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 :-)

This PCI bandwidth limitation sounds like you might have larger gains if you OC the PCI-X bus itself (at least until Mr. B can get the GPU validation going 
My mobo can go 100 -> 120 with out even the slightest twitch.
I've just never messed with the setting for long as 90% of the OCing I've done is not bottle-necked at the PCI-X bus, lol. Nice to see an application for this!

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 ^^.

thx for the app Mr B.
nice work, smooth usage, never had any trouble.

Can anyone point me in the right direction to set up a GTX 280? Running the 2-04-2014 version it gets <14kh/s, which seems terribly low. I have afterburner installed and has messed around a bit, but nothing I have done seems to change anything. They auto tune in cudaminer chooses F46x1. I haven't played with much else: cudaminer.exe -H 1 -i 0 -l F46x1 -C 1 -o host:port -O username:pass
Don't go out of your way, I'm only messing with it because I'm bored shiatless atm. But if you can give me a hint or two, maybe my results will help someone else later.

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.

yes on linux. the bandwidth could still be a huge factor, as our systems are running pci express 3, and Christian is only on 2
ok so here is a little speed breakdown, fastest to slowest
PCI Express 3.0 x16
PCI Express 3.0 x8 === PCI Express 2.0 x16
PCI Express 2.0 x8
Relm9 you would be on the same speed a PCI Express 2.0 x16, so what speed PCI Express 2.0 are you running at Christian?

x8 2.0 here. i never had a reason to complain... Until now ;-:

cudaminer --algo=keccak -d gtx780 -L 16 -l K192x32 --benchmark
Just closes cudaminer on windows 7 x64.

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

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

Cudaminer with 780Ti reporting... 100 Mhash/s... could that be right?
When it first starts look for errors like out of memory or whatever. My hash rate goes way up when I use invalid parameters.
February 06, 2014, 12:45:45 AM
On my 12 HT core 4930 Corei7 (ivb) = ~1 Mhash/s

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).

a rapid test without the change in the code and K192x32
my gtx780ti get 55,3Mhash/sec (but it is running 70% TDP... wow it might save the planet too...)
How much does a cpu exactly ?
edit: autotune gives line in Giga Hash/s

I found that the result with the change in the code gives something 1 Mega more.
Beside that, the autotuning gave me this value: K1024x4 where I get 57,8MHash/s
Everything is overclocked... however it uses only 72% of the TDP and 60% of GPU usage.
I also tested the gtx 660oem, I obtained at K215x19 41,9MHash/s
(the card was also overclocked, however, the programm was running at vely low clock value (same for tdp and gpu usage)

yes on linux. the bandwidth could still be a huge factor, as our systems are running pci express 3, and Christian is only on 2
ok so here is a little speed breakdown, fastest to slowest
PCI Express 3.0 x16
PCI Express 3.0 x8 === PCI Express 2.0 x16
PCI Express 2.0 x8
Relm9 you would be on the same speed a PCI Express 2.0 x16, so what speed PCI Express 2.0 are you running at Christian?

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.

Hmm I have lost around 120kh/s per card on the new version, using 2x GTX770
Was previously ~360kh/s per card now down to like 240 each.
My settings:
cudaminer -r 10 -R 30 -T 30 -H 1 -i 0 -l K16x16 -C 0

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.)

2:30 am here so if you want anything testing please let me know relatively soon, current config is
cudaminer --algo=keccak -d gtx780 -L 16 -l K192x32 --benchmark
currently doing i believe it is 34Mhash's
still lower then bathrobes, even though im on PCI express 3.0 x16

Are you testing in Linux? Not sure if it'd make a difference but I'm in Windows right now
