if that's the case, will some people who ordered actually not be able to get the boards?? You'd think that they'd be more careful about that

Hi, any updates here? I am really wanting to get a K16, and preferably be able to pay for everything in USD via paypal since it can be difficult for me to get enough bitcoin. Last time I used Localbitcoins to buy some, the price dropped so much overnight, that I didn't have enough to buy what I wanted anymore So I prefer Paypal for things like this, the fact that I can get credit card points, or have some assurance if the item doesn't ship, etc.

Anyway I'm also interested in what group buys people are using or if sensei could possibly provide the chips himself? I'd pay a premium just to get around the hassle of having to join a group buy, send in the chips, and also ordering the K16 here. Perhaps sensei himself could start a group buy?

I'm disappointed that I missed the window to order...I emailed them to ask if perhaps since the Paypal fiasco would cause some orders to be canceled, if I could squeeze in an extra order. No go I'm not sure why, there's already a queue of people waiting to get in on canceled orders. Presumably they have some units left over if people are canceling/getting refunds.

I emailed support and not only did I get a gift card 5 minutes later but support helped me find out that there was a bug with long decimal points in the BTC...Very happy with this service, will return again

This is really frustrating. It is a cool idea that I was excited about but I can't order, it keeps saying that price is fluctuating too much..Well..it ALWAYS will fluctuate so I don't know when I should order. 

Edit: Well, trying for about 10 mins now when the price has been at 12.19 for a while...price is still "fluctuating". Please someone tell me how to use this service!

Most certainly not. I don't think this has to do with how fast the card is running, since it only happens when I force kill the application. It's not like when I underclock the card and force quit it works.

I'd like to request to be whitelisted. I am just starting out with mining, but I'm currently writing some automation software to help restarting your miner after a hardware failure. I've been a member for over 2 weeks and my posts are on topic and hopefully insightful.

I just took this to be a fact of life for a while, but now that I am trying to automate restarting the polcbm process it's becoming really annoying. If I X out of the cmd window or do a taskkill to the exe, everything goes black for a few seconds and I get a "The display driver has stopped working and has recovered " message. I'm on an NVIDIA card on Windows 7 Ultimate and have the latest drivers. When this happens my fan control gets reset and I have to set it again, not to mention that it's annoying when it blacks out like that. In fact sometimes it even has rebooted after the black screen so I'd really like this not to happen. To get around it, I sent a keyboard interrupt (Ctrl C) in the cmd window a couple of times and it would exit ok.

Does everyone have this problem? Is there some sort of other way I can kill the process without killing the display adapter every time?

Thanks for the advice. I am using Cygwin in windows and I would rather use those utilities than Autoit, or make a python script etc so it is cross platform.

I would probably have to grep the stdout for the "hardware failed" message because I haven't been able to pinpoint a temp at which it gets unstable - it just shuts down after X hours..

Right now I am trying the easier route and underclocking my card slightly. Temp seems stable at 52.

I'm using a mix of Phoenix/polcbm-mod on my machines, but unfortunately my main rig is having hardware issues and will error out after several hours. I tried resetting my bios to factory settings (no overclocking) and maxing out my fan speed. That seemed to help a little, but still after maybe 5 hours it will inevitably decrease by a factor of 10 (!). Obviously I don't want to keep it mining at that rate, and there don't seem to be any ill effects when I restart it. The only thing I haven't tried is underclocking the GPU, which I'd rather not do since it should be running fine at stock settings. My case has very good airflow, so I don't know what's going on. Anyway this is a separate issue so...

I'm this close to creating a python/ruby wrapper just for this machine that will kill/autorestart when this happens, but it would be nice to have some built in support (warnings, stderr) if we get a hardware failure or our Mh/s is very low. Is there any tool that does this?

If I have to write one myself, I'll release it to the forum in hopes it will help other people with hardware woes.

Can you be more clear? I am not doing solo mining, I am doing pooled mining, so when you say you'll never find one but I may get lucky and find one I don't understand. I already have a small amount from Slush's pool. Could someone describe more clearly the pros and cons of smaller pools vs larger?

Also please don't tell me I'm wasting electricity, I don't pay it at my rental so if I even get 1 dollar I am making a profit.

I don't pay electricity at my rental

Thanks very much, I thought this may be the issue.

Is there anything to protect against this, or is it just the nature of slower hashing? A lot of sites always say, if you see issues with stale shares, check your miner. As far as I know Phoenix and polcbm mod have long polling built in.

In addition, I had some extremely slow machines on Slush's pool and I at least was getting some shares. The problem seems blown out of proportion on bitcoins.lc, is this because it's a lower hash rate pool?

I've got a lot of machines I don't really use all the time so I decided to set them mining. They mine from about 1-5 Mhs/s each.

I recently switched to Bitcoins.cl to try it out, as I was having issues with Slush's pool not giving me good payouts given my hashrate. Bitcoins.cl does show avg. hashrate which is helpful (although it was taken down for tuning I guess recently).

Anyway I don't know if this is an issue because I switched pools but is it just a fact of life that slow miners will get stale shares a lot of the time?

Edit: Forgot to add that I'm using Phoenix or polcbm mod for all of the machines, which SHOULD support long polling, so in theory I wouldn't get this problem as much.

Bitcoins.lc is reporting that I should get 0.07 per day! We'll see if it makes good on its promise

This is confusing stuff for a newbie Seems like Slush/Deepbit were the way to go, but then I saw all these posts to *not* use Deepbit. I have an account and I tried it for a while and I think I saw more reasonable numbers. I am giving bitcoins.cl a try now because it is free and I like the user interface. Is it better to go with bigger pools because there is  a better chance of coins being found, or smaller pools because the payout may be higher?Or does it turn out to be kind of the same?

This says I should be getting around 1.1 BTC per day Thanks I have not seen that site. I may try another pool to see if that's where the issue is, thanks.

I don't actually pay electricity at my rental so I figured I'd try putting all of my computers into Slush's pool. Only one of them has a decent hash rate, at ~50,000kh/s . The rest are contributing maybe an extra 10,000kh/s.

My max reward on Slush's pool was about 0.05 for a day, but due to issues with my main rig dropping hash rate, now I'm only getting around 0.01.

I'm trying to figure out if my rig going down to 3000kh/s is the real cause of this.  On June 6th and 7th I got ~0.05 and I must have still been having the same setup, if not worse. It's hard to explain how this is happening! On June 5th I started in the evening and got close to what I have gotten for a whole day the past few days.

Would you suggest switching to another pool? It's hard to see what my average is or if I was just lucky for  few days.

I've turned off Intel Speed step to see if that makes any difference (I don't think it would but I can try).

If the card drops back to 2d, what happens if I run a 3d game or something? Surely it turns itself back on?

Please someone help, this problem is driving me crazy. I only have one computer that is worth mining on, and I'm having stability issues. I was overclocking my CPU a bit, and I thought it was due to this. I analyzed the log and whenever I had hardware failures it would drop, so I reset to factory defaults.

Now using both poclbm and polcbm-mod even with default settings on my machine, I drop from 50ms/s to 4mhs/s. There are no errors in the log.

Does anyone have any idea what could be going on? The computer is literally running idle for hours and I come back ant it is stuck at 4mh/s. I haven't been watching in enough to know if it drops suddenly or gradually down to 4.

This is an NVIDIA card and it is running the latest drivers. My internal temps only ever go up to 56C max, which is not that hot for this machine.

At the very least, is there some sort of flag or utility that will kill the process and restart if your mh/s go way down?
