has someone figures about max. chip temperature of Jupiter October and November batch. did Jupiters died because of to high chip temperature?
85C is top recommended max operating temp. I had some hit 95 and survive just fine(not recommended)
Every board I had liked 75-80 for optimum performance.
Some say chilling works, but most of them have never seen 80C on their ASIC temps. If it were a GPU...
I'd say "cool it", but a Jupiter likes it toasty on the asic.
CLEAN power was most important..... meaning no spikes and fluctuations in the electrical feed.
also... tuning suite.... LOWER the voltages instead of raise to wake dead dies.Must be something about the way they do the calculations
Bitfury chips are the same way, only it's the hashrate rather than dead dies. If I push my rig's voltage, it hashes steadily, but at a bit lower rate. I undervolt it a bit, and I get some REALLY high spikes and overall higher hashrate, but it jumps around like mad. Over a 24hr period, though, I get more hash for slightly lowered voltage. Too far and it goes the other way. Finding the sweet spot is a bit of a challenge
As to cloudmining, I am doing it, and I'm doing well on it. Like most things, it pays to put your eggs in several baskets. The advantage of the mining contract is obvious, I don't have to hassle with equipment or pay electricity. The price I pay is about what I would pay for an antminer, PSU, and electricity at industrial rates, except that I pay it upfront and the electric would kill the ant in short order, whereas with the hosted mining, I don't have that risk.
On the other side of the coin is several factors that are important. I can tweak my hardware. I can mine alts, which if you play it sharp are more profitable. (sometimes. Yesterday I made nearly twice what I would have mining BTC. Today I'm at about 75%). I have the hardware in my hand, thus have total control over it.
All in all I prefer having my own equipment, but I will go both routes as it makes economic sense to have multiple income streams.
