LiteCoin Mining

That being said, you gotta pay play. If you wanna make real money, you gotta start mining at a couple MH/s, and be able to pony up the costs up front.

My friend got an asic miner, but got rid of it at a loss because it wasn't making much money. If you want to mine, consider the payoff time, and adjust for the fact that the market isn't stable.

If you aren't mining at this point, starting now is purely speculative. With BTC hovering around $850 at the moment. You can currently make about $12-18 a day with a couple video cards... It's going to take a while to break even, and even longer to turn a make decent money.

And I'm not really tech savy either it just struck my curiosity after a couple YouTube videos. I wont start, it just seems really interesting.

Indeed. I didn't like paying for four video cards this past weekend, but I'm hoping that the cash I can earn can get me a second rig and/or be my gas money

Good news!

Tiger direct accepts bitcoin as payment!

there goes my BTC... lol

How do you setup gpu minning? everytime I try to set it up for doge coin it dosnt work.

And does anyone know whats going on with cryptovally cant log in.

Nvidia or AMD?

If AMD, did you install the AMD SDK?

Amd, maybe thats it

I just can't seem to get my cards running properly... It's been three days of tweaking settings and changing drivers and I still can't get both cards to hash at 700-750 at the same time.

So, at first, both cards would get to 750ish and then one card would begin drop off. It would keep dropping until it hit 200-300, about 8-10 minutes later.

So I did a ton of Google searching and tried a million things but nothing really worked.

Eventually I updated to the new beta CCC (14.1?) and now my issue is that when I start it with my bat file, one gpu hashes at 750 and the other hashes at 250-300. The load is maxed out, and it's running the exact same settings as the other card obviously, but it just refuses to work properly.

The cards are MSI Twin Frozr III 7970s. I have a suspicion that the card is throttling due to heat, and I've bought some risers to see if cooling the cards down will help but it starts hashing cold at 250 and doesn't go up from there, so I don't think that's it.

Go to the CGminer folder and delete the .bin files, should say scrypt###tahiti###.bin or something similar, but it'll have the cards core on the title.

I deleted them and ran CGMiner again but it's doing the same thing...

try the cards at stock settings, maybe the second card doesn't like the overclock.

Stock Clock with a unmodified .bat is getting me 425KH/s on GPU0 and 250 KH/s on GPU1

Stock Clock on a .bat with "-I 13 -g 2 -w 256 --thread-concurrency 8192" (which is what I usually use) is getting 510KH/s on GPU0 and 280KH/s on GPU1.

Same deal, GPU1 is always slower than GPU0.

Temps are fine, GPU1 is 78C and GPU0 is 72C. VRM Temps are 90C and 83C, respectively.

I tried swapping cards, and the card in GPU1's bank is always the slow one. So maybe there's something wrong with the board? I have a powered 1x riser on the way, so I can see if its the 3.0x16 slot acting up or something to that effect...

It cant be the card though because it happens to either of them.

I have also noticed that the slow card is has a jumpy VDDC Current, whereas the other one has a steady one. It jumps 20A from 100A to 120A constantly, which certainly seems like an issue.

That would point towards a PSU issue, but I am running two 600w PSUs and it doesn't matter which PSU the card is connected to, it's always the card in the GPU1 bank that has the Voltage fluctuation.

Here's the GPU-Z shot of it now:



Here's the GPU-Z shot of it when it was doing the "Start at 750KH/s and ramps down to 200KH/s" thing:



That being said, look at how high the VRM Temp is. It was likely throttling at that point and that explains the jumpy characteristics of load, voltage, etc.

However that doesn't explain why it's jumpy now...

Nobody said it was gonna be easy...
