Remember when I said that I could get ~600MH/s from the Radeon HD 7970 graphics cards (each) when mining for Bitcoins? The same 7970s are only able to calculate ~ 580KH/s (that’s kilo – meaning thousand hashes per second) for a total of ~1.5MH/s with all (3) cards running straight out.

This means that my GPUs which, since I am running the mining software on a PC with access to lots of RAM, gain new life as Litecoin mining rigs. This makes Litecoin mining much more difficult to parallelize using custom Application Specific Integrated Circuits (ASICs) or Field Programmable Gate Arrays (FPGAs) – which are in heavy use for Bitcoin mining now. The main difference between Litecoin and Bitcoin is that the hashing algorithm that you’re running is using Scrypt, which is a password-based key derivation function that is both computationally intensive, but also requires a healthy chunk of memory for each iteration (~128KB/iteration I believe). You still mine for the Litecoins using software such as CGMiner or the like using your GPUs. You have a virtual wallet – I am running the Litecoin-Qt version that they link to from the main Litecoin site. The process is very similar to Bitcoin mining.
I also have to point it at a Litecoin mining pool & port as well. I even use the same CGMiner software (version 3.7.2 as it’s the last version that supports GPU mining afaik) except I have to throw in the “-scrypt” parameter into the command-line when I fire up the software. Mining Litecoins is very similar to mining for Bitcoins. I have now switched my efforts over from mining Bitcoins to mining a similar virtual currency (arguably the next contender for the Bitcoin virtual currency top-spot) called a Litecoin.
Definitely not worth the power they’d draw, much less tying up two machines 24×7. Even at a valuation of $1000/BTC (current best-case-scenario) that only comes to about $1/day if I ran them all full-speed with fans-a-blazing. I ceased my GPU-based mining operations because even with my max mining rate with the three cards of ~ 1.5GH/s I am only able to mine about 0.001BTC/day. In my last post – Bitcoin Mining for Fun and (not much) Profit – I described my experiences with mining for Bitcoins using my (3) Radeon HD 7970 graphics cards.
