i'm a bad idea.... in the cgminer source for d3 if i delete xcoin.c and rename groestl.c in xcoin.c and recompile soure of cgminer, put it in the firmware and run on my d3 .... what's is the result? @blissz can you prepare it for me and i want test... thanks

First of all, thank you Blissz for the work. My first message here at bitcointalk, cheers!!!

Is that normal having a hashrate of one board disappearing and coming back all the time?

The power usage still same when it happens but as I am mining in nicehash and when I see there is a decrease in hash rate also on their dashboard, what can it be? I am running my D3 at about 9500Gh/s(only two chains) as I am using a pc PSU while they ship APW3++.

For Extreme performance that use power up to 1400 watt : If I push my room temperature to 10c, can I go further ? Let said YOLO performance ? So Im not wasting the 200 watt left in my PSU. Anyone done this ?

@Blissz, I am a hardware/firmware developer. I got the wild notion to inspect the processor board and found it to be a Beaglebone_black_v2.3, my version anyway. I went to Beaglebone.org and found the specs. This D3 version is missing some crucial parts like the usb, buttons and some other chips.
Here are links:

Now here is the internet bomb:
We all know or should that there are threads about the D3 explaining Bitmain's use of the D3 to corrupt the market against any competition. Whether this is true or not it stands to reason that the greedy operate this way. So I gave it some thought and here goes:
How could BM impact the market quickly and most efficiently? Simple repackage an existing product and the clamor of the market would make the necessary statements to promote the 'NEW' product which the public did. In this case BM didn't have to lift a finger because of the trust and product effectiveness that the S series products had gained in the market. The trap is set.
How did BM get the D3 to market? We look at the runtime specs. Fans are loud, the hashing advertisement is high for x11, the speed is high. But the overall performance / profitability is negative in most cases. Any country that has high utility prices is not a great home for these units. My suspicion is these are S9s or lower and reconfigured for x11 with a conversion routine. And why not? Nicehash, Zpool, and Prohash do it! Right?
Repurposed S7s or lower would make the best sense. Keep making lower hashrate boards and plug and play. Who would know? With the conversion the high hashrate BTC boards would easily perform the task AT THE COIN RATES THAT EXISTED AT THAT TIME. They don't perform at the time of this writing but as I said 'THE TRAP WAS SET' and purchasers are screwed, the competition is dead and the market has consumed up any single unit purchasers from ever continuing.

Two things pertaining to the hardware. I have a D3 off grid right now and an S9 on grid that I will be moving in a couple of days so I will have a look at the hash cards for similarities.
After that, if I notice that the boards are the same I will order a Beaglebone black from Beaglebone, flash and MSD image, install and try it. It cant hurt. If this works then this will be a start at opening the platform.

There is a thread about one of the developers modifying the Bitmain software but he has since disappeared.

I am open to any thought on this...

We need to pump the Helium x11 coin when it comes out as the greatest coin ever

or

We need to make out OWN x11 coin..which is dubious at best an idea.....perhaps call it FUbitmain


(Well, hell, I can always use it as a 'space heater' in the winter or in the summer as a 'doorstop' ..er wait ..I have 2....DAMN IT)

I was playing with the chain a bit but when i change voltage of 1 chain it somehows affect the others to and i get HWS / high temps ? MY current voltage settings are 20 on all chains , i tryed nearly all of the  high combinations this one seems to be the most stable with 4-7 HW for hour on middle chain as i said only things that worries me is the last chain with 77 degree atm,   Might aslo meantion my D3 is in ventilated room with room temp around  0 degree

a really nice overclock. What are your voltage settings? Your temperatures are perfectly fine. I can't give you any guarantee, but if you have cheap electricity and can handle the noise I would let it run at these speeds.

If you're worried about the last chain, you can clock that chain down a bit to i.e 575 Mhz and lower the voltage a bit too to get it to ~73 degrees as well. Let chain 1 and 2 run at the settings as they are now.

Well this looks my stable peak  - https://imgur.com/a/v7X9J  im worried abou that last chip having 77 temperature do u think it will be alright ?

Could you do something similar for L3 +?
