RX Vega 64 invalid shares on CN Heavy (bittube, haven, etc)

[xmronadaily]

Please provide as much as possible information to reproduce the issue.

Basic information

RX Vega 64 giving invalid shares on all drivers 18.3.4, 18.5.1, 18.5.2, 18.6.1 when mining CN Heavy algos. (Haven, bittube)

This seems to be only specific to Vega cards as I have r9 290x cards running on CN heavy and all shares are valid for them.

Other than that, all other algos are fine for both vega and r9 290x cards (CN2, cn-fast, etc.... )

One note however: I had this working properly somehow before, up until yesterday when I reinstalled windows. So, the openclcache was somehow compiled good previously in all the drivers that I used, and I had no problems with Vegas on CN heavy, but now after Windows reinstall and HDD format, it just doesn't work...

Compile issues

• Which OS do you use? Win 10 64

Used ready binaries and compiled myself, no difference.

I'm mining BitTube using XMRSTAK 2.7.1, with AMD Driver 18.5.1, Vega 64 Card, no issues.

I'm using dual intensity of 976. May be able to go higher, but this works. If your using higher intensity, try this for a starting point.

[xmronadaily]

Hmmm, that is really strange, but really good to know! I've even used lower intensity of dual 960, but it would give invalid shares no matter what... Could you please tell me what other parameters you have in your amd config? And also are your cards running at 1100 memory or stock?

[BKdilse]

  { "index" : 1, "intensity" : 976, "worksize" : 16, "affine_to_cpu" : false, "strided_index" : 2, "mem_chunk" : 2, "unroll" : 2, "comp_mode" : false },
  { "index" : 1, "intensity" : 976, "worksize" : 16, "affine_to_cpu" : false, "strided_index" : 2, "mem_chunk" : 2, "unroll" : 2, "comp_mode" : false },

Card: Mem_P3=1100;905 / GPU_P7=1408;905

[xmronadaily]

Okay, thank you so much! I'm in 18.6.1 atm, I'll try reverting to 18.5.1 and with your settings, I'll update how it goes! Also I'm running same core and memory clock as you, so no deviation there :)

[BKdilse]

No probs, I've had problems with 18.6.1, so have stuck with 18.5.1. Of course, update here, and close if fixed for you, so it saves the devs time with all issues :)

Also if you fancy trying a smaller pool, please check out https://tube.pool.gntl.co.uk

[xmronadaily]

@BKdilse So I just tried it, with your amd config setting and 18.5.1 driver, but no luck, invalid shares again... But the thing is, it was working fine until I did a windows reinstall a couple of days ago, so it has to be something with files in .openclcache not getting compiled properly.

Is there any way that you could please go to your C:\Users\youruserhere\AppData\Local.openclcache and and send me over the openclbin files you have there? I'd copy-paste in my folder and try that as last resort, other than that, don't know what to do... Thank you so much for your input here!

[unsivilaudio]

You have been clearing your opencl cache files between driver changes?

[xmronadaily]

@unsivilaudio Yeah, every time. Tried on every possible version with clear cache, and miner would recompile the bins, but it never fixed the invalid shares...

[unsivilaudio]

I'll give it a shot, I'm on 18.6.1 currently.

Yeah working fine for me, I even deleted my cache and let it rebuild.

2 threads, 896 intensity, worksize 16, strided_index 2, mem_chunk 16

[BKdilse]

Yes, I always clear my cache with driver/xmr-stak updates.

[xmronadaily]

No idea what's wrong then, what windows version are you on?

[xmronadaily]

Can you please share your openclcache files with me? I'd really appreciate it if it's a way to get it working :)

[xmronadaily]

Some great news at last! @BKdilse You sir, saved my life! So, Vegas are finally submitting valid shares on CN heavy!!! 100% acceptance. But what I had to do was the following, I took your openclbin and pasted it in my folder, but when I ran the miner, it still started compiling its own file, and then it submitted invalid shares again...

But then I went back to the openclcache folder and renamed your file to fit the name of the file the miner just compiled:

I renamed "eb80a01cc8fe1c292765149194af6ee11bf5c990404dcd17c7fbf80241db3867" to "766d71af38aa097ade9860cf4638d2a5b2106eab8db3f958e6690bae6c23bdd7"

And now when I ran it, it was actually selecting your file and works just fine!

I'm just happy it got fixed and thank you so much for your help and contribution and sending me that crucial bin! I'm backing up that and saving it like gold! :D

[BKdilse]

That's a really weird issue, but glad you have it sorted. No problems.

[unsivilaudio]

Yeah this says to me you aren't fully uninstalling the bad drivers. You should use DDU in safe mode.

[xmronadaily]

Oh but I was, every time I ran ddu in safe mode, unless it was somehow fucking up and windows was maybe at fault... I had this issue before actually https://github.com/fireice-uk/xmr-stak/issues/2124

There I did the same thing, I ddu in safe mode and installed 18.6.1 actually and then it worked fine, I was doing the same thing now, but on different windows, and it wasn't working, luckily those bins BKdilse sent worked... Don't know what caused it, the only variable left is Windows versions, the other one was some older cracked version from TPB (dont know what edition) and the current one is Home dled from Microsoft's site. Really weird this whole thing...

[xmronadaily]

@BKdilse Did you try running your cards for CN heavy at worksize of 8? It should give a small hashrate bump, as well as memchunk, I think going 10 for memchunk up from 2 also increases hashrate. It does for me, but I can't use those settings since it's instant invalid shares 'cause the only working bins are yours :D

[BKdilse]

@xmronadaily I've played with various settings in the past, and settled with the ones I have. I'll give it another go though :)

[xmronadaily]

Yeap! Do check it out and see if there's an improvement for you :)

[xmronadaily]

Resolved the issue:

Reinstalled windows again, installed 18.5.1 drivers and made sure to only run vega cards in amd.txt config when they're compiling the binaries, running them in conjuction with other cards produces faulty binaries for vegas. After good binaries are compiled, you can add other cards to amd config file and vegas still run fine.

I tested this on 18.3.4 as well.
