Sorry about that Gator.
Specially for customers like you we are finishing now 4 chip version with normal heat sink and fans.
I hope it will be stable @ 130 range  with nice 2-3w fans.
The damn chip is sooo power hungry

Update in Monday


This is great  Smiley
I am sure many people will choose 4 chip version  Grin

Are these A1's chips a different production run to the ones Bitmine are using? How did they manage to get 1GH/1W?
What about the Bitfury 2, is the ETA for that still March? I'm probably just going to wait for another chip.
If I cannot get these running quite I'll eBay them.
If someone can give me the lowest GH/Watt they will run at it would be useful before I pick up a temporary PSU.
But if not I'll find out tomorrow and report back!

They use more chips at slower speed to save power.

Yeah I thought they used 12 instead of 8, but someone corrected me on that, the 12 is for the Rig, the desk has 8, like the Hex8A1.
The chip specs say 850mV for 1GH/W, which was supposed to be their Turbo mode, so I'm surprised these don't even fire up at 850mV.
I did hear a rumor they made a second batch and the first went to DIY, but I was hoping it wasn't true. Tongue

No I mean in total, don't they have 5 boards in the Desk? So for 1TH they are getting 200GH per board which is much lower than the 270 these ones get so maybe needs less volts.

they have problems with power dude. They can not meet promised/advertised power consumption and 100% of US citizens home fusees are going to explode Grin Grin Grin Grin Grin
Az zich posted chip is not working at lower voltage. I do not know if it is because of the chip or because of the design but i guess it is a chip to blame.
Besides it is getting very expensive when you switch cheap PC PSU with industrial one Grin
Can you imagine to tell your wife
Honey i got new miner.
That is very cool we are gonna be reach
Yes..Probably maybe but please, please stop using washing machine, oven and air conditioner Grin
I can not especially today Grin
