Thanks!

Had a similar issue myself when getting started with gpu mining on my NVidia GT555M, had to bring down the GPU thread concurrency down from 6144 down to 2048 initially to get it hashing properly and then steadily got up to 4096 where its at now, though the stale share count is pretty high on gpu mining (between 40-50%)..

This is apparently linked to the number of shaders and the thread queue depth for each shader - the shader count is woefully low on NVidia GPUs - mine is 192. Wondering if the magic number is 192 shaders multiplied by sharethreads 18 = 3456? Will have a stab at this to see if it helps..

Close to 1.5 million  shares submitted over 6 hours without yielding a block, something looks amiss..

I have been since I posted last.. Using reaper for GPU and LiteCoin-qt (minerd) from gui for cpu mining, yields between 12-15 KH/s..

I also tweaked the threads_per_gpu from 1 to 2, yields a higher hash rate - between 22-25KH/s now (using reaper). So getting around 35-40 KH/s now - not bad for a laptop!

Just kept experimenting with the settings and the below appear to be working - a paltry 20KH/s seems to be the best the NVidia GPU can cough up consistently..

worksize 256
aggression 14
threads_per_gpu 1
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 4096

I'm getting around 16-18 KH/s using CPU mining, so only slightly better using GPU mining.. May have to switch to CPU mining if the stale count isn't low..

Hi all

Newbie LTC pool miner here just looking for some clarification..

Just trying out ltc mining on my Dell XPS 17 (Intel Core i7 2670QM 6gb 2.20GH with Nvidia GT555m 590MHz/3gb dedicated video ram) with reaper and this is the output which seems strange..

Any ideas what could be wrong?

Apologies, corrected now (and original post updated too, just in case..)
