nvidia/linux upgraded from 390 to 410 drivers, hashrate drops after overclocking

[cryptoyes]

I'm hoping someone hit this and can advise. Like title says:
- ubuntu 16.04, with a few 1070 and 1080ti
- had nvidia 390.48, cuda 9.1, all running fine for months (mainly ethminer 0.14)
- upgraded to nvidia 410.66
- without overclocking i get the expected performance
- as soon as i overclock either memory or gpu clock even by 1 mhz, hashrate drops to less than 10% of stock!
- installed cuda 10 ... made no difference (as expected)

Anyone?

Hours ago I installed the latest driver from 394 to 416 driver for 1080ti but it seems the hashrate drop that is why I downgraded it to 399.24 driver version.
Try to downgrade it below 400 version of Nvidia card. It may fix your issue.

Or maybe you are using an old mining software so try to update it too to the newer version to make it work.

Probably mining software programs like Nicehash , Claymore Miners, EBWF miner etc needs to be updated in order to take full advantage of the new GDDR6 memory technology in these newer cards. I think we will have to wait just a little bit more until these miners are updated. In the mean time you can continue with the 39x.xx version of Nvidia drivers.

All software run just fine on 396.48 (I'm not new to this). Also tried newer versions of ethminer (in fact I tried all from 0.12 to 0.16.1).

Has anyone here *ACTUALLY* used 410.66 under Ubuntu 16.04 with nvidia 1070/1080/1070ti/1080ti ?

Note that these drivers were released *today*.

@swogerino gddr6 has nothing to do with it (gtx10x0 doesn't use gddr6).

You should ask around in the z-enemy and t-rex discords. These 2 miners are cuda10 compatible. Somes might have experienced your problem.

Yes you are right about Gtx 10 series and I made an error by not explaining well, I mean that the new Rtx 20 series will be able to squeeze more out of them with the new mining software programs, as these new versions need to extract the full power of Gddr6. This is what I mean.

I've seen reports of people using 410.66 and not reporting such issues. It may be linked to the motherboard I'm using (Asrock BTC+ with 13 pcie slots).

410.66 are useless to me for now. I can also confirm that CUDA is not at fault (the problem is there regardless which version of CUDA I'm using, be it 8, 9.1, 9.2 or 10)

Totally standard Linux stuff for headless:

Code:

nvidia-xconfig --silent --cool-bits=28 --custom-edid=HDMI-0:/node/1280x720.bin \
        --connected-monitor=HDMI-0 --no-connect-to-acpid --enable-all-gpus \
        --allow-empty-initial-configuration --output-xconfig="x.conf"
xinit -- Xorg :1 -config "x.conf" -logfile "$base.log" -quiet &
DISPLAY=:1 nvidia-settings -a "[gpu:0]/GPUGraphicsClockOffset[3]=10

Performance is stock until I execute the above. Then it drops to about 10% of stock, regardless of what I overclock or by how much (even 0).

Something's fishy ...
