LOL!!  Yeah, but that card is the so-called "7370" that uses the same GPU as the 7970's.  It should be worth 450-500 KH/s.  Very disappointing.  I've got 2 R9 280x's coming in the mail.  They should be worth 700+ each . . . now that's a minimum wage job. 

I'm mining using a (rather disappointing) Powercolor 7870 XT Myst Ed. (~320 KHs/s) and, when I can maintain a connection I'm getting about 7 coins/hour over at coin-base.org.

AARRGGHH!!!

When I began mining, there was no problem with staying connected to the coin-base SBC pool, but now I can't seem to stay connected.

Been dropping blocks 20 at a time with connection resets.

You need to download and install the CUDA development kit.  It contains the CUDA libraries the program needs.

Litecoin is a scrypt mining coin and is perfect for GPU mining.  There are several mining pools out there (I prefer pools over solo mining--lower risk but less reward.  I am currently mining with wemineltc.com

Litecoin is "ASIC proof," meaning that so far is has resisted being overwhelmed by these cheap ASIC mining processors.  It is perfect for the individual with a couple or even one high-end AMD video card.  (AMD is about 3 times as powerful in mining as NVidia).

PPC is popular, but it, like BTC is now being mined by folks with ASIC miners and GHz of power.

Good luck!!!

Thought I'd chime in with my recent experiences with XPM.  I'm running an AMD FX-8350 OC'd at about 4.4 GHz and running jhPrimeminer_RdBBeta4/0F_x64 in the Ypool.

Through a lot of research and Googling, I have finally figured out some of the switches in the command line.

Cutting to the chase, here is my current setting:  

From my reading, here are what the switches I have do:

-t - is used to set the number of threads running on your processor.  I am using 7 to reduce the load on my processor a little (just to make sure that my computer remains usable for GPU mining as well).  Some recommend using 2 threads/processor, but RdB said that he didn't believe it made that much difference, so I am only running a single thread/processor.

-m - this sets the "Primorial."  Depending on your processor, you may want to increase of decrease this value.  The default is set at 43, but better processors can be set higher.  I believe that 100 is the highest possible, but not recommended.  I find that the 61 RbD recommended in his thread to one miner, works great for me.

-target and -bttarget both have to do with the targeted chain length.  The default is 10, but rdebourbon suggested that it might be worth experimenting with using 9 in one of both of the settings.  At 9,9 I was getting a 6/7/8 ration of about 17/5.5/0.86, but I never saw a 9chain . . . which sucks, because 9's contribute so much more to your shares.

At 10, 10, I saw fewer over all chains, but I did score 4 9's in about 24 hours.  So the choice is more shorter chains and fewer long chains, or fewer over all and more of the higher numbers and shares.

My PPS with 10,10 was about 22-24000 {I believe that the jhPrimeminer that rdbbourbon built multiplies the PPS by 10 compared to other implementations, because a PPS of 2400 is about par with what I've seen for other processors.

When I went to 9,9 my PPS jumped to about 28-29000, and at the current 10,9 my PPS is running at ~23000/

I will give this run (10,9) a few hours to see what my 6/7/8/9 ratio is, but I suspect I will be returning to a 10.10 setting.

That's about it for now.

Edit:  I have been running at 10,9 for a while now.  My 6/7/8/9 per hour ratio is 10.49/4.19/1.05/.35.  Totals are 31/12/3/1

Note:  I am still allowing the program to auto-tune.

I'm leaning towards the newly reborn Stablecoin for the future, great design and intended to assist in maintaining anonymity.

Problem I'm having right now is maintaining a stable connection to the coin-base SBC pool.

I like Primecoin as well and am mining both of them and litecoin, but I am also looking closely at Mega and PPC.
