My take on it is this, BD is a highly unbalanced chip so sure you might get 2 core 4 clusters to do 4.8 24/7 but the chance of running 4 core 4 cluster at 4.8 is slim to none. To do that we would need full cluster control and be able to deactivate cluster a and use cluster B if we wanted which currently is not possible.

I tested down to 4.5 4core 4 cluster and it was still failing prime versus 2 core 4 cluster doing 4.8 no issues..........could also be a bug in bios somewhere but atm that is wishfull thinking.
