Topic: GTX 970 All the sudden drops to 3 MHs after running a month (Read 1407 times)
I got it the card to work without the riser directlly into motherboard... Doesnt matter if I tried different of the same riser still would get 3MHs. It worked before with a riser, what changed?

do an ASIC quality test (google search).
check nvidiainspector to see the p-state and current clocks its using when you see the low hashrate.
Theres also an app that allows you to see how many failed calculations/errors it has while mining, but I am unfamiliar, and have only see a screenshot of its results once, so I can't help much there. It was able to show a guy's card that would put out 21Mh, but 30% of those or more were pure errors..... which explained his poolside hashrate of <10Mh.

We're your cards over/underclocked?
It used to be. I am mining zcash with its getting normal sol's 302 for the one card....

Try using genoils miner if you're going for ether. I'm currently running at 22Mh/s per GTX 970 on the latest Nvidia drivers. (I also enabled Optimize for Compute Performance in the Nvidia control panel)
Tried, but it quits ...

As the Ethereum epochs increase, some GPUs (the 970 is a particular example) are going to be drammaticaly losing hashrate over the coming months.

I watched the video, but the comments said that guys stil getting 18mhs... I tired in Ubuntu and I got dag file is too big.

I cant find the compute performace. I select ethminer64.exe and I dont have anything about compute.
Ill try the driver, and I did the DD.
Try the 347.52 nvidia driver http://www.nvidia.com/download/driverResults.aspx/81877/en-us
Try uninstalling the drivers and check for thermal throttling.
Most likely a driver issue, nvidia driver crashing/corrupt. Ive run into similar issues, the only fix that truly works for me and is consistent is to use DD uninstaller to remove all traces of the driver, reboot, then reinstall the driver, reboot, then test. I havnt had this NOT work as of yet. Simply reinstalling or uninstalling doesnt seem to work for me.

Done that, even windows.
I set it to default no go
Check your temps are ok. One of my fans seized up on mine and put the tempatures way up high enough to throttle the card right back. If youve got it overclocked then try putting it back to standard reset computer etrc and try again.
Anyone have any suggestions?
I have been mining in Claymores 9.3 with ether with the driver 350.12 it was going fine 22MHs, last night i reboot and i get 3 MHs... i have automatic drivers install disabled, windows update disabled so none of that happened. I reinstalled the 350.12 driver.. nothing I tried to update the driver 372.54.. nothing .. update windows 10 creators.. nothing. I don't know what to do. And i replaced the riser.
