Dear jMiner users with dedicated GPU Cards
-
This topic is about dedicated Graphics Cards. 0 and 0 are not the numbers I am looking for.
-
@daWallet by dedicated you mean an additional card? its "0 0" unless the integrated intel was enabled after, it will be "1 0"

When u start jminer usually u will get info what is the ID of ur platforms and devices. Did u check that first? based on that u gonna choose the ID u are looking for.

@daWallet I am using a laptop for mining with a HQ CPU and Intel graphics, with a Nvidia dedicated graphic card as well. I set the
platformId=1
deviceId=0
in order to use only the Nvidia card for mining, with 0 and 0, works fine as well, but much better using Nvidia.
-
@daWallet The two of mine that I checked are both also 0 0
-
I use 0 and 0, but I am wondering if 0 and 1 might give better performance if I have a very large amount of TB to be read.
Both of these platform and device IDs correspond to my two dedicated GPUs, but 0 0 runs the monitor.

Just started playing with it. Does not see my plots for some reason. But I have platformId=0
deviceId=1This picks up my Intel Open CL version 2.

@Propagandalf It won't enhance performance, its just pointer to use which GPU on your machine.
Use "GPUplotgenerator setup" and choose option 1 to list all devicesfor example:
Dedicated GPU while disabling integrated GPU:
[0] AMD Accelerated Parallel Processing (OpenCL 2.0 AMD-APP (2117.14)) [0] Ellesmere (OpenCL 2.0 AMD-APP (2117.14)) [1] Ellesmere (OpenCL 2.0 AMD-APP (2117.14)) [2] Ellesmere (OpenCL 2.0 AMD-APP (2117.14)) [3] Ellesmere (OpenCL 2.0 AMD-APP (2117.14)) [4] Intel(R) Celeron(R) CPU G1840 @ 2.80GHz (OpenCL 1.2 AMD-APP (2117.14))Dedicated GPU while operating the integrated GPU:
[0] NVIDIA CUDA (OpenCL 1.2 CUDA 8.0.0) [0] GeForce GTX 970 (OpenCL 1.2 CUDA) [1] Intel(R) OpenCL (OpenCL 2.0 ) [0] Intel(R) HD Graphics 530 (OpenCL 2.0 ) [1] Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz (OpenCL 2.0 (Build 359))

@rnahlawi I appreciate the info, but I already knew that =) 0 0 is my GPU that is assigned to the monitor. When plotting, you will get a performance drop if you are using a GPU that is assigned to the monitor, compared to a standalone GPU. Therefore my theory is that I may be able to get better performance with mining too, if I use a GPU that is not assigned to monitor. But, I would have to have a very large amount of plots before that may become true, as mining is not as resource demanding as plotting.
-
@Propagandalf That's why you enable the integrated GPU and connect your monitor to it. I mean when you use the Dedicated GPU to plot/mine, machine becomes unstable. But performance won't change as integrated will use the CPU resources, or at least that's my case.
-
@rnahlawi My mobo or CPU does not have an integrated GPU, that's why I'm using one of my rx 470s for the monitor as well. I agree with what you are saying :)
