Today we test a very special Intel LGA1151 motherboard at OCinside.de. Skylake supports DDR4 memory modules. Anyway, there are certainly some users who like to install, at least for some time, their DDR3 modules. For this reason ASRock offers this new H170 Combo motherboard. The ASRock H170 Combo motherboard can be equipped optionally either with up to four DDR3 modules or two DDR4 modules. We have tested both and done some benchmarks with two DDR4 and with two DDR3 memory modules. In addition, we will show a direct comparison of H170 vs Z170 to see if you should buy the H170 or Z170.
