With commit 114 x86 Titan now getting around 620 kh/s  using
Code:
-i 0 -H 1 -l Z14x24 -C 1

This is up from 530 kh/s on 12/18/2013 giving a 17% boost over launch params
Code:
-i 0 -H 1 -l T14x32

Both of these on the same overclock -502 mem +155 core

As far as I can tell, b114 is just a little slower than previous build on my GTX760.

wait, there is a DP switch for cudaminer? what does it actually do? (aside from apparently lowering your performance)

DP switch is located in Nvidia Controll Panel. But it can be used only with Titan, because it have specific architecture.

Not that switch, the command line switch in cudaminer.
What does the command line switch called -dp in cudaminer do
What it does?
It does... not exist :/

Start with the build from the 2013-12-18 (first post) and just let it auto tune. You might have to start two instances, one with -d 0 and one with -d 1, but not 100% sure about that. Try with GPU-Z if you see the GPU load for each GPU-core, I hope that is possible.

I know what the DP actually stands for but am I the only one that had to double check what site they were actually on when they read DP...? haha

I have GTX TITAN, but performance looks similar (maybe not used DP):

with turned off DP: 485khash/s @ 770Mhz with -l T14x32
with turned on DP: 480khash/s @ 770Mhz with -l T14x32

btw. i don'n know, why clocks are such low with the latest version of cudaminer 18-12-2013, while gaming frequencies are 1045Mhz

If there is some bios editor which can turn off stupid turbo...it would be great :-)

There is KeplerBiosTweaker version 1.26.
However if you are running on low frequency it is most likely due to high temps/high power usage (assuming it works like the 780ti).
Try to increase the fan speed first (the card is by default optimized on silence....)

I got a friend who wanna try to start mining Litecoins, he got a GTX 690 so i told him that i'll help him Smiley

Anyone already configured his Cudaminer for this Bi-GPU card ? Is it harder to conf ?

error with starting custom compiled x86 scrypt-jane enabled was in file pthreadVC2.dll - this i have replaced from original x86 cudaminer binary and - it is running! :-)
x86 version has higher performance

Interesting is, that now on my titan this build is running at 1189Mhz instead of 836Mhz ;-)

omg, i want to save 1 hour of downloading and compiling etc... i think it can be usable for more people, not only for me.. afternoon i will try to compile and if success..upload it somewhere for other people.. :-)
Sigh, it IS on the LAST PAGE, the LINK to a UNOFFICIAL BUILD of CUDAMINER.
Man I should fix my CAPS key... wait it's not broken.


I have found correct link, but x86 version cannot be started for me "cudaminer.exe --help" writes windows error application 0xc0000007b.
x64 version is working.. has x64 version higher performance in comparison to x86 ?

This is false, the TITAN always uses 100% of its DP modules.
First, the titan is 1/3 DP, unlike the rest of nvidia lineup which is 1/24 DP

Don't tell that it is false, if you don't understand about what i'm talking about. I know difference between GK104 and GK110 architectures.
But by default TITAN works in 1/24 DP mode instead of 1/3.
Just read this article http://www.anandtech.com/show/6760/nvidias-geforce-gtx-titan-part-1/4 to clear this out.

AFAIK that is irrelevant because CUDAminer runs using SP processors anyways.
I can tell because the GTX780 Ti outperforms the titan by 25% yet the GTX 780 Ti has 1/24th DP while the Titan has 1/3rd DP. Had it been a DP process the ittan would have effectively 896 DP stream processors compared the GTX780 Ti's 120 DP stream processors.

As i said, Titan works in 1/24 DP by default. So don't be so sure, that CUDAminer uses SP processor.

UPDATE
I have GTX TITAN, but performance looks similar (maybe not used DP):

with turned off DP: 485khash/s @ 770Mhz with -l T14x32
with turned on DP: 480khash/s @ 770Mhz with -l T14x32

btw. i don'n know, why clocks are such low with the latest version of cudaminer 18-12-2013, while gaming frequencies are 1045Mhz

So DP doesn't have any positive influence on hashrate. Also, i've seen some way to turn off Turbo Boost on GK110, try to ask here http://www.overclockers.com/forums/

Guys, whose who own GTX TITAN, have you tried to enable full DP calculation mode?
I'm not sure, but i think that it will increase hasrate, because by default TITAN uses only 1\24 of his DP modules.
the TITAN always uses 100% of its DP modules.
First, the titan is 1/3 DP, unlike the rest of nvidia lineup which is 1/24 DP

What this means is that out of every 3 stream processors on the titan, 2 are SP only and 1 is DP.
A DP stream processor CAN operate in SP mode, but not vice versa.
As a result, the titans DP mode performance is 1/3rd that of its SP performance.

AFAIK that is irrelevant because CUDAminer runs using SP processors anyways.
I can tell because the GTX780 Ti outperforms the titan by 25% yet the GTX 780 Ti has 1/24th DP while the Titan has 1/3rd DP. Had it been a DP process the ittan would have effectively 896 DP stream processors compared the GTX780 Ti's 120 DP stream processors.

Full DP can be enabled in Nvidia conrol panel => Manage 3D Setting => CUDA double-precision, and there you should mark GTX TITAN option.

If someone have TITAN, can you test this mode, and post screenshots here?

Can you somewhere upload (custom) win build of cudaminer supporting scrypt-jane please?

Thank you very much! :-)
NO NO WE CAN'T!
BECAUSE IT HAS HAPPENED ON THIS/PREVIOUS PAGE ALREADY.
Explain to me why people do not have the balls to read some pages?
Also for some reason I cannot get rid of the capital letters in the first two lines of my response, weird huh? Must be a bug or something.
