[Dev] NeoScrypt GPU Miner - Public Beta Test
-
Hi,
can some of the developers comment to this:
https://forum.feathercoin.com/index.php?/topic/7934-error-61-clcreatebuffer-padbuffer8/#entry68753
???
Thanks in advance,
cu
(Maybe I am simply to dumb …)

Has anyone compiled https://github.com/vehre/neo-gpuminer from source on Linux and successfully mined PXC or FTC on the testnet? All I get are hw errors, with any settings I’ve tried. Specifying no options to cgminer beyond a stratum connection and user/pass, or using even a bare minimum of -I 12 -w 32 -g 2 doesn’t help. I’m on 14.6 catalyst drivers with APP SDK 2.9.
I’m happy to provide any additional logs/info/settings or help troubleshoot if anyone has any suggestions.
The bare minimum would be -I 8 -w 128 and -g 1
I am mining PXC on the life net and have no problems yet. FTC is not yet on neoscrypt therefore mining on testnet is ok and should work, although I haven’t tested.

I started on 14.6 catalyst drivers (APP SDK 2.9), and then upgraded to 14.9 after it wasn’t working on v14.6.
I’m happy to provide any additional logs/info/settings or help troubleshoot if anyone has any suggestions.
You gotta start on 13.xx drivers or all you will get is hw errors with 3.7.7b… If you use the 14.xx drivers you need to use the bins created by 13.xx.
Use a driver cleaner to get rid of all of the 14.xx drivers.
In the cgminer folder, dump all the binfiles created by the 14.xx drivers.
Install 13.xx drivers, try out lots of settings, and save the bin files. (write down the settings you used on 13.xx so you can use them again in 14.xx)
Install 14.xx drivers, try out the settings you used on 13.xx so you use the 13.xx binfiles.
Any new settings that you try to use in 14.xx that you don’t have a 13.xx bin for will get nothing but hw errors.

Using -I 8 -w 128 -g 1 on PXC, I still only see HW errors.
Ah, that explains a lot, thanks. Unfortunately, it seems like a fairly large barrier to entry as far as getting an average miner interested in mining neoscrypt.
I’ll give that a try and report back.
On a related note, are there any plans to get neoscrypt support built into something more modern like sgminer v5?
Yeah, that’s only to get the optomized settings out of the software that we have… At some point whatever is causing that issue will get found and corrected, and things will get easier. :)
-
It’s very confusing to find how to get neoscrypt mining going, and where to post problems. There is no one description of where things are and generally how to do them and confilicting posts. (posted this in the mining thread by mistake, last night)
Its pretty much like the thread title says, its a open beta test at the moment for reporting problems and errors found.
I’m sure once more bugs are worked out and a more stable version is released there will be a updated page for
download and more info on how to setup and run the miner software which should fall pretty much in the norm for
usage/setup in a final release versions.
Edit: I’ll be testing a 2nd rig with 2x R9 270x in a little while and will report back on my findings with drivers on that 2nd rig later this morning.
I’ll also try working with the rig with the 2x6950 unlocked to 6970’s if I can squeeze in enough time for it as well.

The basic idea was that at least CPUminer and GPUminer to be available before Feathercoin could move over to neoscrypt. With the large user base, miners and pools needed to have those basic facilities available. It was very “brave” of Ghostlander to put Phoenixcoin on neoscript when only CPU mining was available.
The work we (Feathercoin) and others have sponsored and got done is the basic minimum. It should be more trivial to take that work and apply it to other software miners, like sgminer, now the basics are done.
One important action would be to get the neoscript cgminer version “Upstream” so it downloadable from Github source, for other coins to use and make it simpler to find and download.

Could all support issues please be raised in the support section and ‘best answer’ selected when resolved.

What would be the best config for a GTX 970?
I’m getting 150 KH/S using this right now, but not sure if I can do better (using 3.7.7b)
setx DISPLAY 0
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --neoscrypt -I 14 -g 1Also those settings really choke my pc, slows down. Not sure if I can change any setting to fix that.
Thanks :)

You should give -I 12 -w 64 -g 1 and -g 2 a try -I 13 may work ok as well.
-I 14 here made the OS some what lagged and the gain wasn’t worth the loss of the use of the computer for me.
but I do other things other than mine with my computers.
Edit: BTW nice to see someone unlocked this thread, lots of good info here and once it goes inactive that will be lost in the abyss of dead threads.
could just move it to the support section if its causing problems where its at. Use to be a ABIT motherboard forum admin/mod back in the day. ;-)

Yeah. The concern is that anyone with an issue has to sift through pages to find a similar issue. I’d encourage people to raise a thread in support if they are having difficulties with an issue but this thread can provide a broader overall look at progress.
The hope is we can use support as a library of issues and their solutions.
I might split the odd post out from time to time if they are clear support cases as it’s easier for us to track resolved issues this way.

Thanks :) I used those settings I now get 140 KH but my computer is usable. I guess the GTX 970 max is 140-150 then
What does the - g setting mean? Should I use 1 or 2. and is -w 64 the best for me?
PS: What is the max -I can go up to, i assume its intensity, if I try a higher value like 15 or 16 do i risk damaging my card

Here is a good read to help you understand what each do, with that said there are no one perfect user setting,
for your best results you will have to experiment with each to find what works best for you and your hardware.
Edit: NeoScrypt for GPU and CPU miners are still in the works so for now you can expect to use lower settings
for best results, as the miner software gets more optimized down the road you may be able to use higher intensity**.**
-
Thanks :)
that file says '-thread-concurrency,******but when i try that it says unrecognized **
what is the way to set concurrency in this neo miner?
-
Please add support for old cards, 5800 6800 6900 series. Please!
-
Best settings (140 KH)
setx DISPLAY 0
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --neoscrypt -I 13 -w 32 -g 1
I find w 32 is best for gtx970, I just can’t set a thread concurrency as it makes it shut down, but i dont know if thats important, maybe cause its nvidia
NOTE: I have tried I value of 15 and got 165 kh, so it can go higher, just that the computer goes very slow

Will the latest version always be attached to the OP :) I don’t know how to compile (and don’t have linux), so I appreciate that

op has not the latest…
it has 3.7.7b current is 3.7.7c
windows miner compiled by me, 3.7.7c:
-
3.7.7c still has miserable performance on HD 6950. Can someone please add support for VLIW cards? I would be happy to test or provide log files.
Thanks.

Hrmm…
Seams what we need to try focus on is support for additional cards…
This is all open source guys, if someone knows anyone who might be able to help, please do not hesitate to contact them and me and I’ll try get some collaboration going with other devs who work with us.

u may know this guy called wolf on btc forum,
he seems to be quite good with kernels.
