Hi thanks.  I have it plugged into my monitor at the moment.  Working fine.  It also benchmarks pretty well compared to my other two 7850's so I believe it to be running at default clocks.  Using AMD 13.4 drivers, Sapphire Trixx utility, and GPU-Z.

That particular message is for thread concurrency. I usually run my two 7850's at 4096 at intensity 12. For any higher intensity, 8192.

Thanks for your input.  I just tried 4096 intensity 12 and same crash.   

Thanks for the response.  I appreciate you taking the time to ask questions.

I have 2 Sapphire 7850's.  This one is 1GB and won't mine scrypt.  The other is 2GB and does it quite well.  Overclocks well also. 

Running GUIMiner overlay, CGMiner engine.

Overclock, under clock, default clocks, does not matter.

Thread concurrency: 12404, but have tried various values as suggested all over the internet. 8192 all the way up to 12,404.
Worksize: 256
Vectors: 1
Intensity: all values from 10 to 19.
GPU threads: 1

All other settings are default GUIMiner settings.

On two different motherboards I got the card to clock 3 to 4 kh/s.  No strange messages.  It keeps mining along, but never goes higher than this.

On the other motherboard it crashed CGMiner and gave a windows program error message.  Here is the output I get from CGMiner:

Tonight was the first time I have seen it crash and give this error message, but it's in its third motherboard.  Not sure why this particular card is an issue.  I've got 6 other various cards that have all worked flawlessly. 

I have futzed with this card every way I know how and consulted the almighty Google gods for advice on numerous occasions.  My next step I think is to burn it.  Or nuke it from orbit.  It's the only way to be sure.

I really wanted to post this in the mining area but it pertains mainly to scrypt and altcoins.

I've got a really strange one that I am unable to figure out.  One of my GPU's is a Sapphire HD7850 1 GB purchased new about two months ago.  The card works fine in benchmark testing and will hash SHA-256 with zero problems.  My issue?  The card flat out will not hash scrypt.

I have been mining for a while and am moderately experienced and comfortable building and rebuilding rigs.  I have other 7850's that I use, along with 7950's and 6850's so I know how to configure miner software, overclock, etc.  I have had this card in various slots in 3 different motherboards and I get the same results.  Either CGMiner crashes, or I get a hash rate of 3 to 4 KH/s.  All machines had ample memory and were running other cards with no issues.

I am out of options with this card and not sure what else to do.  I really can't RMA it as it will run games just fine.  I can mine a bitcoin or two with it but it's really not profitable to use it for that.

Anybody had any experience with this?

Very nice...and no unicorns!   

This is effen great news!  Glad I've been hoarding.  I jumped in with the right coin.

WDC is on the rise.  Best get in now while it's still cheap.  Out of all the altcoins now this seems to be the one that can go the furthest.

 No joke I have won 3 different lotto draws for a total of 1025 coins.  If you are not participating you are nuts.

WDC.  A coin has to have more going for it than just profitability and mining.  I see a lot of work going on with development and promotion of WDC and building a fan base around it.  My perception at least is that it is  well thought out with the focus on becoming more that just something to mine and dump for BTC.  My belief is it has legs.

I mean think about why a coin like LTC has the value it has?  What can the average Joe do with it?  It only has the value is has because we say it does.  Crypto buyers and sellers all speculating.  I don't see any real use for it beyond the small cryptocurrency world we all live in.  The average person doesn't even know what cryptocurrency is let alone can he buy a tank of gas with it.  Hell, BTC is somewhat that way as well other than you are seeing it get some recognition in the real world and a few places are beginning to accept it as a form of payment.  What the hell makes it worth $120? Just cause we say. The market.

Mainstream is the key to winning the crypto wars.  The first crypto who can figure out how to get Suzy Homemaker carrying around a crypto debit card is the winner, no matter what.  At least in my mind I see WDC as understanding that distinction.  It may not mean anything and I may be all wet but that's why I'm going hard on the WDC. 

Derp.  Did you read the thread?  The rest of the world is on the back.

Nice update.  I'm really digging how the community is growing up around this coin.  For any of you interested in what's happening with WDC you really should come check it out.

I dunno but I see the community around WDC and I think it has some legs.  All new coins seem to go through this process so I think it's normal.  

DGC pricing may just be an anomaly due to the above mentioned deep pockets.  I'm not sure that price alone is enough to keep it viable long term.  I think that there needs to more "there" there.  WDC, at least to me, seems to have more "there".

I won 500 WDC last night.  This is the real deal.

Hi!

Come see for yourself.

Wow great news.  Truly there is lots of stuff happening with this coin.  It is interesting to watch all the support for it and the community that is springing up around it.  

There are quite a few smart people involved in the development and promotion of this coin and I think it's worth keeping an eye on.

Really liking it so far.  Nice community and there seems to be a future here for this coin.  Recommend.

7950 = 610
7850 = 334
7850 = 354
7850 = 260 (only sha for some reason)
6850 = 260

Huh...go figure.  Danny Hamilton you're a genius.  I Googled the hell out of my problem for two days and was about to give up.

The next thing I'm doing is getting rid of Multibit.  I read it is the Cadillac of wallets.  Maybe I just need a Chevy.

Anyway, as far as BTC-e is concerned I understand they are not obligated offer any more than a link to the blockchain, which is exactly what they did.  But I dunno, maybe they should hire guys like Danny Hamilton to at least say "hey dumbass, did ya try this?"  After all, I am a customer with choices who may talk about his experience on a worldwide Bitcoin forum that may possibly sway other person's decisions.  Wouldn't it be great if I could say "man those guys at BTC-e gave me outstanding service and even though most of you nubs may think they are Russian Mafia I highly recommend them"?  But I can't say that can I?  Hey, they did the very minimum to close the support ticket.  I guess I should be happy with their bare minimum. 

Danny Hamilton, can you give me a wallet address to send a donation to?  I like to reward those who go out of their way to help when they could have just ignored the problem.

Yes I did.  They were very helpful in providing me the blockchain.info link.   That's it.  So much for customer service.
