Hey Lickman, Post your clocks and your config file and we might be able to help you out. You will find that Scrypt is a very different beast than Bitcoin and that you need to retweak everything separately to get the best out of it. I have heard that for the 79xx cards the sweet spot is something like Engine clock = 0.7 x Memory Clock. You also need to up the intensity a lot compared to Bitcoin, maybe start around I = 13 and tweak your clocks, then push intensity up to the limit of your rigs stability. Check around the forums and see what settings other people are using.
Here are my clock settings under MSI afterburner: 7970 Radeon Core mV - 1169 Power limit - +20 Core Mhz - 1150 Memory - 1643 GUI Miner scrypt alpha Thread concurency - 21312 Vectors - 1 GPU threads - 1 Worksize - 256 Intensity - 13 Use stratum - yes net Khash's 545-565 ----------------------------- I aiming to get this up around 700 or 800 Khash's range, is there something I need to add to a configuration file somewhere, or an extra flag value I need?

Thanks for the replies. I have got things running a little better thanks to the 7970 tip focusing in on the relationship between the GPU and the Memory.. Thanks tonyk2005. That tip alone (7970 GPU = 0.7 x MEM speed) alone gained me an easy 100 + Khash, bouncing between 550 and 600
I'm inspired now, really hoping to squeeze another 100-150 over the 5 cards I'm playing with.
There's a good chance I've missed something obvious to some of you experienced guys, so I'd like to post the Gui value log from litecoin gui miner and Afterburner Msi. Anyone know if and where those files are available?

Hello all.
Anyone able to say what 1600 MHash will net in 24 hours these days?
I went from over .1 BTC to around .025 in just a couple weeks, and that just seems really wrong.
I've been told by a couple members this drop in BTC production is probably because of the ASIC machines integration with the pool, but that doesn't make sense to me. In other words, if the extra GHashes find more blocks, faster, than the comparatively lower Ghash of any GPU miners producing, so what? Wouldn't the Ghash from the GPU, although being spread out over more blocks, produce the same net payout over more, but faster blocks, due to the help of the ASIC machines?
If what I was experiencing was just a hiccup, I'd love to fire up the cards again, and of course always on the look out for a new ASIC machine.

Hello all,
I just started mining Litecoin at burnside's coming from bitcoin. I've been successfully linked in for the past 3 days, so that is good.
What is troubling is the hashrate I'm getting off my hardware, which is as follows:
(Guiminer Litecoin ed.) 7970 - 450 Mhash 5970 - 390 Mhash per core Amd Scrapper on die mini gpu 30 Mhash Nvidia 560 Ti OC - not running yet
Now compared to mining bitcoin, this is crap, since before I could get over 1600MHZ consistently with this setup. I've got everything overclocked and lowdown is that the 7970 is only getting 450 Mhash! Something seems definitly wrong with this speed. The 5970 is getting about 390 Mhash per core, which I think is respectable. Can anyone offer some insight here as to how to get more appropriate scores for my hardware?
Cheers,
Lickman

Thanks for the replies here. I have been looking into that, but we'll see if there's any bounce back to the rate/day before going down that road.
From most of what Ive seen here on Increased hash rate, which was 16000 GHASh yesterday, the payouts, although lower because of the smaller individual share, should balance due to higher frequency, which does not seem to be the case.
Anyone able to explain this?

Hi there,
In May I was getting over .1 BTC per day on a little more than 1600 Mhash, now a month later its almost as low as .025, a quarter of what it was.
What is going on ? What should 1600 Mhash be producing per day, approximately?
any ideas??

Ok I have setup a couple of workers (that was what I had done wrong). Now my two 460 GTX's are moving at a combined rate of 121 hash. I have read that Ati does a better job for reasons I don't completely understand.
Now I'm trying to see the balance, and here GUIminer displays another error
"Bad response from server"... Anyone able to share some knowledge so I can go through this obstacle?

Hi Folks,
Nice to meet you all.. Very exciting stuff going on here.
I have set up GUIminer and am trying to login with username and password with my account at http//mining.bitcoin.cz but there appears to be an error with doing that.
Anyone shed some light on getting GUIminer logged in?
