voltage and try x45 

Update - clock watchdog timeout error at 45x with 1.25v on cpu core clock 7 mins into Intel XTU 

Update- clock watchdog timeout error at 45x with 1.26 v on cpu core clock 2 mins into Intel XTU

Update - changed cpu input voltage to 2.0v same clock watchdog timeout error

VCCIN is the same as cpu input voltage right ?

Yes, and it should be at least 0.5V higher than CPU core voltage.

Check the updates I am now trying 1.275 v with 45x with VCCIN at 2.0v

YEAH passed Intel XTU 5 mins 

cant upload pics some -200 error 

Load temps- 81c and idle after XTU -45-52c 

Should i try 46x or should i go for more stress tests?

Crashed with cinebench r 20

Changed cpu input voltage to 2.05 v and retrying - clock watchdog timeout error when running cinebench r20 ,

Swiched off cpu integrated fault management again crashed

Cpu core  voltage increased to 1.285 v still gets the clock watchdog timeout error
