Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Is the new cudaminer available? I can't find it. Can someone share a link? I'm looking forward to see issue with pci risers x1 fixed, there is 20kh difference now between cards with same settings on x16 and x1
I was able to close the gap between x16 and 1x risers a little more by adjusting the batch size parameter. I found that, by choosing a smaller number than the default (1024), I could yield an additional 10.86 khash/s (+3.9% increase) from each card. Batch sizes that were a factor of the scrypt kernel thread count (768) seemed to achieve the highest speedup. I also ran tests with different launch configs but found little difference. YMMV
Here are some benchmarks I ran against a single EVGA Superclocked 750ti (factory default) on a 1x USB riser, 10 minute averages:
Code:
cudaminer --algo scrypt --benchmark -b $BATCH_SIZE --launch-config T10x24 --interactive 0 --texture-cache 1 --single-memory 1 --hash-parallel 2 --lookup-gap 1 --time-limit 600
Code:
