Hey OP, the info in your OP post seems to be from the Bitcoin wiki's Litecoin page. A Bitcoin dumbass
developer named Luke Jr wrote that page, and it's written in a way that is supposed to make Litecoin sound bad, or less important than it is.
The Litecoin wiki's article comparing Bitcoin and Litecoin
is updated and isn't full of the FUD Luke wrote on the Bitcoin page (check out the Wikipedia talk page for Litecoin
for a good laugh). Anyway, the point is that you should probably update the OP post, if you can, with some of the information from that litecoin.info page (direct copypaste would contain more info than this threads needs).
Also, I just noticed this part: "When mining Litecoins, you use a lot of your graphics card's memory. This is why a high overclock on your MEMORY is essential to getting higher k/hash per second. However, you don't want the biggest overclock you can get on your memory, you want it in proportion to your core clock. I will go into that later." This is completely incorrect. Especially with 7950s, you want to keep the memory clock stock, and increase the core clock as high as possible while undervolting as much as you can. A classic example is the Gigabyte 7950s which can flash to the F43 firmware. They drop down to 1.09v, Boost breaks (awesome), and with 1150 core it's hashing at over 700kH/s. I should add that the situation is even worse with 7970s. They usually need to have extreme memory overclocking with core clock underclocking (some people are having better luck with non-reference 7970s).
Edit #2: Showing how it works:
GPU0 and GPU1 are running 1140 core clocks, while GPU2 is clearly 1150.
PS: If anyone needs an invite to the LiteGuardian pool (the one in my screen shot), I have a few left. They have a 600LTC contest going until the end of the month. One entry per day of mining.Edited by minaul - 9/25/13 at 10:53pm
