"Overclocking failed!" I didn't OC anything tho

[Mefu720]

Hi. I'm dealing with this problem since July 2016, but I guess I'll finally bother and try to fix this already.

Current specs:

OS: Windows 10 Home 64bit
MOBO: Asus Z170 PRO GAMING
CPU: Intel Core i5-6600K
GPU: Asus GeForce GTX 1070 ROG Strix
RAM: Corsair Vengeance LPX (2x8GB, 3000MHz, CL15)
PSU: Corsair RM650X (650W, Modular, 80+ Gold)
+ SSD and 2 HDDs

As of right now whenever I try to boot up my PC for the first time that day nothing happens (fans are working and the lights light up inside, but nothing shows up on screen and the lights in for example mice don't light up). Then after rebooting this shows up:

So I enter the BIOS, click the Advanced Mode, and let these things load:

(If I don't do that, and instead just exit BIOS and boot up the system, then Windows thinks something aint right and tries to repair itself)

Well, it wasn't always like this. When I first have build my PC, the system was booting up just fine the first time, BUT it would always get a bluescreen after like 10-30 mins with those error codes:

IRQL_NOT_LESS_OR_EQUAL
SYSTEM_SERVICE_EXCEPTION
SYSTEM_SERVICE_EXCEPTION win32k.sys
INTERRUPT_EXCEPTION_NOT_HANDLED
KERNEL_MODE_EXCEPTION_NOT_HANDLED ndis.sys
KERNEL_MODE_EXCEPTION_NOT_HANDLED ntfs.sys

(After restarting everything was working just fine once again, no more BS and random crashes on games and programs like Chrome)

This (the boot up on the first try, and bluescreens afterwards) stopped once I have upgraded to my current build, before the upgrade the specs were:

OS: Windows 10 Home 64-bit
MOBO: Asus Z170 PRO GAMING
CPU: Intel Core i5-6600K
GPU: Gigabyte GeForce GTX 660
RAM: Corsair Vengeance LPX (2x4GB, 3000MHz, CL15)
PSU: Cooler Master G550M (550W, Modular, 80+ Bronze)
+ SSD and 1 HDD

So, I have changd my PSU, GPU, one extra HDD and 8 more gigs of RAM.

I would also like to note:
1. Extremely rare, but my BIOS froze a few times after entering it. That didn't happen in like a year now though.
2. My MOBO was damaged at the beginning, and just didn't work for some reason. I got it back repaired (not replaced) thanks to RMA.
3. I didn't touch anything in BIOS expect the boot order, so no overclocking done by me.

I've done some research, and from what I have read the most likely cause of this problem is RAM. [Here are my BIOS settings along with CPU-Z screens]

As I have said, before changing the sticks from 2x4GB to 2x8GB (CMK8GX4M2B3000C15 to CMK16GX4M2B3000C15) my PC would boot up to Windows on the first try, but end up with a bluescreen not so long after. Then after upgrading I'm stuck with what I have described at the beginning of this post. Before the upgrade and after it my RAM speeds are always 2133MHz instead of 3000MHz, and my CPU seems to be somewhat overclocked a little anyway (based on the clock speeds showing up in Windows).

Sooo, how can I deal with this? Along with fixing this I would also like to finally (and hopefully) overclock my CPU to 4,5GHz and fix the RAM to run on 3000MHz instead of 2133MHz. Hope you guys can help, cheers

OK..glad that sorted it

The OC...yeah, should be that simple...just check voltage and temps...maybe go up in steps

[Mefu720]

Might do it later today then. What program would you recommend to test the system stability overnight? And about voltages, will 1.3 be enough?

[Arne_Saknussemm]

No idea on volts...each chip is it's own world...you'll just have to experiment...see what auto sets and try and reduce it.

Personally I'd use RealBench for an hour and call it a day...test with my daily use

I recently got back into, or should say trying to get back into gaming. I am just taking a break here, being retired and all, I tend to overwork myself.
Actually taking a break from my self induced insanity of trying to get my game to load and play for more than 5 mins.

But I am posting this just to say I am grateful for all the wisdom and support that can be found in these forums. I am learning much just from reading about other folks issues and mistakes. I know when I get grinding away on my PC trying to fix stuff, I often overlook the sometimes most simplest or basic things. For me, calming down and reading other related stuff often clears my head and allows me to see through all the fog I created in my own head.

Thank you all for being here to share you experiences, wisdom and suggestions to us who have yet to overcome such challenges before us.


Looking forward to conversing with some of ya'll in the future. In the mean time, I will try to not screw my stuff up, much.

I've overclocked it to 4.5GHz, and so far it seems like it's all good.

I've also noticed that my CPU has kinda lower voltage needs than the majority of other i5-6600k(s)? At 3.9GHz it needed only 1.120V. Rn that 4.5GHz is running at 1.300V (with 1.35V recommended).

Dunno what that means, but maybe I can squeeze 0.2 more GHz out of this chip without crossing the 1.4V line

Might mean you have a goods chip...silicon lottery winner...just keep an eye on load temps and have a play about...that's what it's all about...testing...try 4.6 at 1.3...etc.
