looking foward for this...seems nice
May 24, 2014, 09:38:36 AM
I'm testing on older AMD cards, ie 5870,6950,6970,etc... Using -k x11mod and I=15....
I'm getting 1.8~1.9mh/s, but the shares are -0.0000/0.0000.
Original hash was 1.1~1.2.
It does seem the coding still need some tweaking to work right.
You got that right. I'm getting 1.8~1.9mh/s, but the shares are -0.0000/0.0000.

It does hash and find work, but doesn't submit shares....

-I 18 - 20 causes the AMD drivers to crash
yep... they recommend nto going higher than -I 15
Hoping this gets tuned up a bit better. Seems just a bit slower than the 2% fee scuzzball

i'm not getting any speed increase (2.1 mh/s 280x & 7970) over the normal sph-sgminer with darkcoin kernel on windows 7 64 bit.
The 2% version speed was 3.1 mh/s for both cards
Did you select the x11mod kernel? Sounds like you omitted -k x11modThe 2% version speed was 3.1 mh/s for both cards
Your version with settings : -k x11mod -I 15 --gpu-engine 1050 --gpu-memclock 1500 --thread-concurrency 8192 --lookup-gap 2 --gpu-powertune 20
2% version with settings: -I 20 -w 128 --gpu-engine 1050 --gpu-memclock 1500 --thread-concurrency 8128 --gpu-powertune 20
I have tried different parameters but nothing changes

you need intensity 15 for 3.15M/s, but the share value are all fucked up, they are negative, something wrong in the code

displayed best share is wrong, is negative, diff also is at 0.000, something in the type of digits in the code
i'm not a coder, but i'm curious what "sha256(pool->coinbase, pool->swork.cb_len, merkle_root);" does
This is not a my modification.
Maybe this code from cycle below...
Amazing, on Linux this works )
i've done some code in the past, but swork.cb_len, merkle_root i really don't know to what they refer
I identified and corrected the problem https://www.dropbox.com/s/skv74wv378h5qnl/sgminerx11.rar
The problem is the use of an unitialized variable as an index.
i.e
I applied a dirty fix by removing said IF sentence, simply because it's not needed for darkcoin.

Windows build report: shares with diff -0.000 and speed jumps from 2.1 to 2.6 up and down, up and down.

I am looking into the issue.
Unfortunately, I haven't programming experience on windows.I used sources from https://github.com/Atrides/sph-sgminer
Modded files
configure.in
ocl.{h,c}
driver-opencl.c
findnonce.h
miner.h

Won't start, win7 x64. Compiles, sees pools, then stops every time. Tried changing various parameters but same result every time.
