What is wrong ? That ASIC was all good before tonight ... :-(

then after like 15 minutes ..

LOOP[0] OFF TO:0 (test serial failed)
0: disabled (serial problem)
1: disabled (serial problem)

same behaviour after 2-3 reboot (power off/on)

Looks like my RM1000 is not able to take the load anymore... which explain the loop 0 failed.

But still one ASIC is acting strangely ? Any idea ?

Allright ... so now I made a few tests with another power supply.

As soon as I put power in connector #4 ... 3 and 4 doesn't startup.

If I put power only in the connector 3 ... 3 is working.

Smells ... really bad

Smell scares me personally.   I can say I have had good luck with RM1000's on other miners but I have never used on SP20.

I would ask SP support if you can open it up to see if something is melting or what's causing the smell.  The reason I say ask them is I don't  want you to lose warranty from opening without their consent. (This could have changed but I'm like 75 percent sure opening on your own equals lost warranty, but I could be wrong)

There is no smell at all, I was just saying I have a bad feeling about this ...

Ahhh ok that is better then I thought then.   What PSU do you currently have on trying to power the SP20?

I normally use a Corsair RM 1000. I tried to slipt the load with an Corsair CX750. (RM on connector 1 and 2 + CX750 on the connector 3 and 4).

The PSU and the unit won't start if I plug a PCI-e in position 4.

So I'm pretty sure it's a physical problem on the blade ...

EDIT: I can see the PSU trying to start but it doesn't ...
EDIT2: As soon asI only plug 1-2-3, both setup works (Split PSU or just the RM 1000)
EDIT3: Anyway check the ASIC4 ... DC2DC chip is overheating for nothing and won't clock up either ... sucksssssssss

what speeds did you use with this one?  1300 or less ?    1400 or more.

I am doing a survey on dead or dyeing sp20's  .   I want to know   the death rate for :

under     1300
between 1300-1400
over       1400

please let me know.  thanks


Around 1550. so over 1400

1427  Bitcoin / Mining speculation / Re: Does anyone have any recommendations on mining hardware and a pool? on: March 25, 2015, 09:57:44 PM
I always have an eye on Kijiji in Canada and most of the time the price are way too high. Ebay is overpriced too ...

The marketplace in this forum has some people selling stuff from Canada. Getting the gear from the States is normally not cheap because of the shipping.

It's safe to say that you don't have any trust at the moment. So you might want to use an escrow (middleman) to make sure either you and the seller are not rip off. Then you'll boost your trust rating.

From there, getting the gear you want will be easier.

At this moment, Bitmaintech is probably you best choice to get something new but the price is not so good with the current low BTC price. ROI (time to get back your investment) will be long.

If you just want to play around and learn how to mine. Start with an S3. You can probably find one for 70-100$ us in forum.

Don't forget, some miner has the power supply build in and other doesn't. You need to buy one for the S3.

Once you get the gear, choosing a pool is easy. Some mine at small pool like Bitminter and other prefer huge pool like Antpool.  You can also "bet" your hasrate in solo mining (which I would not recommend)

Hope this help.

Today looks like another +10% day, most likely it will be +10 to +15% at the end of the cycle.



We are two days in the diff... things can change quickly. We have seen peak in hashrate before.

All of this happened before and will happen again ;-)

Nope, I'm pretty sure the sky is falling for real this time Smiley

I was looking at AntPool and they seem to be having another good day (well, good for them, not so much for other miners).

Keep the the law of average in mind my friend ^_^

Luck won't keep it up forever.

You don't need luck when you have a significant percentage of the total network hash power at your disposal.

i'm just saying that speculating on luck doesn't work on the long term.

Like if the network luck is high during the first 500 block it doesn't mean it'll be the same thing for the rest.

But yes, if someone was holding 50 Peta off for a month+, i guess so.

I find it funny how people compare the bitcoin forums to eBay when it comes to pricing miners.

People here are trying to help out the community and give the best prices when selling.

If that isn't what you're trying to do, then go sell your miners on eBay and don't post them here.

I recently sold 10 S3s for 40 dollars a piece+shipping. That is a good deal. 600 for an S5 is not a good deal.

just my thoughts.



/Highfive

Let's wait and see, if in two days we keep the Hashrate over 375Peta, we are in trouble otherwise, it's just a peak as the usual.

Will an EVGA SuperNova 1300 G2] PSU be sufficient to power two S5's? (link: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011&cm_re=evga_1300_g2-_-17-438-011-_-Product)

I have a brand new one, and space is a bit of an issue so I'd rather not buy a second power supply unless I really have to. Don't pan to overclock the s5's so only asking about it's standard power draw.

it's about 590 watt at the wall so 1180 watt. You are using like 91% of your PSU. It's fine

now we also add one function to let you to submit pool change request
you can find it by click miner configuration tag, just below miner monitor tag

Great Thanks !

Lee,

I was wondering how the offline hours are calculated.

One of my miner has been down for like 6 hours now and 2 hours are in the offline register. (Current Maintenance)

Also had a miner down for like 2 hours last week and was still showing Online in the monitoring UI but the "last update" information wasn't updated and the unit wasn't hashing  This has not been reported in the offline report.

Thanks you ! :-)



if the miner donot submit new data after 2 hours, we will mark it as offline so the offline hour will be a little delay, however, it is the same thing when it is online, so the accuracy of our record is 2 hours.

Understood, thanks

That's taken by SimplisticStu.

+1.51 to +1.75 perhaps?
