Doesnt bitmain usually lower the price of thier units to make it worth our while?
I wanted to buy another 10 units but at .58 btc it seems to be a losing proposition especially when you add in the electric cost.

Basic question about their shipping policies:

What if I say pay on September 21? Or September 21? When will I get my miner? Do they ship continuously or in some batches, once in a month, once in a quarter, once in a blue moon?

Their Google Translator powered customer service could be better.

Depends. If Batch 8 sells out, you'll get Batch 9 and who knows when that will ship. If it's in stock they'll ship right away. The new batch timing depends on their production. It's a gamble.

In the end they still need to make money. Any smart business sets their pricing to maximize profit as they see fit. Sell fewer units at higher profit or sell more units for less profit. There is a sweet spot. If you don't like the price, don't buy.

I am going to make so much money from these new s3+'s, then even more from the L1's. The L1's will pay for themselves in one month. GO BITMAIN GO

[allcoinminer]

if you wan to oc then one per s3 like rm650 gold.  or u can run 3 s3 on 2 rm650 normal speed

That's helpful if I have 3 miners. But if I have 2 miners; should I run them from 1 or 2 PSUs?

And how about the Gigahash question?

"Antminer's Google Translator supported customer service says if I use 1 big PSU to power 2 miners, they will generate only 800Gh/s. Compare that to 453Gh/s per single miner."

The main question!

Thanks!

That's not true. If the power supply has the capacity to deliver power for 2 S3,
then it will hash at the same rate as it will be in a single PSU.
But should make sure that you have enough +12V rail capacity.
A +12V  Rails having 35A capacity can run an S3 safely and a +12V with 70A can run two S3 at the same hash rate as the earlier.

my psu wont turn up.. i bought a brand new Rm 850 Corsair, using a paper clip with doogies diagram (green and black) and psu will not turn on.. any ideas or help boys?

using the paper clip i get a sound eachtime i power it up but the fans wont go on...im connecting the 24 pin to the power supply and other side has the paper clip on third and fourth pin as dogie's post, and then i connect 2 6pin pci -e to the antminer (not the same row ) and my power supply fan wont go on, just do a sound each time i turn it on or off.

Always keep a PSU tester handy. I use mine all the time. Something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16899261023

Hi,  my problematic s3 started to show X's on the UI.  it's at 218.75 frequency, but only hashes at 300gh/s.  i was told by Bitmain to clean pcb and reapply thermal--which i did, but this did not seem to help.  bad chips ?  anyhow i am waiting on Bitmain once again.  this s3 was out of commission for nearly a month with a bad control card, now it's missing over 140 gh/s.  i got a real lemon from Bitmain.

This is a very strange problem ,  I don't think is a bad chips.... but i'm not sure . Maybe one of the old user here can reply correctly to your question .

no they wont if knc ship there titans...

Unlikely, December is a LONG way ahead.

IF is true, but the cost?

I fear both won't ROI the way things are going.

Hey guys I need some help just got a S3 and connected it to my PSU heard the fans turn on.

Connected the Ethernet to my cable modem and when I try to go to 192.168.1.99 it doesn't load

Just be sure you don't shake stuff in the sink right below them.  A couple drops getting sucked into those fans and poof...no more Cheer (pun intended).

Try plugging the miner directly up to a laptop or PC like you would if configuring a router.  Once you're in there then you can set a manual IP or have the modem DHCP assign one.

To be fair, LTC difficulty has stalled for the last month, while previously it was rising 30-50% each month. Even the exchange rate has recovered from its low point. Doesn't mean it will last until December, but Titan buyers are now probably feeling slightly better than a month ago.

Yeah, the sink isn't used...so we should be good to go. Needed a fresh outlet and an exhaust window for some more S3s so figured the laundry room would fit the bill.

You need to set a 192.168.1.x subnet address on your PC, e.g. 192.168.1.10, netmask 255.255.255.0.

What are recommended PSUs for Antminer S3 to buy - in Europe/US?

I don't know much about PSUs, so a link to a PSU 101 article (at least as it relates to bitcoin mining) would be welcome as well.

I read:
http://www.reddit.com/r/BitcoinMining/comments/24intr/best_corsair_psu_for_my_antminer_s1/ch7mntp

"Efficiency ratings describe the amount of electricity that the PSU loses as heat while powering the unit. Because miners are always on and consume a lot of power, more efficient units generally recover their higher purchase cost in less than a year. In nearly 100% of cases you'll save money by buying a platinum (or gold) rated PSU."

Sorry for quoting myself, but any help with this? From a total beginner level, like understanding power draw on the PSU. Thank you.

Something to remember, when you select a power supply(s) keep in mind that even if you select the best 80 Plus Platinum supply, you'll want to get one rated at about twice (optimum/peak efficiency of most power supplies is around 50-60% of rated power) of what you'll be pulling through it.  So if you have 2 S3's and they're overclocked and pulling 374w each, then that's about 750w, so you should be looking for something in the range of 1200-1500w in platinum or gold rated. (also keep in mind that some power supplies have multiple +12v rails that usually max. out at 30A each, which might not be enough for a overclocked S3, so a single +12v rail might be a better choice)
Also, if you want optimum efficiency, use a 240v source if available (some houses have a 220-240v line for washing/dryer, be sure to switch the selector on the power supply to the correct voltage before you plug it in) which should add about 2% addition efficiency.

Sorry to say this but you have absolutely no idea what you're talking about.

There is some inefficiency to account for in most PSUs but certainly not close to 50% on current PSUs. Most PSUs will happily run 24/7 at 80% (or more) of their rated watts. Some good quality PSUs will run 100%+.

Poor example: Bitmain used cheap 1000w Gold Enermax PSUs in their S2s. And those miners use 1000w pretty consistently. Mine pooped-out after two or three weeks but many others are still using them many months later.

I love the response, I have no idea what I'm talking about and then.... "There is some inefficiency to account for in most PSUs but certainly not close to 50% on current PSUs. Most PSUs will happily run 24/7 at 80% (or more) of their rated watts. Some good quality PSUs will run 100%+."  If you read any decent power supply review that includes the efficiency curve, you'd know I was talking about the peak efficiency.  Please read up before slamming someone, your response shows you don't know what I was referring to, people that don't know what you're talking about might take your response as educated and I feel sorry for those that might take your word on something you don't know about.  Here's a simple power supply review that shows the peak efficiency is at about 50% (this random review I picked shows 89% efficiency at 600w and 85% efficiency at 1188w, meaning it's losing an additional 4% as heat at the peak power), there are many reviews out there that show that.  http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=222

Is there any tutorial for how to set a subnet address? Sorry if it sounds like I'm a newbie lol.

Ever heard of a modular PSU?

No, sorry, that's unfair. Good use of space. I would be a shame if Bitmain went all into clouds and stopped making miners like this.
