Whatsminer M30S over voltage situation
There’s a Bitcoin mining farm where we have a 1500 kVA transformer. When it was delivered, the highest voltage it gave us was less than 220, so it wasn’t working for us. The highest voltage it gave was around 210. Now they returned the transformer modified, and now the lowest voltage it gives us is 242. If you switch to tap 2, it gives 247, tap 3 gives about 255, and so on until about 280. So my question is if I can do overclocking on—these are Whatsminer M30S, around 88 terahash average. I want to know how much voltage the PSUs can handle without damaging them too quickly. I know they will wear out using them above 240, but what’s the likelihood of them failing? I have really good ventilation—it’s a container on top of a hill with a lot of airflow, so I’m not worried about temperature. I also have air injectors and extractors if needed, so temperature isn’t my concern. What I’m really concerned about is that the voltage limit for Whatsminer PSUs is 240, and I’ll be running them at around 242. But it could go up to 260 or so. My question is, do I need to raise the voltage to overclock? And will the PSUs handle it, because we really have no way to lower it without sending the transformer back to the plant, and we’ve already lost too much time on this farm. That’s my doubt.
