Title: Purposefully running a miner under-powered.
Post by: Jawfin on December 26, 2013, 01:05:14 AM

I would of posted on the cudaMiner (https://bitcointalk.org/index.php?topic=167229.0) thread, but for the obvious reason I am posting here!

My GeForce 660 Ti can mine at 275kh/s but for this my PC becomes rather unresponsive, even with -i 0. As I use this PC for work, as well as watching TV via a tuner card, is it possible to purposefully run the miner with a capped GPU% usage? Currently if I mine while using the PC it will crash/reboot unexpectedly, even using MSIAfterburner to attempt to stifle it, it also stifles everything the card does, including the OS GUI!

I would prefer to mine safely at 150kh/s then not at all.

Sorry if this has been asked before but I couldn't find any related posts.

Specs in case it's relevant: -

Code:

Command line: -
cudaminer.exe -a scrypt -H 1 -i 0 -C 2 -l K14x7 -m 0 -o stratum+tcp://blah.com:port -O Jawfin.worker:pass

Operating System: -
64bit Windows 8.0

So, it is possible to mine without running too hot and lower GPU use?

"even with -i 0." - if you want to keep your PC responsive, set "-i 1". In CUDAMiner, "i" means "interactive".

As to whether you can cap GPU% usage - I think CUDAMiner doesn't have such option.

Also, K14x7 is a weird config. For 660Ti, I'd use K7x32 for maximum efficency (7 SMX units * 32 warps), as described on http://www.reddit.com/r/Dogecoinmining/comments/1tguse/a_treatise_on_cuda_miner/ - it's possible that reducing the config to, say, K3x32 will help you, but I'm not sure.

@Jawfin Sure it's possible to purposefully run the miner with this config anyways you can can post on the "cudaminer" thread by now.

Thanks :)

As I started here though it's more polite to post the result of this question here.

I used K14x7 as that was the recommended setting from the debug benchmark.

Thanks Mivexil for your insight, and it works too! By using K3x32 it does control how much of the GPU is committed to mining. It runs at 85% GPU and at 65 degrees Celsius as opposed to 75 degrees (being 150F & 165F). Note its still running at 100% power, so I am not saving electricity but my computer is not crashing when I decide to maximise a window!

And yup, I meant -i 1; I think I was stuffing around I ended up confusing myself with which one I wanted >.<

Thanks for your reply guys :)
