[Dev] NeoScrypt GPU Miner - Public Beta Test
-
Pretty much; also, a Hynix 280X does quite a bit better than Elpida - I believe I’m getting 290+ kh/s from it. As I decreased memory fetching, useless code, and other stuff that can cause the GPU to stall, I found running LESS threads per GPU began getting far better hashrates. With the stock miner, running more threads may help, because the more threads you’re running, the more the GPU can hide that it’s waiting on a memory access. The idea is this: if a compute unit has the resources, and is stalling on a memory access, the card can schedule another wavefront to run on the CU - this means you’re hashing even when waiting for memory.
EDIT:
I should also note that --gpu-threads is a REALLY stupid name, your GPU is running at least tens of thousands of threads, --gpu-threads means spawn x amount of threads on the CPU, each giving work to the GPU.
May I ask what queue, expiry, and scan-time settings you are using?

It’s really totally irrelevant, but I think queue is 0 in my config, scan-time is 5, and expiry I forget - maybe not set.

Getting 145kh/s with my 280x with sgminer 5 settings : sgminer.exe --algorithm neoscrypt -I 15 -w 48 -g 2 --no-submit-stale -o -p
That is 60kh/s faster than 3.7.7b and the same as with 3.7.8.
Thanks Wolf, your contribution is greatly appreciated.

Anyone except me having problems even getting sgminer started? It comes to the jansson line and then just dies. No binary created
Tried with as few settings as you can possibly use without no difference…
Oh and btw, great job Wolf0! Accidently opened your screenshot here at work and noticed your NSFW warning afterwards, LOL :D

Delete your sgminer folder and do a recursive clone - git clone --recursive.

Thank you. Just trying to increase WU/m.

Just in case some of you haven’t seen them before, my screenshots are NSFW.

Wolf0 , First thank you for great work .
I tested R 290x R290 and R280 but i can’t get more than 160kh for R280 and for R290, R290x 190kh/s
Can you please help more .
How you got this high hashrate !!?

You need to read the thread a bit more. He is using his own PRIVATE kernels. As long as he never releases his private kernels you will never get the same speeds as him. 190Kh/s for a 290x is pretty much the highest I have seen posted in this thread, so why would you need help? From the looks of it you are doing just fine without any help whatsoever. How about you tell us how you got a 290x at 190 Kh/s?

He probably has non-reference cards, or at least Hynix memory, on the 290x. I’ve gotten a TRI-X 290 card to 190kh/s (it has Hynix memory). My reference 290x are around 178kh/s max at the moment.
Elpida, I believe. My reference Sapphire, which is kind of a dog, does 270 - 280, while my non-ref Asus does like 310kh/s. I believe they’re both Elpida, because my Hynix 280X does over 290kh/s.

I got 200 kh/s on R290x refrence and 190kh/s on 290 refrence

Do you have any plan for publish new kernel ?

Not at the moment - however, I am considering fixing chacha and salsa for pre-GCN cards. Would even the playing field for people with 6xxx and below.

We would sincerely appreciate a fix for pre-GCN cards. I think people need to donate to you also for all the work you have done for us already, including outside of FTC. If it weren’t for you Wolf, we wouldn’t even have sgminer.

Well, salsa and chacha won’t be too difficult, but does a 6xxx card mine right now? At all? If not, then it may not be able to address global memory using unaligned addresses, and then it’d be a nightmare to fix.

6000 series cards do mine Neoscrypt, but they are very slow. My 6950, for example, will mine Neoscrypt at around 6-7 KH/s at best with the current kernel.

Got it on a box I can SSH to?

It’s a Windows box, but I should be able to get sshd installed via cygwin, other than that there’s RDP and VNC.

Did you find a fix for this as I’m having the same results with sgminer on OS W7 64bit?
3.7.8 works fine with my R9 270’s and I’m getting 60kh/s per card with it.
I even seen a little bump for my Nvidia cards with 3.7.8 with GTX760 & 660 cards, about 6 to 10 kh/s each.
3.7.8 didn’t seem to help my laptop 560m but that could be driver related since I have a newer driver on the laptop.

Evening chaps, finally got round to catching up with the crypto world. Think I’m missing something though… read through this thread and got the sgminer folder Wolf0 kindly posted. Just checking what settings y’all using for a 280x toxic and a xfx reference 6970?
-I 14 -g 2 -w 128 gives 74khs on the 280x and 6khs on the 6970. No special marks for me obviously, but any increase to the 150+ range would be appreciated. Also, I’m unsure as to how to specify different settings for different cards. I don’t want to do any over/underclocking, I’d just like some basic good settings. Also, I’m noob.
Kind regards,
T4

6xxx cards having a hard time due to their design. I’ll try to fix it when I have access to a test card.
