Title: Overclocking S9i in relation to temperature?! Post by: MiniMike on November 28, 2021, 08:37:42 PM Hello,
I own Bitmain S9i, I'm under Braiins OS+ since the beginning. I have never increased the power beyond 1300w, for fear of making them overheated and out of order, since this summer it was running quite easily at 100% ventilation. But in winter my room does not exceed 10°C, and fans between 15 and 30%. Would it be dangerous to increase the power? Or on the contrary, would the fresh air allow a better regulation? Thanks Mickael Title: Re: Overclocking S9i in relation to temperature?! Post by: MiniMike on November 29, 2021, 03:48:41 PM What I was wondering is what is most likely to damage the chips?
Overheating due to not enough cooling? Or Over-frequency / over-voltage? Let's say I have an S9i with a power supply that could not be more excessive! "Like 4000w". Let's say that at 1420w it gives 16.5Th/s under Braiins OS+, air inlet temperature 25°C, fan speed 90%. Would the chips accept a setting of 2000w, if the air inlet was 3°C and the fans were at 90% ? Just curious, I don't plan to do this on my S9i! I was just wondering what would be likely to damage them first. Title: Re: Overclocking S9i in relation to temperature?!

As to what can cause it:Overheating due to not enough cooling? Or Over-frequency / over-voltage? 1. Insufficient cooling 2. OC/OV coupled with poor cooling. All OC/OV does is increase chip temperatures but provide enough cooling to make up for that and you are good.. Title: Re: Overclocking S9i in relation to temperature?!

So even if you increase the power and the voltage, theoretically there should be no problem as long as the cooling is optimal? Also I imagine that it could be reliable on S9, but much less on S17 Pro or S17+ ? |
