Cudaminer - Help a newbie please!

[obzbdc]

Hi Guys and Gals,

So I've decided to jump on this whole mining thing but I'm not sure I'm getting the performance I should be, can anyone suggest any changes to the below setup to see if we can make this go any better?

I have 3 nVidia cards in the desktop I'm mining on, 2 X GTX590s & 1 GT 640, after an autotune I've ended up with the below settings:

(590) GPU0

Code:

-H 2 -i 0 -d 0 -C 1 -m 1 -l F16x14

= ~102kh/s
(640) GPU1

Code:

-H 2 -i 0 -d 1 -C 1 -m 1 -l K56x8

= ~43kh/s
(590) GPU2

Code:

-H 2 -i 0 -d 0 -C 1 -m 1 -l F16x14

= ~43kh/s
(590) GPU3 Main Display attached, not mining, even with -i 1 framerate drops to ~5fps and system is unusable.
(590) GPU4

Code:

-H 2 -i 0 -d 0 -C 1 -m 1 -l F16x14

= ~75kh/s

As you can see the performance of the 590s is all over the place, SLI is definitely disabled and I would have expected them to have similar performance or is there something I'm missing?

Also is there an easier way than trial and error to identify which device is which as far as cudaminer is concerned?

Thanks in advance for any suggestions!

Bill

Edit: OS = Win8.1Prox64, nVidia Driver Version = 332.21

-d will give you a list of devices and there number

Also, for every 590 you show -d 0..... after finding out which numbers they are you should used the corresponding number

Hi Tootapple,

Thanks for the reply, I do have them set as -d 2 & -d 4, that was sloppy cut and pasting, oops! 

as for -d giving a list of the devices that is what I was expecting to happen, instead I get the below:

Code:

try cudaminer.exe --d

Hi Again,

No luck still, --d gives

Code:

ambiguous option -- d

as it can't tell if I want

Code:

 --debug

or

Code:

--devices

. Extending out the command to

Code:

--dev

to remove the ambiguity gives the original error I was getting with

Code:

-d

Anyway not to worry, the device listing was more of a curiosity than anything. Any ideas on speeding things up though?

Thanks in advance,

Bill
