Just to let you guys know, it is entirely possible to improve the OpenCL kernel of this miner by eliminating scratchpad registers (register spills). I am currently getting 795KH/s, a 30% increase in speed, with a RX 480 and a heavily modified kernel. It is also possible to optimize the generated GCN code and make the kernel even faster.
I am currently focused on Ethereum mining because it is more profitable, but I might release my custom NeoScrypt kernel when I have a chance.

I don't see any reasons why the same kind of optimization cannot be done with Pascal. Ultimately Polaris is easier to tame because GCN is documented better than NVIDIA SASS and there is a pretty decent assembler for the former, but PTX should suffice for NeoScrypt, methinks. It all depends on profitability as far as I am concerned, and my current focus is on Polaris because I invested so much on RX 480. I was mining Feathercoin for a while with 290X's at 800Kh/s each when the price was good. I hope the coin picks up momentum again.

Guys, I am using NSGminer on zpool.ca but sometimes I get pool is sending mismatched block contents to us (0 is not 1-1) or other numbers. What does it mean? Can someone help me please? Thank you very much ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Gee Zpool is an autoswitching pool. NSGminer doesn't like this. It works best with a single chain.

It's definitely possible. There are 192 scratchpad regs for Tahiti. It's also important to keep the ISA size small enough to fit the GCN code caches. I have no RX 480 and cannot optimise for it right now. If you care to share your work, I'm sure some donations and thanks will go your way.

I just need to clarify myself a bit. The optimization I did for nsgminer was originally for GCN1/2 (7970/7990/290X) with a 30% gain in speed across the board, and I then recompiled the kernel with CodeXL for GCN4 (RX 480). I am pretty busy right now setting up a mining farm, but I may have time to clean up the code for a public release when things slow down.

This sounds awesome, i love FTC, will wait for your miner to come back in, i got a few RX 470 8GB up and ready.

Guys,if you have an rx 480 what's yours hashrate
Another questione,when i try to mine something i get a bsod and the errore is something like "mkatidag" what's this,the only algo that does not give me this error is daggerhashimoto
PS:my PSU is enough powerfull

Your cards are overclocked too much. The Ethereum algo is less power hungry. GPUs are limited by their memory bandwidth. That's why dual miners work there by running memory and computation expensive algos concurrently. NeoScrypt is both memory and computation expensive.

In C\system32\drivers find atimkdag.sys and rename it to atimkdag.sys.old 2.reboot 3.Now if you try to mine you can't,rename atikdag.sys.old to atimkdag.sys 4.reboot Now you Can freely mine. I don't if i'll help you but i think you can try,remember when you rename atimkdag.sys and reboot your GPU wont be seen by the system so if you have not an integraded GPU you Will not see the desktop,i used the integraded GPU of my cpu

If you cannot connect to a pool, try another one. If your mining rig BSODs or produces HW errors, try to downgrade your drivers. I use Catalyst 14.6 beta / 14.7 RC3 mostly, though 15.7.1 also seems fine. 16.x are messy, so they're a matter of trial and error.

Can someone share good setting for 7950 and 270x ? I get weird results. 370Kh for 7950 and 290 for 270x (stock) But from time to time speed goes down and have to restart the miner testing orbit@TBF
Also 10-15% of "share is above target"
