Custom FW = Vnish = Fried chips. No thanks.
Vnish is not only custom firmware. Neither custom firmware nor Vnish's firmware indicate fried chips.
I am interested in machine if it is still up for sale. Also interested in knowing which firmware is it using.
That's interesting, because I repair Bitmain Chip boards. 98% of the "fried chips" I encounter ( and I encounter a LOT )are OC'd units and Vnish has 95% of the OC FW on the street these days. Lastly, almost ALL boards that run Vnish FW sustain excessive heat damage. " ALL ". But hey...What do I know. At least he will stand behind his product and warranty it.....oh wait....that's not true.
Having any custom firmware does not mean you have to OC the machine. Also, no one can give you warranty for overclocking, does any CPU manufacturer do that? NO. Does Bitmain? NO. How do you expect any FW maker do give you one?
OC-ing that hard to break your gear / fry chips is not problem of a FW maker, it's user stupidity and nothing more or less than that.
You cannot blame a car manufacturer if you hit a wall with your car on purpose, that is not how warranty or blame in that matter works. Actually, you can blame car manufacturer, but you'd just be plain stupid in eyes of many.
You are doing the same thing.
I will put an end to this conversation here. As any educated user who tried a lot of firmwares and knows what OC-ing (and UC/DC-ing) is and how it works, will know what I am talking about.
This thread is not a place for this anyway.
