I need help over clocking.

[Silvasamuel13]

Ok so I recent built my first system and I want to overclock, and I am really lost. I looked at some tutorials and honestly I got kind of lost seeing as they used a different mother bored than me. A more in-depth explanation would be very appropriate and needed.

 

My system includes a core i5 8600k, ASRock Fatal1ty z370 gaming k6, 16g ram, and a Noctua NH-D15

Do you see OC tweaker in the BIOS? It's on the top half or the sides, as a 'category'.

Yes I do

Select that, you should find the core ratio below. That's related to MHz (45 core ratio = 4500MHz)

Sorry, I took so long to reply, and I found core ratio what now??

Before overclocking, make sure you have HWinfo, Prime95 and AIDA64 ready for use in Windows.

 

change the core ratio to whatever number you like. Core ratio x 100 = Final frequency in MHz. I'd try something conservative like 48 from the start, and let it boot into Windows. Start HWinfo and watch the Vcore / CPU core voltage and CPU temperature of individual cores (there should be 6 readings, from Core 0-5), and run Prime95 in large FFT mode. Make sure the voltage doesnt go past 1.4V and temperature below 80C (for daily use) or 90C (for benchmark attempts). If it passes Prime95's test for 5 minutes while the core voltage and temperature stays safe, you can overclock more. If one of them are too high, you need to lower the voltage. If it crashed, you need to increase the voltage.

 

To change the voltage, get into the BIOS and find the voltage settings (should be in OC tweaker). Change 'auto' to 'adaptive', and enter an offset number below. Positive numbers raise the voltage, negative numbers reduce the voltage. I suggest adding/reducing voltage by 0.01V each time.

 

If it crashed and you can't get into Windows or the BIOS, reset CMOS. There are multiple ways, like shorting the two CMOS reset pins (I use a screwdriver), taking the battery on the mobo out for a minute etc. Follow your motherboard's user manual instead.

 

If the system is stable (passing Prime95) without touching the temperature and voltage limit, you can overclock more by raising the core multiplier by 1 and things repeat again. Until the system crashes with that multiplier unless you allow the temperature or voltage to get past the limit, that is. In that case, drop the settings to the last stable setting and call that job done.

Thank you so much, i will be sure to update you on my progress.

So I ran into some troubles, first off I got to 5.0 Mhz and I tried 5.1 and my system, completely crashed. I rest the CMOS and started again, all of my bios setting had restarted so I started again. Now after a little, while my core will drop below 3 MHz and stay there even hitting 0.0 MHz.

Was 5.0 stable? What voltage did you try 5.0 and 5.1 at? What's your ambient temps?

5.0 was stable, I set my core voltage to 1.35V. I ran the torture test for 5 mins and everything was fine. 5.1 didn't boot at all, I didn't and haven't changed the voltage and my ambient temps were around 63C.

Run AIDA64 for an hour at 5.0 Ghz and see if it remains stable. Try 1.38-1.4v for 5.1.

Ok I will try that but what about my fluctuating core speed, after I ran a test or even after a while my clock speed will drop

Clock speed drops like what you describe mean there's some throttling taking place. Either raise your cooler's fan RPMs or reduce voltage and re-test the OC.

When I asked what your ambient temps were earlier, I meant the temperature of the air in your room. Warm air doesn't allow nearly as much heat to diffuse off of a heatsink as cooler air. This has a surprisingly large impact on overclocking stability.

OHHH ok so the ambient temp ( from what the thermostat was showing) is 79F, I have since lowered it to 76F. I also have a ceiling mounted fan at full blast with a window open. The room feels pretty chilly.

Lucky SOB. It was 105 degrees outside today and my air conditioner is broken 

 

My room's probably a solid 90+ atm.

You would be dead now.  Ambiant is what the room temperature is.

I wouldn't really call my lucky I mean I am still working in the fields in order to pay off this pc and my fans are at full speed inside of the bios so I will try to lower the voltage

Fair enough then. I work as a helpdesk support in IT... so I'm in a highly air conditioned environment all day

Then I guess you would be the lucky SOB, anyways I lowered the voltage to 1.310 and it is typically around 1.285V and yet the clock speeds are dropping... I should probably put the side panel back on.
