501  Bitcoin / Hardware / 2 S1 180 GH/s with 1 Corsair CX750M or 2 S1 OC 200 GH/s with 2 Corsair CX750M? on: June 02, 2014, 08:27:33 AM
Hi, what do you recommend me?

I want to buy another S1.

Right now, i have 1 S1 Overclocked to 200 GH/s, with Corsair CX750M.

If i buy another one, i cant use it in the same PSU, unless i dont OC them.

So whats better??

2 S1 @180 GH/s with 1 Corsair CX750M?
Or 2 S1 @200 GH/s with 1 Corsair CX750M each one?

Thanks

Buy or don't buy. It's plenty of people like me that's been mining through PB for a few months now.
Go on the site and see the payouts or just ask the members about their payouts. If you're scared don't
invest. All I can say as someone who's been a member of PB since March buy a small contract and test
it, if you don't trust it. Or just don't buy. Why would I care who or how they're mining when I'm getting
paid my payouts on time?

Hi guys i have a question. I have my s1 for rental, but i would like to know some things:

when a guy rents my s1, and he pays for example for 1 day 0.0135 BTC, i receive that money, ok, but how much BTC will he earn?. I mean, he is paying 0.0135 BTC (4.21 EUR) for 1 day, so "i suppose" he expects or he should earn more than that, right??.

thanks

I put my rigs on rent and also rental at times.
Sometimes its loss some time its gain(New coin release).
Ideally rental are just above the most profitable coin.
Some newbies do it to learn.
All depends on which coin is mining.

Ok thanks Wink

Let me ask you something guys.

Antminer S1 costs 178 EUR at bitmain.

Ok, u buy it and u mine every month, and lets say for example u earn ~120 EUR /month, ~1440 EUR /year and u have to pay also POWER.

On the other hand, u can buy 180 GH/s on pbmining(0.0053 right now BTC / GHs.... 180 GH/s would be 297 EUR),  so in 1 year u earn with 180 gh/s on pbmining ~1668 EUR because u dont have to pay power. u payed 297 EUR for those 180 GH/s yeah but u get ROI and more...

So... how can this be that easy?.

I mean... yeah, u earn maybe 20 eur less than with S1 / month, BUT u dont have to pay for power...... what am i missing here??.

Thanks!

Anyone? Huh

Im getting my first s1 this week.

Do you guys recommend OC S1 to 400 MHz / 205 GH/s??

Thats 360w without overclocking vs 500 - 525 w overclocked.

180 GH/s vs 205 GH/s.

Its worth it OC then?

thanks

Just a headsup, the CX500 on sale at newegg for $50 + $20 rebate.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027
I have 1 on an oc'd ant and it works great. If you can find a way to turn in multiple rebates, then you can get a bunch of these at $30 each. Would only cost $150 to power 1TH/s.

You can do that with 3 of these for slightly more, but you can power 6 ants and no mail in rebates
http://minersource.net/products/dell-750w-psu-slash-adapter

Whats the point buying piece of pcb which cost more than psu?
I dont get it, check this:

Cables costs: 2gbp
psu cost is :12gbp

You can plug up to 2 units on one PSU by them cables.

All my PSU have mods to slow the fan. As original one are sooo loud.

No issues what so ever.




Where can i buy then necessary cables for using dell with s1? . And u know how much kw/h consumes s1 with that dell psu? ?
512  Bitcoin / Hardware / Re: [Antminer S1 Sales open] Price changes daily, now 0.55 BTC for 180GH/s on: May 03, 2014, 01:10:24 PM
I will receive my s1 next week,   what altcoins you mine with s1? . And i want to buy a corsair cx750m is a good psu?  Thanks


You will spend to much money for PSU, just go for dell poweredge 2950 750w and it will cost you like $25 or 15gbp


Mmm but i read that corsair can run up to 2 s1s,  its not a better option than that Dell?  Just comparing prizes maybe yeah its cheaper but its a good psu? And can
run 2 s1s? And that dell psu comes with conectores for s1 or i need to buy cables?

