i7-8700k OC Help

13 minutes ago, ManDownUnder said:

I turned LLC to High but got BSOD non stop. so increased Vcore to 1.35 and no bsod atm but still got vin 1 and vin 2  2.016 V

This is fine. Anything under 1.4 is fine. If you can get that stable with moderate levels of LLC, you're good.

 

Anything under 100c in a full blown stress test is fine.


Your cooling is good. The only thing you can really do to improve things is to delid. Which I did and helped a ton.

Hey guys.

 

I have a question regarding overclocking my i7-8700k to 5ghz on Z370 AORUS Gaming 7 and H115i Pro Corsair 280mm AIO.

Currently i have OC to 5ghz with 1.310 V and LLC on Turbo.

It seems to be stable but im hitting 90c on some cores during  Cinebench test. When gaming it doesnt even fo over 75.

I am able to crank case and cooler fans to 100% and i get about 85c during the test but not putting up with the noise. No load temp is 25'c-30c with heater on.

 

Will these temps be okay?

90c is on the higher side of things. But since it's a stress test it always will be pretty high. If the temps are good under your normal workload then that's fine.

Looks normal for aio stuff. I dont care for stress tests temps. Only real world matters to me.

Your cores are hitting a maximum voltage of 2.0V! That's terrifyingly high! I very, very much recommend you find as low LLC as you can that's still stable, because with LLC set at Turbo, your cores are getting way too much voltage.

Could this be a problem with HWmonitor readings>?

That's very likely just a false reading - if the Vcore actually hit 2V then OP would be looking at a fried CPU.

 

Regardless, I agree that dropping the LLC down would be a good thing to do to drop those temps a little bit.

You can always try e.g. HWinfo64, which I use, if you like. That said, no, I don't think those readings are wrong.

were does it show VCORE on that program?

After dropping LLC to High and increasing V-core to 1.35v getting lower temps in the 80's now during cinebench. I watched the V-core on CPUz and it didnt go over 1.272v.

 

Vin 1, 2 and 3 still really high

Okay. i'm so confused. Werecatf said these are correct readings. but after doing some research i found that VID is NOT a voltage. It's just a value sent from the CPU to the motherboard. Ignore it. Is this correct?

VID is what the chip is requesting, not what it's getting. Look for the VR OUT reading, if you can find it, that will be the most accurate. Otherwise there should be a VCORE reading somewhere under the motherboard sensors.

Thanks Mr Woof. that previous information had me worried for a moment there.
