Perhaps lowering Queue, Scan-time, Expiry parameters might be helpful. This is probably a hardware specific thing that your FPGA needs. I use the values 0 2 2 respectively for those parameters but I am not using your exact hardware. Might be worth looking into. Changing those parameters is critical for solomining many of the altcoins and even in some cases using pools.

Never tried that pool but I can suggest coinotron.com and multipool.in if you rage-quit.

Dummy plugs have no use as of the last few driver 1x. versions in windows. Not sure about other OS.

I enjoy my newbie sub-forum enslavement. I have a collar and these shiney shackles to prove it ^_^

I'll give you some advice without buying ^ his book.

I would not setup a large scale operation right now. Your lack of experience (you had to ask the question, after all) has already got you off to a bad start. Setting up a large scale mining operation will at least be a full time job for a few weeks/months.

You take on a huge financial risk and again this comes back to your experience. Have you ever run a company or a business or even something like a little ebay store? Mining coins is just as difficult to ensure you don't end up in the red or losing heaps of money on invested hardware because they turned out to be unsuitable / irrelevant with the ASIC revolution.

Oh yeah about that. Those ASICs. They are changing the entire coin mining game. Everything is in a state of flux right now. There is immeasurable demand for working ASIC hardware right now, and you'll see the inflated prices from various manufacturers to prove it.

I would definitely look elsewhere for the time being. You have just finished university... why not look at graduate positions and programs available from large companies? You'll get your foot in the door and be making real money faster than you will from starting from absolute scratch with coin mining.

Sorry for the overwhelming negativity of this post, but realistically you would have had to come to us and said "I've spend X months mining at home and now I want to take things full scale, with a substantial investment...." kind of post for us to encourage you to move forward with your idea.

This whole forum is a giant whish-wash of discussion about the quality of these companies. There are also other companies, like Avalon and all the avalon clone/knockoff companies, then there is ASICMiner with their blades and USB stick miners, along with newcomers like TerraHash who have taken preorders but revealed only a little about there hardware. Then there are at least 999999999 other companies with little to show and which are probably scams. I would suggest you look around this forum a bit more you'll probably find the need to make your website diminishes because of the huge quantity of information here.

More than he ever will make from mining with $2500 of BFL hardware.

You must have at least 5 posts AND have been logged in for at least 4 hours

- You'll eventually kill your fridge/freezers compressor because they are not designed for continous operation: which it will be if you put a heat emitting source inside of it
- You'll probably damage/kill the mining hardware because of condensation, it is NON-TRIVIAL to make it resistant to moisture or to remove the moisture sufficiently. (It can be done, for sure, but it's not worth your money or your time or the frustration if you fail)
- My understanding is that the clock speed of the ASIC chip in BFL hardware does NOT vary with temperature, so whoever told you that is probably lying. Similarly a GPU cooled by air running at 90 deg C runs no more MH/s than a GPU running chilled water at -20 deg C. (If you don't know what waterchilling is, it is sub-ambient watercooling, refer to a forum like XtremeSystems)

BFL will include adequate cooling. Your biggest problem with it, assuming they've done OK, is that you'll eventually have to clean dust out of it.

If your budget is so low then I'm sorry but you just wont be able to get in amongst the other miners because the demand is just so high for ASIC hardware right now. The best you can get for your money if you desperately want to say "I HAVE AN ASIC!" Is to buy a block erupter USB but as many people will point out you are very unlikely to ever make your money back from mining with it.

My suggestion would be to just buy $100 worth of BTC and hold onto it for a long time.

Overclocking CPU is irrelevant since your miner should not be maxxing any of your cores anyway. (Mine runs 0 to 5% at any time with four GPU's going).

- Your pool is not providing work fast enough. Try another pool or add backups
- Your GPU is quasi-crashing because of some kind of problem with its clockspeeds, power supply, heat, or it's damaged permanently
- Your computer has an extreme bandwidth limitation in the PCI-e port and/or subsystems that interconnect it to the rest of the computer. On cheap motherboards this is a common problem. On my PC my hashrate drops by 20% when one of my storage devices is transferring data. Even the network port when heavily in use slows my hashrate. It's because all of these devices share for resources on the motherboard (eg. chipset / southbridge bandwidth).

Wow I typed up a 2-page response to your post and then the stupid forum auto-logged me out and I lost everything. I will give a brief re-summary.

