Yes I have tried with 2 different chipset versions.Did you install chipset drivers, USB drivers and Sata drivers? Don't bother with the Raid Expert sata drivers, just the normal ones. Manufacturer of your board should have all of those on their motherboard page, probably under Support.
But you can also get chipset drivers directly from AMD. Manufacturers don't always update their site with the latest.
all connections are secure. Yes- 2 chipset driver versions.https://www.anandtech.com/show/12542/overclocking-the-amd-ryzen-apus-guide-results/7
You should be able to get to 3700 Mhz with 1.3 volts, lower that.
You did connect the 8-pin to your graphics card, right? Check all connections once more, even harddisks but especially power cables.
By 2 chipset versions you mean 2 chipset driver versions, right?
