My miner has passed the export scan. Yessssssssss....

I know someone mentioned about the FANS, question: What is the RPM of this fan in the unit? From researching this before, they do sell higher RPM fans, like 2000+ RPM vs. 1200 RPM fans of the same size and the same voltage. Do these fans have the typical 2-3 pin plug, or would there be soldering involved? If its not obvious, the higher RPM we can make through that tunnel, the faster the chips would cool.

I have some very fast delta fans loud as fuck 3 pin but they move 35cfm more then these fans move.

My 2 pieces are coming soon as they are marked shipped.

I will run 1 s-3 with the faster fans for 1 day then flip flop it to the other s-3.

See what happens.

BTW these are 4 pin plugs.

My deltas are 3 pin but I have a killer fan speed controller so it is not an issue.

I've already barked up that tree. Check back a few pages and you'll see my post about using server fans across the DC assemblies. Chips at 31 and DC cold to the touch did nothing for stability or hashrate. I am looking forward to finding out where the issue is...

Does anyone have an idea what can lead to this hashrate?

All chips seem to be fine. It is powered by a 1600W PSU (all 4 PCIe Cables connected), but it is only ~half of the promised hashrate.
Latest firmware is also installed...
Kind regards

Try a reboot.

That's an odd temperature difference between the two chains.

If you look at the HW (hardware errors) column, the number there is huge for the 2-day mining period. One of the chains (likely the low-temperature one) is having trouble. I have an S3 that behaves similarly and gets similar numbers; the hashrate is just slightly above 1/2 nominal (meaning 230-250).

If you reboot it, you may find that it hashes fine for a few minutes then one of the chains will start acting up again and your hashrate will drop. When this happens you'll see the HW number start going up. For my unit, I took off the case and removed the 2 externally-facing heatsinks to see if it was making good contact with the chips. It seemed fine, but I re-applied thermal compound and re-installed the heatsinks. This didn't make any difference.

What I ended up doing is UNDERCLOCKING the unit. Try 212, and lower if you have to. It can help if you power the unit down completely for a few minutes to let it cool down. I got my unit running at 395GH/s for about a day before HW errors started spiking again. I underclocked it further and it has been stable now for a few days.

YMMV.

Chain #1 is for sure not working.

Quick question for people who have made orders before from Bitmain. If Bitmain says shipping on Aug-7. Any chance they might send out the S3's that cost .64 btc while they take the rest of the B5 orders?

since there are so many miners here and I want to buy ANTMINER S3 I'll post my question here. Is there a chart of multipool mining profitability in fiat over a long period of time (6-12months)? If not maybe you can tell me from your experience..

I want to know whether the current $1.6/100GH/day is somewhat stable and can be expected to stay that way the coming 6 months.
(I'm a newbie regarding mining, so with this miner I can use it for multipools right? Grin

)

No, it won't. You can expect the income (in BTC) to drop 20-30% every 10 days or so. Go and read up on 'difficulty'

Whats this 20-30% witchcraft?

I see the last diff jumps were 3% and 8%, Here's hoping they stay around that rate!!

Bitcoin Difficulty: 18,736,441,558
Estimated Next Difficulty: 19,526,251,935 (+4.22%)

realistically i expect to see 9-12% for the next 2 jumps - difficulty is slowing but i think the last two weeks were a nice low hop from variance and the massive 20% jump before that. another jump under 9% would be amazing though, and almost surely lock in a profit for mining

I was actually asking about profitability from multipools mining other sha256 coins, and was hoping the average difficulty increase could be better than with bitcoin since there is always some new coin with high profitability. But I'm guessing people now mine those too just as often as bitcoin and the profitability would decline just the same..?

I use DHL exclusively because they're the best in my part of the world (Australia). Bear in mind people have different experience with different delivery companies depending on where they are.

what does your pool say you are mining at?

I have had bizzare reading in the gui that do not match my pool's numbers. In the end the pool pays you not the gui .

is cex.io reading 250gh?

Lol, they went from 0.64 to 0.66, don't they usually go down and not up ?

The price of Bitcoin went down in fiat terms.

At the end of the day, Bitmain is pricing the S3 in BTC based on the value of Bitcoin in fiat terms.
