Why did they sell it at such a high price?

the simple answer.... because they can. The market will bare it.

At this point there are really only 2 options for home miners... Bitmain and SP and Bitmain is less than SP.

The Avalon 4.1s are nice for home miners as well. Just a bit more expensive, but extremely quiet for 1+ TH/s. I have a mixture of Bitmain S3s, S5s, and Avalon 4.1s.

I originally had 9 S3s at my office, but have since brought them home and replaced them with the Avalon 4.1s since they are much quieter and virtually have almost no sound at all since noise is the concern at the office.

Who's the North American supplier for Avalon 4.1?

Only place I know to order is ehash.com

You definitely want a sine wave inverter powering a computer power supply and if you shop around they're not that much more expensive than a modified (stepped) sine wave model. I see ones on eBay like a Cotek SK-1500 for under $200. Look for ones with built-in chargers as some are just inverters.

That said, it's a fairly common practice to run office or home computers on modified sine wave UPS units. As they typically last 15 minutes or so during a power outage, that may be an exception. I've seen modded UPS units with external batteries that will last for days under load so that might be an alternative.

No harm to trying one, if it makes your power supply buzz or overheat, that would be a no go. Undecided

How safe is or would it have any effect on the miner if I were to have the ATX PSU run off a modified wave inverter?
We have 2 -6 hour power outages in SA. Angry

I don't want to destroy the PSU or the miner in anyway.
I am getting mixed responses online about using modified wave inverters.

The following article seems explicit about the possible outcome in using a modified sine wave inverter on sensitive electronics. I hope it helps:

So, the wave inverter would be powered by 12VDC batteries? Why not power the S5 from the batteries? The S5 needs a common 12vdc bus I think they said. So, batteries to the 12V bus connector board and the power supplies charging the batteries.

Oh, you probably fire up a gas engine generator. You'd need quite a few 12vdc batteries to drive miners for 2-6 hours.

Be an interesting experiment - take a miner to a fully charged car battery and flip a series switch then watch how long it keeps hashing while taking stats on remaining voltage and hashrate until it dies.

How loud is this compared to S3?

Much louder compared to the S3.

If the S3 could be classified as a "comfortable" volume, then the S5 would be classified as "very loud" by comparison (off the top of my head, I think the S3's are ~55dBA, and the S5's are ~70dBA)

I think you meant S5's are 70000000000000000000000000000000000000 dba

So as tinypic.com.

Do anyone have an I/O board V1.4? I have two of them, v1.01 (from the left, with sticker on the beeper) and v1.4. v1.01 has 16pin connectors to connect hashing boards, v1.4 - 18 pin. How can I connect the cable which is also 16pin to not damage the hashing board?..

Where did u get them?

Have had two S5 running flawlessly for three weeks and today experienced an issue (batch four, OE file system, CGminer 4.9.0, 306.25 MHz clock). One of the two appeared to have frozen. Perhaps half a day elapsed while both controller and Hash appeared stuck. Discovered the problem by observing lower than expected Hash on Eligius and traced it back to the specific S5 by addressing it, whereupon it displayed the miner status page (without my logging in or selecting it), but was unresponsive to GUI selections. I shut down the PSU for sixty seconds, fired it up again, and back to normal. It now once again appears fine.

Noticed today my Westhash account was down ~2TH/s. Did a visual on the miners and all appeared fine. Tried addressing the two S5s and neither responded. Power cycled both, checked their status (as well as the S3s), and all was back to normal. The temps are 42/44, 46/46 and neither has been o/c'd (at least, not since Bitmain shipped them.) The power supplies are CX750M with all four PCI-E connectors populated, the file system is the Jan 7 version, CGminer is 4.9.0, and the clock is 306.25MHz.

PS. Took a look around and it appears Batch 4 is sold out and I see no mention yet of a Batch 5.

Just discovered another failure, just one of them this time -- was frozen displaying the miner status page. Just raised both clocks to 312.5MHz, can't imagine why that would make a difference, but trying it anyway.

I have a feeling that its to do with westhash and generally altcoin mining as a frozen controller isn't a typical error we see. What could be happening is that on coin / block / whatever change, its flooding the controller with inappropriately low difficulty shares which is causing it to lock up.

Yea. I can show you a pic but first tell me how to upload a pic. It's been a while and I can't seem to find a help file.

you need a photo service like photo bucket or image shack

upload your pic to imgur or other free service, then choose the size (large thumbnail is good)
copy and paste directly in the post the link from imgur that says message board formatted image or something like that.

Thanks... I'll try that!!!

* btcminer021 sits patiently waiting for S6

while others are happily hashing on the current equipment...

it is unlikely that S6 will be a huge revelation-most likely 0.4Gh/w or slightly below.
3.6Th at ~0.4Gh/w=1440w, at the limit of a typical 15w circuit at 115V.
I would be surprised if it will be something drastically more efficient.

Also, don't expect to pay less than $1500 shipped for it. It is NOT going to be a bargain because BMT large box machines never are.
