How about a 3+2 phase with doublers?A 4+2 phase? Remember, that CPU has up to 50% higher current demand than the 1700 within the same power envelope, not counting AVX2. It also has a higher TDP and likely a lower "reference" voltage (not that modern AMD CPUs really have a reference voltage). If you are lucky, it'll be stuck at 3.8 GHz and won't try to boost anywhere.
I would worry about stock operation.
Hardware Unboxed ran 3900X and 3700X on an ASRock AB350M Pro 4. Stock works.
