[Dev] NeoScrypt GPU Miner - Public Beta Test

Alpha Wolf

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

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.

Tested GTX480 with 3.7.8 and 3.7.7c 1kh/s difference in the speed between the two.

326.80 driver 27kh/s but driver crash when closed/shut down

344.60 driver 25kh/s no crash of drive so far when cgminer is closed.

So GTX480 is 2 to 3KH/s slower than 760GTX and 1Kh/s slower than 660GTX with either cgminers versions.

All the same settings was used in all test -I 10 -w 16

My fleet speed at the moment:-)

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.

Okay, this has become a long thread and I think there’s need for a step-by-step recap on what to do with what to achieve these results ?

Like this (for Linux systems, don’t have M$ so can’t speak for that):

install Xubuntu 12.04LTS
install AMD driver version ?
install ADL_SDK version ?
git clone sgminer/cgminer/neominer ?
compile and install miner
adjust miners config based on GPU model

Can we fill in the ? with links and versions ?

Cheers,

Paul

can anyone please let me know the settings for r9 280x

i am getting 75kh/s on both 13.12 and 14.6 drivers with below settings…

-I 16 -w 72 -g 1…

i tried generating bin files on 13.12 and then running them on 14.6 but getting the same hash rate.

can i try 13.12 bin files on 14.9 as suggested by some ???

or its necessary to have bin files on 13.11 and run 14.9 ???

Try -I 14 -w 48 -g 2

You should get higher hashes with that. If you can, push the intensity up to 15.

If you are using cgminer 3.7.8 or the sgminer5 that Wolf0 posted in this thread a couple pages back, you will get the best performance from 14.9.x and up. Wolf0 fixed the kernel just enough to make 14.9.x work with our miners, so the days of having the generate 13.12 bins and using those in 14.9.x are long gone :)

God damn AMD 78xx Pitcairns are such a PITA to mine with. One day they mine just fine with your settings. The next day they act unstable and decide to start randomly crashing your GPU drivers. I wish my 7870 was a Tahiti. Would be much easier.

For those with old Radeon cards. This is my current OpenCL kernel: neoscrypt_vliw.cl

It is optimised to some extent for VLIW4/VLIW5. I get 17.5KH/s with it on a HD6970. That’s not much, but still better than 6KH/s with the default kernel.

Congrats - not a bad chacha for 6xxx. Your salsa though… needs work.

Okay, here you go (NSFW): https://ottrbutt.com/miner/neoscryptwolf-11042014.png

As you can see, every card is around mid-70C or below, except that 270X with the dead fan. What you don’t see is that all of them have a decent sized voltage bump, except that 270X, which is slightly undervolted to compensate for its lack of cooling. So, even at this hashrate, the cards are running quite cool - too cool, as my room is rather warm (probably from all three desktops with high end GPUs…) - so I need to trade off some of the memory usage for extra computations. Compute power is likely still plentiful, unused because of memory access times.

Here’s my 7950 doing 150Kh/s. Fairly Safe For Work. (In Soviet Russia, You maul Bear! Then if you’re lucky, she mauls you back) I could use a suggestion for a good overclocking bios though. Been playing around boosting a few to 1.3v and I just ran across The Stilt’s mods the other day but haven’t had much luck with them either. As you can see, temperatures are absolutely no problem. Stays under 70 even when scrypt-hashing full load, full crank. Too many variations! Can’t spend days freezing and rebooting. It’s a Gigabyte, part 113-HD685ZNF63.SB, Hynix mem of course. My best so far is around 1260/1740. Would love to hit 1300/1800.

Gentlemen, is 3.7.7c the latest version? I don’t have linux unfortunately so can’t compile, and I probably don’t have the knowledge to do so :(. Is there a place I can go to find the latest version in compiled/windows format

SS2006

i assume this is the newest version: http://cryptomining-blog.com/3715-new-cgminer-3-7-8-with-improved-neoscrypt-performance/

unfortunately it took a step backwards for nvidia cards (slower), but its meant for AMD so if that is better there, then good!

The download link that this blog provides is hosted by itself… No sigs etc…

Not 100% sure if I would trust that download link.

Wolf0 has a nice windows compile right here signed and all.

Okay, done. I’m pretty sure it works, but haven’t tested on a Windows installation. This is a zip of my kernel, slighly modified for SGMiner, as well as all the other kernels included on the github’s develop branch, and a Win64 binary. Static compile, no DLLs, just like my standard SGMiner builds on Litecointalk. Also GPG signed, like my standard builds. Someone please test for me and ensure it works.

And of course, GPG sigs for those that check them (you should be): https://ottrbutt.com/sgminer/neoscrypt/sgminer5-neoscrypt-11-02-2014.zip.sig

It’s scalar now. I’m not impressed by one found in old Scrypt kernels. Can write a better one probably. It isn’t a bottleneck anyway for these cards. When I replaced ChaCha with this one, it went from something like 12KH/s to 14KH/s. Loop unrolling delivered more alone.

BTW, it runs reasonably good with old AMD drivers and OpenCL compilers. HD5870 on Windows XP with 12.4 drivers went from 2.5KH/s to 10KH/s. Hell yeah, a 4x increase. Don’t try to use this kernel for NVIDIA. It fails to compile the vectorised ChaCha code.

How it use? Which miner?

Rename and put into any miner with the NeoScrypt support. Tested on cgminer v3.7.7, works fine.

Working great here for me with a couple 6950 unlocked to 6970. Went from 5kh/s to 16.5kh/s with

use of only -12 -w 64 -g 2 also works with 3.7.7c and 3.7.8 all I did was backup neoscrypt140909.cl then

delete it and remane your file to neoscrypt140909.cl to replace it, then backed up then deleted all .bin files

letting it make new .bins and bam I was off to the races. :)

Thank you!

Now I don’t mind running them, before I wouldn’t even use them to mine with.

I am right that I can not do anything with my GeForce 7600GS?

i think there is some error…

__attribute__((reqd_work_group_size(WORKGROUPSIZE, 1, 1)))

it should be? ???

WORKSIZE is only for the newer SGMiner.
