target-miss

[bitcoinharvester]

I have a triple 5870 rig that I am trying to move to LTC and when running cgminer or bfgminer I get all rejected (target-miss).
Any ideas?

Try other mining programs. Cgminer and BFG miner were tuff for me to figure out as well. I found minerd worked out but I don't have a gpu I been waiting for a pre order to come in but I have been experimenting with my laptop cpu.

Good luck

ps There are a great deal of self help ltc threads. The one created by Graet here on this forum was very pleasant to follow.Can't find it though....but here's one

Are you running cgminer with --scrypt?

Thanks Mooc,
I have read all of these and still no dice.  I have a win 8 machine (that I only setup to play with) with same setup that works fine.
I have been mining btc with the 3x5870 machine for a long time and it still works fine there.
I know it must be a config prob but I just don't see it.

C4n10,

Yes with script.
I have tried cgminer, bfgminer, and reaper all with the same results.
Many different configs, always the same.

I have over 10 machines all with 5870's or 6950's that are working but not this one?

Seems that I get all blocks rejected solo mining as well.  No gpu errors though.
Starting to get a headache!

You have the latest ati ccc: http://www.amd.com/us/products/technologies/amd-catalyst/pages/catalyst.aspx

The catalyst control ceneter comes with the opencl sdk necessary for scrypt mining.

I mine with a single Gigabyte 5870 SuperOC on cgminer and my litecoin setup looks like so:

Code:

cgminer --scrypt -o http://webaddress.com:port -u username -p password --thread-concurrency 8192 -I 18 -g 1 -v 2 -w 256 --gpu-engine 450 --gpu-memclock 1300

You will likely want to use lower thread-concurrency and gpu-memclock settings or not use those flags at all depending on your card, I have the Gigabyte Super OC which has twice as many shaders as the standard 5870 and is intended for extreme overclocking.

Kinda funny I have 2 of the same cards that you have and a ref card!
If I use that config cgminer crashes immediately.
if I use this:
"intensity" : "5,5,5",
"vectors" : "2,2,2",
"worksize" : "128,128,128",
"kernel" : "phatk,phatk,phatk",

"retry-pause" : "5",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
at any intensity it runs fine but every block or pool submission gets rejected.
Pulling my hair out soon, any help is greatly appreciated.

You are using the phatk kernel, you want the scrypt kernel

Finally found the answer in another thread.
Change from mining BTC to LTC?
ADD MORE RAM!!

Thanks for the assistance.

tried multiple pools? yeah try to get the same amount of RAM you have as memory on the cards
