huh? I was talking about the 5850. The 5850 is 145 right now on there. I've seen people say that the sapphire 5850 can easily achieve 400 mhash with no over volt. So for 5 dollars less you get at least 100 megahash more. |

I almost ordered one, but shipping was $17... and for $161 it puts me on the fence waiting for the wind to blow.
As the above person mentioned the shipping barley goes up as you get more. I got 5 and the shipping was 25. So that means they were 150 which is still amazing. |

Not sure about the m1730 but I got a m1530 from dell back 3 years ago it was a horrible design and heat fried the parts all the time. This happened with two other friends too. Thank god we all got the extended warranty lol. Dell did so many replacements we all got brand new laptops for free I got an alien ware  Just curious do these run any better now? |

Unless you post details I doubt any one can help you further with what you have. he doesnt have one.. yet I went out, bought me a cheap, but decent card and through it in a computer that I have.
He said he got rid of it now but from the information I had at the time he did have a card. Never ever buy from best buy all they do is rip you off. Newegg has 5570's for basically half the price. |

I don't get paid til next week  Oh well, I already got a Sapphire Xtreme 5850 last weekend from Craigslist. These cards FLY. OC to 1000+ easy at over 400 MH/s. Get them while you can! Gotta hate biweekly pay |

Hmmm... the "(here)" above in my OP was suppose to be a link to that page. Yes, actually selected a card that had one of the ATI chips in it. I can't recall which one it was, but it was suppose to perform at around 150M/hash.
Pretty sure your just doing it wrong if speeds are posted for your specific card. Unless you post details I doubt any one can help you further with what you have. |

I'm curious if there are any cards using PCI slots that can be used for mining?
Maybe even a PCI to PCI-E cable adapter, would something like that work if it exists?
32-bit PCI - PCIE converters. SHould be around £15-£20 While you could do this most likely with the added cost you might as well go to the next mobo up. Also I'm not sure but I doubt it would be safe to run a gpu at full capacity through one (I may be talking out of my ass). |

Homie here is stealing credit from someone in the newbie section (to try and get donations).... The original posting.Just wanted to put this up here since the OP from the original probably can't post out of the newbie section yet. He actually wasn't the first  For price it is! But, it's currently unavailable at the egg!
A 5850 would be better too! But, again...
I found a place online today with the sapphire 5850 on sale for 145. Such a bargain  And I guess first person to say where was this guy Yes... 5830's are 129.99 @ newegg and are going to get around 300mh. My 6870 tops out around 286 and costs 40-50 more
ncix us also has 5850's in stock for $145 i believe until tomorrow.

I have no clue where you got $50 for a good power supply. Assuming you want to use the most efficient card(5830) you would need around a 750 watt psu. The lowest good power supply on newegg is around $90 ( http://www.newegg.com/Product/Product.aspx?Item=N82E16817182067). As for the mobo you could get a 50 dollar mobo but I'm not seeing any that wont require risers so add around 36 more dollars to that which is 86. Well, I've been pulling 312 Mhashes/sec out of a 5830 with an 430watt powersupply for 2+ months. (Thermaltake TR-2) Hope it doesn't burn out  The 750 watts is for 3 5830's if your just running one 430 watts should be fine. |

Has any one really tried to push a 6770 as far as it possibly could go? Would the bios on the 6770 possibly make it faster? According to the hardware wiki theres no recorded voltage change.

You must be kidding. $481 for one board? You could buy 7 of the popular Biostar A870U3 for less and that gives you 28 slots for GPUs. (or numerous other options) He never asked if it was a good idea, he asked what boards can do it. I've done a few builds and 3 seems to be a good number where you can get a $30-$50 mobo, $50 psu (good quality). As you go up to 4, 5, 6 you need a much more expensive board and much more expensive psu. The main problem becomes the number of systems. I can build a 3x gpu systems that are cheaper then the 4x gpu setups but is it worth having 2-3 extra rigs to save a few hundred? I have 5 3xgpu, 1 x5 gpu, 1 4xgpu and while the 4/5x gpus were more expensive in terms of dollar per mhash, my next few systems I'm leaning towards 5x gpus. It's less rigs to manage, less space, easier to focus cooling. You can get 6 gpu boards for under 200 as long as you have risers. It really comes down to how much money you have and how much space. If you can only have a max of 4 rigs then I'd go for 5-6x gpu rigs no question. I have no clue where you got $50 for a good power supply. Assuming you want to use the most efficient card(5830) you would need around a 750 watt psu. The lowest good power supply on newegg is around $90 ( http://www.newegg.com/Product/Product.aspx?Item=N82E16817182067). As for the mobo you could get a 50 dollar mobo but I'm not seeing any that wont require risers so add around 36 more dollars to that which is 86. 86-mobo+risers 60- case 90-psu 130*3 -5830 30- cpu 10- ram 10- flash drive =676 330*3/616=1.4645 95- mobo 60-case 12*6-risers 200- psu 130*5 -5830 95 -6770 30- cpu 10- ram 10- flash drive =1222 ((330*5)+230)/1162=1.5385 If your willing to show a mobo that doesn't require risers for 3 cards at 50 bucks show me and same goes for a quality psu at 750w for 50. I'm not sure if those exists however. |

