What, 15,300? Yawn.... Wake me when it hits 10k.

Indeed. I get to raise my prices for mining repairs. About time....

Eh, everything seems to be imploding. People buying Lambos for Christmas....

You got to admit though, they made some pretty good hardware with the Titan. The fact that it's still profitable is quite frankly amazing....

Sure. Being in China, they are exceptionally difficult/impossible to sue. Many mining companies had lots of lawsuits and sometimes I wonder if those were funded by other mining companies, leaving bitmain....

They also actually delivered product although the recent quality seems to be.... poor.

Now you have me thinking "Schroedinger's Troll". But yes, these fees are getting stupid. Maybe it's time to boost the blocksize......

This has nothing to do with a mining monopoly. Limited space, lots of people, slots go to the highest bidder. What would be better, random choices of what goes into the block, or bigger blocks which is called um... btrash.

That could be it: I picked up some S7 parts today from a guy who was telling me a new batch of S9's was on sale for 2400 or somesuch. Maybe everyone had to buy crapcoin to get them.

Check the voltage when the unit is up and running from ground to one of the ends of the choke coil. If you see about 10.6v then the power supplies are good. If not then the chip may be out.

Need to see if there is an exact replacement for this oscillator; the ones I am swapping in might not put out enough power to run the chips. Hm....

I meant it's a few days to a week for my repairs. China could be anything......

Meantime I'm having fun. I think Antminer used some crappy oscillators.....

Hm. Sort of works. On this board I'm testing I now can hash at 125mhz, but it says only 21 chips are there. Which might mean the crystal/oscillator I'm using doesn't have enough power to run the string.

It's the little silver thing with 25.00 on it between two chips right above the inductor. Can't miss it. Getting it off without knocking off a heat sink is an exercise, but I have something that does work here (albeit slowly).

So I might need one that takes a different input voltage or can drive more stuff. There are several crystal pads on the board, but only one is used. Hm......

With BCash you're trusting Antminer corp with your money, where they can fork and screw as they wish.

Oh I don't know, I was never a fan of company scrip, but YMMV.

Ok, so at what point does all the hash power go to bitcoin trash and so forth?

I don't know for bitmainrepair, but for myself it's usually a few days to a week for turnaround.

Yep. On the bench that's about right; if you take a voltage reading with the boards in and plugged into the controller it should be about 10.5 as 8.mumble is the default on the power controller chip when it's at idle. So that's working.

I'm leaning towards the wrong firmware: You have the later firmware on the board which works with the same boards I have in my unit (1.31) with the slightly different earlier firmware. When I get a chance I'll reflash mine with the later firmware and see if it runs my later 1.81 boards, I'll guess you need the other firmware to run 1.11 boards and 1.31 boards work because I'm using it.

Do the logical dance....

CC

Indeed. If only there was a solution for this.... And even with these fees it doesn't make up for the 25/12.5 halving....

Still stuck at 19k or so. Blah....

Worst case you can send it over here and I'll test it on my default rig. Maybe it needs a different code version, but this is not the first time I have heard people say it doesn't work with all three boards at say slushpool. That makes very little sense (unless it is secretly mining bitcoin trash/cash and Antminer is paying out in bitcoins. HMMMMMM)

Well it's one of my control boards for testing, so I'll see if I can get another board working first as a stable control. Issue might be with firmware, as there are two unique firmware versions from Antland for the S7/700/45 boards. I'll try that this week in my spare time.

Meantime check the voltage from the inductor to ground on the PCIe plug for the errant boards. A working board will read about 10.5volts to ground from either pin on the inductor, if yours reads zero it's not a bad fix. If you pull the board out and bench test it without a controller it should read around 7 volts.

I wonder if they would be profitable at current mining rates.... Monarchs are, which is beyond insane as are Neptunes. Maybe an underclocked chili could do it. Maybe I should dig mine out and stick a water block on it to see what happens......
