@polo Am I reading this wrong? 5.2Ghz under 1.280v? What is the 4800Mhz, 4500Mhz next to it?

What about the voltage? Are they really getting 5.2Ghz under 1.280v?

It is possible, but it all depends on silicon quality and cooling capacity. Ambient temperature also plays a big part.

With the room temperature at 20°C my 8700K can run benchmarks at 5.2GHz 1.415V without any issues, but with any higher room temps I get WHEA errors.

Here are screenshots of the 5.2GHz OC I did this morning with the room temperature at 25°C. I chilled the radiator with ice water and lowered the Vcore to 1.380V. No WHEA errors.

@polo

Do you pay any attention to WHEA Event 19? I could never really determine whether these were overclock related or not...

I regularly check for WHEA errors. If you get WHEA errors you need to raise the Vcore. In the winter I can run the 5GHz OC at 1.296V, but now with the higher summer temps I had to increase the Vcore to 1.312V to prevent the WHEA errors.

So the Corrected Machine Check WHEA's are usually too little voltage? Looks like I need to bump up a little.

Yes, raise the Vcore with 0.010V.

Alright. Damn I was enjoying the -2C drop, oh well no biggie.

Interesting new function(I think it's new as I never noticed it before) in CPU-Z.

If you run the Benchmark v.17.01.64, you can submit and compare now.


Mine with 5.3GHz(click score at bottom left to see comparison): Intel Core i9 @ 5298.73 MHz - CPU-Z VALIDATOR



I got top score for single thread: CPU-Z Benchmark for Intel Core i9-9900K (1T) - CPU-Z VALIDATOR



And not bad for 16+ multi threaded(until more users post their results anyhow): CPU-Z Benchmark for Intel Core i9-9900K (16T) - CPU-Z VALIDATOR

Well at only 5.0 right now, yours is a lot better score than mine Cliff ...
