Willing to extend shipping to Canada? I'd prefer to buy from you than from the German guy with no ratings who uses a cropped picture right off of the x6500 website.

Sorry, I failed to mention... (although I am surprised the default assumption is that I am downloading source in linux and building it myself)
I am running the 2.11.0 win32 build of cgminer under Windows 8. This exact build does not have these issues on my windows 7 laptop. The only difference would be perhaps AMD drivers that are a few months older (due to HP being a sack of crap at releasing drivers. If I wasn't using hacked drivers, I would be saying my laptop is using 1.5 year old drivers, instead of just a few months.)
I have a 5770 installed on the same machine as the 6950 (unlocked) that also has the same issue. I tested them separately with --device.

I've recently started looking into litecoin mining. Setting it up on my 6770m was easy and it is hashing away at coinotron with notroll.in as backup. Worked fine so I set up my 6950 to do the same. So cgminer was reporting 444KH/s. I go to sleep and wake up to maybe 10 shares 10 hours later. I check the output and see no "accepted" just a continuous list of
stratum requested new work from pool 0... stratum requested new work from pool 0... etc
No rejected, no accepted in my tests. The pool reports a hashrate of 3.5KH/s reflected in shares. I've tried older cgminer versions between 2.6 and 2.9 and had the same issue or ran into separate, older issues. I've tried two pools: coinotron and notrollin.
Anyone know what could be going on here?
Summary of information requested or mentioned later in the thread: -running on windows 8, 64-bit -6950 unlocked -5770 running in same machine - same problem -laptop running 6770m, windows 7 x64, same cgminer version. slightly older driver, still 12.x catalyst - works fine. -desktop on 13.1 driver 9.14.10.0945

"The German guy selling x6500s on bitmit"
Worthwhile? Opinions?
Edit: sorry, wrong link. Got kind of confused when people where talking about the recent crash instead of the FPGA. Link fixed. Edit, edit: Can't fix link because Bitmit.net is down. Replaced it with a quote. He's got no rating and is using a picture straight off the x6500 website. But he is using escrow.
I'd prefer to buy from the USA based guy but he doesn't appear to be willing to ship to Canada.

For a large entity with the agenda of overpowering the network, without ASIC the system is a cheap combination bike lock. When all asics come on line the hashpower makes overpowering the chain much more challenging. This will be reflected in bitcoins worth. what is worth more? a 4 barrel combination bike lock or a bank vault? More hashpower means more security. worth of a storage facility is proportional to its security.
After the first genesis block was laid, when difficulty was 1, had you been privvy to the network you could have overpowered it with trivial computing power. Would you prefer it stay like that, just so you can mine easier?
I disagree. The only reason this has been true in the past is because a relatively large portion of people involved with Bitcoin at the moment are involved in mining or investments in mining. The average user of the future wouldn't know anything about the security of the Bitcoin network. How many people who do online banking know what https or a public and private keypair are? We are not talking about the worth of a storage facility when we are talking about Bitcoin as it becomes mainstream. We are talking about the worth of a currency.

Why do you support BFL at every single delay and let down?
Why do you care? How much are they paying you?
How much are their competitors paying you? (disclaimer: not a real accusation; just trying to make a point) How much are you invested in BFL?
How is that any of your business?

chips are now at packaing with as josh admited already run intro problems
Source? I seem to have missed this news and I've been keeping up to date with his posts and the "unofficial BFL news" twitter feed. indeed bfl nothing but lies 3 weeks delays for a 24 hours process like bunping
How do you know this? Someone I know who worked for an electronics company said it took between 6-10 weeks from the when the fab receives the ASIC design. He said the packaging process took between 1-2 weeks. This is for an established and experienced company in a good relationship with the fab. Admittedly though, he doesn't know much about the process but from where I stand right now, you've not mentioned your experience or research at all. He also did not mention bumping but I find it hard to believe this is a 24 hour process, especially when a fab has multiple customers. So please, enlighten me on the manufacturing processes and send me a link to the news item I missed.

I forgot to mention and was reminded when blockchain.info went down. In my case, I use a lot of data from them. I don't do scripting or if statements in my spreadsheets so if blockchain.info sends me their "we're down" page, it completely screws up my spreadsheet because for some reason, the import will go into multiple cells, overwriting your other data. (html tags all over the spreadsheet)
So essentially, when blockchain.info is down, my spreadsheet is down.
To fix this, once blockchain.info comes back online, simply roll back the spreadsheet changes to the last time they were correct. In other words, to before you tried to view your spreadsheet while blockchain.info was down.
This is a simple fix that can be done by clicking on the "all changes saved" or "there were saved changes" etc. That small underlined grey text that appears at the top. Then, in the sidebar, simply select the version before the screw-ups.

Why somebody will mine if the cost of electricity is bigger than profit from mining?
Why somebody will continue buying into a stock they think will go up in the long-term, even though they are throwing away their money in the short-term? Apparently some people who shut down a while back, turned their rigs back on recently when the price went up. Where would they be if they had never shut them off? It all depends on how much you believe in the value of the system. How much confidence you have in the value and how much risk you are willing to take. This varies between people. Mining for short-term profits by instantly selling is only one viewpoint. I'm kicking myself for sending BFL a significant amount of Bitcoins (significant by today's standards). In retrospect, paying in cash would have kept me with more Bitcoin value. That said, I was still hesitant on the system and wanted to keep all my financial risk inside the Bitcoin economy, separate from my "real" cash. Had Bitcoin somehow collapsed to under $5 by now, my losses would seem less than if I had paid in cash. And... if I had paid in cash instead of BTC and it collapsed, I would also be kicking myself.

