The shipping of B5 started, 7 days earlier than promised date. We added more B5 units for sale.
Excellent - I'm just waiting for my wallet to synchronize...

Quick question relating to PSU...

Will I be able to get all 4 plugged in to OC the S3 using this? (I am nooby at this stuff, thx for help)


Corsair CX Series 600 Watt ATX/EPS Modular 80 PLUS Bronze ATX12V/EPS12V 552 Power Supply CX600M

Any help would be great. I ordered those. Just want to make sure it will work with OverClocking while I have a chance to change order.

Got my 2 S3's (Batch 3) up and running and they are giving me a solid 440Gh each.

At stock frequencies with 1 power plug to each blade, I am seeing 14A+/- through the power connector. I am powering 2 units with 1 Bronze 850W Antec PS, and it is using 730W at the wall.

I will play with overclocking and post those results later.

Yes "warranty' have not much value in the mining hardware.
41 - 42 was my temperature peaks at stock clocks.
I don't have any link to the thermal grease for now.
I'm searching for it to buy the same brand or the alternative one having >3 conductivity.
But most of the products I'm seeing is of conductivity 1.
I will post here the link if I find it or some else who has experience in doing this will support here.
Interesting my miners are all running in the same temperature range like yours and I have similar performance to yours maybe this will help me too.
Still though our temps are half of the max 80C but I guess its averaging the temp so maybe some things are hotter than others....

My miners run at those temperatures as well, if not more, and I haven't been having low hashrate issues. In fact they both are performing at low 500s. I don't think the temperature is a symptom at all.

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

Hi,
Please PM us your order ID and email box, and we will guide you to test hash boards separately, to find out the issue was caused by control card or hash board.
Then to the next step of RMA flow.
Our apologies for the inconvenience, we will try our best to reply emails and offer tech support ASAP.

I put a ticket with bitmaintech support and I wish to share it with you all.
My S3 was hashing low at 400 - 420. Long term average was 421.
Bitmaintech engineer told me to remove the heat sink, clean it with a cloth and apply thermal new paste.
They recommended to buy "Dow Coining thermal paste grease" for this purpose.
Which can be sourced from ebay or amazon.
If its not available at your location buy any good thermal grease which has conductivity above 3.
Also I asked then about warranty issues if that type of a hack ws done, and they assured me that no warranty will be void for doing it.

What is the temperature of your miner?
Also do you have the links to the thermal paste ?

Thanks, good to know about the warranty, but I hope I never have to use it  Smiley

Have you tried a lower diff? you seem to be discarding most of your work due to a high diff selected at ghash.io.
Ok I looked at all of my units 7 in all and the HW errors and utility are the big differences, yours show huge HW errors compared to mine in 5 days show <300 vs your >4700 in half the time and my utility is 23 verses your 13.
So you should open a case with Bitmain as something is very wrong.
Does your power supply use a single 12v rail ?

open up ur S3 and re-apply the thermal paste
i think it'll be leaking around the components
well, maybe bitmain was in hurry and just shot the thermal like making cake  Cheesy

check the 1st blade, no need to open the 2nd blade

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)

I'd take some serious time learning more about bitcoin before you invest a cent. The difficulty changes after every 2016 blocks.  Here is a list of the historical increases.

https://bitcoinwisdom.com/bitcoin/difficulty

In the last 6 months it has gone from ~3 million to ~19 million. SO NO WAY you will be making anything close to $1.6/100GH/day in 6 months.

thanks! I know about bitcoin difficulty and got burned already Grin
I'm asking about the other coins since multipools mine the most profitable, which ever coin it happens to be. But there is no "profitability" chart of multipools over such a period of time.

clock

 www.nicehash.com

you can study them and may be able to figure out if they are better for you then straight btc.

Nicehash was very profitable earlier, now it is also settling down as more people entering into the pool.
If newer coins are launched hutting at nicehash will give a killing profit as before.
A consistent supply of new sha256 alt coins or a lot of other active altcoins are required to mine on a profitable multipool.
But these was one SHA256 coin a couple of days ago, which was a way more profitable than BTC.
I don't wish to name it here. It was some W***coin. Inshort, practically, BTC is the most profitable at this time.

I have been mining at multipool.us for several months. I haven't kept detailed records but can tell you that it now spends >95% of the time mining bitcoin directly, not any of the other coins. The way the pool works ensures that any of the more profitable coins will be mined until they are approximately the same profitability as bitcoin, so it effectively destroys its own market. I imagine the other multipools will have roughly the same effect.

The only way to beat the multipools is to mine newer coins before they get added to the pools, which is a bit of a gamble and isn't a set-and-forget option which I think is what you are looking for.

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.
I'm not sure I would call that HW error number huge... it's 0.034%.  It's certainly larger than what I experience on my S3s, which give me about 0.0017%.  The WU number is very telling, though.  You're getting 3525 and you should be somewhere between 6100 and 6200 at stock clocks.  Also, the extremely low temperature of chain one is an indication that something funky is happening there.  If you reboot it from the web console, does it come right back up and show all ASICs as "o" status on both chains?  If yes, then there's a power problem and the ASICs on that first chain aren't getting fed enough to hash at the specified clock rate.  Another question: if you power down the unit completely for about 5 minutes, then start it back up again, does it report proper hash rates, but then drops over time?  This would also point to a problem most likely in the DC/DC component.  What happens if you try to clock it lower (like 212.5 or even 200)?

Finally, I'd open a support ticket with Bitmain.
