Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
using -H 1 -i 0 -C 1 -D -l K14x16 with my 660ti. Its stable but the numbers dont look right and I still cant get my max overclock with the updated version of cudaminer. Would be nice if someone knew anything about that but apparently my buddy and I are the only ones with this issue.
Heres proof...

Your numbers are better than my 670, everything looks gravy to me so long as you are intending to push your card and sacrifice a little of it's lifespan.
Well thats what I was saying in a post earlier, since the update of 12/18 my gpu is now taking 103%+ power when it used to sit nicely at 95%
And if i up my voltages to where they normally are for stable gaming my core speed drops and so does my hashrate. So really right now these settings will instantly crash with any game or anything intense. Thats because my voltage is so low because I wanna keep my clock speed high for mining, even though it doesnt get nearly as high as it used to. As for lifespan, this is a MSI Power Edition card so I'm confident with the integrity however I don't understand how my power usage shot up like by a full 10% after 12/18 with the exact same settings I was using in 12/10.
EDIT: Also, what pool are you using because I was seeing the same results all yesterday. I was getting just chunks of stales in 5-10 when normally I'm at a 99% valid yesterday was like at 96%.
I'm assuming that changes made to the most recent version caused/allowed our cards to reach the full TDP that we have set. Before, I could set my power target to 140% and I would only use about 110% under 99% GPU load. Now that my hashrate has jumped up, so has the TDP usage and temps as well. I just sort of assumed that this was normal and that this build allowed our cards to run open throttle. I'd be pleasantly surprised if something could be changed that brought power consumption down while retaining the current performance.
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Did a bit more testing, had to back off my overclock TDP since temps were high, and I found that K14x16 seems to be the optimum config so far for my 670 FTWs. 630-640 kh/s range combined on my 2 cards.
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Peaked out at 643 KH/s!!!!!!
You and Dave are the freakin BOMB! Now I have to really fine tune my overclock since this actually uses 100% of my TDP, and temps are about 10 deg higher.
Previous version I was maxing out at 433 kh/s with 112x2. Now with this version, autotuning used K14x4 for GPU1 and K14x14 for GPU2. Set it to -l K14x14 for both and I'm getting 643 kh/s from 2 EVGA 670 FTWs!
-H 1 -i 0 -C 1 -m 1 -l K14x14

Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
any progress on the optimizations the cloud miner promised to send us?
wanted to ask about the same ...
keep checking his blog for updates.
He's published his secret sauce. So let's race to integrate it - hopefully we can compensate for the last 3 difficulty increases
Nice! Hope to see a new build soon
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Thank you !
Changed the config to cudaminer.exe -H 1 -i 0 -d 0,1 -l K112x2 -m 1 -C 1
and got

It looks good, but tried those flags back with k8x24 and got

Is that looking about right now?

Nice! My auto config settings usually get set to K14x16, but I've found that 112x2 gives me the best results. With that 680 your hash rates seem to be right on the mark. If your temperatures are cool enough, you could look into getting a few more kh/s with overclocking. I believe this applies to all kepler cards, but the most important thing to keep in mind is that your gpu clock will begin to gradually decrease after 65 degrees celsius.
From some overclocking testing I've done with my cards, I've seen that a 50mhz change = roughly 10 kh/s difference.
There is a pretty good overclocking guide that you can find here if you are feeling brave enough http://www.overclock.net/t/1265110/the-gtx-670-overclocking-master-guide
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Hi,
I have 2 680's, and letting Cudaminer automatically find the best settings for each card individually, it tells me 16x14 is ideal - which it appears to be. If I run one of my cards at that (either one), it'll give 200+ khs.
Trying to run both cards at the same time (with -H 2 -d 0,1 -l K16x14,K16x14) and the rate drops to around 0.7 khs - whats going on?
The only config I've found that gives anything other than either <1khs or a crash is 8x24, and that tops out at about 220khs with both cards running.
Any ideas how it can be improved?
Thank you

SLI needs to be disabled from everything I've experienced. Since our cards are similar, give this a shot: -H 1 -i 0 -C 1 -m 1 -l K112x2
You dont need to specify arguments for each card if you want them to run under the same settings.
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
I've been lurking this thread ever since I started mining a week ago. Thanks for all the hard work everyone has done.
I've got 2 EVGA 670 FTW OC'ed hitting 453 kh/s. Supporting hardware is an i7 3770k @4.6ghz, EVGA Z77 FTW motherboard, and 8gb of ram.
I've tried as many combinations of arguments as possible, and these 2 are getting me the same results:
-H 1 -i 0 -C 1 -m 1 -l K14x16
-H 1 -i 0 -C 1 -m 1 -l K112x2 <- way more consistent
About 220-230 kh/s on each card.
I've also noticed that if I put in an argument that cudaminer doesn't like, I have to reboot my computer since it drops my GPU clock speed to 750mhz and seems to lock it there.
I'm hoping for some more K20 optimizations in the future!

Howdy folks. I came into this about a week ago not knowing a single thing. I did all the googling I could and I'm currently mining with my Nvidia gaming rig. I know, it's not ideal. Might not even be worth it, but it's definitely got my interest. Perhaps when I'm not poor I'll put together a proper mining rig. Until then, I'm doing the best I can with cudaminer and hoping some advancements come along to improve my hash rate. Here is what I have managed so far. Peaking at 453 kh/s combined.

I'm running an i7 3770k @4.6ghz, EVGA Z77 FTW mobo, 2 EVGA 670 FTW's that are OC'ed as stable as I could get them, 8gb of ram.