This is an interesting challenge. Let's spread it around and see how long it takes. I spent about 10-20 minutes randomly guessing phrases and found only one address from a phrase I had come up with myself: "may the force be with you". It once contained a single satoshi probably a long time ago. I think your level of easy may boil down to if someone knows what kind of personality and person you are. If they don't know this, a dictionary attack might work faster since we know they are all lowercase English letters with spaces.
aside: @SIGNW - I don't think trolling means what you think it does.

http://www.youtube.com/watch?v=BHqgHFcmAOcI find ignorance funny to read. Funnier still, now that I know a lot about how Bitcoin works. So here is the goal of this thread: 1. Post an ignorant, funny or both comment that you have read (or multiple) inside the quote tags. Source them if you want, but this is not required 2. Outside the quote tags, discuss the hilarity of others' comments, the effects of the comments, or other interesting things regarding how Bitcoin is perceived. So I will go first. Posts should follow the following format: ::start "i didnt like BTC b/c i dont understand it. plus you can get them hacked."
"Have fun with your 101010010101101"
I found the second quote pretty funny for some reason. The first one is contradictory. He says he doesn't understand Bitcoin but he seems to think he knows enough to be able to think that "you can get them hacked." ::end So it doesn't have to be long or anything but I just think a topic like this could get some interesting discussion going.

[...]chips. [...]done he said except programming it.[...]bought all the parts/chips from China already. [...] just needs programming done. [...] into an electronics business and was able to get their hands on ASIC chips according to what he said because of those connections. He told me things about a J-tag USB identifier and all stuff that doesn't make sense to me. If you want to maybe help in this little project, let me know and I'll pass on his contact information to you. I think they have parts for about 20 units. That's all they wanted to build I guess.
Your friend is into electronics and doesn't know the difference between an ASIC and an FPGA. This is very obviously several FPGA chips he has. It sounds like he bought 20 FPGA chips and needs help programming them. He better hope they are Spartan-6 LX150 chips or he is going to be very disappointed with the hashrate. If they are, though, he should be able to achieve over 4GH/s. This means he better hurry to get them online before the hashrate jumps as larger companies roll out the ASICs they have been developing for months. Anyway, I personally can't help him but I'm sure many on the forum can. FPGA mining has been around for a while. For your friend's information, an ASIC is an application specific integrated circuit. It is build to do one thing. In other words, it is "programmed" in hardware and created already able to do what it needs to do. The advantages are low power and die size and they are often used in lower power applications or in markets where competition on power efficiency is important. FPGAs are designed to be flexible. They can't do anything. They need to be programmed in order to be able to execute the code given to them properly. This wastes space and makes them inefficient. Do not confuse general-purpose CPUs and GPUs as FPGAs. They are ASICs. They cannot be reprogrammed. This doesn't mean that they aren't designed to be able to do a broad amount of things. That is the extent of my own knowledge. If you are actually interested, consult wikipedia or ask someone else. Edit: @DeepCeleron: Don't be a smartass. Especially if you have nothing useful to add. I've edited this post to say this instead of posting new because I don't want to interrupt the now back on topic later posts.

bitcoinexchangerate.org/price is new to me and I like it. The importXML command I was also unaware of. I'll be adding those to my spreadsheet. I've been using a couple methods to get the price myself. 1. The first thing I used was =ImportData(" http://blockchain.info/q/24hrprice") to get a 24-hour average price. The webpage is just the price text. But I found at least once a week, the price would be totally messed. Once it was $14 when Bitcoin had been $20-$30 in the past week. 2. I found this command that I can't quite figure out: =Index(ImportHTML(" http://bitcoincharts.com/"&"?workaround="&INT(NOW()*1E3)&REPT(GoogleFinance("GOOG");0),"table",4),2,2) But he seems to be importing the latest price from bitcoincharts and somehow forcing it to update faster than the standard ~1 hour updates of docs. 3. I wanted the latest mtgox price from mtgox so I whipped up a quick bash script on my centos webserver: stop=$(<stop.txt) while [ "$stop" = 0 ]; do stop=$(<stop.txt) wget -q https://mtgox.com/code/data/ticker.php cat ticker.php | cut -d',' -f8 | cut -d':' -f2 > last.htm cat ticker.php | cut -d',' -f5 | cut -d':' -f2 > vol.htm cat ticker.php | cut -d',' -f3 | cut -d':' -f2 > avg.htm cat ticker.php | cut -d',' -f2 | cut -d':' -f2 > low.htm cat ticker.php | cut -d',' -f1 | cut -d':' -f3 > high.htm date > lastupdated.htm rm -rf ticker.php sleep 5 done then I just ran it: ./update.sh& disown [job#] Then I just point docs to the webpage with =ImportData(" http://mysite.com/last.htm") I know I could have done parsing in some other web language or something and made a script there but I'm way more familiar with bash shell scripting so this was much quicker for me. The wallet contents are easy to fetch from blockexplorer.com/q/ I make a chart like this: A | B wallet address | =ImportData(" http://blockexplorer.com/q/addressbalance/"&A1) ...[for however many addresses are in your wallet] total | =sum(B2:B12) I created a public spreadsheet that I planned to put all kinds of data in but there was no interest so I abandoned it and just keep updating my personal one.

Alright, where the never 40 thread at?
|
|
|
I just had this on my favourites to check once in a while along with the BFL site and the unofficial news twitter feed. Just wanted to confirm the OP has abandoned this thread before I remove it. There have been quite a few updates from BFL since. And there are still questions about Avalon's shipping schedule.

That's the contact information for the hosting company, except for the email there.

So is this thread dead and will no longer be updated?
