Changing the hashing algorithm

lizhi

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?

OK ,your miner are working.

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

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 / minute

http://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.

tmuir12

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?

lizhi

I use AMD 14.4 Catalyst + SDK 2.9 .

Can you mine with AMD 13.4 Catalyst + SDK 2.8 ?

tmuir12

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

Flobdeth

There have been known mining issues with 14.4 since release, 13.12 max on windows.

lizhi

The best choice:

AMD 13.12 Catalyst + SDK 2.9

AMD 7850 CARD =48Khash/s ;

AMD 7970 CARD =16Khash/s ;

cgminer.exe --neoscrypt --fix-protocol -I 12,12 --worksize 256,384 --thread-concurrency 8192,8192 --shaders 1024,2048 -g 1 -o http://pool.ftc-c.com:19328 -u TRsuTqxAMKZNvC7JzGNgvM49rkQNcxqjhi -p x

I gave it a try last night on my nVidia 550M, Win7 and I got max 8 khs. Mostly default settings, --worksize 256 -I 13, no overclock. Driver version 294.10 - a bit old

76C gpu temp -> not bad

I think it can reach up to 10 khs with some tweakin

This is what i get with -I 14

Limitation of the gpu?

And whats the logic 7850 to perform 3 times faster than 7970?

Do you guys expect the stratum implementation to raise the productivity significantly?
