I go to run reaper.exe the first time, and I get:

calclCompile failedError: Creating kernel search failed!
(dateTime stamp) Error: Error building OpenCL program

Anyone got any advice?

What driver version are you using?

I assume you are asking about my GPU driver... It's a 5770 running the 8.850.0.0 from 4/19/2011... the automatic windows driver search says it's up to date.

Things are a different now.

(i made a post on forum.litecoin.net but the DNS isn't resolving right now)

It turns out I got your tutorial and someone else's confused.

I can solo mine with on my 2nd computer with your setup. So I want to mine to my other computer, from my personal one, but it's not working.

I set up my router's port forwarding of 9332 to point to my 2nd computer, at 192.168.1.27.
I set up litecoin.conf (on that pc) to accept two ip's: 127.0.0.1, 192.168.1.*.
I start cgminer with -o localhost:9332 and works beautifully. In fact, I've already found a block.

On my PC, I run cgminer with -o 192.168.1.27:9332 but it doesn't do anything. It stalls after it finds that the pool is alive.

Hmm... both these computers are on your internal network, correct?

If this is the case, then I don't think you need to do any port forwarding. Have you tried scanning that computer from your other computer (that computer being the one that is 192.168.1.27) for port 9332 being open?

Hi. I am trying to mine litecoin with your setup to no avail.

I have been mining bitcoin for over a year on this 6870 with no problems.
I have a 4 core AMD processor.

With ScryptMiner, I can get 10kh/s with 6 threads, less at higher threads. (is that good?)
Reaper doesn't even work.

I am trying it out on my personal desktop, which I use the 6870 as well as a smaller 4000 series, to run 3 monitors. I want it to use the main GPU, which is device zero. So in the config file I put "device 0" w/o quotes. I have lowered my aggression to 9, and still, it hangs at:

Compiling kernel... this could take up to 2 minutes

Any suggestions?

cgminer sometimes works, sometimes doesn't. I am very confused. Please help anyone.

Very weird... what slot is the 4000 series in on?

I get a crash when I run reaper. The output looks like this in the console:
[snip]

What drivers are you using? Did you over(volt/clock)? Does cgminer work? Have you mined Bitcoins before? Is the card stable at other times? Can your PSU support full load?

Thanks for the clue. My problem was old video drivers.

Thats probably a good point. I downvolted my gpu some time ago to lower the heat but its a point to look at. At the moment im testing mining lite & bitcoins at the same time and now have cpu-temperatures at 89°C and the gpu is at 77°C. The notebook is placed on a desk only. So i think its not getting too hot at the moment. But i have to check first what temperature is dangerous then. And warm weather should be taken in account too.

Edit: Maybe i should mine for pools and check out what combination brings the most at the end.

Ok, than its the hashtype. Didnt know that till now. But i still think its strange that the gpu is slower than the cpu. Maybe only real fast gpus are a threat to litecoin cpu-mining like stated in other threads.

I played with aggression. Aggression 18 leaded to crash of reaper. With 8 it runs but it creates dots on the screen. I think somethings crashed then because it remains even after reaper is off.

The speed is the same when using reaper and cgminer for litecoinmining. So i think its probably normal for this gpu.

So bitcoinmining will be the best in this case? I mean cgminer eats 50% of the cpu now, when mining bitcoins while having a speed at 6.9MH/s. So mining litecoins would be slower when i would mine them with cpu at the same time.

So now i have the choice to mine litecoins alone at 7kh/s with cpu. Or mine bitcoins (or other) at 6.9MH/s or mining litecoins at 6.4kh/s and bitcoins at 2.4MH/s. Whats best?

I personally would focus just on cpu-mining Litecoins, primarily because laptop GPUs, while they are quite slow especially for number crunching, are also very limited in heat dissipation. Long-term, such high temps in your GPU will probably do more damage than is worth it from the small amount of BTC you would make.

Yes, cgminer looks nice. But unfortunately the hashing rate is very low. Its the same with reaper. Its only 0.6KH/s and its using more than 50% of my cpu too. While when i mine litecoins with my cpu i get 7kh/s. So its a bit disappointing. Its 9600M GT and i thought it will be faster than a cpu at least. But this way gpu wouldnt be a danger to cpu-mining litecoins.

Maybe i should mine bitcoins with the gpu. Starting cgminer without --scrypt shows hashrates of 7MH/s, which is 1000 times more than for litecoins. Or should i mine namecoins, solidcoins or similar?

I would not recommend mining litecoins with that GPU at all. Mining bit coins wold probably be preferable, but it's still really slow. The thing about kH in Scrypt vs MH in SHA256(x2) is that scrypt is about 1000x harder, so if you get 7MH Bitcoin mining, you should be expecting around 7kH/s Litecoin mining. However, this doesn't seem to be the case with you. Have you tried playing around with the aggression and putting "device 0" (without the quotes) in your reaper.conf file if you are using reaper?

I got 100% stale on some of my GPU, others don't. Is this normal ?

GPU 1.295MH/s, shares: 0|16, stale 100%, GPU errors: 0.01716%, ~1293.17 kH/s, 4745s

A lot of people seem to be having the same problem, let that run for about 8 hours and see if you solve a block

Thanks for the tutorial. I was able to setup scryptminer but reaper doesnt work. I tried to run cpu-only mining litecoins only and it told me that a config was missing about threads per cpu. I added the config and then it told me that litecoins cant be mined with reaper. oO Then i used the normal exe and it had the error that it cant connect to OpenCL. I have a NVidia GeForce 9600M GT and i can mine bitcoins with it by using guiminer. So i think everything needed is installed.

By the way... are these 2 miners the fastest to mine litecoins with cpu and/or gpu?

Thanks!
Sebastian

Hey, try cgminer for Scrypt