516  Bitcoin / Mining support / Re: Power supply problem with my antminers U2+ and the usb hub?? on: April 16, 2014, 10:18:28 PM
Sorry I had forgot about that. I too am running off an RPi, and just a heads up: you're going to have a hard time finding a hub strong enough that isn't 3.0 to power all six. As a suggestion, get two hubs. I used this thread to help me out https://bitcointalk.org/index.php?topic=253749.0 great info on all the community top rated hubs

Ok thanks mate Wink
517  Bitcoin / Mining support / Re: Power supply problem with my antminers U2+ and the usb hub?? on: April 16, 2014, 08:11:22 AM
The Anker 10 port 3.0 hubs are supposed to be pretty good. 12V 5A

I cant use 3.0 usb with raspberry pi and my antminers u2+, just 2.0
518  Bitcoin / Mining support / Re: Power supply problem with my antminers U2+ and the usb hub?? on: April 16, 2014, 07:04:52 AM
An AntMiner U2 requires 2.95W at 2Gh/s, per the Bitmain website. That means that you must account for .6A or so for each miner, and leave a little extra to keep the hub from burning out prematurely. Six miners are drawing 3.6A, not to mention whatever the fan is using, clearly putting you above max. I saw your ebay post and assume you're not in the U.S., but for what it's worth I am running five of these AntMiners on a Rosewill 10 port hub as well, but the 5V 4A version. http://bitcoinrigs.org/wp-content/uploads/2013/10/rosewell-10-port-usb-port-2.jpg Got it on Amazon. I also don't suggest you buy another psu and try running your hub with it: if the two are not rated for each other, you're probably going to short out/probably destroy your equipment/probably get shocked/probably start a fire. Good luck man

Ok thanks so much. Now they are working perfect. I reduced the overclock to previous frequency, and now the 6 work without problem. The antminer will use an own psu(just bought it), but i would like to buy an usb hub with vertical align for the antminers, just like the one i have. Can you recommend me any that comes with a good psu? thanks
519  Bitcoin / Hardware / Re: Which USB hub to use with Block Erupters | NanoFury NF1 | BPMC Red Fury | Ant U1 on: April 15, 2014, 10:27:40 PM
Amazon has their own custom built 7 port usb 2.0 hubs with 5v/4a adapter for $19 shipped (prime). Ordered 7 for an antminer project, i'll report back how they work out.

http://www.amazon.com/gp/product/B00DQFGJR4/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

Actually they were $12 at some point ... I should've ordered more of them at that time. I've been using them for testing various quantities of NanoFury boards and so far they've been performing pretty well.

A follow-up :

I've been using those Amazon ones for testing of the dual-chip design and I am very impressed by them - I've plugged them into USB3 ports and 3 miners are happily hashing there when pushed to the limit.


And a very disappointing observations from this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817111981
(and there are a lot of similar ones with 2.5A power brick)
The power brick is a piece of junk and as soon as you add some load to the hub (let's say 1-1.5A) the voltage drops to 4.6-4.7V and if you push it even harder it goes even below 4V.
This was a nasty surprise for my desktop which in essence ended up having to provide all the power as that power brick's voltage was well below the PC's 5V.

Hi do you recommend me that  usb hub for mining with antminers u2+? or what usb hub can you guys recommend me? because antminers u2+ have heat sink and are harder to fit Wink thanks
520  Bitcoin / Mining support / Power supply problem with my antminers U2+ and the usb hub?? on: April 15, 2014, 08:35:52 PM
hi i have a problem.

I have this usb hub i bought on ebay with that power supply it came with:

http://www.ebay.es/itm/261433004354?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

the power supply says: INPUT 100-240 V - OUTPUT 5V == 3.5A

and i have a raspberry pi connected to that usb hub, as well as 6 antminers U2+ and a vent.

I have minepeon, and bfgminer.

The problem is, that i have the 6 antminers but seems like 2 of them have this problem:



and finally, 1 antminer disconnects and it says i just have 5, and then they all work fine:



my question is.... maybe this is because my power supply for the hub is not enough, and like i have a vent, 6 antminers u2+ and the raspberry pi connected to the usb hub, they dont have enough power and thats why 6 antminers cant mine together and just can work 5?? here is the usb hub with the antminers and the vent:



Also here you can see, even with the raspberry pi connected to my computer, and the usb hub just with the vent and the 6 antminers, that 1 antminer always accepts less than the others, and runs at a lower hash rate:



So if thats the problem... what power supply do you recommend me?? i saw this one:

http://www.ebay.es/itm/5V-8A-40W-LED-Power-Supply-Netzteil-230V-AC-fur-WS2801-WS2811-WS2812-B-Strip-/281268122538?pt=Netzger%C3%A4te&var=&hash=item417ce2f3aa

and if you can recommend me also another usb hub because i need to buy another one.

Thanks
