Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Anyone had a chance to test the new 337.50 drivers yet and see if there's any more performance out of em for mining? Guessing not since it's focused around DX, but one can always hope ^^
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Should I try to go back to the December version? Am I missing a prerequisite software to make this work with the latest version?
Maybe try running 4 individual cudaminer instances, each with individual -d flags from 0 to 3
You could also try passing the -m 1 flag to use a single memory block on each card.
I have no idea what is causing the cards to act so strangely.
Christian
Running T14x24 -m 1 flag, 1 GPU per instance works but with the pitiful hashrate of 17-20 kh/s.
I was getting 500 kh/s per Titan Gpu on the December cudaminer build.
Try going downwards from 24 till you find one that gives you good khash
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
For anyone with an 780 you could try this:
-L 128 -l K996x32 -H 1 -i 0 -C 1 -m 1
When it actually wants to work at max speed (starting the other client mining normal scrypt goes to max clock directly..) it sits at around 193mhash, card is at 1254mhz and default mem
-L 128 -l K996x32 -H 1 -i 0 -C 1 -m 1

Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Well, I'm having some issues with the scrypt windows binary...
I was happily mining at 716kh/s with my GTX 780 Windforce at 1267mhz core and I tried higher clocks and crashed.
Then I restarted and whenever I try to mine scrypt cudaminer won't make my card go past 953mhz (stock non-boost clocks?).
I have a custom bios now that removes boost and can mine other coins at 1329mhz core with 1100mv only but cudaminer is still pegged at 953mhz core.
Any ideas?
EDIT: I second the donation part...cudaminer is my favorite mining program now, the dev is really ahead of the game.

What's your config for that? I'm doing 660ish~ khash with my 780 gb wf, at 1254mhz :/ Do you have extremely high memclocks also or?
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Mate any idea why although
I have 2 GTX 780 (and two cuda miners) one shows 520 khps and the other 605? Can it be that the one that the monitor is plugged loses hash power because of it? Any idea what is going on?

I have 3 GTX 780Ti in one PC and two of them hash 10-20 kHash/s less than the fastest one. I attribute this to subtle differences in the PCI express connectivity.
But 100 kHash/s difference - ouch? played with the -H options yet?
Since they are the same I use the same configuration. My problem is that if i start either one alone. It does reach 605. If I start em together They both reach 605 but after 2-3 minutes the gpu clock drops and the Voltage and the hash with them (drops to 520). It s the upper card and the the monitor is plugged in meaning the pcie is the most powerful. Also this card appears to have more temp (85C) than the one that works with max hash (75C). (but probably due to the limited space that it has to breath).
EDIT: I also saw the 2 next answers. Thanks I ll try to play with the H (althouh I doubt i ll see any difference).
Have you tried undervolting your cards? With the new kernel I can undervolt massively and still have a high overclock (gtx 780). Currently running +310 on core which gives me 1254mhz, no memory oc, -50mv voltage which makes it 1.100 on load.
The lowered heat might make your cards stay at higher clocks more, you should also use afterburner to set the priority to the power target and not the temp target.

Have you guys monitored your cards in afterburner? The topmost cards might be throttling more than the bottom one, or just that they boost to different mhz. Custom bios with disabled boost is awesome in general.
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Does memory clock speed mater with this release ? I used to have mine under clocked by -500, i bumped it up to 0 and i gained 20khs.
It matters as much as you see there, very little. If you can run it at stock speeds with everything else the same it's of course free extra kh/s!
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
2 EVGA 780TI reference models with Skyn3t's bios. Per the other posts on this thread, iv tried many combos of C/H/m with T at 15x24 with no luck
-C 2 -H 1 -m 1 -l T15x24 runs at 20khs no matter what C/H/m is at
Best auto was T480x1 at 620khs
This new version doesn't work so well for me
-C 2 -H 1 -m 1 -l T15x24 runs at 20khs no matter what C/H/m is at
Best auto was T480x1 at 620khs
This new version doesn't work so well for me
Try progressively lowering it from x24 down to 20 and maybe even lower, see if you get the best results with x20 as some of us do
Thank you sir, very kind of you to help. T15x16 is running at 685khs!
cards running at 1188mhz, +105% Power Target, default voltage
So x16 gave you the best results? Or did you lower it to that at once instead of testing each 15x24-16? Would just like to know since it's so strange that people are getting extremely different results with the new kernel, with the old one it was very similar for everyone with the same settings if you had the same card and clockspeeds etc.

Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
For scrypt on GTX TITAN i think this is little bit better:
-d 0 -i 0 -C 2 -m 1 -H 1 -l T14x24 (605khash/s @ 928Mhz)
-d 0 -i 0 -C 2 -m 1 -H 1 -l T14x24 (605khash/s @ 928Mhz)
I'll have to try this out, I'm fairly sure that i'm getting very similar results with my config.
No matter what combination I use, the best I can get with T12x24 for my 780 is less than 1/3 of T12x20, ~170-185kh/s depending on settings.
Confirm some things for me:
- Make sure you are using the latest Nvidia Drivers, 332.21 for full Compute 5.5 support.
- Make sure you are unzipping a fresh copy of the files, not overwriting your current folder. I had a small issue where unpacking the latest releases and overwriting the files did not work correctly and cause funky hash rates. Not sure what went wrong but worth noting.
- Let us know the model of your card.
At the least we might be able to see if we can identify why this oddness is occurring and maybe make a separate recommendation for those that don't fall under the SMX x 24 bucket as intended. At worst it might be an unknown bug, but no telling until we run everything down.
Using 332.21:Yes. Win 8.1 x64 enterprise, 6gb ram, core i7 920 @ 4ghz
Unzipping to new folder: No difference. x86/x64 version, no difference
Card model: Gigabyte GTX 780 WF V2.0
Memory and GPU usage etcetc is the same, except that the power draw sits at around 45-50% instead of 85%+ with x20
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Looking quite awesome on the overclocking front too, currently seems to be stable at 1241mhz core and default mem, at 1.137V! Working my my down to see where it crashes haha. Now at ~660kh/s
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Also, what's up with people getting good results on their 780s using T/Z12x24 ? I get absolutely craptastic results with that!
That's like the 15x24 for some 780ti... yes me too I'd be curious to know... Is there different models (beside factory bios) ?This is due to the new Titan kernel that the Nvidia engineer submitted. S/He stated that the best config for it will be SMX x 24. This is why this setting is preferred.
780 -l T12x24
Titan -l T14x24
780Ti -l T15x24
Please try all -H -C and -m settings before you write the changes off. This is KEY with this release.
I went from
Code:
-l Z14x24 -H 1 -C 1 -m 2
over to Code:
-l T14x24 -H 1 -C 0 -m 0
(commit 114 to release) saw a very little kh/s change but found that the core could stably OC another 50MHz improving kh/s due to more OC head room No matter what combination I use, the best I can get with T12x24 for my 780 is less than 1/3 of T12x20, ~170-185kh/s depending on settings.
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Had to make the bat from scratch but I did see a 540 to 605 khps on my one GTX 780 and a 475 to 505 increase on the second. Again no idea why although same cards I get different khps... The second starts at 605 and drops to 505 as does the GPU core clock and the Voltage... (that was an issue in all cudaminers so no worries) if anyone can help? Btw no overclock.
What is the launch .bat command you're using for your 780s?
-i 0 -C 2 -H 1 -l T12x20
let me know if it works
Thx for the 12x20, was driving me nuts haha. Good speed increase, went from 500 kh to 600 kh with a 780 going from 12-18 to newest version. Seems to draw less power to boot! Time for some more overclockiiiiiiing
And x86 kernel works a lot better now than x64 for me, earlier it was a small difference favoring x64, 10-20kh+ difference now though between them.
Also, what's up with people getting good results on their 780s using T/Z12x24 ? I get absolutely craptastic results with that!
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Just remembered to try out the titan kernel.. good thing I did! Should have done that directly from the start haha, completely forgot. Runs about 10% faster with T12x32 compared to K12x32 on my 780, seems to draw less power too! Good stuff.
With the core at 1110, mem default, I'm at a nice even ~550khash/s now, doesn't need any overvolting for that.

Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Heh ok, can't mine with that overclock! Just got myself an GTX 780 which is running nicely at 1250mhz core and currently 1600mhz memory, skynet bios etcetc. Discovered what you did earlier, power draw is off the charts hahah. It wants more even at 125% TDP and that's when the 100% is boosted to 300W+ on this bios >_> Did give me 555k/hash+ though! xD Will have to tweak it a bit 
these mod bioses are made for overvolting - and the stock cooler can't take it. You need water cooling or extra strong aftermarket heat sinks + fans
Christian
Ah ye forgot to mention, it's an gigabyte WF, so the cooling isn't a problem. It's the power draw ^^ Way crazy. Gonna see if I can manage around 500khash/s at a less dangerous power draw

Thank you very much for this great tool. It is amazing and works almost perfect. Good job!
I am new to Mining and I am using it for DogeCoin Mining right now.
My system:
My best settings for CudaMiner are:
cudaminer.exe -i 0 -H 1 -C 2 -l F16x16 @ 282 khash/s
The only problem I got so far, is that '-i 1' causes the display driver to crash after 10 to 15 minutes.
I don't move the mouse and do not use the computer at all, but it still crashes.
If I use '-i 0' it works just fine and 5 hours or more is not a problem.
I also have a question:
Is is possible to tweak the display driver settings in order to improve the khash/s a little bit?
I use 'nVidia Inspector 1.9.7.2' and I could change nearly everything which is stored in the driver.
So are there any values I could try to change, which could boost the speed?
Thanks for creating CudaMiner, it is very interesting for me (I am still new to mining) and I want
to learn more about the whole process and the Crypto-Coins. =)

Hello there,
I have asus directcu ii gtx 580, and with "cudaminer.exe -i 0 -H 1 -C 2 -l F16x16" I am getting ~320KH/s. (Driver 331.82)
Wich card do you have? Be careful with temps, open your PC case for more airflow and use also and external big fan if it is necessary.
My GPU Cock is 925MHz Fan speed 78% and GPU Temperature is 68ºC (air temp is about 24ºC) and I am using MSi afterburner for controlling it.
Try 16x14 and see if you get a better hashrate, that's the best one so far for me at least with my 580.
For the record, 16x16 gives me around 80kH/s, and pretty much completely bogs down my windows. With x14 it's still usable even with -i 0
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Hi,
I've 4x nVidia Quadro K6000 cards and I am running the cudaMiner in autotune mode(if that's the mode in which it runs if no extra flags are specified).
One thing which I've noticed is that, one of the GPU out of 4 gives hash rate of 485kh/s while other 3 ranges from 280-370kh/s. I am getting a total avg of 1450 kh/s. Is this hash rate good at all? How to make the other 3 work on 485 kh/s as well?
Do anyone have any suggestion with manual config to get better result? UI response is of no use to me. Just suggest me the settings that would give maximum performance.
At last, I would like to thank OP for the cudaMiner. As far as I've read, it seems to be only one which makes nVidia cards any useful.
Regards.

Try adding -D to see which config it picks for the cards, and then applying the one that gives the highest hashrate to all of them. After that you can play around with -H 0/1/2. Otherwise from previous posts, you should try the -l config of (amount of smx units enabled on card)x32, which for k6000 should be -l T15x32, or maybe the kepler kernel with K15x32
-l T15x32 is the right start. Try T15x64 and see if it runs, but it will probably either crash or give you completely outlandish results. I've been unable to get that config running on a Tesla, though I may still poke at it a little more.
What you'll find, though, is that the Quadro is a terrible ROI for mining: -T15x32 will only use about 2GB of the DRAM on your card (and using more provides no additional benefits). The ratio of registers and FLOPS to DRAM on the Quadro isn't optimal for mining. Lower-end cards with less memory perform similarly (or better because they often run at a slightly higher clock rate). The 780 Ti, for example, has roughly the same compute horsepower but with only 3GB of DRAM, and it's a pretty speedy beast. Well, at least, in the range of nvidia cards.
I'm a little surprised you're not seeing about 40-50kh/s more on each of your cards, but that may be in the noise. Are you running one instance of CudaMiner across all four? You might try running four independent instances if your drivers handle it.
-Dave
Indeed, I was looking at resources and the RAM is so underutilized. Currently, fans are running at 40% speed. Occasionally rises up but pretty much stable near there. Yeah I am running just a single instance for all four.
So as per your suggestion, I should run 4 instance for one card each or 4 instance running on 4 cards each? I believe the later will fry the GPU...lol
I actually did get near about same boost. Previously was getting 1400'ish, now getting 1600'ish hashing rates. So ~200 kh/s increased breaking down to 50 kh/s per card. Before running with manual config, one card would do at much faster and others were doing pretty slow. Now, all are working at pretty much same pace.
One instance per card, specify which one it should run on with the -d operator, -d 0, -d 1 for the next cudaminer etc, I guess you'd have to make 4 folders for that too.
Also, do you have double precision disabled? Supposedly that gives a small boost
