Oh and I should mention that the PSU that this happend to was a Corsair AX860 which is likely made by Seasonic. I don't know the gauge of the wire they use but if I had to guess I'd say it 18 AWG.

 Strange :| I'm running a full rig @ ~570GHs off a TX850M and she seems cool as a cucumber.


But like I said I bet you did not make the mistake of running BOTH 6pin connectors off of the same main PSU 8pin PCIE feeder (talking about the modular plugs on the PSU itself) Essentially it's a splitter that converts 8pin to TWO 6pin. That is what I was using and that's a big no no. Check your total power usage and feel to see how hot the cables feel at the PSU end. That is where it will most likely melt the plastic around the pins.

I also observed a funny phenomenon where the system slowly overclocks itself. Essentially the resistance on the h-cards at the R02 resistor lowers itself with time. Don't ask me how this happens, but it may be somehow the way I pencil modded them? I dunno, either way I'm hoping that it will remain stable for now.

Anyways, wrong thread for this discussion.


Yes, that's true!! The R02 resistor lowers itself with time. I guess the hot carbon sitting in that resistor becomes more "resisting" over time?? I've consistently seen this effect as well. I used HB pencil. A good experiment is to use H2 or harder pencil to see if it has the same or worse effect.

Pardon my ignorance if this has been mentioned, but what exact corsair case are they going to ship babyjet units in?

How do you know they play nice with each other? Because they big volume suddenly drops after a big move??


not to derail this thread too much (on topic..why haven't Hashfast showcased their miner, actually mining?  Seems they have faith that their PCBs won't need to be tweaked at all...)


whales playing nice?  You can see rarely when they war with each other..  study the buy/sells and their walls (mostly fake ones)

As each day passes HF looks more and more as major failure. It may sound cruel for BTC community, but now I hope for temporary BTC price drop at refund time, so the refunds would have more value when issued. Even if HF cheats with BTC refunds and calculates them in US$ it would have less impact for the buyers.

 You get what you paid. It's even stupid to think that they would pay you in dollars at a new conversion rate since they took BTC when you closed the sale contract with them. Otherwise, expect a massive class action lawsuit since that'd be fraud. They have to return what that took from you. Did they took oranges or peanuts? No. So no need to worry about what's the current conversion rate with any currency. It'd be double stupid to do otherwise considering that the MPP is based on BTC return!! Not dollar returns.

2x 6-pin PCIe cables are used to power my Bitfury M board.  A few people have had their's go up in flames when using between 500-600w.  The three 12V molex contacts on the 6-pin connector themselves are good for 300W or so all combined, so long as your PSU manufacturer doesn't cheap out on them and use a smaller gauge than spec (which seems to happen on occasion).

It shouldn't be a problem if we're all getting seasonic psus.

Yeah, well the issue is that the bitfury team did not anticipate that people would overclock the fuck out of them and thus pushing power draw into the stratosphere. One of my bitfury rigs is drawing 470 watts from TWO seprate 6 pin PCIE connectors. Previous to that I mistakenly ran two 6pins connectors from the same main PSU feeder jack and guess what, the plastic around the connector melted. It was pretty much close to a complete meltdown. At the time the unit was pushing 528 gh so power draw must have been over 500 watts for sure. I can't for the life of me understand why they did not use either 3 separate 6 pin or 3 8pin just to have some headroom cause they should've expected people were going to overclock the units as soon as they found out how.

Oh and I should mention that the PSU that this happend to was a Corsair AX860 which is likely made by Seasonic. I don't know the gauge of the wire they use but if I had to guess I'd say it 18 AWG.

The point that I'm trying to get a cross here is that over-engineering something is a good thing when you can do it without an unreasonable increase in cost.

Also, damn this thread grows like weeds!

Charts still show a downward trend. It will take alot of buying to change it. If the market sinks below 650-600 even the western whales will sell with extreme vigor. I doubt the whales will sleep tonight.

the interesting thing is that there is no real way to resolve arbitrage quickly between the exchanges yet it seems many of the bots key off one another..  each exchange could have their own massive pump/dump (and a few times you can see it) but it seems the whales play nice with each other for the most part

this latest levitation from 650 turmoil to 750 rainbows proves a few things... hardly a fight, and hardly much volume.   Looked like trickle sells to the scared and soon the drop back....

Your wish for a BTC crash is coming true.

http://www.btc38.com/btc/btc_market/476.html

TL;DR : Investors got played to crash the price. Apparently *shrugs*

Weak hands got played. Gave people who have faith in BTC chance to get cheaper coins.
Don't be so sure, this is just the last peak. (IMO)

Do I read this update right: They've assembled 400 Baby Jets, but without motherboards in them? They have only 3 motherboards and waiting for the rest 397 of them to start shipping?

They’ve started assembling Baby Jets (overnight tonight). They aim by night’s end to have the first round of assembly done for 400 Baby Jets.

Hooray!   Cool
