[Dev] NeoScrypt GPU Miner - Public Beta Test
-
What did you expect? The kernel in the regular cgminer has not gotten any optimizations. Unfortunately most of the time was spend in figuring the changes in the protocol.
To get more out of the HD5870 try to play with the worksize -w and intensity -I
I suggest starting with -w 128 and -I 8 and than increasing -I in steps of one untill the memory can’t get allocated anymore
and retry this series with -w 256 and -w 512, then choose the best result for your card and system.Allways note down the number of hashes you get while running for an equal number of minutes.
I’ve made enough research before posting. 6KH/s is as much as it can do with --thread-concurrency 8192 -w 128 -I 13. ATI/AMD cards of their VLIW5/VLIW4 architectures require more optimisation than newer GCN or NVIDIA CUDA cores. They also need much higher intensities for the best performance.
An older and weaker 9800GTX which has never been any good to mining produces 3.5KH/s without HW errors (-I 11) and 4.7KH/s with them (-I 12). HD5870 vs. 9800GTX under Scrypt is 400KH/s vs. 50KH/s.

Well levelling the playing field is a good thing it means it can be more “fair” and potentially cheaper to mine?

Just compiled 3.7.7b and I’ve only been running for a few minutes but it looks to be just ever so faster than the previous versions for me.
Will let it tun for a while and report back
-
folks, can you upload a precompiled 3.7.7b ?

I’ve adapted bfgminers windows build.txt to compile the gpu miner for AMD cards.
Somebody please check my sloppy work and add what i surely forgot, it would be nice if somebody could add the instructions for Nvidia.

Also a link to version 3.7.7b that i compiled with these instructions
https://mega.co.nz/#!FcVTEQyQ!ozPVAzZJCIGm7-nbqB3E4y1xudHI62g6YVfF_YI_GUI
Copy libglib-2.0-0.dll from C:\Program Files\GTK2-Runtime\bin to C:\MinGW\bin
is this missing file intl.dll? -did not help
edit: reinstalled mingw and gpu mining is now found
compiled and hashing!
i used CFLAGS=“-O2 -msse2” instead of -02 -g
file size 519KB instead of 1436KB, what is changed? working fine…
leaving 280x/3.7.7b working with -g 2 -w 24 -I 13

tmuir12, Chrome doesnt even let me download it… :D

Don’t know why, maybe its a Chrome thing.
I use Firefox and just opened up IE and it works for that too.
Ijust realised I left a space in the filename, maybe Chrome doesn’t like that, so I have fixed it.
I’ve updated the link above, but here it is again

says zlib1.dll is missing

I am so ready for the 25th. You guys should really edit the first post of this topic so people can find the right download on the first page.
says zlib1.dll is missing
The cgminer 1.75 zip file from the first page don’t have that driver. You don’t want that version anyways. 1.7.7b is more stable and has higher performance.
Also a link to version 3.7.7b that i compiled with these instructions
https://mega.co.nz/#!FcVTEQyQ!ozPVAzZJCIGm7-nbqB3E4y1xudHI62g6YVfF_YI_GUI
I am running that version with my bat file:
setx DISPLAY 0
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --neoscrypt -I 11 -w32 -g 2 -o stratum+tcp://atlas.phoenixcoin.org:10554 -u
-p x
I am getting 40.5khash/sec on a GeForce GTX 560.

The current version of neo-gpu miner does not work with AMD drivers higher than 13.12.
I found that when i add the amd opencl files from the 13.12 driver pack to the cgminer directory that it does work with the 14.xx drivers.
But a little slower…
If anybody is interested … link to neo-gpuminer 3.7.7b that works on 14.xx AMD drivers
https://mega.co.nz/#!lVUURaAK!epWoeHGYXiKFXlAJ2VvG9LwuUBh-4bi1TNS-JXjgxLQ
Using setx display, gpu, etc does not add anything to performance, just leave it out.
I get 90kh/s on an amd 280x with these settings
cgminer.exe --neoscrypt -I 14 -w 48 -o stratum+tcp://prometheus.phoenixcoin.org:10554 -u
-p x

same settings 3.7.7b, -g 2 -w 48 -I 14, 13.xx drivers
280x hynix= 100khs
have u tried bin files crossed? freshalgo did best when 14.xx created bin at 13.x drivers

Sorrry
Here it is

I went from 290 to 380-90khs with cisahasa’s config last night!

miner stable overnight without any -T options, average 98khs/gpu

folks can we do a quick wrap up of what we have had so far?
this is a track record of my progress with the gpu miner
1.
2.
3.The last one is a 4 gpu config -w 48 -I 14 >90 khs/gpu cgminer 3.7.7b
do you think it is good to go already?

hi guys
i just hooked up a amd 6950 and i downloaded the cgminer, but when i run it, it just stops working and crashes. I’m using windows 8 64bit. and just updated my drivers to the latest. Could you know why this may be happening?
-
If you are using catalyst 14.something it won’t work.
Don’t go higher than 13.12
But there may also be win8 issues as I know of atleast one other person running win 8 that is having issues
-
my 6950 is really slow… its like just 4kH
@Yusuf, you may want to try a higher -w value…

aah tmuir12, thanks. i think i was using the 14.xx catalyst from above. could you please link me to the pre compiled cgminer for 13.12?
thanks again!
