If You have any suggestions about OC (different options or something) please respond :)

Thank You :)

Hello all,

Thank You for all your posts. That was very fast and precise help.

I clear CMOS + reconnect all cables and now everything works flawless : )

About OC - currently im on Offset + 85mV with 4,3 GHz LLC level 1 and cache ratio 39.

I tried some of 4,5 GHz with 1,39 V ~ 1,408 V but it crashed after 5-10 minutes (1 core).

I think I just lost silicone lottery :)

But... about PSU topic - everything works and im really grateful :)

This issue reminds me of the Wake On LAN situation, when power to the PSU is removed, and then restored. When Wake On LAN is enabled in the UEFI/BIOS, the board will start for a short time to initialize the networking chip, and then shut off, when power is restored to the board. BUT that does not seem to be what is happening to Ky0sHIR0. You could try setting Wake On LAN to Disabled in the UEFI/BIOS, if you have that option and it is Enabled.

Personally, I have never had any of my ASRock boards start for a few seconds, and then stop, when AC power is applied to the PSU, such as after working on the PC. I have all Seasonic Gold and one Platinum PSUs, and one EVGA G2 PSU, which is made by Seasonic. Honestly, I have never had a PSU that would start for a few seconds when AC power is first applied.

Ky0sHIR0 do you use the power switch on the PSU, or just on the power strip? I mean, do you use the switch on the PSU, set it to Off, and then set the power strip to Off? I don't think you do that. wardog makes a good point about the surge, inrush current spike to a PSU.

As wardog said, I also do not turn off my power strips when I shutdown the PC. The amount of power being used by the PSU is very small, two Watts with a modern PSU. The +5V standby power from the PSU is only capable of providing 15W or less to the PC. My Kill A Watt power strip shows about 5 Watts for three PCs in Shutdown, S5 mode. I use multiple power strips, all with filtering and surge protection, the PCs on one strip, monitors and networks switches on another, and one main distribution strip.

Happy to assist Wink

As for the overclocking, your board is a solid one so in all likelihood you just have a poor overclocking CPU. My 6600k is also only properly stable at 4.4ghz, I can get it all the way up to 4.6ghz (like the validation in my sig) but it isn't stable and needs a lot of vcore. Overclocking is a very luck oriented thing, that is why some stores actually sell CPUs that they have tested stable at certain overclocks for a lot more than the retail value of the CPU.

Google "Skylake overclocking guide" and see if you can find any info you have missed. On my system I find the easiest way to overclock is to set one of the EZ-OC modes (usually the lowest one) then adjust the multi higher until it becomes unstable. Once that happens I bump up the vcore 0.05v and try again until stable or I get to 1.4v at which point I stop and back off a little on both the multi and vcore. I would start with a fixed vcore of 1.2v and say a 42 multi and work my way up from there. Setting one of the EZ-OC modes sets a lot of things automatically for you like short and long power limit, LLC etc so you don't need to think about them.

Good luck and let us know how it goes.

I am coming home right now. Will check cables, and connection without power strip and post results :)

Thank You guys

Hello,

MOBO model: AsRock Extreme 4 Z170

I really dont know that PC should be constantly on power. That's really weird for me. I was always turning off power strip. What do You recommend in that situation ? I will check in home all cables. Should I clear CMOS too ?

Basically just shut down the system and walk away, it's that simple Wink

The only time my systems are ever cut from the wall is when there is a thunderstorm or when I am away for more than a day or 2.

Thanks for posting the article link Wardog, I remembered reading it last time you posted it but couldn't find it to share here. A very interesting read.

And I should include that ALL computer power supplies are switching mode power supplies.

Important when digesting the article I linked of inrush current above.

It directly apples to all desktop computers.

That line above grabs my attention.

Let's for a moment not consider it a Power Supply issue but instead one of simply proper power.

What does your term "etc' consist of connected wise?

IMO you have too much connected to the power strip now, w/o knowing what that "etc' includes. If that includes a laser printer, all bets are off the table.

To test, pull the strip and all connected out of the wall. Now, with just the computer and essentials to operate it, plugged directly into the wall outlet(s) sans all that other hardware,, does the system behave the same or better?

Now let's move on to discuss the damaging inrush current that you are unnecessarily subjecting all the items connected to the power strip. An excellent article I post here every time I read of people cutting power at the strip instead of leaving their newer highly efficient computers in a powered down state.

http://sound.whsites.net/articles/inrush.htm

Leaving capacitors charged in a powered down state is far far better on parts/components than justifying ANY energy saved by doing what you currently do, flip the strips switch and cut all power.

Possible short term and definitely long term damage happens each and every time you flip the strips switch to On.
