Z370 Multicore Enhancement Voltage (8700K)

Hey there, folks. I popped in an 8700K into an Asus Prime Z370-A and so far things have been just ducky. Temps under the Hyper 212 Evo don't exceed 67 C at stock, so with that I'm pretty happy. Since I just have a 1070 I'm not looking to get into in-depth overclocking with this yet since it's pretty unnecessary, but I did tinker with the Multicore Enhancement feature present on Z370 boards to allow all cores to boost to 4.7 GHz and I've noticed that some of the cores' voltages can spike as high as 1.406v with this enabled.

 

Isn't 1.406v a little sketchy on Intel CPUs? If that's the case, I'll just leave it stock until I've got a real reason to overclock it manually. Maybe when I get a better cooler as Multicore Enhancement pushes me into the 70s with the 212 Evo. If that's perfectly fine, well, I'll just leave MCE on then.

 

Thanks in advance.

1.4 is boarderline cpu degrading, u should turn MCE off, and enter a manual voltage of 1.3v for 4.7 to see if it boots, then lower it til it's unstable then tune it back up.

It idles around 1v flat and under load hovers around 1.33-1.35v, but yeah it has the occasional spike to 1.406v. I know Ryzen can take that just fine, but afaik 1.35v was the max for daily usage on Intel CPUs.

 

I'll keep it off. Looks like MCE is a glorified auto overclocker.

i mean it won't fry ur cpu, but id bet that ur max clock would decline by 100mhz within 2 years, that's also insanely cool temps for a 212, but ya, ur likely fine if it's just random spikes to 1.4

That's what I thought. I thought that the 212 Evo would be pushing this thing around 75 C just at stock. Can't complain though.

I don't see the problem. Enable MCE, use manual voltages and drop the voltage until the system becomes unstable, then back it up a little -- you'll get both a faster system and it'll run cooler. I did the same and I even cranked the ratio up, netting a nice 200MHz up, too.

I tried setting manual voltage but it still spiked up to 1.4v even when I had the manual voltage set to 1.25v.

 

Any ideas? If this is just a symptom of MCE on my board I’ll just manually overclock later.

MCE's what's causing the voltage spikes.

Yeah, as I thought it’s a glorified auto overclocker.

 

I’m done tinkering with it. I’ll just overclock properly later. Thanks guys.
