The Curious AsRock MB

This is not so much a question as something i recently found out. My old AsRock z170 pro4s seemed to work just fine. It was able to overclock my i5 6600k and rarely had any issues.

There was one quirk however and it had to do with how it interacted with my i5 6600k. One of the cores( the second one) was always anywhere from 4c to 8c higher then the rest of the cores. Of course the first thing I thought was I has set either the heat sink incorrectly, or had not applied enough M4. This was on an H80i thought i should mention this. To be fair, I was able to put a modest overclock of 4.2ghz on the cpu without raising the vcore. I could have gone higher . I know this because for kicks and giggles put a stable oc of 4.5ghz with a 1.385 vcore. However that one core would climb into the 70s celsius. The overclocks where not too bad for a 100 dollar motherboard.

Recently I bought a new motherboard. An MSI z270 SLI. I also bought an H100i v2. I did get the cooling first and tried it out with the old motherboard. I was having the same temp issue. On the new motherboard all 4 cores stay around the same temp. There is no huge fluctuation with one core.

I think that the AsRock motherboard was somehow throwing more juice onto that second core.

On this motherboard I get a stable oc of 4.5ghz. at 1.375, with temps at load about 60c.

Not quite sure what your talking about. The point was that the AsRock mb was throwing more juice on one of the cores without my singling it out on the motherboard. Causing it to generate more heat on that core then on the other ones. I was not looking for advice on what motherboard to use. i was simply making an observation that this particular motherboard was not distributing power to the cpu cores evenly. Since this has not happened on any of my many builds I thought it worth mentioning.

I am quite happy with my new MSI z270 SLI. I have used Asus, Gigabyte, AsRock, and now MSI. Of all the builds I have made,Asrock has always seemed to have the worst qc. That is not to say they are bad boards. They are not however the best boards for overclocking. Though they do overclock and have gotten much better over last couple years. I have never had any issues with any of the other manufactures I have mentioned. Heck that board still works and i will keep it and maybe make a build for a friend of mines' child.
