Specifications and Stability at Rated Speed
The C7Z270-CG is supporting every available processor for 1151. It will probably change in some time when on the market will be the Intel Coffee Lake series. Rumours say it won’t be compatible with the Intel Z270 chipset but hard to say if there will be any way to make it work with new BIOS release. Time will tell while now let’s focus on what is available.
Supermicro C7Z270-CG also supports RAM up to DDR4-3733. However it doesn’t mean it will work with every memory kit using XMP profiles but about that I will tell you some more on the next pages of this review. Settings up to DDR4-3200 are working with every memory kit I was testing.
My friend asked me if this motherboard is supporting SLI. Looks like yes but there is no clear answer in the manual where we can find description that this motherboard supports multi GPU configurations. AMD CrossFire depends on used graphics cards so will work for sure. SLI should also work especially that in the box we will find SLI bridge which suggests compatibility.
All tests were performed on the i7-7700K processor. As you see on attached screenshot, there is no issue to keep it at 4.5GHz and default voltage when we enable high performance power mode in Windows.
I’ve seen some reports in online stores about issues with 1.0 BIOS/UEFI and processor frequency was clearly not true. The C7Z270-CG has absolutely no issues with stability and is actually really stable motherboard which I can compare only to the best ASUS and ASRock motherboards ( which also cost more ). As a comparison I’m using ASUS APEX Z270 motherboard which is top overclocking platform for Intel Kaby Lake.
Below you can see screenshot from AIDA64 stability test. No issues at all.
BIOS/UEFI can be a bit weird if you are moving from more popular ASUS, ASRock or MSI motherboards. However there are many options which should satisfy even more demanding overclockers. If we compare available options then it’s close to what we find in ASUS ROG series. For sure a lot of options to play with.
What more, the same view as in BIOS, you can see in SuperOBooster software. Below is screenshot so you can see it. All options seem to work what I can’t say about competitive applications. After switching some of the options is required restart but that’s normal.
BIOS/UEFI is in 1.0c version which is the only available. Because of that we couldn’t check how BIOS update option works but it’s available from UEFI and Windows application.
On the next page there are screenshots from BIOS.
