Bitaxe Supra Hex 701: Power Fault at 4.2TH/s Overclock (Solution Found)
Hi everyone,
I want to share my experience with the 'Bitaxe Supra Hex 701' while trying to push it to a higher hashrate.
My setting was Freq/Vol 550/1200 (exp hashrate 4.21 TH/s),however the miner started showing "Power fault detected"
I then switched back to the default parameters Freq/Vol 490/1166. It can go 3.75 TH/s stably.
After checking the hardware, I suspected the issue might be related to VRM. I added small heatsinks directly on the inductors, and after that everthing goes well.
My guess is that during high-frequency operation, the inductors were overheating or experiencing increased power loss, causing the power protection circuit to trigger.
Has anyone else experienced similar issues with Bitaxe Supra Hex 701 when overclocking?
