Since i'm still a "noob" i guess i'll post here and hope for an answer.

I'm trying to set up the rpcminer-mod (whole thread found here: https://bitcointalk.org/index.php?topic=163750.160)

So, i'm firing this thing up using these parameters (yes, i know i should set up a stratum proxy, but up until now i've been using guiminer).

C:\Users\kepler\Desktop\rpcminer-mod-master\bin>rpcminercuda -url=http://api.bitcoin
.cz:8332 -user=kepler82.worker2 -password=[yea, no...]

And then magic starts to happen.

Client will start 1 miner threads
Work will be refreshed every 4000 ms
1 GPU GUDA device(s) found
Setting GPU GUDA device 0
CUDA initialized
Search Configuration for gpu named: GeForce GTX 660
Your device:
   - 5 streaming multiprocessors (SM)
   - can run sm version 300
   - bitcoin miner is optimized for 5 gpugrids per SM
   - max value for gpugrid parameter is 2147483647
max nonce 3FFFFFFF
Autotuning is on because no gridsize is given
Done allocating CUDA resources for (131050,256)
iterations on gpu=32 blocks=131050 threads=256
Iterations: 1,hashs per iteration 1073561600
Target = 00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffff


BOOM! My driver crashes (using version 306.97) leaving the screen blacked out for a couple of seconds. Then it'll turn back on with a message that the nvidia driver has crashed.
This is what the command line tells me:

<src\cuda\bitcoinminercuda.cpp>:193[CUDA] Error: unknown error

any suggestions?

(and any way of getting rid of the noob-status soon? i'm not a frequent poster, but when i do post it would be nice to do it in the appropriate subforum)

I am not familiar with rpcminer, but generally nvidia crashes like that when the miner tries something too much for it. I have 2x660ti
My guess - autotune tries a lot of combinations, some of which are too much. That is what happens for me with cudaminer (LTC), guiminer, cgminer.
Try reducing intensity, or whatever rpcminer uses for throttling.

Or if you give up, try cudaminer for LTC, with the latest version i get around 150kH/s, with two cards (~300-310) that comes to around 0.8LTC a day..

Find my post useful? Feeling generous? Coffee for me, karma for you Smiley

Ok. Thank you Smiley
I'll look up some documentation on rpcminer to find out how to throttle it.

Baww. some of us use our computers for other stuff than mining too. I, for one, like my framerate to be somewhat consistent while playing Smiley
