[ANN][YAC] Yacminer GPU miner for Yacoin

[ivanlabrie]

Hmm, thought yacminer worked with the sj-**** variables to mine other variable n factor scrypt-jane coins (?)

Can't get mine to do UTC (was experimenting a bit with a new card...r9 270 2gb)

It does, so long as you're running 3.4.2.  I mined ThorCoin with it for giggles, and lottery tickets too.

Hmmm, I'll try again later tonight. Thanks.

let me know if you have problems.  BTW - the new version I'm working on fixes the scrypt support and adds N-Scrypt support, so you can actually use one program for pretty much any scrypt derivative coin

That would put you on cudaminer levels of awesome, but with failover support, and other goodies (more awesome :p)
I hate having all those crappy cgminer forks made by who knows who in my pc...not a dev, as to examine the source code myself anyway.

I was using 3.4.2 and 3.3.1. Somehow memory got stuck at 500mb even if card was not doing anything. I had to disable card in windows and than enable it again. It is working ok now. maybe something went wrong with my card or maybe the program. Just to let you know.

For R7 240 4GB (from wiki): --worksize 128 -g 2 --lookup-gap 2 -R 640 --thread-concurrency 24576

Isn't 24576 weird number? I use 25600 (20x1280) and it works great.

24576 is just 1536mb per thread with LG 2...I have to run 40696 with LG 3 on my 2gb cards for some reason. If I do the equivalent with LG 2 I get HW. lol :p

[bitcodo]

Aha, thank you.
I get it now, just  --rawintensity values need to be in multiples of 8 (at a minimum), and older cards appear to need a multiple of 64.

Can anybody recommend me a setting for my AMD 6990 m getting low Hashrate abt 1kh/s ..
help appreciated!

YACMiner has been updated to 3.5.0 today - see post in main thread

hello

i have some problem with yacminig.

my settings:
yacminer --scrypt-chacha -o stratum+tcp://yac.coinmine.pl:9088 --worksize 256 -I 8 --buffer-size 1576 --lookup-gap 2 -g 1 --thread-concurrency 16384 --auto-fan --temp-target 73 --temp-overheat 80 --temp-cutoff 85 --gpu-engine 1150 --gpu-memclock 1500 --gpu-powertune 0 -u xxx -p xxx
and i have 2 r9 270 sapphire toxic driver 2013.12 opsystem win7 x64 sp1 i use yacminer last 3.5.0

my problem two gpu running different speed and i think low speed

gpu 0 140-180 h/s
gpu 1 400-440 h/s 

all card not 1 kh/s

i read this forum trying many settings and not working i hope somebody have good idea.

thank you

Your settings are definitely all over the place, and not good.

yacminer --scrypt-chacha -o stratum+tcp://yac.coinmine.pl:9088 --worksize 256 -R 3072 --buffer-size 1576 --lookup-gap 8 --auto-fan --temp-target 73 --temp-overheat 80 --temp-cutoff 85 --gpu-engine 1150 --gpu-memclock 1500 --gpu-powertune 0 -u xxx -p xxx

I replaced -I 8 with -R 3072 to get more threads going on the card.
I replaced --lookup-gap 2 with --lookup-gap 8 to let you use more threads with only 1576 MB of GPU memory
I removed -g 1 as it's redundant
I removed --thread-concurrency 16384 as it's overridden by --buffer-size and --buffer-size is an easier setting to work with.

Post your new hash rate back here - I bet it's much higher!

hello
thank you so much the answer wery helpful my new hashrate (5s):5.307K (avg):5.214Kh/s
only settings i change the buffer size 1576-1570  1576 not workin for me gp0 also slow down and the system memory +2 gb filled 1570 working. this 5.2 right hasrate this card ?
thank you

[ivanlabrie]

5.2kh/s with no HW?

Those are 2 or 4gb cards? 

[echo00114]

hello
toxic 2 gb version

http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2038&psn=&lid=1&leg=0
bye

and yes no hw i start aprox 5 h ago

only reject 3 % aprox.

bye

Yes, that's a pretty good number for that card.  Thanks for letting us know your results!

ivanlabrie - yes, now that we can tune the cards a lot finer, we can get decent hashrates out of them.  At -R 3072 his intensity is halfway between -I 11 and -I 12.

[ivanlabrie]

Trying to understand the thought process...

-i 8 = 256 threads?
So i 11 = 2048 and 12 4096?

What I don't understand completely is the way ram allocation works for different algorithms and n factors.
For instance, say we want to configure an R9 270 4GB card to mine vertcoin and the n factor at the moment makes the algorithm use twice as much memory as it does today (like a year had passed).

The card has 1280 shaders, 4gb of ram. Max amount of threads it can run in this scenario should be calculated as follows (88% of the ram is usable in this theoretic scenario): T*(512/LG)=3700987 ->vram expressed in kb

Is that correct?
As for lookup gap, it depends on if the card has enough ram to allocate all threads in the buffer that saturate the shader count. How do I determine that? Trial and error?

I ask because I want to create a tool to auto-tune cards for different algos and n factors based on your logic.
Thanks!

Gotcha :p

I think the readme has all the info I ask about lol...missed that.

hello
again thanx the help
one question left

the -R how calculate the number 3072 i cant understand
please explain me if possible.
thank you
