Title: NVS 4200M benchmarks?
Post by: chucks on May 25, 2011, 01:43:33 AM
Probably not on most people's radars, but is 10M hash/s respectable for a modern laptop graphics card? It's not the fastest kicker in the bunch, even as a laptop chip, I realize, but I'm still a bit taken aback by the magnitude of difference between it and other benchmarks. Is this the limit of the card or do I need some tweaking with my mining program?

NVS 4200M, 1GB dedicated, 48 CUDA cores, 810Mhz processor clock, 1620 Mhz clock driver 275.27

-other specs- Core i7 2820 Quad mobile 2.3ghz, 8GB ram

running rpcminer-cuda -gpu -aggression=8-gpugrid=256 -gputhreads=512, but running with default or just about any other aggression yields the same results or slightly lower.

Thoughts for bumping up my hash/s? Or should I just be content with what I have?

you're probably going to get more hashes from your CPU, using ufasoft's miner.

my $100 desktop card gets 230mh/s

the problem that you are seeing with the low numbers is
  • nvidia cards are much slower (https://en.bitcoin.it/wiki/Why_a_GPU_mines_faster_than_a_CPU#Why_are_AMD_GPUs_faster_than_Nvidia_GPUs?)
  • it's a laptop card, they are much, much weaker than their desktop cousins

Honestly, if you're doing bitcoin for fun, it's a  "meh" number, if you're serious it's a "give up" number, as the other dude said, you may get more for just your CPU.

Yeah, that's kind of what I figured. I tried the 4-way and got about 5000 khash/s, couldn't get ufasoft's miner to run. Well I'll enjoy the centi-bit coins I've made so far. As more people figure out about them and demand increases along with mining difficulty, who knows, it might be worth a shiny quarter someday.

Code:
bitcoin-miner.exe -a 5 -o http://mining.bitcoin.cz:8332/ -u USERNAME.MINERNAME -p PASSWORD -g no


this is a working pure CPU batch script (aka a blah.bat text file)for the SSE2 miner, if you're at slush, just change the username.minername and password to your own, deepbit, you're on your own i don't use him.

(-a flag.. i think that's for GPU stuff if you have that on, idk, i haven't fooled with it)
