Looks like old firmware

What is the last firmware ?? Does it help on perf??

Yes, reduced cpu load to 20%, fresh cgminer 4.9.0 and nice graphs Cheesy

Where did you get it? How does one install it? No idea how to update firmware. also, is it third party? Last thing I want to do is brick it.

If you need help, just PM me and I'll walk you through it if you want.

Of the 6 I just ordered one is running noticeably hotter than the rest. I think I know what I'm doing next weekend.

Temperature difference between the 2 hashing PCB was reported to the engineers and it was reviewed. So far, it is not the hardware caused issues, but rather where and how the miners are being deployed and managed per the engineers.

The temperature sensors are also rather crude, and on a large scale there will be plenty of 'miscalibrated' ones. I'd be more suspicious of the sensor reading incorrectly than one board running significantly hotter.

It'll be interesting to see what the temps are after I redo the thermal paste this weekend.

Thinking of two S5, outside of footprint, is there a real compatibility advantage to buying one EVGA Supernova 1300 Gold Vs two Corsair CX750M Bronze? I understand the CX750M measures as an 825W supply (per Dogie), so it seems to me the reason to choose the 1300 is less space and fewer power cords. Right or wrong?

[For reference, almost all of the Corsair PSUs have an additional 10% 'peak' rating and so have additional capacity.]

On my question - why i recieved secondhand shit different revisions? Bitmain answer - miner work well? If yes - go to ass hole!

if you were rude to them why would they be nice to you??

also, does it work?? even if it had some dust on it, doesnt mean it was sold to someone and returned.. it could have been sitting around the warehouse or one of their control test models. (which would probably still qualify as new if it passed their tests)

I'm not rude! I asked a normal question. In response, I hear - rejoice that works. I know how to distinguish brand new from used. I am more than 20 years doing repairs at the component level microelectronics.
I have always been loyal to bitmain. Even the theme started with the history and support on our forum. But after such a deception, their reputation will suffer. I promise!

Business have to be nice to customers, that's how it works if they want more customers.

Electronics do not get dusty internals from sitting around a warehouse, and no test procedure should run long enough to get the device dusty. A dusty device = a used device, plain and simple.

Anyone willing to sell its C1?
I can pay around 100$ for it (without hoping to roi neverthless).

Best regards,
ilpirata79

This is a thread for the S5, not C1, but regardless C1s resell for like $500, I don't think you'll find one for $100.

May the source be with you.

Why ibm does not sell servers covered in dust? Servers need qc too. So ibm can't and bitmain can? This is not right i think Undecided

Is it possible to power up and use one of the two hashing boards on the S5? I currently only have 2 PCI-e connectors on my PSU and wonder if I can use my s5 on "half rate" while I wait for my DPS-8000GB adapter boards to arrive.

yes possible. just remove the data cable from the board that you do not want to use.

so far all my S5 run about the same as this one so im very happy with all mine .

Next difficulty retarget occurs at block 350783.0 (eta 5.3 days): 50426253807.9 / +7.9% [est.] that still not to bad id be worried it went to 56 or higher .

Overall you'll have less loss using a single, larger PSU versus two individual ones. Granted, its not much loss, but hey, electricity is electricity.

The CX750M is bronze rated, which means that using a pair of them vs a single 1300W GOLD is about 2-4% more electricity usage. its not a whole lot, but its still $2-3/month savings with a more efficient PSU. over the span of a year, you'll have saved about $30 by using a gold-rated PSu over a bronze-rated one.

I have a 1200W Corsair PSU... how much can I safely overclock my C1 miner?

Thanks,
ilpirata79

The PSU is able to provide 1200watts, the C1 is drawing ~900 watts.
You can safely OC the C1 till max frequency, the PSU will survive only the C1 can get a bit stressed Wink

Cheeers

Sorry to bother you with this request... what are the suggested voltages for the different frequencies?

Thanks,

All of my miners are in a datacenter with 21c input temps, of the 6 miners all boards are running between 45 - 51 except for the one board that runs 10c hotter than all the others.

I'm going to pull the system apart this weekend and check the thermal compound.

has anyone ran any tests on wattage vs speed?

after the diff increase i am thinking about turning my s5 down to 300..
hopefully it will run cooler, the fan wont be so loud and it might use a little less watts..
