Today, we have published an Intel X299 Micro ATX motherboard test with a sweepstake on OCinside.de! After the recently released AMD Threadripper Micro ATX motherboards from ASRock we have the Intel X299 Micro ATX tested today. The new ASRock X299M Extreme4 not only offers great features like three PCI Express slots, two Ultra M.2 32Gb/s slots, eight SATA3 ports, etc. but even has some more unusual features like the OC header. What this means and how the X299 Micro ATX motherboard from ASRock has scored, we show in the following review, as usual with high overclocking, benchmarks, 360 degree view and thermal images.
