I'm still in the green 'til BTC hits $3, but I have faith that it'll bounce back eventually.

File server, media center, web server, automated torrent bot...

Any file or cpu-based task that is easily offloadable, really.

Even making these outrageous assumption the annual return on investment is 20%. If you no where to get a 20% interest rate on a $1000 deposit please tell us.

You naysayers are foolish. This ain't no  zero sum game. You have to compare mining to all other forms of increase. Obviously at $10 per BTC it's still an order of magnitude over a deposit account.

As much as I'd love to think the difficulty would stay in this area for the next 12 months, I don't think that's how it works.

You're probably looking at "instant" difficulty estimates which mean nothing. The current outlook is 1.94 up from 1.89 -- we're looking at another 10 or 11% increase about 12 1/2 days from the last one.
Instant here being x0.92, "Next" being x0.95. But a lot can change by August 16.

Exactly.  Because we all know it's the gamers who are buying up all these cards.  But for some reason only the ATI/AMDs.  You can find nVidia cards every day all day.  Huh.. they must not be very good for gaming I guess.
Because we all know it's the miners who are buying up all these cards. But for some reason the difficulty is trending down.

You can see just how many of these recently purchased 6970s are mining by looking at the next difficulty prediction. If we did drive them out of stock it was a poor purchase decision it seems, because we're pushing it back towards 1784732 at the moment. Maybe if you wait a few days you'll be able to buy an open box version cheaper when all the panic sellers return some hardware.  Tongue

You poor Americans. A bitcoin miner is a net temperature benefit for at least 7 months of the year in Soviet Canuckistan.
I'm looking forward to not having to use my heat at all this winter.

I'll break even with my personal rigs at the $3 point, but I like the idea enough that I'll probably keep 800 Mhash/s at least up even if it goes below $1.

Why bother???  a 5830 is much better
Personally I wouldn't, but with the 5k series getting harder to find I figured I'd pass on the deal info if someone was strategically positioned to pull the trigger on one.

There's also a [H] deal on the XFX version that includes a mail in rebate with it. After using the code HARDOCPX727B it comes to $129.99 with free shipping.

Nvidia's Fermi architecture was supposed to make their cards more computationally adequate. Look how well that turned out. Smiley
Fermi's a beast for computation. Sadly, just not simple stuff like massively paralleled hashing.

...there are just so much negatives things going for bitcoin right now, and not accepting dwolla is a major one.
Unless Dwolla wasn't the only website that performed such a service, and something else could step in to fill the void.

Y'know, something like: http://tradehillblog.com/2011/07/28/tradehill-is-now-accepting-paxum-transfers/

Now that I recall, you are correct-- I could get the OpenCL software to install, but I couldn't get it to see the GPU hardware, just the CPU.  Sorry, this all happened a few weeks ago and I gave up... but now I'm wanting to try it again.
Sounds more like you didn't have the OpenCL drivers installed for your card. AMD has/had at one point two different versions of their driver packs, one that included OpenCL support and one that didn't.

Looks to be running really smoothly since the update, and it seems our lucky streak is holding up still. Grin

I've only noticed one thing that's funky and even then it's only aesthetic. The "Current Day Shares" column differs for me between what's shown on the Pool Stats page and the Lifetime stats page.

stats.php:

statsAll.php:

But really that's just nitpicking. I love this pool.

You're going to have one hell of a time fitting 3x6990's in a 1U case.

Well I'm mostly a lurker but I'd like to be able to post a comment or two in my pool's thread, or give people occasional tips on video card overclocking, etc. So I'd better start spamming this newbie section so I can be let out.
Sadly... +1.

I happened across an article about it that piqued my interest, then found out I (as a gamer with AMD cards) was in the right place at the right time. Now I'm pumping out ~900 Mhash/s without having invested anything (yet) into hardware costs.

Video card upgrades that pay for themselves? May even turn a profit? Sign me up for that.

A random acquaintance of BitCoin a few days ago, I've already converted what was my hawt little gaming rig into a pretty dedicated miner. Turns out luck was on my side when I picked two 6950's and unlocked them to 6970's. If only I had started hashing with them much, much sooner.

4 Hours is nothing, just reading on setting up Linuxcoin with SmartCoin took that, going back and forth seeing my setup wouldn't work and finally did get it working. Just add trying to find out the best settings for Phoenix and phatk took a good 30 minutes for my cards.
Definitely +1 to that. My only regret after lurking for hours on end is that I didn't sign up right off the bat, so now I have to lurk for four more hours. Tongue

Re: Mhash Fluxuations on Ubuntu 11.04/Windows

on 21/07/2011, 14:17:52 UTC
The software/options you chose will make a world of difference. It took me a few days to find out the settings my 6950's were looking for, but "-v -w256 -f0" in GUIMiner's OpenCL miner seems to net me the most stable results. After -f, I put the device #. So your first card will be -f0, the second -f1, etc. Putting them all at -f0 seemed to make mine fluctuate like you describe.
