My 5830 does 280Mhash/s using -v -w256 at 950mhz and stock 1.168V it also got over 300Mhash/s at 1030Mhz and stock volts but there was one crash after a while so I bumped it down for stability.

true story...

wol-va-FAIL searches CL for "5850", finds an ad 2 months old for a complete rig with two 5850s, wol-va-FAIL emails dude and asks how much for one of the 5850s in his rig, dude responds and says he's not selling just one, either take both for $220 ( :eek: ) or none at all, wol-va-FAIL tells him this week he can only buy one (bills were paid leaving little disposable wol-va-income), if he can wait until next week wol-va-FAIL can snag both, he says okay and leaves wol-va-FAIL his phone #...

wol-va-FAIL calls a few days later because he has a friend that has agreed to float wol-va-FAIL the extra cash for the trade, in his retardery wol-va-FAIL has inadvertently reminded dude to REPOST his sale on CL...the cards are gone already...

FML...

wol-va-FAIL is now extremely wol-va-SAD and not wol-va-GH/s...

LOL nice. I havent heard back from dude after I told him I'd buy it. He had them up for trade for a phone, told him I didnt have a phone but I might be interested in buying them for cash, asked him how much. He replied with $125. I probably reacted too quickly and now hes having second thoughts.

Really hoping I nail this one.
 
I wonder if a CX430 psu can handle 2 5830's going at full tilt

LOL we're about to find out.

it should be ok, as when mining everything but the video cards is at idle. You wouldn't have much headroom though.

Yes the bitcoin market rebounded from yesterday. It goes up and down often as of late. I cashed out 500 bitcoins the other day at 27$ a bitcoin. I wake up the next morning to see the rate at 10$ something i was like YES! haha. I will be ordering some new hardware here soon.

4 pcs going full tilt 24/7, and a 5th computer (my main pc) going when not gaming or other things. 4-5750's 1-6870. I crank out about 14 coins a week. Will probably pick up 4 more 5750's put them in crossfire and pick up another 6870 and put it in crossfire.

who said mining wasn't profitable. My friends thought i was crazy until i showed them my bank statement.

I think my friend is using the -v w128 flag and is getting over 300 MH/s at a lower clock rate...
 
i meant that generally
i think its pretty average
but yes i should quote since the thread moves so fast lol
btw setting up namecoin is similar?
im thinking to use my i7 920 at 3.6 GHz for namecoin and 5870 for bitcoin

any certain flags and switch to something betteR?
on 7x64
will have my 5870 running today and 6950 next week
Click to expand...

Try using Phoenix 1.48 with the flags: -k poclbm VECTORS BFI_INT AGGRESSION=14 WORKSIZE=256. You'll also want to overclock the core as high as you can get it because every 20Mhz or so makes a noticeble difference in Mh/s.
 
oh i see, ill go experiment after i setup my 5870
be back in a "bit" sad pun lol
thanks!

Check your actual memory speed in the graphs in Afterburner. I've found that trying to set the memory lower than 800 on my 6950 doesn't actually work and resets the memory speed to stock.
Click to expand...

Mine won't show anything below 1250mem in the monitoring window in Afterburner...but I tried a round of 3dmark11 at 350mem to see what happened and it sure seemed to make a difference in my 3dmark score.
Graphics score 350mem set (1250mem reported in AB): 4674
Graphics score 1250mem set (1250mem reported in AB): 5064
I'd say it's working. GPU-z seems to be able to properly poll memory speed as low as you want to push it FYI. 900core for both of the above tests (the fan at 60% was annoying the crap out of me last night so I clocked down from 940/1.175vc to 900/1.1vc and things are MUCH quieter. That little vcore change also saved me almost 40w and only cost ~20Mh/s).

Final, triple checked, performance verified results confirm memory freq on my 6950 doesn't make more than a 1.25% difference in hash speed OR power consumption, well within standard fluctuation ranges. I see no point in opening afterburner eleventy times to change a setting that does not matter (at least not on my 6950, perhaps it did on other/older cards). I of course invite peer review and confirmation of my results by other 6950 owners.

from what I hear namecoin is the better mining option right now as they can be traded for bitcoins, with the exchange rates it actually favors switching to namecoins, a friend of mine already has switched and found two namecoin blocks yesterday (100 namecoins) while hashing at 325MH/s (yes, the difficulty isn't as high at namecoin yet), which made him more than 1 BTC whereas he would've made about 0.5BTC bitcoin mining, I switched about 170 MH/s (my 4870/4890 crossfire rig) to his namecoin miner using the same poclbm miner I use for bitcoins, just adding his ip instead of Deepbit and using his user and pass...

Is there any gui for namecoins? I am trying the mining right now. I see how coins can be transferred but not sure how to tell what I have if/when I get a block

as for how, download the namecoind client,

http://dot-bit.org/files/namecoin_w32.zip

C:\Users\xxx\AppData\Roaming\Namecoin\bitcoin.conf
rpcuser=xxx
rpcpassword=xxx
rpcport=9332

start the client

then poclbm.exe -d0 --port=9332 --user=xxx --pass=xxx -v -w128 (or whatever)

a list of commands with namecoind help
can be run in a separate section for queries

Anyone notice the price hasnt fluctuated at all in the last hour or 2? Looks like no trades have been made. Is this common?

