Title: GPU for Nvidia cards - help pls Post by: HurrDurr|Lafara on July 16, 2012, 10:10:41 AM Hey everyone out there (:
I have a question about "how can i enable GPU for my Nvidia card" Graficcard: Nvidia GeForce GT 520 MX Processor: Intel Core i7-2670QM If i start guiminer make a new OpenCL miner i can only take "GeForce GT 520MX" and set the CPU affinity. So now I'm mining with CPU 5 - 6 MHash/s Is there any way I can enable GPU for my card and mine with GPU ( 5-6 MHash/s is really slow) Would be nice if anyone could help Title: Re: GPU for Nvidia cards - help pls Post by: RaTTuS on July 16, 2012, 10:13:50 AM from the command line in guiminer type
poclbm.exe and see what it says - you will probably need to point the device to the card i.e. -d1 Title: Re: GPU for Nvidia cards - help pls Post by: HurrDurr|Lafara on July 16, 2012, 10:17:35 AM If I open poclbm.exe in the guiminer folder it closes itself immediatly after opening...

An ATI is much faster Title: Re: GPU for Nvidia cards - help pls Post by: HurrDurr|Lafara on July 16, 2012, 12:06:54 PM Please note that CPU and Nvidia mining is VERY SLOW, you are just wasting time and electricity An ATI is much faster Yeah i know that, for that i want to change to GPU but i dont know how...

I will try to explane my situation^^ I have a Nvidia grafic card (GT 520 MX), I know that it's possible to mine with GPU with that card, but when i start guiminer and want to mine i only can select "GeForce G 520 MX" and i can select on how much of my 8 cores i want to mine, so the only way i can mine is with CPU. And my question here is how i can enable that i can mine with GPU with my grafic card. hope this is intelligible EDIT: i installed GPU Caps Viewer and under GPU it says "unknown", dont know why Title: Re: GPU for Nvidia cards - help pls Post by: John (John K.) on July 16, 2012, 12:54:07 PM from the command line in guiminer type Use this.poclbm.exe and see what it says - you will probably need to point the device to the card i.e. -d1 If I open poclbm.exe in the guiminer folder it closes itself immediatly after opening... Run using CMD as RaTTuS said above.Title: Re: GPU for Nvidia cards - help pls Post by: HurrDurr|Lafara on July 16, 2012, 01:00:26 PM then it says:
Traceback <most revent call last>: File "poclbm.py", line 48, in <module> pyopencl.LogicError: clGetPlatformIDs failed: inavild/unknown error code EDIT: I'm now mining with rpcminer-Cuda 10-11Mhash/s . It's the best i get or can it also be better? Title: Re: GPU for Nvidia cards - help pls Post by: senesazi on July 16, 2012, 05:06:32 PM GT520 is a pretty low-end card, so yes it seems adequate. Comparable really with the about 13MH/s I was getting with a 9600GT.

Does anyone know why it is that Nvidia cards are so much worse than ATI?
