Is there way to set single-core precision boost limit over 4.5GHz?

Which would be the optimal PPT, TDC and EDC limits for the TRX40 Creator 8-phase 90A power design, if I like to set them manually? I have Corsair 1000W AX (CP-9020152-EU) PSU: +3.3V: 25A +5V: 25A +12V: 83A -12V: 0.3A +5VSB: 3A

Seems it does not hit even a near PBO limits with single-core boost. So, what else could be adjusted to get single-core boost over 4.5GHz?

With the AUTO settings: BIOS seems to set: TDC: 620A EDC: 670A PPT: 1000W But in the practice from those limits are used only: TDC: 18.6% EDC: 39.3% PPT: 20.3% and the single-core boost keeps hitting to its 4.5GHz barrier:  With the water cooling single-thread application is barely raising the CPU temperature and PPT, TDC and EDC has still about 60% room before the limits. So how to allow BIOS to OC single-core boost e.g. to 4.8GHz? |
