Haha everyone will tell you their 0.20BTC on what they think is happening with the market. Should you listen to them? No way!

Should you read lots about investing, markets, trends, etc... absolutely! That includes outside of bitcoin too. Don't line up with the sheeple!

Make sure in your ATI CCC panel that "Overdrive" is disabled.

Then choose to either use a vendors program to modify the fan speed, or, do it with your miner.

If you want cgminer to force a fan speed other than its default 85% speed, you need to edit your config file or add an argument for "gpu-fan"

I use the config file and I have four GPU's so my config file looks like this:


Where the first 3 GPU are watercooled so fan speed is no matter, and the 4th is set to 100% speed.

My config file does not list "auto-gpu" or "auto-fan" nor do I use those arguments.

If it's not working then you probably have a 3rd party or vendor program that's actively hogging the state of the fan speed.

Ughh this guy has necro'd so many threads with this question I've lost count.

Nah I made it for you at 3am in the morning because I can't sleeeeeep.

Any ASIC device should be able to mine any of the SHA-256 based coins. When you tell your mining software to mine a SHA-256 altcoin that is not bitcoin, all you are doing is giving it the different network address and login details of your solo mining software OR those for your pool. The hardware does EXACTLY THE SAME COMPUTATIONS.

As evidenced in practice by the guys who clearly are mining with ASICs on the d7 PPC pool...

It could be a software problem: Can you mine in a pool with both cards correctly?

It could be a hardware problem:

- Your motherboard may not be able to supply enough power to both PCI-e slots (each rated 75w max) to each card --> get a better motherboard or buy risers with molex connectors spliced on
:and/or:
- Your powersupply is not sufficient. Test with another powersupply to confirm.


In terms of process of elimination I would first look at if pool mining works, then look at the PSU, and then by process of elimination if it still isn't working I would conclude motherboard limitation.

I have done an amazing job annotating this example screenshot of BTC/USD. It is aimed at a total noob.

Apologies if I have used incorrect terminology, I have no qualifications and little experience with investing

In my case I wanted to replace my watercooled 5970 with something that uses far less power, my last power bill was over $725/qtr although the heat in winter (now) is nice. I realise I might not ever make my money back but I still enjoy mining and the novelty factor of the devices and hardware amuses me. In the future I will probably look at investing in more profitable options though. The fact that you can order the USB's and get them at your doorstep within days is another plus.

Because I only mine SHA-256 altcoins the discussions that can be had about litecoin and other scrypt based coins on GPU is not of significance to me. I loathe the idea of raping the memory subsystem of a graphics card when the SHA-256 coins profitability is almost that of litecoins on a weekly averaged basis.

The heat issues of the USB miners seems trivial to me and I intend to investigate it further when mine arrive. I have dozens of various heatsinks and fans around the place ready to be put to use for silly business like this. I also have access to a FLIR thermal imaging camera or two with quantitative readouts, it depends on if I can book them in the near future at work.

OP Please have a look at this website I think you will find it very informative.

http://bfl.ptz.ro/

The question I have on my mind is about whether this is all for charity, for the 'greatness' and 'potential' of bitcoin, OR do you intend to charge users on a case-by-case basis for your services?

The first half of the OP seems like a charity making a media announcement but the second half sounds like you are here to turn a quick buck. If you intend on making money around here from users I hope you have some way to verify or prove you are indeed qualified (for their sake).

It's fairly well known that most lawyers (and various other professionals) will never give their opinion or advice unless they are in a formal agreement with a client because of the obvious liability issues that could arise.

You could get out of newbie jail by making 5 posts here and being online for 4+ hours, then investigate your options: https://bitcointalk.org/index.php?board=137.0

I think the mods can move posts like this to the appropriate subforum and you have rights to post in your own thread you created.

Unfortunately I do not have enough understanding of your code to validate it or comment, but looks interesting.

There used to be some Australian companies (probably just owned and operated by one person, mind you) who would take your BTC and pay you via BPAY, which for those unfamiliar it is electronic funds transfer usually for payment of bills for services like electricity, gas, insurance etc.

