Nice to see that video, thanks. Man, the package looked like it had been drop kicked all the way from China. Glad they seem to be taking internal packaging to heart.

Enjoy yo hashing powah.

Image does not work for me either.

image url seems to be some ridiculous long googlegroups URL. I'm guessing that those who are not part of whatever that is cannot see it.

EDIT: If I open the URL on its own, it sends me to a page that lets me download the image. Perhaps post it up on an image hosting site for direct linking.
123  Bitcoin / Mining / Re: Miner Variance on: May 19, 2013, 04:58:53 AM
On a practical level, reported hash rate is inconsequential. Every pool system relies on shares submitted to calculate rewards. Hashrate is simply a human vanity.

Except pool reported hash rate is determined by submitted shares. The idea is to try to proactively determine a failing miner before it goes to zero.

If you are able to determine the expected variance of a miner then anything outside that variance is cause for concern.

Again, on a practical level, if you are simply worried about a failing miner, then you could simply look at time since last share submitted. Estimated hashrate being more or less worthless. Your actual hashrate is zero when a miner fails, regarldess of what is being reported. Unless you mean something strange by "failing miner", as in it is stuttering or something, I don't know.

We startet in Mar before the asics appeared with 30 TH/s and now we have 90 TH/s

CompanyPcsHashrate GH/sTotal
Avalon30070 GH/s21,000 GH/s
ASICMINER Sold25010 GH/s2,500 GH/s
ASICMINER selfmining200010 GH/s20,000 GH/s

Makes a total of  43.50 TH/s

30 TH/s + 43 TH/s = 73 TH/s

Where did the others 20 TH/s did come from? from GPU and FPGA miners because the price pushed profitability?

Anyone have an idea?


Only one response about price? C'mon.

Price. Price. Price.

Bitcoins are worth more now than they ever have been, with the exception of the crazy ass bubble high when they were worth 2x what they are now. Even after the "crash" they're still worth about 5x what they were in February, and 10x what they were in January.

The fact that with the addition of ASICs, the current difficulty is *only* 3x higher is actually a testament to the conservative nature of miners (if I lived just about ANYWHERE else I'd be sitting on a big fat mining farm as we speak).

A shorter response might be, "yes, GPUs (and a few fpgas)."

127  Bitcoin / Mining speculation / Re: New ASIC project was announced in Chinese forum, 200T in Sept. on: May 17, 2013, 07:28:23 AM
On that list why is ASICMiner orange, putting it on the same level as BTCGarden, which has nothing that I see to back it up (no website, no pictures, no concrete plans), while BFLabs is Green, along with Avalon, having delivered nothing more than like 5 or 10 jalapenos?

ASICMiner has been hashing away with 20+TH for months, they've delivered every product that they put up for sale, have pictures of working product. Seems a little bizarre.
128  Bitcoin / Mining / Re: What does everyone think of these miner rental sites? on: May 17, 2013, 07:20:11 AM
btccheap is a clone of mininunited (probably run by the same person) which has now conveniently "closed" because its "now illegal in the US" (which it isn't).

Clear scam, plain and simple. Wish there was more legal recourse against these people.
129  Bitcoin / Mining / Re: Is my Kill a Watt wrong? says pulling almost 1300W from 1200 W PSU? on: May 14, 2013, 11:50:54 PM
Yep that's normal.

1,200W is the amount of wattage the PSU can supply to the computer.

An 80Plus Gold PSU will be ~87% efficient at 100% load, according to the specification.

This means that for ever 1 watt you pull from the wall (which is what your Kill-A-watt is measuring), you will supply 0.87W to the computer.

A 1200W PSU supplying 1,200W to the computer will pull ~1,380W (1200/0.87) from the wall.

If you're drawing 1,300W, your 5 card rig is really only drawing 1,131W (1300*0.87).


no i am running a 5 card rig but I have only 3 cards running off of this PSU.


The other two cards are ru nning off of a different PSU.


I have read what others are drawing running 7950s and this seems very very high.  i have read a few people running 3 cards off of 800W PSUs.   these 7950s should only draw about 200W percard when mining right?

You probably screwed up the connection in bridging the PSUs. Since your single PSU can handle it, why not go buy some SATA/molex adapters and just run everything off the silverstone?

Great auction for the seller, for the buyer, not so much.

Well I guess put me down for 1 in case 150 people don't pay up Tongue

Also forgot to add that PayPal screwed me on US to CAN conversion.

Yeah they'll do that.

I guess I can partly see Paypal's side from the pre-order nonsense, but if you're selling a physical existing object, which for all intents and purposes is just a computer, I'm not sure how you can deem that specific item (which is legal) as against TOS.

HVAC is complicated, there's a reason why companies specialize in providing this service. If you don't mind wiring a bit you might consider hooking a high CFM shuttered fan to a thermostat, install it in a window and block off the excess space. Then pull in cool air from the house, circulate it in the room and set it to vent only above a certain temp. Downside is that unless insulated well you might pour warm air into the house causing the AC to run more, otherwise you are venting your AC air however. Neither is ideal.

Possibly the best would be hook up a swamp cooler to a window, blow cooler air over your rigs, then vent out opposite window. Not too expensive, electrically not too bad, keep the rest of the house separate. Only downside is if you are in a humid climate it won't work and can make excess moisture an electrical worry.

Honestly unless you live somewhere ridiculous, just cross venting with high CFM fans is the best.

GUIMiner doesn't give you the tools necessary to make any kind of diagnostic. As mentioned, give cgminer a whirl, you might be getting HW errors, which I assume is the case, as 590KH/sec is pretty high for a 7950.
139  Bitcoin / Mining / Re: ASICMINER: 200 TH/s has been ordered for 2-3mo deployment timeframe. on: May 09, 2013, 04:48:41 AM
If a group 51%'d the network, no one would really notice or care (assuming no malicious activity). The price wouldn't fall to its doom, and bitcoin wouldn't just close up shop. If it continued that way for months and months, maybe then people would lose some confidence, but it's not as alarming to the "other side" as most of us would believe.

The network has actually seen a couple of 51% moments in its history, and despite the panic on forums by a vocal minority, it had very little effect on price.

So, assuming that Avalon really will ship sooner or later, and BFL ever makes a product, regardless of what AM does or doesn't do, the problem will sort itself out.
140  Alternate cryptocurrencies / Altcoin Discussion / Re: Should LTC miners ban use of ASICs? on: May 09, 2013, 04:44:17 AM
LTC is naturally ASIC resistant by the nature of the protocol. As are all the scrypt based spinoffs.

As for banning computing from an algorithmic system, good luck to that.
