[ANN][YAC] Yacminer GPU miner for Yacoin

[Thirtybird]

What I don't get, is that if I'm mining at Nfactor 15, N is 65536. Why does rawintensity 7168 NOT work with a buffer-size of 3800 at lookup-gap 16?

One block is 128 bytes. 128 * 65536 / 16 = 524288 bytes per thread.

524288 bytes / 1024 / 1024 = .5MiB.

.5MiB fits into 3800MiB 7600 times: 3800 / .5 = 7600.

Therefore, max rawintensity without hardware errors SHOULD be 7600...

Your math matches mine 100%, and it should work.  If your drivers are something other than 13.12, that might be part of the problem - I've seen HW errors on configs that should work just fine on 14.X.

config for R9 270X for linux?

[lmaonade80]

Anyone mining YAC with 280x? What's your settings and how much are you getting out of it?

bump

I'm only getting 1.4 khs, and I'm told it should be much higher.

What were you told it should be?  NF=16 is tough when you've only got 3GB of memory

[lmaonade80]

When running YAC, on one rig, it just quits on me after 5 minutes - an hour of time. With "pause" in the bat file, it just lists the location of the miner \pause and "press any key to continue".

No heating issues (under 75), the computer remains running, and I'm about to gouge my eyes out here because I can't figure out whats wrong with it. Is there any method or other software that can explain to me why its crashing? Just one of two rigs I'm using does this.

turn off curses (-T i think) and enable debug (-D)

Well, I'm guessing you're mining zccoin, which is NF 16 - I'm guessing you've never mined a scrypt-chacha coin before?

Your buffer size is too low
Your lookup gap is too low
Your raw intensity is too high

read the primer on how to tune your miner for SC mining here : https://github.com/Thirtybird/YACMiner/blob/master/SCRYPT-README

there is also a config generator for ultracoin, which will work for your coin here : http://cfg.ultracoin.net/
it doesn't guarantee it will generate the fastest hashrate for your card, but it will be in the ballpark.

I change lookup gap , buffer size and R  but still HW.

And what command line did the config generator I recommended to you generate?

something like...

yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 8 --buffer-size 3532 -R 1664

Your R is still WAY too high, that's what causes HW errors

Error -4 Enqueing kernel onto command queue.

buffer size too high for system ram
not enough swap file
could be many things

Anyone still following this thread???

I am having issues with my R7 240 4GB cards... I am getting over 20% stale shares when mining YACoin. Anyone else run into that problem?
