B450 GAMING-ITX/AC, Ryzen 1700X reboots under load

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My system reboots after 3-5 seconds, when I take full loat at the processor in 7-Zip benchmark or OCCT 4.5.1 stress test cpu. My configuration below:

Operation system: Windows 10 October 2018 x64
Processor: AMD Ryzen 1700X
Motherboard: ASRock B450 GAMING-ITX/AC
Memory: G.Skill Aegis 16GB DDR4 16GISB K2 (3000)

Temperatures in HWInfo normal, power supply 450W Silverstone. System tested with Thermaltake 750W. The same reboots.

I understand, that my memory not official supports by motherboard, such as 3000 MHz frequency. What can I do, to use it? I tried to take lower frequences, include it's native 2130. But it doesn't work still.

Have anyone decisions?

	Put the latest BIOS (being it even a beta) and then clear CMOS. Try again with the XMP profiles. If this doesn't work, you can check Internet for guides for Ryzen DRAM calculator and Taiphoon Burner.

	I have 1.70 BIOS. I don't clear it, but set to defaults. OK, I'll try to clear CMOS, but don't sure for a needed result...

	I think, this motherboard doesn't real support Ryzen 7.
