Cryptocoin Mining?

Where can I buy these dummy plugs?

if i run 2 cards can i just hook up 2 monitors instead of dummy plugs and turn off the second monitor?

Yes.

The dummy plugs are easier just home made. http://www.overclock.net/folding-home-guides-tutorials/384733-30-second-dummy-plug.html

You can turn off but I don't think you can unplug. Yeah $1 gets you the resistors you need from Radio Shack.

 

[muskie32]

Ok, is there anywhere online I can buy the resistors ?

I have a lcd tv with a vga input i'm gonna use so it wont get unhooked

Even though phoenix-phatk has a higher hash rate it produces significant stale/invalid such that the result is little to no net gain. So, I've just returned to standard pobclm.

I switched back to pobclm, though for different reasons. It might just be me, but Phoenix has a lot of issues with disconnecting and not being able to reconnect unless I do it manually. Lost a good bit of time mining with that issue...

Question for everyone. How do I set up multiple GPUs to mine on a non-SLI/Crossfire motherboard? From my understanding, I hook up a 1x PCI-E extender/adapter and run my card off of that. I'll also need a dummy plug. What about drivers? I currently have my 5830 installed. Do I simply plug it in and start mining, or will I have to change/modify/install drivers for this setup?

This would be a much more cost effective route compared to using my spare 5770 in a new computer. My next problem is finding out where I could put my 5770 if I were to mine with it and the 5830 with a multi-GPU setup...

 

[muskie32]

Never mind, I just bought a crapload of these.

5870's back in stock now!

You can unplug. That's how I'm doing it. Share a monitor between two computers. Monitor needs to be plugged in when computer starts, then once you set everything up and get it running you can unplug it and set up the next computer.

As for running multiple GPUs, you might need to uninstall/reinstall drivers once you put in the second card. Then you just run a second instance of the miner and use device tags for both.

THANKS! I got 3.

THANKS! I got 3.

Glad to help! Still playing COD4?

I have not had time lately... I have been so busy setting up my folding farm, ect.

With Linux you don't need dummy plugs. Unlike NVidia drivers, ATI drivers expect an X display to be running on the card. That's pretty easy with a manual xorg.conf. I just tell it to pretend a CRT is hooked up, provide CRT timings and off it goes.

The beauty of this approach is then I can run all my miners from the command line, and keep tabs on them from my phone, any PC in the world, etc.

Next step: completely diskless operation, controlled from my router. No wallet.dat on any mining machines.

Been mining for about 1/2 day now, barely got 0.15 coins. It's going slower than expected for 190 Mhash/second.

Ouch... at that price on Newegg, it looks like you may be better off getting the 6990 .

I thought the 5970 was the king of bitcoin

 

[muskie32]

Yeah, I might have to pick one up...

The 5970 should be faster than a 6990 since a 5870 is faster than a 6970, but it's also $40 more expensive. Isn't the benefit of the 5000-series typically the fact that they're not only a little faster than the 6000-series, but also that they're cheaper? I mean... it's possible to get the ~$110 5830 up to hashing rates that are close to my $280 6950 (albeit I'm not using large overclocks).

 

[Auric]

5970 has 3200 stream processors vs 6990's 3072, however as with all such comparisons it depends upon overclocks and the later series would generally be superior due to smaller processes and other efficiencies. So, the advantage to the 5000 is that they had become cheap. The 5830 especially was something of a stinker for gaming, value-wise.

Would a dummy plug allow a Radeon mining in the background whilst Intel Graphics runs the display? BIOS allows Clarkdale GPU to always run however with display attached to it (and none to Radeon), Radeon device was not presented.

Some people have problems with phoenix giving a lot of stales, but we haven't had that trouble.

The problem is not with phoenix itself but phatk (phoenix with pobclm is fine). Also, stales designate those already processed elsewhere so it is just the invalid or errors which increase with phatk. Are you using 5000 series? Supposedly phoenix-phatk is more appropriate for those and the reason for the higher rate is maintaining efficiency with OpenCL 2.4 whereas pobclm suffers a decrease versus 2.1. However, 2.1 failed to present the 6000 series device.

What are the chances of the bottom falling out of this in the next 60 days I wonder. Doing some math it appears it this could possibly pay for a 6990.

I am wondering the same thing... Seeing that I just bought over $1000 in hardware

 

[Auric]

Consider what may be recovered by selling the device after a potential crash. Presumably, the 6990's value will be more affected by feature and performance comparisons to 7000 series and will hold up well for gaming in any case. Whereas 5000 series prices are inflated by mining so have the most to lose.

To me, it seems that it's really all about perceived worth. I'd say that BitCoins are going through a sort of "gold rush" in that people realize that with a relatively small investment, they might possibly make a decent amount of money. Although, from what I understand, it seems that the people who stand to make the most money are those who started at least a few months ago. The difficulty to process the hashes was lower and now after the article was published on BitCoins, they saw a huge increase in value of however many they had hoarded.

I'm still a bit way over BitCoins though. It seems the only people taking them seriously are the people trying to mine them as I've seen people selling goods with BitCoins as tender. If the difficulty level raises too high and people realize that it will take them way too much of a hardware investment to create a decent amount of money... will they just give up and the hardware craze die down? If that happens... who is actually going to accept BitCoins as tender?

People/Businesses need to be willing to accept these things for transactions for them to maintain a significant and non-overinflated worth.

I'm certainly no economist though and it's really only my thoughts on the matter. I'm not worried though... I've spent nothing on this excluding the electrical costs, but I doubt I'll notice the increase versus what I'll be paying with my air conditioning coming on as much as it has lately .

EDIT:

I'm actually tempted to try and sell my 5870 now if I can get a premium for it. Why worry about BitCoin mining when I can simply milk the fervor created by the mining itself. If the 7000-series is coming out soon, I could put the money toward that and just move my 6950 to my older machine (where the 5970 currently is).
