[Dev] NeoScrypt GPU Miner - Public Beta Test
-
So this time, I just created simple opencl initialization and exection code into cpuminer, orginally neoscrypt cpuminer, then got it working.
(I like the neoscrypt cpuminer code, simple, easy to understand and maintain.)
(Sorry for the neoscrypt code, I removed lots of unnecessary code, to my understanding, compare to the original one.)If the unnecessary code you’re talking about is SHA-256 and BLAKE-256, these parts may be removed. SHA-256 is for backward compatibility with Scrypt. BLAKE-256 was for testing purposes until FastKDF and BLAKE2s were implemented. Good luck with your coding. CPUminer is also a work in progress.

That looks quite fine. Please retry mining setting intensity significantly lower, I.e. to 8 or even less (-i 8)
-
Have the same problem, compiles fine but get no accepted shares.
I need lo lower intensity to 6 to get accepted and the i get 2.5kh/s or so
with 3.7.5 i get about 50 kh/s with -I 11
-
Hi, anybody having the problem of 3.7.5 stops working after 3-4 hours? On win7 x64
-
Hi raintowers,
can you run the miner with -TDP and log the output to a file? Send me the about last 1000 lines of the file, please.
-
Could you open an issue at https://github.com/vehre/neo-gpuminer/issues for every issue that occurs?
This helps to keep track about problems, when they occur, and if they have been processed, resolved and when.
Thanks for helping.
-
OK I’ve done it. I’m a Network Admin but been out of it for a long time. I have some tech skills but not much on the programming side. Will help as much as I can.
-
Sorry for being imprecise. I am interested in the about last 1000 lines of the log, when the miner aborts on its own after running for 3-5 hours.
Please add those lines to the tickets on github.
-
Well that’s interesting. I’ve been running since yesterday with the -TDP options and it hasn’t frozen once… Still going. I wonder what showing verbose output has to do with it? I’ll keep you updated.
-
Yes I also can’t run the 3.7.6x (only get HW errors) but 3.7.5 is fine.
I’m running windows 7 64bit with AMD HD7800 deries card, can’t find the receiept with the exact moel on it at the moment, what are you running.
-
No still only HW errors for me on 3.7.6 unfortunately
I will be offline for the next 6 days after tonight, so won’t be able to provide any otehr feedback until most likely next weekend
-
Deleted the bin file, but mine is called neoscrypt140909Pitcairngtc256w256l4
Also tried replacing the cl file with my version from when I compiled 3.7.5, but it made no difference

Got a set of 7950’s running great at 75Kh/s. Seems that with these GPU’s the lower the -w value the better. GPU 3 is an R9 290 which I’ve only gotten to hash around 78Kh/s so far (-w 24, --thread-concurrency 9856 to prevent failing on launch) Still trying to figure out some optimal settings for it. With all 4 gpu’s running I’m hashing 303Kh/s @ 750 watts.
Here’s what I’m using:
cgminer.exe --neoscrypt -I 13 -w 32

I was always under the impression that the 280X had comparable performance with the regular 290 - which in the case of your results would be true. As far as power consumption, I’ve had great luck with MSI Afterburner undervolting my 290’s to save power. If you haven’t tried it yet, I highly recommend playing with it to see if you can find a good stable lower voltage. I run my Hynix ram 290’s with -62 for the voltage. It really depends on which type of memory you have in yours. I haven’t had very good luck with Elpida ram and undervolting.

Maybe try going back to an older CC version. My 2 rigs have 13.11 and 13.12 respectively - however, I am running Win 7 64-bit, not Windows 8.1. Uninstall 14.4, then run theDDU software in safe mode to make sure you’ve cleaned up all the old crap. Install one of the older CC versions and for troubleshooting purposes you should also reset any OC tweaks you may have configured. You should also take a look at the .bin file that cgminer is creating and look at the “tc” setting. Sometimes having a thread-concurrency setting that is too high or low can cause a ton of HW errors. That’s my best guess anyway.
-
Bring the work back up to 24 now that you’re on 13.12 - I bet you’ll start hashing in the upper 70’s. On an entirely different note, my 290 rig seems to perform exactly the same with lower gpu clock and memory speeds. I’m using MSI Afterburner to underclock and undervolt everything. 947 clock, 1250 mem, and -100 core voltage. Dropped power consumption quite a bit while not affecting the hash rate at all.

my amd driver crashes when using -w 24 -I 12…
radeon 7990, driver 13.something, although getting nearly 140 khs
-
Currently getting about 80 kh/s with 3.7.6b, cl file from 3.7.5, *.bin generated with drivers 13.12. And currently running on 14.9
Sapphire 280x with settings
cgminer.exe --neoscrypt -I 13 -w 32 --thread-concurrency 8192
definitely something wrong with the *.cl file from 3.7.6b, no accepted shares unless i lower intensity to 6 but then no performance.

nope… the miner freezes here after a while :(
it starts off well and after five minutes this is what i get
or
what should i do?

I’ve been having the same problems with freezing. I use the -T option and it keeps running with -w 256 -I 11 --gpu-threads 2. We’ve been discussing options here https://github.com/vehre/neo-gpuminer/issues/3