- I have a lot of experience with 5970's, the dual gpu card of the 5xxx series
- You can disable ULPS 'completely' by ticking the check box in trixx but then also running a batch file / program called ULPS_Configuration_Utility_v1.1.4 that you can download. You need to restart after toggling the state. When you are not overclocking and the card is stable you shouldn't have to go through the ULPS nightmare again.
- Booting into windows and getting folders crashing means you have either permanently damaged the card or you are running a unrealistic BIOS or you have a program forcing unrealistic clock speeds/voltages as soon as windows boots.
- When GPU-Z displays values like you copy-pasted on a dual gpu card it means that one of the cards has hard-locked and you must restart the computer to reset it.
- You should instead run the card at sub-stock speeds and test with GPU testing in a program called OCCT. Make sure you have error checking on, the card is installed as the primary display device, and you are running the test with highest shader setting and fullscreen (to get 2x100% utilization of the cores). Run it with increasing speeds/voltages until it crashes or gives errors. Never change speeds/voltages while the tests are running.
- TO test the PSU, run the OCCT CPU (>C<PU) test and keep an eye on the voltages it records. Then start your miner or any program that uses 2x100% load on the GPU cores(not a game...), like fullscreen FURMARK or something other than OCCT. Stop that program and then also end the CPU stress test and peruse the voltage plots it has saved. As to how much the voltages should vary when you amped up the graphics card then I would say never more than 2-3% in my opinion. For my system I can pull 700 watts in under 1 second from my Corsair 1000 watt PSU and the 12v rail voltage and all the others will not vary by more than 0.01 v, it all depends on the size and quality of the output rail capacitors in your powersupply.

Hi,

What mining software are you using?
What parameters (settings) are you using to run the mining software?
What clock speeds are your GPU core, and memory. Have you overclocked anything? Are you using the original BIOS or have you flashed it?
What is your exact card 69xx <-- fill in the rest?
Do the errors occur as soon as the mining program starts or after a few minutes?
Is your powersupply adequate to run the card? (Depends on the card, depends on the powersupply make/model/watts, it's age, the rest of your computer hardware it's running etc)

With more info we can probably help you. There is always a chance something is wrong with the card but usually its a silly overclock / BIOS / parameters.

Because the blockchain is like a public ledger anyone can view the BTC present at any address. Some have tens of thousands and their precise BTC values are similar. That possibly indicates they have the same owner. For example at one time I recall seeing a list with several addresses with values all ending in xxxxx.1337 BTC

Also you might want to have a look at http://www.reddit.com/r/Bitcoin/comments/ifl26/distribution_of_wealth_on_the_bitcoin_forum/

Of course a lot of people have lost a lot of money, and yes there will be millionaires. How do millionaires act? I have met of a handful in real life and they tend to be a little eccentric but they are likeable people. But there is no real way to tell online if someone is a BTC millionaire.

It's still worthwhile in some countries with cheap electricity rates or for those who have free power, but its true that they'd be better off mining altcoins at the moment.

Sadly this is one of those 'if you have to ask the question, you probably shouldn't do it' kind of things.

^ Good summary of the altcoins. Some have a foreseeable future and many don't. Definitely worth considering carefully before you spent a lot of time mining any of them. Each should have at least their own [ANN] thread in that forum subsection, and the larger ones even have dedicated websites.

Another concern regards the use of SHA-256 or scrypt algorithm for the mining (You can easily find out which coin uses what here: http://coinchoose.com/index.php) Those that use SHA-256 depend on high gpu core speeds and usually very low memory speeds. Eg overclocked cores and underclocked memory. This is great for cooling the card because you can just monitor the core temps with something like GPU-Z and put watercooling on the core(s) if you prefer a quieter miner. The problem with scrypt is that it requires a more 'normal' balance of GPU and memory speed performance... such as you would want for gaming except that the load on the hardware will be closer to 100% at all times while in a game it may not be. This results in huge heat generation in the RAM chips and memory VRM(s) of the card. Depending on the card this might be a problem at its default stock speeds or it might only become a problem when you start overclocking. My point being it is very easy to kill a card using scrypt mining if you have heatsink-less memory chips. For example on my 5750 if I run it with a modest overclock the RAM chips exceed 100 deg C. But you might not notice until you smell burning because they are not thermally monitored on most cards. (And yeah, I gave scrypt a miss after that and went back to mining SHA-256 on all my cards).

If I had a preorder with them I would probably play the waiting game. I'd rather commit to my original purchase and get at least some hardware eventually than try and sell the preorder place, then attempt to enter the ASIC market again (as there are not many promising opportunities right for orders <$1000, in my opinion.)

It will hurt for a while but as you do more regular exercise then after a workout you will get a pleasant-exhausted feeling in your muscles, I wouldn't call it 'pain'. If I run a few kilometers it feels really great stretching afterwards.

Yep, mt.gox is a fiat<->btc exchange (when you can deposite USD, that is). There are plenty of established altcoin exchanges. Btce and Vircurex have worked well for me before.
