PSA : Final Litecoin LTC GPU miner released !!!

[bulanula]

This is the final full version that includes the source code and not the limited "demo" version. This is the real thing. People need to switch to LTC right now because it is much more profitable than BTC ( especially for Nvidia cards ).

Get it here while it is hot : http://wiki.solidcoin.info/wiki/Reaper

Everybody needs to switch from BTC to LTC right now because it is much more profitable.

Nobody is mining BTC anymore

Please post what card you used and how you got it working and what hashrate you get. I am interested in what you get using 5870s !

Thank you very much !

Been out for four days

Profitability is only in relation to the difficulty, which is going up

AFAIK the final version 13.3 is just out today.

It is profitable to mine LTC right now rather than BTC for some cards.

Difficulty is still pretty low so get in while you can

You can listen to Bula or you can do your own maths and figure it out for yourself. =P

I updated the Wiki page to include GPU/CPU Sections, and overall cleaned out all the old listings. Please add your GPU's here:

https://github.com/coblee/litecoin/wiki/Mining-hardware-comparison

I may have added a few of yours already (I think I copied one 6950 from here). If you see it don't list it down twice!

When using on PC with nvidia 550Ti or 540M, or AMD 7950, computer seem to be unstable and crash reboot when quit reaper either clean shutdown q enter or ctrl c

Is it just me or does this not seem profitable for 5870 series cards due to slow memory I/O

300 khash/s vs 440 mhash/s

Hashrate is irrelevant since you are mining with two different algorithms on Bitcoin and Litecoin.

That is correct but I was referring to the profitability that each hashrate can bring.

Just did some calculations right now.

400 khash/s for one 5870 mining LTC scrypt : 0.3 BTC / 24 hours

440 mhash/s for one 5870 mining BTC SHA256 : 0.3 BTC / 24 hours

SO what to do now ? LTC or BTC ?

Can someone publish some numbers for Nvidia please (especially interested in seeing GTX580 numbers)?

Sooo depressing mining at kh/s instead of Mh/s though...

A 580 will probably get about 160kh/s

Mining LTC means you will make roughly .03-.04USD a day more then BTC.

That presumably isn't counting all the altcoins you can get alongside bitcoins by merged mining though, right?

And also pretty much zero liquidity with litecoin as compared to BTC...

[Nim]

My numbers with current difficulties:

245Mh/s => 0.164 BTC per day

vs

265kh/s => 182 LTC per day => 0.001075 LTC per BTC (bid price right NOW) => 0.196 BTC per day => 19% more

Of course there would be a percent or two of friction in the exchange but the difference is still quite a bit. Obviously at my miniscule mining numbers, it doesn't make much difference but I see no reason it wouldn't scale.

I think GPU mining might end up helping Litecoin rather than hurting it because it will act as a stabilizing force as miners switch back and forth between LTC and BTC depending on which is currently the most profitable.