But that would also mean more CPUs, PSUs, RAM, HDDs, etc. which eventually would likely total more than the one system build.
I haven't run the numbers but I'm almost positive it isn't justifiable because you can get 6 slots for less then half. That means your paying 280 for 2 extra slots which is definitely more then all the other parts required to build a server. Also if you argue the psu should be included keep in mind that with 8 gpu's you would most likely need 1500+ watt psu and those things are fucking expensive. Ummm... You'll need at least 2 very good PSUs if not even 3 if you want to run 8 GPUs within efficiency range. I said 1500+ I realize you cant really get higher then around 1500 and you would need more. Also you technically can put 8 5770's on one psu That being said you are just making my point more concrete and proving its not worth it to mine 8 gpu's on one board. |

I'm confused why do people like the 5770 over the 6770 can any one clarify this for me? A quick look on newegg shows it is much cheaper and it produces less wattage and has the same amount of stream processors?
5770 is faster than a 6770 despite the naming. The old 5xxx series architecture is more efficient for GPGPU tasks. A 5770 oc'ed will usually do 10-20mhash more at the same frequency compared to a 6770 Besides, 5770's these days run for about $79 to $99 not $130, which makes it a bargain if you can find one, easily one of the best $/mhash ratio (at best, $70-80 dollars for 200mhash at 960mhz) Newegg displays absurd prices for products often out of stock or not produced anymore Anyways, out of those options you listed, the 6770's are most cost-efficient ah alright is there any site that doesn't mark up like crazy or do I have to search for good deals that just randomly pop up? |

If we went with the cost excluding the 9 extra chassis and including your price cut we have a cost of 2,285. Assuming you get 820 megahash per card thats 1640 megahash.
1640/2285 is .71 megahash per dollar.
An efficient 5830 rig could get 1.36 megahash per dollar so it would cost about 1,205 dollars for the same speed.
having played with the numbers a lot myself, I'm not sure where you get 1.36 MH/$. If you're willing to run open air, and have all your hardware off one motherboard and buy PCI-E extenders, you could run (8-eight) on a single board, but then that decision implies other expenses, like 8 x $25 PCI extenders with power-taps to keep from cooking your motherboard, and framed cases, BIG power supplies, and motherboards that will support 8x PCI-E, all of which add to the bottom line, and offset the savings of the cheap cards. I put the rough build cost on a machine like that at about $2500 by the time you include EVERYTHING you'd need, which is still around $1.07 $/per/mhash for 2400 Mhash. In the example you give of a 1600 Mhash, which, at 300Mhash/per/5830, takes 5+ cards (depending on OC levels), which is still $650-$800 worth of cards, depending on your sources. I'm not saying including the cases isn't hurting the sale, I'm saying that even $1/per/mhash is an aggressive goal.. 6990's have other advantages like Mhash-per-box, but $-per-mhash isn't one of them. Here is a rough example. 650-5x5830 10-1 gb ram 10-flash drive 75-5*extender cable 30-cpu 195-mobo(probably could go cheaper) 240-psu 60-open frame case made out of aluminum tubing =$1,270 5 5830's set up in an open frame case can give you close to 330 Mhash (5*330)/1270=1.29 That was a quick calculation it is in no way the most efficient you can go. The problem I found with going higher then 5-6 cards is the parts in the server like the mobo and psu get exponentially more expensive so thats the sweet spot. |

It's proven reliable because it's very easy. Most people do it without any mathematical modelling and can come within 10%. I disagree with the OP and his > 15% prediction, and we'll see who ends up being right (I've proven more successful thus far, but no one is perfect), I've done better than most just based on observation. The real difficulty lies in predicting farther out into retargets even farther down the road. For example: Block Number: 137088
Difficulty
Lower Extrema: 1831645
Lower Quartile: 2153150
Median: 2851755 Crazy ass far off. Even the lower extrema wasn't really close. The previous one did a tiny bit better, but not much. When your error bars are almost 100% though that is hardly a statistically valid prediction, is what I assume that other fellow meant to say (especially when it is still wrong). If you call 6.3% crazy far off then I suppose you are right. But the figure you quote is for a different case, which was a forecast four re-targets out, I don't yet consider forecasts out that far to be reliable... Try and keep up. But even so, if you know of a method that could do better for a Difficulty forecast that is reliable four re-targets out I would sure like to know what it is. So far nobody is stepping up to that challenge—I continue to work on it. Like he said previously it's very easy to predict one or two difficulties out that's why you have for the most part been accurate. I'm pretty sure I could be within 6% if I guessed only 8% increases for the next two difficulty changes and then I would be just as good as you. |