In all honesty it was good because:

- You could confirm their payment by contacting your service provider (bill issuer) or on their website
- I don't think they could do anything malicious with only the bill/payment reference number that you had to provide so that they could send the funds
- It was a 100% tax dodge  

Make sure you do a backup or don't delete the original wallet.dat or entire folder until the new one is up and running. As a matter of fact you should have several buckups in different physical locations at all times anyway.

Treat any backup with the same security you would with the actual wallet.dat file.

Regardless of the reasons behind wanting them, DEMAND IS HIGH.

So yes a Aussie group buy is worth looking into. However I might suggest waiting until the 10th of this month for the expected ASICMiner new hardware announcement that will be made.

I would undertake this task of running a group buy myself however I just don't have time during business hours at the moment.

The fact that you have seemingly spent (how many thousands?) of $ or BTC on Avalon hardware but you can't answer your own question is highly concerning to me.

Why would you take such a huge investment risk diving into a area you seemingly don't know much about? 

The answer to your question can be googled in 30 seconds or less, why have you not done this before investing in this hardware? Likewise the tutorials and guides to setting up solo mining on either SHA-256 coins or scrypt coins are just a forum search / google search away... it would take you days to read them all.

Even without looking at it quantitatively or statistically, the short answer to your question is "it doesn't really matter" because your hashrate is so high you will still see returns in either case in a fairly small short frame (weeks-month).

No OP, you definitely DON'T want to solo mine if you are just running a couple of GPU's. You could mine for years and not find a block, and those power bills won't make it worth it.

If you are really interested in the idea of solo mining I would suggest you look at the altcoins that have much lower difficulties where you might be able to find blocks every few hours/days.

I will make the assumption you want to buy it pre-built because you don't have the knowledge/experience to do it yourself. Please disregard this post if you are in fact buying it to save yourself some time.

If you buy it pre-built are you really going to be to operate the hardware correctly and safely and optimise your hardware and software for the best mining performance. When I say optimise I mean in my opinion and experience most of the popular mining software comes essentially pre-optimised to a large extent for mining SHA-256 based coins (eg. Bitcoin), but scrypt mining (eg. Litecoins and the larger majority of the other altcoins) on the other hand requires far more tweaking and understanding of what you are doing. If you intend to use scrypt based mining then I find it VERY hard to believe you could optimise the miner's arguments/preferences whilst not knowing how to assemble what is essentially just a standard PC with a big PSU and a lot of graphics cards plugged in (you don't even need to google hardware compatibilities - people on this forum have already done that for you).

Are you going to be able to fix it when something stops working for one reason or another?

If my comments have raised your own doubts then I suggest you look at getting some pre-assembled ASIC hardware instead.

Sorry to go back to the OP, but why do you want to use the IGP in the first place as opposed to one of the cards?

In my experience cgminer can easily manage the primary display by just playing around with the intensity setting of the card to still allow for completely unhindered user experience with windows and media playback (ie. nil delay in rendering 2D and video which I assume is what you meant by "normal work").

Getting a perfect balance of intensity on the display device will probably take you <5 minutes of trail and error, which seems like HOURS less effort than what you've gone through to get the IGP+Cards working to you liking.

In fact, I believe the default settings of cgminer have the intensity set to not interfere with or slow the user interface.

Yeah. Because of my science background where 'delta' means 'difference between' I thought he was saying that his temps under load are 92 F more than ambient (it would have to have been F because if it was C no card could survive unless he lived in the arctic or something).

First I will say that I am a hyprocrite. Because I purchased two yesterday.  But I will also say you should not buy them unless you truely have an interest in the hardware ownership and/or coolness factor of 'having ASIC hardware'.

Why? Because calculations taking difficulty increase into account usually show that they will never make back their current cost.

If you wanted to use the money more wisely, or use the 'but BTC will rise in value and I'll be rich and it'll make ROI!!!!111' argument then you would still be better off buying and holding BTC.
