ASUS Prime Z370-A Motherboard Review

Overclocking on the Z370 platform is pretty much the same as Z270. You’ll just need to set your BCLK and CPU core ratio. The only real issue with this platform right now is that these chips get hot, real hot! For those who are new to overclocking ASUS has a 5 GHz OC profile you can simply just load.

If you wanted to manually overclock in the BIOS yourself just set the BCLK frequency to 100.00, the CPU Core Ratio to Sync all Cores and then the ratio you want. We are shooting for 5.0 GHz on our Core i7-8700K so we set it at 50.

You are probably going to want to set your own CPU voltage (Vcore) as well. If you have it set on auto it is going to want to push more voltage to the CPU, which will result in higher CPU temperatures. We set ours at 1.30V.

So 5.0 GHz was a stable overclock, but barely. Our cooling solution was a NZXT Kraken X52, which is a pretty great AiO, but running benchmarks or our stability test our CPU temperature was around 90C, which is a little scary. Of course de-lidding your CPU and using liquid metal could help with temperatures, but if you plan on running a 24/7 overclock on a Core i7-8700K you are going to need some serious cooling.

    Enjoying the review so far, thanks! I have been a fan of the Asus boards for a long time. This is my choice for the Coffee Lake system. I don’t need WiFi on my desktop and the ROG bling never really thrilled me. I want good power stability and a reliable board, this seems like one to use.

  • Thanks for catching that! Yes this is a very solid board!

    perfect reviev.
    This is my choice .Briliant price and nice design.My question is about power section-how much power phase is on the board?
    Finally ,power section is ok?

    Thanks a lot I’m getting this board too. Dam good review. So if I get a 8600K with this board I can use a OC profile and easily OC to 5.0 also ? If yes that’s great I’m just done with manually OC’ing CPU’s these days, I just don’t have the patience anymore.

    By the way when you OC does that automatically disable the turbo ?

    Last question Bob “the six SATA 6GB/s ports” are controlled by Intel® Z370 Chipset right ? Cause on the ASUS website in the spec section it doesn’t say.

    On overclocking I think you may find that you are better served to do it yourself. From what I have read the boards tend to apply very aggressive voltages, to the point where it may be stable but the cores are being fed much more voltage than is necessary. You can try using the XMP setting for your memory and leaving Multi-Core enhancement on, but I would run a few stress tests and monitor the voltages on the CPU to see what the board’s auto settings are doing. The MCE basically runs the CPU at all cores max Turbo for all tasks, so it disables the scaling Turbo.

    Since I decided on this board too, I did quite a bit of reading up on the VRMs, general stability, and OC ability of the board and I am happy with my choice. I would not buy a board for overclocking without VRM heatsinks, and this board has that covered. All in all a good looking board from my point of view.

    Well here’s the thing like I said in my post I don’t have the patience nor the time to be testing out overclock settings anymore, either I use the overclocking program or I don’t do it at all. In the review the guy said he had no problems with the automatic overclock. What do I care if if it’s using a little extra voltage an extra $2 a year in the electric bill?

    A shorter cpu life span

    Hi, Can I used this motherboard for mining?
