[ANN] YACMiner - AMD GPU miner for Scrypt-Chacha, N-Scrypt, and Scrypt coins

[bitcodo]

YAC: R7 240 4GB

Code:

--scrypt-chacha --buffer-size 3376 --no-submit-stale  -w 256 --rawintensity 1280 --lookup-gap 2 --gpu-threads 1

2.9 Kh/s

MicroCoin: crappy 7950 3GB

Code:

--scrypt-chacha --starttime 1389028879 --buffer-size 2100 --lookup-gap 2 -w 256 --rawintensity 6400 --queue 0 --scan-time 2 --expiry 4 --gpu-threads 1

110 Kh/s

still testing

for MRC weird A and U (U=80)

I can't get right settings for 7950, what settings should i use?

You need to say how much memory the card has... post YOUR command line and I'll explain the differences that need to be made.

I tried the command line you posted above for R7 250. my card has 3GB memory

It's going to be wild speculation - you WILL need to experiment on your own, unless someone wants to loan me one for a week or so, then I'll have the perfect command line

Code:

yacminer --scrypt-chacha --worksize 256 -g 1 --lookup-gap 8 -R 5120 --buffer-size 2560 -o stratum+tcp://yac.coinmine.pl:9088 -u username -p password

You've got so many shaders and can't use them all at lower lookup-gap values, so we try here to use them to trade off for the lack of memory by increasing the lookup-gap.  8 is probably a decent place to start (we like 1,2,4 & 8, the others are oddball sizes).  I'm assuming you can allocate 2,560 MB in one thread (i.e. you have more than 4 GB system memory - if you don't you are going to have a bad time), and at lookup gap of 8, that amount of memory can only support 5,120 simultaneous threads at N=14, so that's the value for -R.

Another theory would be to try lookup-gap 12 and -R 7168 - I don't think the extra work being don by the extra 2048 shaders will make up for the extra 4 runs through on the lookup gap, but like I said... wild speculation

Nice settings!  The R7 240 4GB is spot on for my findings.

On your MRC miner - if your 7950 has 1792 shaders, I would see if you can take the --rawintensity to 7168 - everything else being the same.  6400 would be where I would be if I had 1600 shaders.  A secret I'll share is that for settings that aren't memory limited, I just use "-X 4" and don't even do the math to figure out the -R

U of 80 isn't unreasonable for 110 KH/sec - if you're getting a lot of rejects or HW errors, that will suffer.  If you're getting HW errors, (I would be surprised),lower the -R.  That value also normalizes over a long period of time - some start off like gangbusters, some start out REALLY low, but they all work their way to an average after a couple days.

[ivanlabrie]

Interesting...thanks for sharing master 

[bitcodo]

It sems that A and U are simply multiplied by 16 when mining MRC.

7950 is down to 80 Mh/s again with --rawintensity 6400 or 7168     club 3d

ok tell me if this is normal, i used your suggested command line, first time i don't see any HW but rate is just 5kh/s is this normal for my card?

That's a pretty great rate for a card mining YAC....  compare it to all the cards on the YACoin wiki http://yacoinwiki.tk/index.php/Mining_Hardware_Comparison and you'll find it compares really really well...  Now that you aren't getting HW errors, overclock it until it's unstabe!  (and then bring it back down until it is stable...)

enjoy your hash mate - none of my cards get over 3 KH/sec

There's more math to it than that, but if your pool doesn't use vardiff then, yes, they will be different by a multiple of whatever the pool difficulty is.

[ivanlabrie]

5kh/s out of a 7950?

That's pretty crazy...

[Thirtybird]

5kh/s out of a 7950?

That's pretty crazy...

It's only got 3 GB - I'd guess > 7KH/sec if it had 4 GB and overclocked well

That'd be insane...I mean, haven't seena any do so well, but haven't tried it myself either. hmmm

Ok thank you that helped a lot. yeah i get 4.97kh/s stable with no HW
I will post screenshot after some attempts of tuning

I have been trying the new yacminer version on bitleu, but so far I got only driver crash.
I have been using this config on the previous version 3.4.2-yac2 without any problem on a R9 290x
What would I need to change, to get it work with the new version ?
I changed so far scrypt into scrypt-chacha.

{
"pools" : [
   {
      "url" : "127.0.0.1:8877",
      "nfmin" : "4",
      "nfmax" : "30",
      "starttime" : "1394480376",
      "user" : "dom",
      "pass" : "password"
   }
]
,
"xintensity" : "96",
"vectors" : "1",
"worksize" : "512",
"kernel" : "scrypt-chacha",
"lookup-gap" : "2",
"thread-concurrency" : "16897",
"shaders" : "2816",
"gpu-engine" : "1030",

Thanks for your help.

that should be all you have to change.  start with xintensity of 4

I can't seem to pass the -R or --rawintensity flag in a conf or in an .sh file in linux.
Every time I use it it closes on startup ?

./utc_mine.sh: line 1: 18391 Segmentation fault

Add -T and -D look for messages about what went wrong

Further edit: I definitely did something wrong, linux noob...I don't see fan speeds nor temperatures, so something related to ADL. :/

Thought you said it crashed on startup?

run "./yacminer -n" (dont use any scripts on anything) - does that work? 

it compiles and that runs on my ubuntu box, just doing the git clone, running autogen.sh, and make.

It runs, but I can't get raw intensity going.

Last person who told me this was actually launching a diffeent version of yacminer someone on his machine as he wasn't using the "./" before yacminer when launching.  launch with a -V to get the correct version number.  Try launching with a -I set and change to raw intensity through the interface (so long as you have curses) - it's on the same menu as intensity, so hit "G" and then hit "A" if it's on the menu.  If it isn't , what the heck are you doing???
