So as you guys know, Coffee lake processors are around the corner and you will need a new motherboard for that, one with the Z370 chipset. The Socket physically looks and seems to be the same, LGA 1151. As it seems only Coffee Lake procs will work on it, and not 7th Gen Kaby lake.

Dutch website hardware info actually put it to the test, they took at Z370 motherboard and dropped a Celeron G3930 processor on it. The processor is pin compatible, the system nearly booted, yet at in the self-test stages at VGA detection the boards keep restarting and resetting.

Now the conclusion from them is that the procs are not compatible, however if imho if the Celeron G3930 passes most tests in the BIOS post stage and simply reset at the VGA detection, well personally I tend to believe that it MIGHT be possible to get older procs compatible with new BIOS updates (if Intel allows it). I mean VGA is the last detection stage, ergo the CPU and memory at that stage already have cleared to OK status.

Time will tell ...
