With default setting from your .bat, on polaris cards I'm very close to claymore on eth, but my 290x is almost 3mh behind.

some additional info:
R9 390 with gateless gate & ethash-new = 31.9-32 mhs. xI of 1920, worksize 192, 2 threads
This is the same or better performance I get from Claymore. I am getting slowly increasing HW errors, but no rejected shares or issues shown at the pool side.
This card has +6.5% core clock and 1550 mhz memclock. Drivers are 17.3.2 on Windows 8.1.

zawawa Does this do what CM 12.4 does yet for ZEC if so , could you give me some tips on how to hit 306 Sol on a 480 8gb at stock setting ? ... CM does that on my 480 8gb at stock no molded bios .. but This matches CM's eth miner ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) at stock setting nice work ..... so I'm gonna start using it when I ETH mine ... and ask to have it added to http://ethosdistro.com/

On latest drivers, the eth-new works far better them 16.x or lower

2 threads dont change too much thing at all...only hardware errors
Just use Xi - 512 and gpu threads - 1
avoid a lot of hw errors

Sgminer has always been faster than claymore on my 290x on Linux/fglrx. It's on Polaris where it is slightly behind.

Zawawa didnt even touch the kernel,and it is fast as claymore on my 390, im sure if he give a week on it, it ill beat claymore

i'm getting about 2 mh/s less than genoil miner over 4 cards.
Genoil's gives me about 90 mh/s on 4 rx 480 stock no bios mods this one says about 88, maybe a bit less.

I just pushed to the repo an optimized GCN assembly version of ethash-new.cl for RX 470/480. Each card should get a 1Mh/s boost with it. If this actually works, then I will extend its support to GCN1/GCN3 devices. (I sold all of my GCN2 cards a while back...)

Excellent, but what settings are best to achieve those speeds? I have tried 1 gpu thread WS=192, xI: 1024 but speed is lower

That's not optimized - you flipped the SLC and GLC bits, which will likely make it a tad SLOWER; it did when I tried that. That's what I thought as well, but the miner was actually running faster, though. Let me double check...

I run the same experiment one more time, and I confirmed that ethash-new.cl actually runs faster with the GLC and SLC bits on. With the GLC and SLC bits on: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FtrgEscE.png&t=663&c=zFkQk_vVXMm_ZA) With the GLC and SLC bits off: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FTrr88nH.png&t=663&c=T-xCGBzUipoMQA) The .bat file: @echo off set GPU_FORCE_64BIT_PTR 0 set GPU_MAX_HEAP_SIZE 100 set GPU_USE_SYNC_OBJECTS 1 set GPU_MAX_ALLOC_PERCENT 100 set GPU_SINGLE_ALLOC_PERCENT 100 gatelessgate.exe --gpu-platform 1 -k ethash-new -o stratum+tcp://eu1.ethermine.org:4444 -u 0x91fa32e00b0f365d629fb625182a83fed61f0642.gatelessgate -p x --xintensity 4620 --worksize 192 --gpu-threads 2 --no-extranonce pause I ran this experiment on Windows 10 with stock RX 480 and AMD Crimson Software 16.9.2 as usual. @laik2 It would be great if you could try the above settings as well. I am puzzled by the results myself...

Tried default config, xI 2048, xI 1024, gpu-threads 2,1...every time the windows crashed, I'm sorry but I can't test due to unknown reason...I don't like windows environment at all. On linux it's doing ~ claymore.

That's not optimized - you flipped the SLC and GLC bits, which will likely make it a tad SLOWER; it did when I tried that. I was expecting just SLC (bypass L2) to help, though I recall Wolf's comments about GLC (bypass L1) actually helping. I'd even expect GLC to hurt performance if you weren't very careful to ensure data was read in 64-byte chunks. p.s. There's also some easy optimizations to do with instruction reordering (though they might not make much difference in performance). For example: /*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.

I probably wouldn't even bother with Southern Islands; no flat_ instructions. It should be reasonably easy to write a single kernel for Sea Islands and later, with the main differences being for the ABI changes for kernel parameter passing.

Just cloned the repo to do a linux build then noticed the autotools requirement. Ugh. I much prefer it when developers run autoreconf, and check the configure script into the repo. Then to build it's just the usual ./configure;make

I will probably switch to CMake + ninja sooner than later. This whole autotools thing is too archaic to my taste.
