I am somewhat concerned by this since I have a large order of singles that still have not been shipped to me. Basically it means in order to stay competitive the investment I had secured needed to be 50% larger then what I got. My order is not scheduled to arrive until late July or early August and that is only 2-3 months from when the ASIC product would come out.

With all things staying even that is like $100 a month per single without any kind of power costs taken into account. So while I guess you would maybe pay off half of the single if you did nothing but sell the coins to pay yourself back, you would still be $300 per single short of replacing them with the ASIC product.

Of course that is also if they ship in October, the price and difficulty stay the same, and there is a reasonable turn around time from when you order and turn off the singles and ship them to BFL before you get your replacement hardware. It would be pretty horrible if you order, and then turn off the singles/mini rigs you have to only wait 2 months or more to get the new ASIC.

I think if you could secure your order with a credit card they would ship you the entire shipment of ASIC products and once you get them you could send back the singles/rigs for a refund to the card. Maybe I missed it but it seems this trade in policy seems more clunky then it should be.

I had a similar problem and they advised me to email their support team or jump into IRC to let them know.

An example of a pool that can be "hopped" is deepbit.

I would assume with the glbse purchase the owner can point their equipment at say a 110% pool or Max and make their cut while paying the share holders a flat payout based on PPS. While someone who buys from GPUMax can point their cannon at a hopper pool and try and beat the odds.

Thanks, but I didn't get responses from some PMs I sent today so I decided to send it directly to MTGOX thinking it would go through since I am fully verified with Dwolla. Apparently there is still a delay to MTGOX and they won't let you cancel the transaction through Dwolla.

Looking for $1600 in MTGOX USD/BTC. I have Dwolla.

I have returned or exchanged every one of the cards with very low ASIC quality. I have had nothing but problems with high temps and crashes on ones that are in the 60-70% range. I of course first contact the mfg and give them the temps and numbers I am seeing and they give me the okay to return them to the store. Also I found buying the overclocked editions usually resulted in higher ASIC quality and lower thermals. I am not sure if they are just binned that way or what, but my last batch of basic HIS cards were all returned because they were complete crap for thermals and ASICs. When I say crap, I mean 65C idle 85C playing Diablo 3.

I started purchasing 5XXX series cards from places like [H] where I thought the cards would be more reliable. I have lost a 5850, 2x 5970s and a 5870 before they returned half their purchase price.

I will take cheap 7970s with warranties for now. I think if you got in with new 5XXX series cards that still have warranty options they are better, but I can't justify the risk anymore.

So I did some basic math at 11 cents per KW. With all the component costs static and the only difference being your 5 cards versus 4 cards at different clocks.

I have 1150w producing 2600 hash to your 865 watts and 2825 hash. That is with 4 and 5 cards respectively.

When you add in the extra cost of the 5th card you will generate 2% more money in the same 8 month period of time if you sell your cards for the same per card amount as the 4 card user.

That is based on someone buying 7970s about a month or so ago and mining until the reward halfs.

That is if I did my math correct.

If the difficulty stays the same and the price stays the same after the reward halfs you would be making about $1.10 more per day per rig than the person with the stock voltage 1100mhz miner.

Thanks for that. It seems like the Gigabyte cards are the ones that can get lowered in voltage the most. My HIS cards take a total shit with anything less than 1.1. You cards and another posters are both getting great voltage numbers and both are running GB cards. I have 36 7970s now and none of them are Gigabyte.

I have 24 XFX Black Editions and 12 HIS. I am not super happy with either's performance.

Edit: Any plans to release your custom monitor code?

Can you link to the model cards you are using?

I have been using XFX Blacks and bought several of the HIS when they were on sale on Newegg Business. I have not been able to get them stable at the voltages you are setting with yours. Another poster was able to run his Gigabyte cards with the triple fan setup at .88V. So before I order more cards I like to see the other options.

I did a 30 day loan and it was paid promptly. Wish there was more capacity!

Nice work.

Flashed one of mine and also getting 857, but my temps are 49C.

If it still is under warranty, I would contact the maker to see what they suggest. Most of the time when I report temps like that they RMA the card for me.

Can you confirm is this is the driver file?

Windows? Driver version? Card version?

Nice photos. When you can, would you mind going over what you used to change the mem clocks?

I already told you what I was looking for. Model, maybe the specific tools used to measure the outputs? Pictures? What tools used to set the speeds? How long of a mine to determine stability?

Why are you being so hostel? I own 20 7970s. I have 12 more on the way and I will let you know what I find with them. Not one of them has been able to replicate that posts findings for long term stability mining purposes. However, all of my cards are XFX Reference Design Blacks. What can possibly get hurt by sharing more information?
