So, I finally fixed the issue. Originally my GPU's were attached to a gigabyte AMD motherboard. When I upgraded the motherboard to the ASRock H81, I just moved the GPU's and SSD from the AMD mb to the ASRock mb, and they worked straight away. When I re-installed Windows, the GPU's wouldn't mine anymore. I figured it must have been something residual from the AMD motherboard drivers that allowed the GPU's to work after the hardware swap. As I couldn't reinstall the AMD motherboard drivers while the hard disk was still attached to the ASRock motherboard (I tried), I swappped the motherboard back to the AMD, re-installed the AMD motherboard drivers, swapped the motherboards again, and now the GPU's work.

Maybe something to do with Open CL 2.0?

There's probably a much easier way, but it works again.

Thanks again

Thanks for the reply. Using Windows 8.1 Pro, which is definitely installed. All updated after each re-install too. I't driving me mad, I can't see any difference from before the re-install. Miner config files are the same as before, indexes correct and cpu mining disabled in the config.

Hi

Sorry to jump on this thread, but I'm pulling my hair out here.

I was running Wolf's XMR Miner without a problem on an ASRock H81 Pro, mining on a few RX460's. I was having problems with my Windows 8.1 License, so re-installed windows.

Since re-installing Windows, when I try to run Wolf's XMR Miner, I get "Error -1 when calling clGetDeviceIDs for number of devices".
I have tried several versions of the Radeon driver and re-installed windows from scratch again, with the same result.
I've tried with just 1 gpu, and swapped that a few times, and tried different risers and slots, in case it's a problem with one of the cards or risers.
I have disabled on board graphics.

The GPU's are recognised in MSI Afterburner with full control over all sliders. TechPowerUp GPU-Z also recognises each card.

I just can't figure out why Wolf won't work.

Any ideas?

Many thanks

Mr S

Hi

I have a problem here. I have been mining monero all night and can see my graph shows a steady-ish hash of 650 all night, yet my estimate is stuck and hovering at about 0.00029, My valid shares are increasing slowly, I have zero unconfirmed balance and my confirmed hasn't budged in hours. Is there a problem?

Thanks

Edit: After a couple more hours and no change, I've moved to a different pool for the time being. If there's a temporary problem, and my confirmed balance updates, I'll come back.
