Intel’s Skylake processors overtook the CPU market by storm this past fall offering better integrated GPUs than before, more performance and 14 nm technology but unfortunately for Skylake users Intel has found a serious bug inside the new chips that can lead to system freezes under certain circumstances. This unwanted behavior has been observed while running Prime95 but there are other programs that may suffer from CPU crashes.
Intel has officially admitted the issue saying that in certain highly specific workloads Skylake processors can hang or cause “unpredictable behavior”. Fortunately the issue has been identified and Intel has even released a fix that should arrive to you in the form of a BIOS update. So check the web site of your LGA 1151 motherboard manufacturer on a daily basis for the fix and then apply it to enjoy your Skylake system to the fullest.
