Even if you use Bitcoin through Tor, the way transactions are handled by the network makes anonymity difficult to achieve. Do not expect your transactions to be anonymous unless you really know what you're doing.

I just got 4 more of these. Since i have so many i decided to put together another computer. They run 1050/300, temps 60, fans 35%, hash 285, no extra volts.

this makes no sense #1, i had 7 of these and none were stable at 1050/300. the highest was 1030/300 #2, the temp would not be 60oC with the fan at 35% unless you had an ambient temperature of 15oC and/or some big ass industrial fan blowing right into the case #3, i get 325mhash at 1000/300

Every chip is different. Out of the 4 that im using every one does 1050. Im even thinking about trying for more cause they do 1050 with no problem. With some extra volts they might clock higher.
Where i live has been 40-50F the last few days. Im also mining caseless with risers and plenty of space between each card.
I wish i was getting 325 hash but i am getting 285.

1025gpu/300memory/1.163v is what i start at, will do 325megahash on BAMT, out of 7 extreme 5830 have only seen one that would only be stable at 1015 most will do 1040, its got to be a driver or bad miner flags to be that low
if your using windows I use guiminer and phoenix with phatk2 with similar results -k phatk2 VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 WORKSIZE=256

OK so i have been using poclbm since i started mining and i have never tried another miner. I just tried CGminer and noticed some big changes in my hash. I run them at 1000/300 and was getting around 275K. With cgminer im getting 300K. I like cgminer so far im gonna try for 1060.

I always use the latest. I have tried a few older versions and never noticed any improvement.

because you were using poclbm probably, it definitely makes a difference with phoenix

I didnt see any gains with 11.1 vs 12.3. Two of my cards run at 1060 with no volts. Hash is 325K. Temps around 65 and fans 55%.

yeah its really hard to totally revert the drivers maybe someone else has figured out the trick, I've just started from scratch when I found out 12 didn't work as well. I think it has something to do with the sdk version they install but I'm not sure

Any ideas why windows wont detect a 5th gpu? I tried 12.3 11.12 and 11.1 with no luck.

Are these new, refurbed, used? 25 BTC is a little high for the 5830 market right now. You can buy a used one for $100-110 (~21 BTC) on Ebay. I grabbed one for $92 with free shipping. I'd consider buying one off you for 20 BTC. But I don't really know how buying/selling works on the forum. Or how to avoid scamming. Do you have any references? Assuming all goes well, I'd consider buying a 2nd off you.

Refurbs from newegg. They are under warranty. I have the receipt. $120 is my price. To avoid getting burned use escrow or buy from people with rep. I have references for good sales.

oh, that makes more sense i guess whatever you were using before probably wasnt aggressive enough... maybe using 85% of GPU or something, that would keep the temps down some -k phatk2 VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 WORKSIZE=256 i've noticed when i put the cards above aggression 9, it starts using a good amt of CPU cycles for just minimal gains in hash rate... if I have three 5870's at agg 12, it actually lowers their performance (100% CPU usage).. if I have three 5870's at agg 9, the cpu usage is like 1 or 2%... agg 10 would be about 20%. though i've never tested the actual power draw and whether it's more efficient or not anyway, i've been using some old dual core CPUs I had, w/ one core disabled and the other one underclocked and undervolted.. maybe if you have a better CPU, it wouldnt be so bad.

I see some people reporting 330-350K with these 5850. Im jealous.
