Cryptocoin Mining?

dang that reminds me I should check that

sonofabitch both my miners have been down for 10 hours arg...

Im getting into pure currency speculation by dumping one of my 5850s and buying coins with the proceeds.

You think they're going to bump back up in price? I don't even know what they're selling for these days. But, I know that drug trading site, Silk Road, uses them. So as long as that site is up and running I think these have to have some value. Who know the illegal drug trade would tie into video cards somehow.

As long as I see more hash power being added to the pools.....and the difficulty increasing..it makes me think it could be around for a while.

I have been to the silk road, and that cant be all that is driving it.

What'd you buy?

What'd you buy?

Window shopping, of course

I actually read somewhere that they were going to be more like the 5xxx series than the 6, architecture-wise. Though, of course, I now cannot find the source of that information, so pretty worthless. Time will tell, I suppose.

They wouldn't go through the trouble of switching to VLIW4 and then switch back to VLIW5 for their next card. You won't see a major architecture change until the New Architecture is out.

hovering around 17

I was hurridly trying to get $$ into dwolla so I could buy in the few days it was around 10-12 after the mtgox shutdown but it took too long

Once I hit my ~10 coin goal (sold 3 right now and number 4 is 75% done) I'm not sure what I will do. Probably shut down the mining (except the one 5870 box) and maybe do a little buying and selling depending on what the market is doing at the time.

Yeah, that makes a lot of sense actually, should have thought of that myself. You are right, unless AMD changes the trend in their architecture advancements the 28nm transition could very well not be a help to the BTC miners.

i remembered reading that fermi's switch to compute architecture resulted in poorer dx8/9(pixel pipeline) performance than gt200. assuming amd's gcn simd pays a similar performance penalty, the integer output per core/cluster could very well be worse than cypress/cayman. but if 28nm allows them to stick more of the clusters on die then the performance should still increase by some small factor.

I am personally hoping it is worse so we can stabilize the total hash power and difficulty levels off.

if it is greater, then everyone will be off to the arms races again. and since you can amortize the cost of multiple cards at launch, miners would buy up everything day 1 and jack up prices to the sky. the first whiff of southern islands hash performance will decide it all.

Noob question here. I've downloaded the client and started running on a 6870 (edit: whoops, overclocked @1000/1200)
1. I'm getting about 280 Mhash/s. Is it in the ballpark?
2. What does "Accepted shares" mean? I assume that's the tally of work, then how does it translate to Bitcoin? (i.e. exchange rate?)
3. I've got one stale/invalid share. What does it mean?
4. What's the best flags to be used for a 6870? I'm using -v -w128 -f128.

Lower the memory clock to 300MHz since mining doesn't require fast memory clocks. 280 Mhash/s is about right for that card. Don't worry about stale/invalid shares as long as you don't get too many of them. About 1 stale share per 100 accepted is a good ratio. The flags I use with my hd6870 are -v -w128 -f120.

1. Ballpark? Yes, but you could probably do better. Based on the hardware comparison wiki you should be closer to/over 300 at that clock speed. Try the phoenix miner. Google can get you instructions for getting set up with it. Check the wiki to see what miner and flags other 6870 users are using for best results.

2. How shares translates depends on what pool you're using, but just check the pool's page to see how many BTC you are earning for each block found.

3. Stale/Invalid rate should be between 0-3%.

4. See #1 above.

Finally got the 5830 I traded my GTX460 for. Up and running at 980/650 and getting ~295Mh/s. Stock volts, fan at 77%, temp at 73C.

Afterburner won't let me underclock the RAM below 500. Anyone know how to get around that? I figure it might make things a little cooler, although its pretty cool here this time of year, so having a little space heater in the office isn't the worst thing.

I had it clocked at 500 initially, but was having trouble getting it to OC even to 850. Then I read somewhere that mem clocks between 400-600 made the card unstable, so I upped it to 650 and things are running pretty smooth at 980 core. Things started to get a little shaky at 1000.

Hoping that the current estimate of only a 10% increase holds up and I can stay profitable for a while. Electricity is freakin' expensive down here.

Reposting this in hope of some help.

EDIT: Nevermind. I figured out I had to uninstall the Catalyst Control Center. It is apparently not friendly to mining, even if you don't touch it.

 

[Dark Shroud]

Is anyone else having trouble getting into Mt Gox? I've tried the claim process and the reset password option with no luck. They must be really swamped. I wouldn't care so much but I actually want the 2 Bitcoins I had in the account.

And yeah cards are in demand now. I'm going with 6800 series cards when I get my mining rig set up. Just because the 5770s aren't cheap enough.

i've had 5770s for around 60-70. THey're amazing value especially when you run 4 of them on a board w/ risers.

That -f128 flag you have slows you down a good 20 or so mhash but makes the computer usable (except for flash video on mine, then it crashes). Remove that flag if it's not your main pc to get the fastest rate.

I use CCC on all three of my miners to watch temps. Are you saying this slows down the process speed?

2. What does "Accepted shares" mean? I assume that's the tally of work, then how does it translate to Bitcoin? (i.e. exchange rate?)

Accepted shares on your GUI Miner means just about nothing. The reason I say this is because it's a combination of how long that miner has been operating.

In regard to what an accepted share means, it means you received and processed a share and it was accepted by the pool. Accepted shares go into the calculation to see how many Bitcoins you get per block. The equation is a simple: (accepted_shares / total_shares) * 50 Bitcoins. This is calculated once a random user solves the block, which can vary from hours to (literally) seconds.

EDIT:

As another user said, look at accepted shares on your pool.

I use CCC with zero issues at all, well, unless its running and I RDP into the machine, then it crashes

 

[Chiropteran]

I don't have issues with CCC either, although I prefer to use MSI Afterburner for watching GPU temperatures.


edit: Has anyone tried this registry hack?
http://foldingforum.org/viewtopic.php?f=52&t=12485

I have just been manually moving my monitor connector from card to card to start up my miners, but this would certainly be easier. I was about to build some dummy plugs. If I get a chance tonight I'll test the reg hack.

 

[x3sphere]

Hmm, so I just tried using ATI tray tools to downclock the memory on my 6970. A t400-600 MHz it started artificating all over the place, went back to the default and it's fine now. Did I damage the card by doing that though? Seems anything less than 700 MHz causes it to artifact.

Very strange... after doing that I now can downclock lower than 1000 MHz in CCC, went to 500 MHz and it's fine. Doing the same in ATI tray tools causes artifacts.

That -f128 flag you have slows you down a good 20 or so mhash but makes the computer usable (except for flash video on mine, then it crashes). Remove that flag if it's not your main pc to get the fastest rate.

1. Turn off hardware acceleration in the flash settings while your computer isn't mining.
2. Start mining
3. Start flash video
4. ...
5. Profit!
