[ANN] Yet another GPU miner release! [YAC]

[eule]

So no one's GPU is working? Did you try Intensity 10 (only way my card worked after last n change)?
Maybe HW errors can be ignored since the miner still delivers accepted shares. (A2 HW 8 this try)

[Mowcore]

All 3 of my gpus work, it's just they don't work at the intended speed (HW every 3 secs ). My 7970 was getting 110 kh/s before N change (-w 256 --lookup-gap 2 -I 13 --thread-concurrency 32832 -g 1), as the change happened it went down to 50 kh/s. Once restarted the miner the only stable speed is 25 kh/s (-i 12). This happens every n change , it's all me being a stupid mother fucker!.

I have 10 hw's just from starting the miner lol

[eule]

Well my 5770 gets 12.25Kh (half a 7970!  ), A:15 HW: 87 after 10 minutes, seems like the HW errors can be ignored for now (at least at I 10).

[Mowcore]

My 5770 seems to be ok at -I 10 like you said, core 950 mem 1250 --worksize 64 --lookup-gap 2 -I 10 --thread-concurrency 10240. no HW errors so far, 13.26 kh/s. at -I 11 it was 16 kh/s with a ton of hw's

When I lower the intensity on the 7970 the drop is like 20 kh/s though , way too much... working on that.

[eule]

Interestingly cgminer won't start at TC 10240, but raising it to 8000 indeed solved my HW errors issue.   edit: nope just a bit less A:3 HW:2, playing with TC now.
Had it at 5120 before, after the last n change the card didn't accept many TC values at all.
edit: 8096 and 8192 seem to be good.

[Mowcore]

How much ram does your system have? I have 16gb so maybe thats why I can go so high. Every N change the memory needed to solve a hash increases so i guess its all connected some how.

edit: maybe lol

No worries, the card has some problems anyways (have to turn the core down to 800 in 3D games or the driver crashes, mining at 850 and higher is fine though) and made ROI at least five times. Still think i should build a rig with 5 used 5770 for 300€.

On HD7970 with intensyty -11 i have 40Khs  without HW.

reject all    (target missed)

I use

cgminer --device 0,1,2 --scrypt -w 256 -I 10 --gpu-engine 1000 --gpu-memclock 1250 --thread-concurrency 8192 -g 2 -Q 0 -s 1 -E 5 -o http://yacp.coinmine.pl:8088


something wrong?   

[Mowcore]

I managed to get the 7970 going -w 256 --lookup-gap 2 -I 12 --thread-concurrency 42768 -g 1 stock core/mem 32 kh/s , temp was running at 70 c so not going at full pelt, no hw errors. Might be faster on better 7970's as mine is XFX bs

My 5770 has been artifacting and bugging out well before I discovered mining, I even sold it and got it back. I am glad as I have defo made my roi back on it, mainly from solo mining Yac plus I got it new 5 years ago for gaming, im happy with it. sure I can still sell it on ebay after I am done lol.

I tried with yacminer with 7950 and only get 55K with each of VGA hic

My configuration: cl V7

yacminer --scrypt -o http://yac.coinmine.pl:8088 -u xxx.1 -p x -w 256 --gpu-threads 2 --lookup-gap 2 --thread-concurrency 8192 --intensity 12 --gpu-engine 980 --gpu-memclock 1650 -d 1 -d 2

Have anybody get more speed? could you show your bat file for 7950 ?

[vivabnet]

So many HW error hic, 1 accepts in 20 minu

[digger]

http://yac.ltcoin.net  now has 1.6M hash/s

http://yac2.ltcoin.net has  0.5M hash/s

With the N change that is a pretty good speed for a 7950 (about half what most people got before).  Count yourself lucky, I can't get my 7950 to work at all now, only HW errors.

It is means that we have nothing to hope with GPU mining

yes,  i have only rejected and can't mining with 7950

[eule]

i have only rejected and can't mining with 7950

Many people (including me) can only mine on Intensity 10 anymore.
edit: Oh you tried 10 already. Maybe play around with the lookup gap and thread concurrency values.

Yes, you need to use yacminer not cgminer...
