Hey folks, new miner here. I think I may be missing something in my configuration, as I'm not seeing any improvement with the new version of cudaMiner. I have a GTX 650 Ti BOOST, and am getting 187 Kh/s in both 2-2 and 2-4 using -l K4x32 -i 0 -H 1

Any ideas how I can squeeze a bit more out of this card? I'm running the default settings aside from running the fan at 70, and using MSI Afterburner to monitor the card. (I also use CUDAmanager in case something happens while I'm at work and things overheat, so the miner will be shut down.)

Yeah you are right, the first slot on my mobo is actually x16 but since I have two GPUs plugged in both slots are brought down to x8.

The new keccak code seems faster than a CPU I think.

Q9550 @3.4 Ghz (one core)
minerd-maxcoin --algo=keccak --benchmark
1151 khash/s.

i3-4130T @2.90GHz (one core)
minerd-maxcoin --algo=keccak --benchmark
599.59 khash/s.  (?? must be a fluke, lots of stuff running on this machine)

Celeron G1630 @ 2.80GHz (one core)
minerd-maxcoin --algo=keccak --benchmark
1020 khash/s

GTX560-448
cudaminer --algo=keccak -d 0 --benchmark -L16 -l F14x16
28468 Kh/s

I could not get cudaminer to run on my Quadro 295NVS. Not sure of the kernel parameters, it wouldn't start (not that I would want to run on this card anyway).

When it first starts look for errors like out of memory or whatever. My hash rate goes way up when I use invalid parameters.

Hey just going to throw this hack out there..

So on some of my machines, i probably have some HW issue , or overheating GPU .. or something (i can't be bothered to debug it..)

Sometimes I'd get into a infinite loop throwing errors.. it just never recovers.

I run supervisor on linux.. so I ended up just throwing an exit(0) in the errorcheck define:  



It seems to work.. every time it gets into the loop it'll just bail and supervisor restarts it, and for wahtever reason.. it works for a few hours.. then bails, but .. pretty much works 98% efficiency .. instead of being totally dead..

So just throwing this out there.. (yes i know this is a super lazy hack

I'm pretty sure you have to compile the latest code from github but Christian is still working on it.
Patience!

That's definitely not good, I have a lowly GTS 250 that will do about 40kh/s - 42kh/s on the 02-04-2014 version. That's on linux.

Autotune doesn't always pick the best config in my experience. e.g. when I autotune in non-interactive mode it picks F32x2 which drops the hashrate by 25% compared to either F16x4 or F15x4.

Try autotuning a few times with both -i 0 and -i 1 to see if it comes up with different choices that perform better - then you can manually tweak them from there. Other than kernel config (specific for your card) all the other options are the same as I fire it up with.

just played around a but with the miner in bench mode and the keccak algo on a NVIDIA 9800 GTX+ (with huge cooling rips), running on kubuntu 13.10.

When i fired the miner up i got 7961 khash/s, card went hot and it dropped to 621.49 khash/s and staying constantly there .

Will ply a it more tomorrow ^^.

Regards

Well once you have made changes or you have anything for me to properly test it I will let you know speeds as my system has 3 pci express 3 x16 slots, that all run at 3 together so I know my 780 is running max speed :-)
