It appears when running Prime95 on specific FFT sizes, while it's forced to use AVX instead of AVX2/FMA3. As it's written in the thread above, FMA3 has to be disabled.
As there will be a BIOS fix, it could be power management related (voltage/frequency) as this might cause calculation errors. If this is the case, Skylake users in this forum might try to provoke such errors by applying slightly lower voltages or higher frequencies.
