I'm so confused   For some reason I thought you = phatk (and by extension phatk2). So your kernel is a modified version of the original phatk?   Where do I find your kernel?   And any flags you would recommend for a 6950?   I'll report back with results

6950's using the new phoenix + phatk2  (clocked 880 gpu / 300 mem)

old: 360Mh/s
now: 364Mh/s

(consistent across all GPUs)

I messed a lot with flags... this is what gave me the highest numbers:


Not sure why, but worksize=64 is what gave me the biggest gain.  Tried all aggression between 10 and 16 as well.  13 yielded the highest.

Who knows what the eventual future of ixcoin is,  but really, I don't care.  I'm looking at this more like gambling... You can earn 'chips' with miners, or you can buy them with bitcoin.  Then you play them on the market (ixchange).  Then you win or lose.   I'm having quite a bit of fun playing - it's pretty addicting.

1. It's created a busy market involving the use of bitcoin.  Bitcoin needs as many uses as it can get.

2. Miners are being siphoned off to this - is that a bad thing?

3. So some guy modified a few lines of bitcoin and called it a new currency.  The guy who invented the pet rock made a killing too.  But he got some traction, and generated some interest.  Good for him.  Wish I would have done it.

4. It will never replace bitcoin.  It's not even a currency yet - nobody takes it except ixchange. (that I've seen).   Right now it's nothing more than casino chips that you can earn with miners or buy with bitcoin and play on ixchange.

I'm sure the created of ixcoin would not prefer to have it seen in this light, but it is what it is.  Maybe someday it'll catch on.  But I fail to see the downside as it is right now.  It's a fun distraction that provides yet another use for bitcoins.

bitcoincharts streams it..  you save the stream to your local machine, then access that every 2 seconds.

You could try:


Output in stream.out will look like:


(trade time in epoch, value in USD, and volume)

Then something like (pardon my rusty mysql, but just showing the general idea... )

My miners went from 355 to 362 on 6950 based systems running ubuntu natty 64 bit.  I tried various flags, and this is what worked best for me:

-k phatk AGGRESSION=12 BFI_INT FASTLOOP=false VECTORS VECTORS2 WORKSIZE=128

WORKSIZE=256 was slightly slower. I tried VECTORS4 just for fun, and it dropped down to 300 or so.

My 6950s are running at 880Mhz w/ 800 mhz memory clock.  (no shader unlock)




Thank you for all of your hard work.  Donation sent.

The interruptiMOOOOOOOOOOOOO!!!

I can't PM either, but it looks very interesting, and I'd like to try if you have any left.

Thanks!

I'm just curious - how much power do you use with 4 x 6970 when mining?

I'm very new at this myself, so take this with a grain of salt...  but I think you would approach it like bartering.   Someone has a bitcoin wallet with coins in it.  You have a wallet able to receive them.  You give them a service and provide them a bitcoin address for the payment. They transfer bitcoins to that address.  After it settles out in the network, you are in control of those bitcoins.   If you want to convert them to standard currency, you use one of the exchanges like mtgox to sell them.  Have the proceeds transfered to dwolla (or liberty reserve or whatever you choose) and then you go from there.   Or, use the bitcoins you received for your work to purchase another item or service from someone else.

As far as advertising, you could try forums or classifieds.. try googling bitcoin classifieds.

Lurker turned poster ...

So a couple of weeks ago, I met up with a friend I hadn't talked to in a while.  He gave me a gold bitcoin (not sure where he got it?), and went on to explain what bitcoins were.  Of course, I had all of the usual reactions.. "Sounds like a scam!"  "I now declare that grass grown on my property is worth $20 a blade"  "Who on earth buys them?"  "What are they good for?"  etc.. etc..  Being a true geek, I started asking about how to mine them.. and, well, to make a long story short, I ordered 2 6970's, and another 10 which show up today. 

My rough plan is to keep half, and spend and/or sell the other half of coins mined.  I think spending them at retailers which accept them is an important way to keep the economy going, so I'm definitely all about that.   I'll consider this whole experiment a success if the amount I spend and sell add up to the amount I spent on hardware.  From what I'm reading, GPU mining won't be viable for too much longer, but hopefully that point is far enough off to make this hardware investment worthwhile.

From a newbie's perspective, the biggest problem is reliably converting bitcoin to USD.   I need a good way to do that.  I know about mtgox, and dwolla.. and/or liberty reserve.  But all of that seems rather fragile, and I can't find any good alternatives.  Ideally I'd like a good solid way to convert a portion of bitcoins to cash and deposit the proceeds into an internet bank account with bill pay (so I can pay my electric bill, among other things).

For work I'm a unix admin.  Planning on helping people with linux stuff on the board here, once I'm released from newbie jail

I guess that's about it!
