any body help me?
i using laptop. i set many line commond for cudaminer but dont working:

I wouldn't even bother trying to figure it out, to be honest. What is an 8400M going to get you in an ideal scenario, like 15 khash? It won't even come close to paying for the power, and to make it worse you're probably reducing the lifetime of a part that's already old and well used by now because it's in a laptop.
You are right!
ok thnaks broFYI for giggles, I got an 8400M GS going with these settings:
Code:
cudaminer.exe -i 0 -C 1 -H 2 -l L2x2
Also if you value your laptop you shouldn't use that GPU for mining. Search for "Nvidia G84/G86 Chips Defective" to see what I mean.has anyone noticed any performance changes running under linux vs windows?
i have so:550Ti
Linux kernel-3.11 x86_64 cudatoolkit-5.5 90-92 kH
Win7x64 72-76 kH
Odd I'm only getting 74 kHash/sec on a 550 Ti hosted on Linux. Then again it may be because I have it running attached to motherboard so old it has DDR2-667 and PCI-E 1.1...

hmm i guess i should try installing arch on a spare ssd
Thx for the info

Now to get to the point: Why is the GTX 275 that slow? Is it just because it only supports CUDA 1.3? Any tips on how I might get some more performance out of that old piece of crap?
Pretty much. Newer implementations of CUDA have various improvements to the architecture underlying it, which gives you different/better optimizations. That's why there's 4 different kernels packaged into cudaminer (legacy, Fermi, Kepler and Titan).
Oooh, L is for 'legacy' huh? I was wondering: "strange, Tesla doesn't start with an L."
I guess it really is too old.

please help me to set correctly my nvidia quadro 600. Auto setting F44x1 gives only about 30 khash/sec (

Here's something that baffles me:
I used to mine just with my GTX 660 Ti, then I remembered I still had a GTX 275 lying around, so I built that into my rig as a 2nd card to see what kind of performance I would get. In theory the GTX 275 actually isn't that bad despite its age, here are some numbers from Wikipedia, quickly edited together:
The GTX 275 has 41% of the compute power and 88% of the memory bandwidth of the 660 Ti.
I used to get around 200 khash/s with the 660 Ti even with version 2013-12-10 (now improved to ~280). So even judging from the old 200 khash/s, I should be getting at least 80 khash/s with the GTX 275, right? Nooope... 50 khash/s. 
I'm using K7x32 (thanks Christian!) for the 660 Ti and L60x3 for the GTX 275, which is the setting consistently picked by auto tuning. The other settings are "-C 0 -m 1 -H 2 -i 0", all tested and proven to deliver the best performance I can get on both cards.

Got an extra 20khash boost out of the crummy CPU. At least now this computer will be doing something useful.
That puts me over 300khash.
Is there a way to force Cudaminer to utilize more CPU so that I don't have to run Cudaminer and CPUminer at the same time?

Cudaminer doesn't actually use the CPU to "mine", just the sha256 stuff that can now also be done on the GPU itself. So if you want to mine with your CPU also, you need a separate miner.

As far as I know, no. Just run them both there's nothing wrong with that. December 20, 2013, 01:28:45 PM

Is there a readme for CPUminer somewhere for expressions?
I'm assuming you can create a .bat, right?
minerd -a scrypt -t 2 -D -o stratum+tcp://poolurl:port -O USERNAME.WORKERNAME.WORKERNAMEPASSWORD
-t is the amount of threads so adjust as you wish. Hopefully the rest is self explanatory, but if you get confused post again.

My overall CPU usage on all 4 cores only runs at 25% makes me wonder if I can also run a CPUminer to utilize the other 75%
Thoughts?
Thoughts?
Yes use 2-3 cores to CPU mine if you want a little extra. Just keep an eye on your temps.

Only question I have is how come when I use -H 1 my PC doesn't use 100% processor power across the 4 cores.

Could someone provide their Linux build on a 64 bit architecture, please?
I am unable to compile because of some missing dependencies, especially the CUDA toolkit that wants to install the hole xorg-x11 server on a headless machine.
Thanks!

Alright, I managed to tweak my settings and keep almost the same hash rate but below 100% TDP and well below on the temps too. I love this 660 ti so much haha
And anyone with Mine-Litecoin that hasn't heard, site is back up and running beautifully

Settings for GTX 660TI? Using K7x32 and only getting 295kh/s! My overclock is also bigger than yours

People's jaws are gonna drop on this post I think.
GTX 560 Ti - Steady 280khash/s with the new 12/18 cudaminer, been running solid now for 20hours.
-H 1 -i 0 -C 2 -l F14x16
Card is overclocked to 920 MHz core and 2200 MHz Memory. It's running hot at 88degrees, but I truthfully don't care if I melt this card.
