Bitcoin / Mining / Re: Don't expect another 8% Diff increase -- expect more

I would say however that in my personal opinion, price is a stronger motivator for difficulty increase than simply awareness, looked at individually. Just knowing about bitcoin doesn't really motivate most people stuck in a fiat currency system unable to imagine life any other way (most people aren't all that smart), and the minimal profit made per card per day from mining doesn't really inspire many people (Oh I make $15 a day from my triple radeon rig? so what?). But when price takes off both those who are already invested get gold rush fever, and those who hear about magical money making inventions and ridiculous profits for doing nothing want to jump on board
Well, of course when you factor in such elements as "human nature", you can draw a circumstantial relationship between price and difficulty. But let's not forget that the difficulty was raised several times before there were even any exchanges, and that movement was driven primarily by awareness. We've already seen the scenario you describe where the price of the BTC spikes, and since then we've seen the price progressively diminish, with no corresponding drop in difficulty. In fact, none of the difficulty forecasts I've seen has any difficulty decreases at all. I think it would be more accurate to say that difficulty does not follow price, but it is affected by it. |

So what you're saying is your model can predict bitcoin pricing 20 days out? That's... amazing.
Because price is what drives difficulty. I'm becoming increasingly convinced that price has absolutely nothing to do with difficulty. I subscribe to the idea that "awareness" of Bitcoin is what drives difficulty, not including natural net growth of course. |

If anyone wants to believe you can OC to over 1ghz from 725mhz with stock voltage be my guest Why not post your record along with screenshot proof to https://en.bitcoin.it/wiki/Mining_hardware_comparison & beat the next miner who had to raise voltage to 1.250V just to sustain frequencies beyond 1ghz for 420mhash, and that's a premium chip which OC's better than 99% of 5850's out there I just bought a 5850 this morning and it's been going at 412 MH/s @ 1020MHz @ 1.088v for the last four hours or so. I want to see if this thing is 24/7 stable at these settings. |

I just got my shirts in the mail (thanks Gabriel!) and they're AWESOME!!! Very high quality heavy cotton construction and they feel comfy. If anybody is on the fence about picking up a shirt or three from SquareWear, I'd say DO EET! Not only will you get a pretty kickass shirt, you'll also help stimulate the Bitcoin economy.  Wish I actually had a 6990 FML |

yes I got them all back and made them extremely hard  I'd go into each of your compromised Email accounts and make sure he didn't set up any CC addresses to get copies of your Emails. Cuz if he did, all he'd have to go is do a password recovery for whatever you used your Email to register with and he'd get a copy of the recovery Email. |

Bitcoin / Mining / Two 5870s, one gives higher stale rate than the other?
|
on: July 21, 2011, 04:33:13 PM

I don't get it. I have two 5870s (on Diamond reference and the other a non-reference Sapphire) clocked identically and using the exact same Phoenix parameters. They run the exact same MH/s rate (+/- .2 or so). However, the Sapphire always has a lot more stales than the Diamond does. Is this just pure luck, or could it be something hardware-based?

same with 5830s?
I am seeing a super deal right now, however the stock core of that card is 800MHz, and most good hashrates ~300 are reached with 880 - 1030 MHz.
It's hit or miss with the 5830s (well, any card really). Some of them can OC to 1050 MHz without a problem. Others choke on anything past 960 MHz. YMMV |

I have 1GB 5870's and they hit 450-460 MH/s no problem, right out of the box. That is, with the proper overclock.
did you flash the BIOS to OC? or just use catalyst? clocktweak? RBE? No re-flash necessary. Just unbox, plug in, turn on and go. I used AMD GPU Clock Tool to set the overclock and then MSI Afterburner for fan control. I think re-flashing is only necessary for 6950s. |
