I may have accidentally set my bios on a b350 tomahawk to clock my 1600 at 4.2 instead of 3.2. There is no display output but power to my peripherals. What do I do???

Clear CMOS / RTC. That'll reset BIOS values to default.

Main rig: i7 8086K // EVGA Z370 Micro // 16GB Gskill TridentZ 3200Mhz CL14 // Sapphire Pulse RX 7800XT// a variety of noctua cooling // Corsair RM750x v2 //  Fractal Meshify C

Secondary rig: R5 3600 // MSI B450i Gaming Plus // 16GB Gskill FlareX 3200CL14 // MSI GTX 1080ti Gaming X // Cooler Master V650 // Fractal Meshify C

Audio setup: Audient iD4 // Adam A7X // Sennheiser HD 650 // Sennheiser HD 25-II // Audio Technica M50x // Sennheiser Momentum 4

How? There is no button on the I/O Shield like on STRIX Boards.

Resetting BIOS to default values

 

1. Power off the computer but DO NOT unplug the power cord (system under S5/ Soft-off mode).

2. Use a jumper cap to short JBAT1 for about 5-10 seconds.

3. Remove the jumper cap from JBAT1.

4. Power on the computer.

If all else fails, turn off, unplug, pull the onboard battery for a few minutes pop back in and you're good to go.

Popping battery is IMO best way. You will need to go for board with jumper anyway. Switch or button would be better, but can also cause issues. Like pressing it accidentally when re-routing cables.
