Title: Did my second R290 Burned ? Post by: DimaDolgov on July 23, 2017, 08:54:19 AM Hey guys..
i just noticed that one out of two r290 have only 4 Mh/s and the second 28Mh/s ETH: GPU0 4.206 Mh/s, GPU1 28.024 Mh/s ETH: 07/23/17-11:51:44 - SHARE FOUND - (GPU 1) ETH: Share accepted (109 ms)!

Post by: Undefined31415 on July 23, 2017, 09:38:44 AM Try using it as a graphics card is typically used & check for video output. Title: Re: Did my second R290 Burned ? Post by: vectisitch on July 23, 2017, 11:41:13 AM these are fantastic mining cards but they do get very hot as you probably know and the pcie plugs burn. check the plugs on the psu and card. it's all about the cooling on these. as much airflow as you can get round your rigs will help a lot
Title: Re: Did my second R290 Burned ? Post by: DimaDolgov on July 23, 2017, 11:44:53 AM my rig is located in server room ( 47c all gpus )
Title: Re: Did my second R290 Burned ? Post by: vectisitch on July 23, 2017, 11:50:53 AM thats good then. check the plugs on both the gpus and psus though. they do burn even if cooling is good sometimes. other than that, try all your cards one at a time in the pcie slot without the risers if your are using them to see if the card is still giving low hash. could be a dodgy riser also

restart the computer should bring it back to speed, but will be slowed again if overheating is a problem Title: Re: Did my second R290 Burned ?

"my rig is located in server room ( 47c all gpus )" so overheat is not a problem Title: Re: Did my second R290 Burned ?

"my rig is located in server room ( 47c all gpus )" so overheat is not a problem Might need a dummy plug in the HDMI port to trick the card into thinking there is a monitor plugged in Title: Re: Did my second R290 Burned ? Post by: QuintLeo on July 24, 2017, 10:25:39 PM If you can't see the temps on both cards, you probably had a glitch and a driver reset that has confused things.
Reboot is the cure. Title: Re: Did my second R290 Burned ? Post by: philipma1957 on July 25, 2017, 12:03:42 AM classic 4mh driver bug
plug a monitor into it and restart the pc it should work. 7mh is overheated and software downclock to cool gear off. Title: Re: Did my second R290 Burned ? Post by: YIz on July 25, 2017, 12:49:50 AM I had this issue with a card too, it actually fixed itself after I reinstalled the driver.
Title: Re: Did my second R290 Burned ? Post by: Yurickz on July 25, 2017, 01:09:34 AM I had a similiar problem with one of my R9 390's, it had shitty hashrates until I plugged in a monitor.
Title: Re: Did my second R290 Burned ? Post by: DimaDolgov on July 25, 2017, 06:49:47 AM i reinstalled AMD drivers and MSI-AB
nothing helped >:( Title: Re: Did my second R290 Burned ? Post by: QuintLeo on July 25, 2017, 08:04:12 AM Then put a dongle or a HDMI-VGA adapter on the problem card.
