AMD GPU Mining Not Working

[dtawom]

I'm getting 0 Sols/sec with AMD GPU mining for on a R7 260x on Win 10 x64. I'm running with just the GPU switch and it is detecting the card properly at the beginning. Mining with the cpu switch works fine, and the gpu switch works fine on my other Nvidia system. The switches I'm using are: nheqminer.exe -l stratum.zcash.nicehash.com:3357 -u mypublicaddress -t 0 -od 0 Note: Per a suggestion on another thread I have tried both the 15.12 drivers and the 15.11 drivers with the same results. I don't think the drivers are the only problem. Anything other suggestions for me to try would be much appreciated, like OS version, or other applications that might be interfering with it. The below picture is the results I was getting with the 15.12 drivers, but I got the same results with the newest drivers from AMD as well as the 15.11 drivers.

Looks like you don't have enough VRAM. Long story short is some cards can't single allocate 800mb. This issue is solved with v4 silent army. I forked the code and updating to v4. I already have working builds so just be patient for the moment

Try Genoil's ZEC silentarmy miner with -i 16 or 18. It should work: -i parameter sets 2-log of equihash bucket size & OpenCL global work size. Only the following values are supported: 20, 19, 18, 16. Lower values will usually lower performance, but free up GPU resources for desktop work or dual mining.

I forked, and made a build that has silent army v4:

Thanks maztheman, it's working great. Hate to be a bother but I'm trying to start this up on another system that has an Nvidia GTX 580 w 1.5GB of VRAM and I'm having the same issue. I've tried with both the 0.4c and the 0.4b with the same results.

[maztheman]

With the gtx 580 since it's only open CL 1.1. That could be a reason why it won't compile. I'm working on a cuda version. Stay tuned.

@maztheman have you got a v5 fork?

[maztheman]

I'm working on it. It's almost ready just working out some some bugs. I know a lot of people are waiting but I'm out of town and so it'll have to wait. Thanks for your patience.

@maztheman the latest 0.4g release is crashing on workstations with Radeon cards. The two that I've seen this behavior on have a r7 260 and an integrated r7 apu. Saw somebody boasting about 100 sol/s on a R9 nano card with somebody else's release so I've got a couple fury's on the way. Hopefully Silentarmy will do just as well. I really like your build and appreciate your help. I thought adding color coding to the lines was a nice touch in the last release.

[maztheman]

It's crashing probably because of old bin files. Please delete them and it'll probably work. I'm updating to v5 pretty soon here. Sorry for the problem

[dtawom]

@maztheman I noticed you "#Added Gtx 500 series compatibility with v0.4g_sm20" so I tried it out today, but I'm still getting 0 sol/s with GTX 580 1.5GB BTW clearing the bin files did stop the crashing so I'm making sure to clear the directory before extracting the newest releases.

Thanks in Advance,

Hello. So Radeon r7 260x working without problem now? What is hashrate on the newest software?

AMD (OpenCL) solver are dropped from nheqminer. Closing issue...
