[ANN][GRS][DMD][DGB] Pallas optimized groestl opencl kernels

[pallas]

I suggest everybody keep "good binaries": make a backup of the fastest .bin files you have, so you can recover them in case of driver problems.
Also this will enable you to get 1 o 2 percent more hashrate because of compiler variance (try removing the bin and running 3/4 times to see the variance in action).
Or use the provided bin file (see the OP) which should be a good one.

I've added a "final advices" section to the second post with the quoted text and this one:
"I've experienced lower power usage with catalyst 14.9 compared to 14.6 beta (a bit less compared to 13 but still better). Speaking of optimization, this should be kept in mind: buy a power meter for your miner(s)!"

Hi,

4gpu 280x = 69Mhs

This is for DMD, right? Could you share your full set of parameters passed to the sgminer?

Me, on 280x I can't get past 7.45 Mhs, with the sph-sgminer version 4.1.0-105-gf02f. The hash rate increase due this optimized kernel has been about 7% only.

Thanks.

That is right in the MHs range I was getting with catalyst 14.9 driver ... use 14.7 RC3 or the bin provided by pallas and see what you get.

Here's my bin for 280x at 1170/150 getting 18.46MHs

Could not locate 14.7RC3 (I am on Linux), only 14.4, will try. The bin provided by pallas is for Hawaii (290), not for Tahiti (280), correct?

this is 14.9 (non-beta) for linux:

the hawaii binary should work on tahiti as well.

Any benefit for upgrading to 14.9?

using the old binary, made with 14.6, I noticed less power usage with 14.9.

I am getting better hash rates with this than with grs-sgminer (solo mining).  

R290  - 20.8 mh/s vs 18.3 mh/s with grs
R280x - 17.3 mh/s vs 14.6 mh/s with grs

I am not seeing much advantage to increase intensity above 20.

I am seeing that both cards are running hotter - using more power.  I have the 14.6 beta driver package installed.

However, I have two questions about what I am seeing.

1.  My R290s are set to 1100 for GPU speed, yet they are actually running under 1000.  I am seeing speeds of only 937.  auto gpu is disabled.  I increased powertune to 20 and the gpu speed increased slightly but not to the speed setting of 1100. Can anyone explain this?  

2.  I set the memory speeds on the R290s to 150.  With grs-sgminer I don't have to, they run at that speed simply because the memory is not used.  With this software, the memory on the R290s runs are 1250 and I cannot change that.  On the R280X, the memory is running at 1500 and I cannot lower it no matter what I set it to.  Can anyone explain this?

BTW, I was using the 13.12 driver package before and I could not get the hash rates that I am getting with the newer drivers.  The best I could get out of the R290s was about 13.8 mh/s.  With grs-sgminer and the 13.12 drivers I was getting 18.3 mh/s.

 https://mega.co.nz/#!pNcTnCLA!dszQHHMsK9RQngPQtQKsvKvvGz8KNqhPSO8HWwZNxD4

Thanks! It's running stable, yielding 17.5 MHs for my 280x at 1129/1000 (could not lower the ram speed below that) and the 14.4 Catalyst drivers.

[zgor]

this is 14.9 (non-beta) for linux:

Plan on trying it out.

the hawaii binary should work on tahiti as well.

Indeed it runs, but gives no MH increase :-(   Is it 64bits vs 32bits of the one provided by utahjohn?

Mine 64bit windows 14.7RC3 specifically compiled for 280x

Let me know if 14.9 with compiled (14.7) bin helps power consumption if you test it.

Also see https://bitcointalk.org/index.php?topic=779598.msg9043545#msg9043545 about forcing lower mem clock by vbios mod
Always keep a backup copy of original vbios for each specific card if you need to reflash back to normal for resale ...
If you can't get linux tools to mod the vbios, PM me for options.
Also note that vbios is card mfr specific, so I can't just give a .ROM for Powercolor card and have it work on a different card ...

1. High ram clock = lower Max core clock
2. If on Linux try:

Let me know if 14.9 with compiled (14.7) bin helps power consumption if you test it.

With your .bin, and 14.9, the power consumption appear very slightly higher, but within 1%, and the hashrate is up about 0.6%.

I'll stick with 14.7 then (I run other algos's also and have need to compile bin's).

http://epixoip.github.io/od6config/

I should have noted I am running Windows 7 64 bit.  I am trying to lower the RAM speed but it is not budging no matter what settings I try.  Likewise the GPU core clock is staying under 1000.

I do not have this problem with grs-sgminer miner. 

Even so, this package is giving me a higher hash rate than grs-sgminer so I will stay with it.

your gpu freq. fluct. is caused by driver power limit function.
just try to reduce gpu voltage - may be 2-3 steps backward...

That sound like a total line of crap to me.
