Windows 10 64bit NSGminer 0.9.3 RX570 and a HD Sapphire 7970
-
Hello I’m not new to mining but I am having trouble setting up my two cards to work at its best.
@ghostlander
Your update is amazing thank you for your hard work. It has increased my HD Sapphire 7970 close to 500KH\s
Settings --> g=1 I=16 w-128 gpuE=1100 gpuM=1550 with next to non rejects.
Unless you know how to push more. Let me know.The thing is I’m having problems utilizing my: "RX 570 Sapphire Nitro+ 8gb "
Right now the setting are:
g=1 I=16 w-128 gpuE=1380 gpuM=2100 Hash is 410-430 KH/s
I’m still trying to figure out the best setting to get the best hashrate.On your old version (0.9.2) it pushes out 430-440 KH/s when the settings are:
g=1 I=16 w-256 gpuE=1380 gpuM=2100
When trying these same setting in the new version I get an error, it looks like this:
err : KHs / 0.0 : KHs / Avg 0.0 KHs
So I had to change the Work to 128. As seen above.I think it should be pushing out more. I was hoping around 600 KH/s on average. Let me know if I’m missing something.
Reason for asking is that i like testing programs and mining with all kinds of newer cards. (I’m a Software developer still getting use to mining)
Let me know or anyone else can help also when you all have time. Thank you for helping. -
-w 256 is no longer working because the v8 kernel uses more local memory than v7. It takes 32Kb for a work group of 128 threads and that’s the hardware limit for AMD GPUs.
500KH/s for your Sapphire HD7970 is expected. You can get more by reducing memory timings, though it requires some BIOS hacking skills. You can also set FASTKDF_COMPACT to 1 in the kernel to squeeze out a bit more performance. Tahiti and Hawaii like it with the older drivers.
The story of the RX series is sad because quality of the AMD OpenCL compiler has degraded greatly over the previous 3 years. It used to produce very compact kernel binaries back in 2014. Nowadays it spits out bloated junk 5x in size. I get 500 to 550KH/s for a reference RX 480 with their amdgpu-pro drivers.

Hi and welcome to the forum

@ghostlander Thank you for the information. I just have one more question just more of a trial and error question.
Since I’m using AMD cards which version of the driver would you recommend? Currently I am using the August 23th 2017 Beta Blockchain version of the driver (17.30.1029). Let me know what your opinion.
@wrapper Thank I’m very happy to be part of the team.

For the pre-RX cards, use 14.6 beta (Linux) or 14.7 RC3 (Windows). It doesn’t matter much what drivers to use with the RX cards. Although earlier 16.x are a little bit faster than the recently released ones.

I hope I’m not being any trouble. Just really trying to be more knowledgeable in mining. For you taking time to answer I completely appreciate the replies.
I don’t know if you know much of the mining pools out their. I use give-me-coins, I’m slightly not knowledge about the consistency of hash rates between pools and the miner program. My total has rate right now is about 950KH/s to 1.1MH/s on the pool it does not reflect it correctly as it will jump from 600KH/s to 1.1KH/s.
Correct me if I’m wrong, but the miner shows it steady hasrate and send the information to the pool can have incorrect data or delays? Or is Neoscrypt algorithm takes the amount of hash rate need to solve a block? For example if the block found is large it will ask for more hash versus a smaller block?
-
Pools calculate your hash rate based on difficulty of shares submitted in a certain, not very long usually, time frame. It’s variable because mining luck is random. The miner shows the actual hashing performance over the last 5 seconds, the average performance since start-up and another average based on difficulty of shares submitted.

Sorry to continue My post. As of now I’m still trying to optimize my RX Sapphire 570/470 nitroplus 8gb. I only get about 430kh/s as you mention before @ghostlander your RX 580/480 is getting about 500 to 550 if I’m not mistaken. With the RX 570/470 it should be around 480 to 490 as it just a one step down module. I’ve tried modding the bios with what I found on the internet, but there was not much out there for my GPU. The ones I did find Windows 10 64bit never recognized the card. I’m at a stand still as I can not grab more HD Sapphire 7970. Any other suggestions?
Also in you recommendation (Others are welcome also) I completely like you NSGminer. What does better miner Feathercoin AMD or Nvidia?
-
Also with your NSGminer, when I remove the .Bin file for it to generate new ones with new settings. The miner crashes or it does not mine as it can not create the .bin files.
So I’m using an old .bin files from version 0.9.2. Is there something wrong? Or am I doing anything wrong?
-
@grimreaperminer It shouldn’t crash unless there is something wrong with the drivers, SDK, etc. What’s in the log?

@ghostlander This may be a newbie question (sorry), but I have to ask it. I am using R9 280x and 7850s. it sounds like I should be using the 14.7 RC3 (Windows) drivers for best results. How do I get this older driver? I checked AMD’s site - I see the 14.4 and 14.9 but not the 14.7 drivers. I am running on a Win 10 machine.
Thanks in advance, and appreciate your forbearance of a bit of newbie.

1 - Go to google.com
2 - search for “AMD 14.7 Drivers”
3 - the first link is from Guru3D and has a download link to the drivers.http://www.guru3d.com/files-details/amd-catalyst-14-7-rc3-(14-200-1004-august-11)-download.html
I hope this helps
