How does a quad 280x mining rig for oh, roughly $1500 sound? Is that a worthwhile investment?

Is it possible to calculate the LTC difficulty rise? Maybe someone knows of a calculator for it, or is it something like this...

Difficulty increases every 3 days, at roughly +300 per rise. Would that be a good rough estimate at all?

So many questions biggrin.gif

No, but what you mentioned seems about right. I'm not sure what's best to mine, but if there are more profitable coins I'd go for those and maybe put those into LTC as speculation.

 

I'm not sure how exchanges work exactly, but I plan to mine quite a few different coins and leave offers open so that when the price spikes (which happens a lot) then they sell, and that way I hope to keep profits above $100/day (on 6x290s with a theoretical 5MH/s rate).

(Of course, then you can easily get an R8 in a couple years of residency without concern.)

I go to an in state medical school with only $8000 tuition and have $0 undergraduate debt. I do take out loans but in my state loan forgiveness is given to practically everyone because the whole state of NM is considered a medically underserved area (except 1 county). I'll be graduating with ~$100,000 in debt and most hospital sign on bonuses are right around that (Hell an ER doc I know got a 400K sign on bonus with a hospital here). It shouldn't take me more than 5 years to pay off the loans.

Very nice... hopefully, by the time you're graduating the government won't have taken over healthcare completely - or you'll probably see those bonuses shrink dramatically (although who knows... maybe we'll just shoot for $50T in debt and you'll get a $500K bonus). rolleyes.gif

By then my practice will accept all forms of cryptocurrency! lachen.gif

It also doesn't hurt to have a GF who does quite well herself

Nothing else should be required - it should detect your GPUs right off.

Are you getting weird errors reported back or something?

For example my batch file for one of my 7970s:
cgminer --scrypt -o stratum+tcp://ltc.give-me-coins.com:3333 -u digicidal.2 -p y -I 13 -g 2 -w 256 --shaders 2048

That's it... no extra stuff, one line in a txt file changed to .bat and then double click on that. biggrin.gif Obviously you would have more shaders on your 290x so edit that part accordingly.

Once that is working to your satisfaction - then you can add the two lines for the SDK calls at the top or you can just make a second batch file for them (they only need to be called ONCE - regardless of the number of CGMiner starts/restarts AFAIK).

EDIT:
These are the two lines for the APP SDK (if you didn't know already):
GPU_USE_SYNC_OBJECTS=1
GPU_MAX_ALLOC_PERCENT=100

As stated, you can put them above your cgminer call in the batch file - or you can make a second one and just run it at the start of each reboot (of the machine) - the setting should hold even if you restart cgminer.

when I double click on the bat file I created it disappears right away.

That's a sign that you typed something wrong in the .bat file. For instance when I accidentally put cgminer in a bat file for cudaminer it would do the same thing. For the longest time I was putting cgiminer for some reason not cgminer. That threw me for a loop.

this is my bat file....

cgminer.exe --scrypt -o stratum+tcp://pool.d2.cc:3333 -u crrafferty.1 -p x -I 13 -g 2 -w 256

hmmm looks good. Try without the .exe (shouldn't matter though) and you do have the .bat file in the same folder as cgminer correct?

Have you given GUIminer a shot?

I'm getting so irritated right now. I can not get BFminer nor CGminer to work. No matter what guide I follow. I have removed "-" from the scrypt and put it back to 2, I have capitalized and uncapitalized everything, I've added and removed the .exe. I have no damn clue why this wont work. I'm on windows 8.1 if that matters. I'm also using 3.8.4 cgminer is it broken?

That's your problem! GPU mining is not supported in 3.8.4. Use 3.7.2
