Changing the hashing algorithm

My 7870 card can work,but p2pool say hashrate is zero . :(
**@ChekaZ ,how to fix ? **

Lizhi, you are forwarded to the strreaum of the pool,which isn’t working for neoscrypt.
Use the ‘–no-fixprotocol’ parameter on the command line.
Please check exact spelling with cgminer --help
-
Thanks , I update p2pool code. Now it work. :)
I can mine PXC ,can mine FTC-testcoin too .
-
I received those coin.
mine FTC-testnet command line: cgminer --neoscrypt --fix-protocol -I 12,8 --worksize 256,256 --thread-concurrency 8960,1120 -g 1 --shaders 1792,1120 -o http://pool.ftc-c.com:19328 -u TRsuTqxAMKZNvC7JzGNgvM49rkQNcxqjhi -p x mine PXC command line: cgminer --neoscrypt --fix-protocol -I 12,8 --worksize 256,256 --thread-concurrency 8960,1120 -g 1 --shaders 1792,1120 -o http://95.85.57.10:10554 -u PfF9PKBjkmz7gFAkA7h6ajY5AHc9B1mijW -p x -
Well done
-
Lizhi, tried__-g 3 ? just out of curiosity, not had a chance to play with it yet. (Note to self: never ask Lizhi mining advice, only financial >:D ) *runs off giggling*
Question: Is there any leeway under Neo to play around with transaction speeds, without changing block rewards/times, or is there too much risk of security issues with that?

ChekaZ, what are the cards delivering 40+ KH/s each?

OK ,your miner are working.

ChekaZ, what are the cards delivering 40+ KH/s each?
AMD R 280X

AMD R 280X
Your card listed?.. https://litecoin.info/Mining_hardware_comparison
I have to play a lot of trial and error with my cards, the 4 gig 270X’s (they outperform some 280’s with less power, why I went for the 4gigs, algo dependant) aint listed there and tbh, I really cba compiling for the linux box, I’m being lazy, letting the coders code before I poke at the new toys.
Just throwing this site out there, cause no way a 280 should be running at only 1k 1050 minimum, sure, ramp it up in 5’s from there, till the drivers crash, roll it back 5, start with a standard 1500 memclock
–gpu-memclock 1070 --gpu-engine 1500

No errors. This was running overnight. nVidia GeForce GT 630M

Also, Who was this? Spiked to 33,558 h/s

What does WU:x mean?
-
Gigabyte Gv-R7870C-2GD 7870 PCI-E
-
What does WU:x mean?
WU: The Work Utility defined as the number of diff1 equivalent shares / minutehttp://bitcoin.stackexchange.com/questions/19260/deciphering-cgminer-interface-in-terminal
So I’m guessing the higher the number the more efficient your miner is
-
Ah nice. Cheers.
-
Which version Catalyst is best ?
my 7850 ,7970 are HW ,not work.
-
I think 13.4 is the best, but 14.4 for me was only 1% or 2% slower so not a huge difference.
I was running 8.something and that would crash cgminer.
What version are you currently using?
-
I use AMD 14.4 Catalyst + SDK 2.9 .
Can you mine with AMD 13.4 Catalyst + SDK 2.8 ?
-
I could mine with just AMD 13.4, I didn’t have SDK installed at all, although I now have installed SDK 2.9.
I have a Gigagbyte HD7870 GPU, running Windows 7 64 bit
