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

Gee

Zpool is an autoswitching pool. NSGminer doesn't like this. It works best with a single chain.

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.

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.

Some pascal love ?

No surrender, no retreat, no regret.

Got two used R9 280X for cheap. Both with the Elpida/Micron memory (EDW2032BBBG). No surprise they only do about 455KH/s at their default clocks, 1000MHz core / 1500MHz memory. That's because of shitty timings set in the BIOS by greedy and clueless OEMs. Those Radeons with the Hynix AFR memory (H5GQ2H24AFR) produce about 480KH/s at the same clock speeds thanks to AMD providing better tuned memory straps. So I hacked their BIOSes to set correct memory timings. Hash rate improved to 495KH/s at the same clocks or 510KH/s with a core overclock to 1050MHz. +9% performance on memory timings alone, definitely not bad.

Is the work with Gridseed G-Blade?

Gridseed Blade only for scrypt algo, which is different with NeoScrypt.
You can not mine neo with scrypt asic mate.

I have used nsgminer 0.9.2 from git and have one big problem - when I press Q (Quit) my system hangs .
this thing occurs at various intensity . I used AMD R9 380
please help

What's your OS and drivers? Run with --no-nvml if you have any NVIDIA GPU drivers installed even if there is no NVIDIA card in use currently.

I am used OS Ubuntu 14.04 and Win7. On Win7 I tried use various drivers but system hangs ((

Try to reduce GPU clocks. NeoScrypt stresses GPUs more than other popular algorithms. After all, why need you press Quit?

GPU clocks are standard. may be I must put lower intensity (now it is 15)?
I need shutdown my computer for technical service.

So I have two GTX 980's and they're both only mining at about 30KH/s, clearly I'm doing something wrong. I have nothing fancy in the config, just --neoscrypt then my server info. Any help? Nothing weird showing up either, just standard "accepted.." I'm running on the latest nvidia drivers because I like to game on this rig as well, hopefully that's not an issue (although I wouldn't mind a small downgrade if it's a huge difference in hashrate) I'm running on Windows 10 x64 if that makes any difference, and here's a screenshot of the miner: https://i.imgur.com/HUmfm7c.png

It's running low intensity probably. Add "-g 1 -w 64 -I 16" to the config. Every time you use this desktop for something other than mining, reduce intensity to something like 10 and set it back again without restarting the miner. You may need to disable SLI for higher performance.

You can also choose my CCminer NeoScrypt fork, though it's no good if you use this desktop every day. Makes it hardly responsive to mouse, keyboard, etc.

You are using the wrong fork:

https://github.com/sp-hash/ccminer/releases/

run with ccminer -a neoscrypt --benchmark

Added my fork of CCminer to the OP. NVIDIA Maxwell only, CUDA 6.5 or newer. Works with Windows XP or newer and Linux of course.
