Topic: AMD Releases Driver for DAG Issue !!! (Read 28827 times)

The blockchain driver fixes the Dag file epoch hash drop issue that Polaris cards have with Ethash coins that have a Dag file larger than 2GB. No difference in other algorithms.

Thanks Vann!

Will the blockchain driver increase hashrates across the board or is it just when mining ETH?

The blockchain driver released by AMD has issues on Windows 7. You can try installing the blockchain driver released by Robinhood manually after running DDU in safe mode to uninstall all the GPU drivers. Make sure to enable the option in DDU to disable the Windows automatic driver install. Then just reboot and install the driver manually. With a modded Bios on a RX 570 you also need to run the pixel patch to disable the driver signature check after installing the driver or you will have a code 43 error in the Windows Device Manager and the cards won't work.

sorry to be that hobbyist dude who jumps on a forum, reads the first ten posts of a 14 page thread, and then asks noobish questions... but here goes.

I followed the directions in this video that i found (haha fake news russia ha ha)
https://ruclip.com/video/EXLahUxmTOI/how-to-optimize-amd-rx-470480570580-cards-for-mining-full-guide.html

i used the right rom to flash the bios on my card (RX 570 Elpida 1750MHz). i made sure to get the most recent win7 64 bit version of all of the tools and utilities involved. nothing fails during install (i have not scoured log files as i don't know what is normal or what to look for). when i'm done, gpu-z looks happy, windows is happy, but none of my miners will run. all of the benchmark test on nicehash fail. i was on a smartcash pool and that won't work either.

i revert to original card bios and wipe the drivers again and put the factory DVD driver install disk back in... and I'm back up and running. weird thing though, when the factory drivers / bios are installed and everything works, GPU-z says the Bandwidth is Unknown, GPU Clock Memory reads 0 MHz, everything else appears normal.

so it appears to just be that the AMD blockchain driver doesn't work on my machine and/or i need more or fewer windows updates. it's an older machine (2011 intel board that i had to flash the bios on to get it to recognize the PCIe 3.0 card), so maybe i just need an actual properly built modern computer...

anyone have any ideas, instructions, links that i can't find with my own googling skills, snarky and cutting but true replies about my stupid noobish post?

thanks folks!

And why on Windows 7 there is no "Compute" option in Wattman settings?

Is there a dag fix for windows 8.1? All these drivers are for 10 and 7...no support for 8.1? Why?

RX 480 + RX 580 + RX 570 here.

Newest AMD drivers do have equal performance to August blockchain drivers, but they aren't stable on my rig. Claymore's crashes often, even Firefox crashes, for god's sake.

Reverting to August drivers fixed it. Never had an issue with them.

try to install driver from device manager, and located the file amd driver for dag issue... and then patch atikmdag maybe it can solved the problem...

Install Blockchain drivers and there will be no problem. The only "catch" is, that they only work on win10

With the newest driver 17.11.2 the problem is still there, is there any workaround?

new drivers have mode to switch between graphics and compute
test with them

SGMINER mines fine I just discovered. Switching back to Claymore now to see if it crashes again.

bad card or riser

SO my drivers have recently started crashing as of yesterday, cannot get my machine stable. Using the August block chain drivers.

atikmdag.sys and dxgkrnl.sys crash. Reports that THREAD_STUCK_IN_DEVICE_DRIVER

Yes, it does.
Download drivers -> Uninstall previous version drivers via DDU in Safe mode -> Install Blockchain Drivers normally using GUI -> Patch drivers using AMD Pixel clock patcher -> Restart.

does this also work with bios modded cards?

Yes, try Claymore v10.0 miner. Use -mvddc to set memory voltage and -cvddc to set core voltage.

Hi guys,

any news about an easy  way  to  geht the higher mhs with volt control?

Claymore released new miner. It's not ideal, but it should help.

Am I the only one mining still without the fix? I couldnt get it to work and had some success undervolting my cards thru the bios. I wish their was a more simple guide how to tune these rx 4xx cards thru batch. AB didn't work for me and watt tool obviously shows me 0s. So I'm running at 25mhs currently on my 2 rigs without the fix
