In MSCONFIG you can change this to 8 if you wish.

Be sure your BIOS is correct and motherboard and possibly CPU drivers are up to date. These are from your motherboard maker, not Microsoft! Folk are still trying to get by with Microsoft's poor broken driver update. Hey, it doesn't work for most of us.

https://community.amd.com/thread/215122 kicks it around more. I think in this case if MSCONFIG along with BIOS updates and settings doesn't cut it you have to ask the motherboard maker WHY?
