Thanks but I have already tried the devcon tool and it did the same thing.
It claimed to have enabled it but the device manager still shows it as disabled with a yellow exclamation icon.

Only the non-blockchain drivers allow me to disable and re-enable the card.

If you follow the instructions he gave you with devcon.exe and a batfile it might work.

Thanks. I have already applied the Aug23 blockchain drivers after running DDU. I have tried to disable the card in device manager but it would not allow me to re-enable the card again. I get a code 43 error.

For those of you that have Vega hashing at a high rate can I ask what Motherboard and CPU combo you are running?

I have tried two different motherboards (TB250-BTC, Asus Z270-P) and have not managed to get more than 1350 H/s.
Both motherboards I have tried were running Kabylake CPUs (G3950, G4560).

Thinking of trying out a Skylake processor in case there is an issue with Kabylake and Vega.

Thanks

Highly doubt your mobo/CPU combo has any effect. I have one system using an ASRock H110 and G4600, and another setup with an older P8Z77 motherboard and Core i5 (on DDR3!). All my cards are running roughly 1950-70 H/s avg.

1350 sounds like your cards aren't being properly served by the driver. Make sure you have the August Blockchain driver and that you've reset your cards prior to starting your miner.

I'm actually using the IGPU for display instead of the Vega. I have tried an X370 AM4 board as well as an older Z77 with similar results. The X370 had a Ryzen 1700 on it so no onboard GPU.

I have a feeling it could be a BIOS issue on the TB250. May also look at picking up an Asus Z270-P. The TB250 has been flawless with 7 x Nvidia cards.

Anyone experience issues with manually resetting their Vega cards in device manager?

I cannot re-enable my Vega 56 in device manager after disabling. Toggling HBCC in Wattman causes the driver to crash and the card is missing from Wattman. The only way to fix this is to reboot the rig.

Using the latest Aug23 block chain drivers in Windows 10 x64 with latest creators update 1709 (have tried previous Windows 10 builds with similar results)

The only driver that allows me to reset the cards is the latest 17.11.1 driver but from what I can tell this is not the optimal driver for mining.

Only getting a max hash rate of 1300H/s using cast-xmr from a single Vega 56 when others are getting much higher.

Spent 2 days so far with no luck.

My system specs
Motherboard: Biostar TB250-BTC
Memory: 1x8GB
CPU: Celeron G3950
Video cards: Just a single Vega 56 + integrated GPU
Virtual memory: Fixed at 64GB

Any help appreciated.

I have this problem occasionally now I have swapped to the same MB as you never had any issues with the z270 switching on the HBCC. I found that the problem is switching on the HBCC on a card that your using for display, so whatever card has hdmi in causes BSOD/freezing. Have you tried resetting cards whole.using onboard graphics?
