I have Intel E5-2687W v4 CPU installed into 4028GR-TR BIOS v2.0a (7/27/2016).
But, after power-on the system hang at code 79 in Supermicro logo.
This failure solved by switching CPU to E5-2620 v4 or E5-2609 v3. Please advise, thanks.
Beta BIOS v2.0a (12/22/2016) can solve this issue, please contact our Technical Support for it.