Still waiting to hear back from the dude with the 5850. Making me a little nutty - factory overclocked Sapphire Toxic. Grrrr.

done, thanks!
 
look guys, don't go crazy buying gear thinking that you'll be mining profitably forever, at some point you WILL hit the wall (probably sooner than you think, much, much sooner), so if you're investing to get what you can now fine, but don't keep investing thinking that the generation rate will stay the same, this is a predictor chart for someone pulling about 1GH/s starting today and the bitcoins they can expect to mine, it also takes into consideration two assumptions...

- 1.8 BTC/day until the difficulty changes
- The difficulty grows at a constant 45.7% per period, forever (this is rather low if you ask me, a few days ago I did this chart and it was only 23%...ouch)

be careful fellas, you are not gonna mine as many bitcoins as you think you will, I guarantee it, ebduncan had 500 bitcoins to cash out, that's really cool for him, but he obviously was mining (maybe trading too?) way before any of us, you will NEVER mine as much as he cashed out with your rigs...guaranteed...unless you're running a pretty big farm...

don't get it twisted fellas, the BTC total on the right column is not the amount you will mine during that 10 day period, but the total you will have mined up until that date from this date forward...

06/15/11 5.54 BTC
06/25/11 17.71 BTC
07/05/11 26.06 BTC
07/15/11 31.79 BTC
07/25/11 35.73 BTC
08/04/11 38.43 BTC
08/14/11 40.28 BTC
08/24/11 41.55 BTC
09/03/11 42.42 BTC
09/13/11 43.02 BTC
09/23/11 43.44 BTC
10/03/11 43.72 BTC
10/13/11 43.91 BTC
10/23/11 44.04 BTC
11/02/11 44.14 BTC

please don't take this predictor as discouragement, please continue to mine, as they become harder to get the value will almost assuredly rise, at the 11/02/11 date I've seen predictors value 1 BTC at around $6,000 USD, at that rate even partial amounts of bitcoins are valuable, maybe at that time eb will kick himself for selling them so early and so cheap (sorry ebduncan, had to throw that in there)...

sorry fellas, I'm not trying to discourage people with this post, just trying to let people realize that the days of mining thousands, or even hundreds of bitcoins is gone unless you have a pretty serious farm going, it COULD still be profitable if bitcoins become more valuable as their generation numbers decrease, so even at the point you're mining less than 1 per month, even that partial BTC may be worthwhile...

Mine will run around 1000Mhz at 1.174v before it starts giving me problems with locking up. I could probably get it a little higher if I gave it more volts and got rid of the reference cooler.
 
so..... I am thinking it might be a better idea to hoard your namecoins. Right now the difficulty is real low, thus the 50 to 1 ratio. But that will increase, and eventually reach a parity with bitcoins. Then you might be looking at a 1 to 1 ratio. Considering all the resources being put into mining that day might be sooner than anyone expects.

Yeah I'm giving up on this.

please don't, you never know how valuable they may become, my suggestion is to just mine (like I am) and see how many you can mine while the gettin' is still reasonably good, then backup your wallet when you finally decide to call it quits...

then watch the exchange rates and maybe profit later, I've also seen predictors peg the value of one BTC in the thousands at those later dates, the harder they become to mine, the more valuable they'll become...

all I'm saying is think through all of this first, especially with investing in gear, hell, by the time it becomes harder to get bitcoins the value may actually make it worthwhile, you just never know...
 
Is the Namecoin pool down right now? I can't connect and site seems to having trouble as well.

there is no UI. Next run your miner. If it starts mining you are good. You run a second namecoind for queries
 
so let me get this straight
after creating bitcoin.conf
i start another instance of guiminer? since my first is with my 5870
then my second would be with the i7s instead?

i was thinking about joining a pool and need a namecoin address but i cant seem to get to that step?
 
Namecoin pool appears to be down currently.

Also people forget or don't realize that bitcoin mining is designed from the ground up to be making a bit of money yet "just out of reach". Like a donkey to a carrot. It's not bad, else there would not be any value in it.
 
oh i see
ill go do solo mining then

then its just this for solo?:

No, hoarding Namecoins is the completely wrong thing to do, the current ratio of NMC to BTC has not and will not remain static (Edit: IIRC last night 1NMC=0.015BTC, and now it is 1NMC=0.013) . People do your research, the info is out there:

What percentage of stale/invalid shares are you guys getting for the Namecoin pool? Mine seems too high so I'm wondering if its a problem on my end. Bitcoin mining using poclbm with the BTC Guild pool my percentage of stale/invalid right now is 0.569% but Namecoin mining with Phoenix on the Namecoin pool I'm getting 6.243% of my shares coming up stale/invalid.
