Yea, The miner was only reporting 27-30MH/s but pool side it was always more.

@nimy

You have to download the source from github and extract the binary-kernel, and Kernel folders to GG pre4 folder then I use the settings provided by OP. You should be able to get 28 - 29.

Note: I have been tweaking my cards bioses for quite some time now to achieve the speeds I have. I have been monitoring the timings thread to learn and nerdralph has a tool that got me a 1MH boost to my old mem shift timings. (I don't share my bioses as I believe everyone can take the time to learn if they want more.)
Thanks.. now i got 28mhs.. worth it.. next need to optimize my memory timings..

With newer kernel HW error rate has increased a bit, Using your asm binary kernel reports 29.5 stable with less hw errors. When  I delete bins and ethash-new.cl generates binary kernel rate reaches 30.1 but with about 3.66 hw errors per minute average, last one was with 2.33 average.

How to minimize the hardware error? Got a lot HW.. using default intensity from github.

i just uploaded a new pre-release with Ethash assembly kernels for all GCN1/GCN3 devices, including Fury, Fury X, and Nano:

https://github.com/zawawawa/gatelessgate/releases/tag/v0.1.3-pre5

The default settings in .bat/.sh files are improved as well.
As always, I really appreciate your donations and feedback. Enjoy!

zawawa, thanks! What about nicehash ethereum comatibility?
And what is the optimal parameters for 280X and 270X?

On Claymore Dual miner 8.1 I got 15.6M on 280X and 11.6M оn 270X with -etha 1,1 parameter (auto is -etha 0,0 wich is slower on my cards).
On sgminer-gm 5.5.5-gm-nicehash-8 with gg 0.1.3pre5 ethash-new kernel and bins I got only 15M on 280X and 10.7M on 270X.
Even with 1% fee Claymore is quicker on tahiti and pitcairn... Or I do wrong something?

Well, I don't maintain sgminer-gm-nicehash, so I have no idea.

gg miner is not work on nicehash. All shares rejecting. Because of it I use sg-miner with gg kernels and bins.
Please add support for nicehash ethereum.

p.s.  There's also some easy optimizations to do with instruction reordering (though they might not make much difference in performance).  For example:
Code:
/*d11c6a3e 01a9013c*/ v_addc_u32      v62, vcc, v60, 0, vcc
/*2a7e62b2         */ v_xor_b32       v63, 50, v49
/*dc5c0000 4000003d*/ flat_load_dwordx4 v[64:67], v[61:62] slc glc
/*dc5c0000 3b00003b*/ flat_load_dwordx4 v[59:62], v[59:60] slc glc
/*bf8c0171         */ s_waitcnt       vmcnt(1) & lgkmcnt(1)

The v_xor_b32 can be moved to after the flat_load_dwordx4.


That's a good catch. I was actually thinking about automating this kind of instruction reordering.
My compiler driver rewrites the output of LLVM/Clang, so it shouldn't be that difficult.
I really want to combine this feature with register usage analysis.

One thing I've wanted to do but never had enough free time for is an in-place keccak implementation (see section 2.5).
http://keccak.noekeon.org/Keccak-implementation-3.2.pdf

It won't help much for pure ethash mining performance as memory bandwidth is the limiting factor, but it could free up a lot of VALU time for dual mining.  And for pure ethash, although it won't do much for performance, it should help reduce power consumption.
And speaking of power consumption, I have an idea that could significantly cut power use in memory-hungry algos like ETH, XMR, & ZEC.  In order to have any hope of getting it to work, I have to first figure out how the active CU masks in the driver work...

These Hardware errors do have any impact on perfomance? or i can just ignore them?

I can not start it, it always fails, someone could post the configuration of your bat file? I have tried it on nanopool, and even on pool.sexy, but keeps giving error

I would love to implement dual-mining, but I found sgminer's back-end too limiting for that.
I really would like to implement my own back-end in Clojure one day, but that's a really long shot...

sgminer/gg has no support for old stratum and getwork protocol. To connect to those pools use eth stratum proxy from dwarfpool.

I think you should use --gpu-platform 1 for gpu mining..
