I'm looking for some sort of guide as to how to setup the Reaper (GPU) miner on my main PC as it has a decent card I'd like to make use of.Is it possible for someone to make a config suitable for an HD6950 with unlocked shaders to make setup more painless so I can get past that compiling part when you first run it? How can I make sure it only mines LTC rather than any other currency in Reaper?

Any help would be appreciated.:)

in reaper.conf

Thanks for that:) Now to figure out the rest.

if you hop in #litecoin in freenode ill be glad to help

I've managed to get reaper running successfully on the PC now. I only get like 220k/hash on my radeon HD6950 though.What performance should I be getting with that card? What are the best mem and core clocks to use with that card? What settings should I use in reapers config for that card?

I have concurrent threads to 6144 like I was told from somcwhere else and gpu threads to 4.

Any help would be appreciated.My other thread about the laptop is now resolved but couldn't change the title to resolved.Thanks :)

If it helps at all, I did make this:

It was thanks to your video that I was introduced to easy LTC mining in the first place.The CPU scrypt miner is more straightforward due to  a clear GUI.Reaper is more difficult but not too hard. Thanks for the vid anyway :)  Does anyone on here know how to improve the performance of reaper on my HD6950 with unlocked shaders as that's the sticking point for me now? I'm only getting like 220kHash/s rather than what I was told it should be (at least double what I'm getting). What things should I overclock?Both core and memory? Or is having a more modest core clock but much faster memory clock going to help more? What core and memory clocks work well for LTC mining? Thanks.

PS.I know this is a little off topic but I know someone else who also needs help setting up reaper https://bitcointalk.org/index.php?topic=94193.0 (https://bitcointalk.org/index.php?topic=94193.0) and I'm out of ideas after suggesting things to the OP of that thread.

Film2240, you should be getting about double that hash rate... Make sure in reaper.conf you have the line "device 0" there, so that it doesn't try to mine on your CPU (which it can't... but it tries anyhow!), then bump aggression in litecoin.conf as high as you can go with stability, and try with changing settings like gpu_thread_concurrency to multiples of the number of cores on your card (1408?). Also try both 1, 2, and 4 threads per gpu :).

Thanks for the input.I'm going to try that.So putting device 0 can help reaper focus purely on my GPU and hopefully stop my CPU fans from spinning up (when reaper tries to mine on it too).No of shaders is 1536 on my card (as it's unlocked). As soon as I get a chance,I'll add this to my PCs reaper configs. Thanks :)

I'm happy to report that I've finally got reaper running successfully at high speeds with very few stales. I now get 454Kh/s or above on my HD6950 (unlocked to 1536 shaders) with these settings:

In litecoin.conf:
protocol litecoin

worksize 256
aggression 16
threads_per_gpu 4
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 6144

and in reaper.conf:
kernel reaper.cl
save_binaries yes
enable_graceful_shutdown yes
long_polling yes
device 0

mine litecoin

Adding 'device 0' is very important as this stops reaper from mining on CPU and GPU which degrades performance.

Clocks are (stable at):
885MHz (core clock)
1000MHz (mem clock)

Great success.I hope this thread helps those who need it. :)
