Reaper Miner Mining with GTX 550 Ti

[jmevz]

Hi All,

For some reason I can't get Reaper to use my GPU, rather, it's using my CPU. CPU usage jumps where GPU load stays below 10%. I'm trying to mine with an NVIDIA Geforce GTX 550 Ti.

reaper.conf

Code:

kernel reaper.cl
save_binaries yes
enable_graceful_shutdown no
long_polling yes

mine litecoin

litecoin.conf

Code:

host ltc.kattare.com
port 9332
user x.x
pass Xxxx


protocol litecoin

worksize 160
aggression 14
threads_per_gpu 1
sharethreads 8
lookup_gap 1
gpu_thread_concurrency 2047

Using the above settings, when Reaper is running, my CPU usage skyrockets and I can hardly use my computer, it doesn't appear to be using my GPU to mine at all. Any advice on setting the Platform, Device details to make this happen? Also, another n00b question, does Platform refer to the location of the device, in this case, PCI bus 2? Therefore, Platform 2? I've probably got that all wrong

Try CudaMiner with your nVidia card.

If I'm not mistaken I believe you have to put "platform 1" as I've indicated above.  Try that and let us know.  I use reaper and have had good results with it on both amd and nvidia.

Hi, I've put platform 1 device 0 within the Reaper.conf file. You've indicated putting it in the Litecoin.conf file too?

I've managed to get it to detect that there is a GPU there, but when I select Platform 1, Device 0, it just flashes quickly and disappears. I can't remember the error from memory. If I try Platform 1, Device 1, it reverts back to using the CPU.

Confused Beginner :\

Thanks

Apologies platform 1 is supposed to be in the "reaper.conf".  I don't believe you need to specify the device because it should autodetect that from the platform setting.

It's possible you may not have the proper libraries installed if it doesn't see the device after specifying the platform.

What flavor of Linux are you using?  Have you installed the OpenCL libs?  Maybe you aren't using the "nvidia" kernel driver/module and you're using the "nouveau" instead, I've experienced issues there.. I'm thinking you might need them.  Also can you do an "lspci -k" and show what's loaded for the VGA device?  Also do you have a monitor plugged in?  I can't remember off hand if that card turns off the GPU when no monitor is plugged in...

Hey,

So many variables, I'll have to throw your suggestions at it tonight. I'm running on Windows 7. I'll check out all of your suggestions plus, I have dual monitors connected, would that affect things as well? Too many monitors? I'm guessing it's more the drivers etc you've suggested causing me issues.

Thanks

I responded to your PM.  Keep in mind with Win7 there's a bit of a performance hit..
