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

[Thirtybird]

I tried "--device 5" and get it working on about 3K speed when "--buffer-size 670", but only get HW. Even I tried "--buffer-size 480" but no A showing up. There's no message come up.

That config I post was working for MRC when N=10. Means last and last N-factor. My mistake.

If you're allocating less memory, you have to raise the lookup-gap or lower the intensity.  If you cant only get it started at BS=670, then try lookup-gap 6 and -R 3840

It get the same result: no message, around 3.8Kh , only HW return.

My config:
yacminer -o stratum+tcp://mrcus.nut2pools.com:6000 -u abc -p abc --nfmin 4 --nfmax 30 --starttime 1389028879 --scrypt-chacha --worksize 128 -g 1 --lookup-gap 6 --buffer-size 670 -R 3840 --device 5 --temp-target 80 --temp-overheat 90

So confused

Post your system specs please...ram, board, cpu, gpus.

If you're only getting 3.8KH/sec and HW errors abound, it sounds like you're mining a pool at NF=14 (look on the pool connection line, look for NF=XX).  The settings I gave you are for NF=12, if you're on an NF=14 coin, then they will not work.  I pasted those exact settings on my machine with a 7850 1GB card and it hashed properly.

You're leaving out something important (like multiple pools configured, and not configured properly) or have something wrong with your machine, or are just trolling us.  Run with your settings, hit "S" to bring up the settings menu, then "W" to write out a config.  Save it to some file and paste the ENTIRE contents here.

As you said, I removed multiple pools from config, then make some progress, YACminer return both A and HW instead of HW only.

-lookup-gap 6 --buffer-size 670 -R 3840:
get 15Kh/s , return A and HW

-lookup-gap 5 --buffer-size 670 -R 3840:
get 17kh/s, return A and HW

The config file is:

The pool is all right because of my 280x machines working fine, and its N=12 .

Thank you for your patience, I'm not so good at English, and really in trouble with the config.  I'm so sorry if there were any misunderstanding.
I appreciate YACminer and try to use it with my 7850s, that's it.

I'm considering whether to use "-g 2" cooperating with other parameters could solve the HW issue?

Thanks.

That exact config should _not_ give HW errors for Microcoin.  Lookup-Gap 6, Buffer-size 670, raw intensity (-R) 3840 is likely the top config for that card.

Hoping maybe you can help me out...
I have an ASUS R7 240 with 320 shaders and 2GB ram. My system has 3gb of RAM total. Running Ubuntu and thats the only thing running. Any combination I try, the best I can get is a 1:6 ratio of errors to accepts.


--worksize 256 --gpu-engine 1100 --gpu-memclock 1000 --gpu-powertune 20 --no-submit-stale --lookup-gap 2 -R 1280 --scrypt-chacha -g 1

That goes straight into HW immediately. Any ideas?

Of course it does.  2GB is not enough to run a lookup-gap of 2.  You didn't post your buffer-size setting, so I'm guessing, but depending on how much memory you can allocate, you can run LG=4 or LG=3 with a reduced -R parameter (might be faster).  So, try a buffer-size of 1712 and LG=13.  If you can't allocate a BS of 1712, allocate as much as you can and start lowering your R until you stop getting HW errors.  Then, so long as you can allocate at least 1280 for buffer-size, try again with a lookup-gap of 4 and -xI of 32 instead of -R 1280.  Then pick whichever setting gives the higher hashrate and pay attention to your U: value.

If you can't allocate 1280, well, that's a whole different set of problems...

[bitcoinvideos]

Ok here is where we are at now:

The following yields 1.8khs with U: 1.5 avg:
--lookup-gap 4 --xintensity 32 --scrypt-chacha -g 1 --buffer-size 1708

The following yields 1.795khs with U: 1.76 avg:
--lookup-gap 4 --xintensity 32 --scrypt-chacha -g 1 (allowing the card to set buffer size results in 1496mb usage)

The following yields .6khs with U: 0 (didn't accept a share in 2 minutes so stopped it):
--lookup-gap 13 -R 1280 --scrypt-chacha -g 1 --buffer-size 1704

So I feel like this is much closer to being right on but I'm wondering how we can get it over the 2khs mark...I'm also running the following:

--worksize 256 --gpu-engine 1100 --gpu-memclock 1000 --gpu-powertune 20

Forgot to include that...

You need more system ram...I use 8gb for my 4 r7 240 2gb cards and get 2.35kh/s out of each.

lookup-gap 3 did the trick for me and my sapphire crap cards.

Ok so dropping the LG to 3 on --xintensity 32 --scrypt-chacha -g 1 --buffer-size 1708 I'm knocking around 2.2khs with a U of around 1.8 still...this is looking much better...thanks to both of you. Yes I plan on dropping some more RAM soon into this cpu/board but gotta make the money to do so. Thanks again!

You may get the occassional HW error with those settings FYI.  But it's real close (hence why I recommended BS=1712).  Don't forget to crank up the GPU and memory clock!  My cards run between 1065 and 1100 GPU clock with 1000 memory clock on all of them.

1100/1000mhz here, you need special software or bios mods to get so high.

[Hilux74]

1100/1000mhz here, you need special software or bios mods to get so high.

What cards are you running?  My Sapphire R7 240s can be set to that level and above within yacminer.  1150 is as far as I have tried.

[bitcoinvideos]

I am running 1100 / 1100 just fine yacminer on ubuntu. Everything is holding steady guys! Thanks again for the help.

My crappy sapphire cards had a top limit of 1040 or something like that, can't remember since I bios modded them long ago.

I'm running the ASUS 2gb models.

[Trokhon]

I use a R9 290 Saphire card and get only HW errors. Could anyone post a working config for this card please. I have 32GB RAM in my machine
