I get the "does not validate on CPU" messages mostly when I choose kernel launch configurations that the RAM on the card does not support.
memory usage can be estimated by calculating blocks x warps x 4 MBytes where your -l argument to cudaminer specifies blocks x warps

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

i also get it if the con to the pool is lost for some time and afterwards being reestablished. a simple cronjob that kills and restart cudaminer every 5 minutes solves it nicely

i got a "result does not validate on CPU!" after starting cudaminer (after try (start) stratum_proxy) .. (coionotron)
what does that message mean?
remove the -l and -i -C parameters and use -D to find the best -l parameters for you.

Where is this from and what do you want to know/what do you want to fix?

<gutted out to save space> Where is this from and what do you want to know/what do you want to fix?
this is from litecoind daemon log file. I just want to understand what is going on and what i need ( if anything) to do ? for example: what does "CTxMemPool::accept() : accepted 46d7990963 (poolsz 37)" means? what is accepted and what is poolsz? what does "ProcessBlock: ACCEPTED" means? what does "force request: block" means? what does "getblocks -1 to 00000000000000000000 limit 500" means? what does "ERROR: FetchInputs() : 0f3a6ab0fb mempool Tx prev not found 0dfc0db223" means and do i need to do anything about this error? and finally "stored orphan tx 0f3a6ab0fb (mapsz 38)? this portion is something new - i haven't noticed before: 05/03/13 19:17:27 ProcessBlock: ACCEPTED 05/03/13 19:17:27 force request: block 8439de5375f48730c2e9 05/03/13 19:17:27 getblocks 346045 to 8439de5375f48730c2e9 limit 500 05/03/13 19:17:27 getblocks stopping at 346046 8439de5375f48730c2e9 05/03/13 19:17:27 getblocks -1 to 00000000000000000000 limit 500 05/03/13 19:17:29 Flushing wallet.dat 05/03/13 19:17:29 Flushed wallet.dat 22ms 05/03/13 19:17:30 CreateNewBlock(): total size 1225 05/03/13 19:17:33 getblocks -1 to 00000000000000000000 limit 500 05/03/13 19:17:39 ResendWalletTransactions() 05/03/13 19:17:40 Rate limit dFreeCount: 13685.4 => 13910.4
what is going on here? why is it " getblocks stopping" ? and why esendWalletTransactions() ? thank you!

I get the "does not validate on CPU" messages mostly when I choose kernel launch configurations that the RAM on the card does not support.
memory usage can be estimated by calculating blocks x warps x 4 MBytes where your -l argument to cudaminer specifies blocks x warps
I get this on Win7 when Chrome decides to muck with something; closing Chrome followed by restarting cudaMiner solves the problem.

Trying to read through all 37 pages of this thread... but I have a GTX Titan and using this to mine litecoins. Getting about 190 kh/s at stock clocks/voltages and no tweaking of launch config (just relying on auto-tune).
Does 190 kh/s sound right? Any flags to optimize a TITAN?

Closer to 300kH/s would be more realistic for a Titan (slightly overclocked, maybe). Aren't there any Titan launch configurations listed in the Google Docs spreadsheet?
Make sure you use -i 0

Using CUDAMiner on a GTX470 at 770MHz here - great speeds, 180-200kH/s! Thanks so much! GPU-Z says GPU usage hovers around 90% though, is something not optimized enough? I overclocked just the VRAM by ~15%, the GPU usage did not change, so it's not a memory bottleneck.

GPU usage may be reduced when running in interactive mode (which is now the default for display-driving cards). So use -i 0 and get another speed boost. Indeed overclocking the core clock works best, and the memory clock is not very significant.

Not without a Stratum Proxy running. No inherent support in the software.

Where are the Titan owners? Hello, we have support for Titan and I really need someone to test this. If you could post the result of a Titan autotune session with debug flags to the forum - that would be immensely helpful.
Do you still need some debugging on Titan? I have one, and am more than happy to help! Just PM me or reply to this thread.

i got a "result does not validate on CPU!" after starting cudaminer (after try (start) stratum_proxy) .. (coionotron)
what does that message mean?
remove the -l and -i -C parameters and use -D to find the best -l parameters for you. Just an FYI, the -D flag just turns on verbose output (Debugging). You'll still get an autotune just by removing the -l parameter, it just won't tell you all the things it's trying until it settles on the one it thinks is best.

I also first tried with no -i option and random -l AxB opptions. 6x2 is a good start Then I found if I use -D the program will doa grid search for me. Just rememer which AxB gives you the highest kh/s and use that AxB in the commandline in the future. Note that some older mining_proxy doesn't have the -pa option that lets you choose scrypt. better follow my instruction. the -nm and the --no-longpoll ones can be taken off.

Can anyone help me. I am not using Stratum/Proxy cause I don't know how to set it up with CUDAMiner.... I've tried so many settings, but for the past day/2 days I been getting all these fails + my acceptance rate is like every 2-3 minutes, takes a good while, now I don't know if this is because of a difficulty increase or what, I'll admit, I am nooby. http://gyazo.com/112d32b381e2146428edf6135addc3bfAnyway just want to know is it me, or the pools. I am building an AMD 7950 rig this weekend so hope these problems get solved otherwise I have to go to LTC :\ but I want to stick with FTC
