we need more ppl to get out of it so difficulty won't increase : )

They're getting out in hordes I see. On BTC Guild the number of users jumped from 8000 to 10000 in just three days. If they continue to "drop" from mining this way, we'll soon have 100% difficulty increase.
 
what is everyone using to adjust clockspeeds?

i looked for sapphire's trixx tool but the webpage is dead or bad link. the msi afterburner seems a little out of date or im looking in the wrong place.

i'd like to downclock the memory while mining to see if i can reduce power draw. ccc only lets me go down to 1200 on my 5870 and 900 on 5830.

will afterburner conflict with amd overdrive?

I'm curious about this too. I want to downclock the ram on my 5870 since that will likely be mining 24/7 for the foreseeable future.
 
For anyone using guiminer in windows, what switches and clients are you using on which cards? I have a 6970 + 5870 in the same system, and run Phoenix on the 5870 and openCL on the 6970. I think OpenCL gave me more hash on the 6970 than Phoenix did, unless I'm not doing something right. This is a dedicated miner, so whatever I can do to milk it as far as switches go would be great.
 
What happens if the pool sends you coin(s) but your wallet program is not up and running? My box that had the wallet open restarted due to an update and so the wallet was not running when I received a payout last night. Will these still show up later?
 
yes it'll show up,i withdrew coins and shut the comp down and changed motherboards and when it was up and running my coins were there

Awesome. It was not a ton but I still did not want to lose them. At this point I've earned myself a whole $32.... wahoo!
 
If i cash out right now at 17 dollars per coin it cost me about 20 dollars for a xfire motherboard and 5830 and my goal is to pay those off and have enough for windows 7.I said when i drop below .35 btc i'll quit and i dropped to .31 but its been slowly going up and now i'm at .38

Nice! I'm just using hardware sitting around (6970, 5870, 5770) to mine. My goal is to earn around $150-$200 in total to buy a new case. I want to finally replace this aging P180 that just does not cool gpus well enough and has terrible cable management. If I end up making more than that I'll spend the rest on a nice bottle of scotch 😀
 
i was having a problem cooling the top card,i put a panaflo 120x38 114 cfm in the side panel and i still was not happy with the temps.I dug out an old 24 volt blower and run it at 12 volts it's pretty quiet an out performs the panaflo.It's very effective but not the nicest looking solution http://imageshack.us/g/5/bloweron.jpg/

-v -w128 on guiminer on a 6950 and 5870 here, that gave me the best results

So this is why it's harder than hell to find 6990s and even 5970s everywhere?

Figures. 🙄

I think that 6990's are sold out because they're the fastest gamer cards on the market right now. They're too expensive to be practical for bitcoin mining.

Now, if you're having problems finding old 5830's... That might be bitcoin related.
 
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.

Could be the confluence of a number of minor conditions coming together to result in one major outcome (supply not meeting demand).

The Bitcoin mining "fad" is certainly fueling a non-zero demand for 40nm gpu gear that AMD might not have predicted and thus would not have factored into their wafer start allocation models for inventory management (something that has a healthy 3 month lead time after all).

[note: I am referring to BTC mining as a fad only because of the accepted notion that eventually it won't be cost-effective to pursue mining...BTC's themselves may or may not be a fad, obviously lots of people aim to ensure it does not become merely a fad]

At the same time AMD may well be intentionally ramping down their wafer start allocation for 40nm gpu's IF they are on the eve of ramping up 28nm gpu wafer starts. They have to manage that transition, for their sake as well as the AIBs and resellers. No one wants an inventory overhang when 28nm starts making the headlines.

Demand for 40nm won't go to zero, obviously, but there will be an inescapable immediate reduction in the perceived value of the 40nm gear once 28nm is on people's minds.

Just saying, there may not be any one dominant reason for the supply not meeting demand, but a lot of little things may be adding together here to create the result.

One thing is for sure, when 28nm arrives, owing to its improved performance/watt there will be a sizable immediate demand placed on the GPU's for the sake of BTC mining. Gamers may be left in the cold in a way that will make the supply issues of Cypress and 40nm seem like good times.

It's certainly possible. I'm kinda hoping the 7 series is worse at mining, so we don't have this problem. I am basing this off the fact that the 6 series is slightly worse at mining compared to the 5 series.

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 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.
 
I'll probably continue mining until it's not profitable as well. I buy most of my BTC, so mining gives me that extra little bit that really helps out in the end.
 
Just got my power bill. I was watching the meter outside the house, so no surprises there. Turns out I'm actually paying .046 / khw + fees = ~.06 kwh/hr, not .09 + fees = ~ .12 kwh that I had been using to estimate profitability. Yay for cheap power!

Anyhoo, this does change things. The rig is back churning out bitcoins, but now I'm looking for more cheap 5830s, pcie extenders, etc. Since the current hardware was bought for gaming and is paid for I am looking at the ~$250 (-30 for power) in my dwolla account as more budget for hardware expansion.

Also turns out the old P35DS3L has *4* PCIe slots total (1 16x, 3 1x) That will get repurposed to host 4x5830. My i7 motherboard has 7 total PCIe slots, but I'm not sure I want to feed an i7 920 as opposed to a downclocked E2180 for 3 more slots.

Fun hobby ahoy!

Edit: holy crap, not a single 5850, 5870 or 5970 in stock anywhere. Cheapest 5830s are closer to $200 than $100. Even 5770s are getting expensive. F that.

Argh!!! Stupid Windows updates, gotta remember to turn those off. Nothing like noticing 2 of your 3 miners are down due to updates sometime in the middle of the night.
