DAG verification detected xxx defect segment(s)

Miners

Hi

I got the awesome idea of upgrading from 0.6-217 to 0.6-219 as it is highly recommended in all threads and from this point my rig is wreck …

I got such message from lolminer
I tried to downgrade 0.6-219 to 0.6-217 same behaviour
I tried to set only one GPU installed, same also
Everything is fine if mining FLUX

Any idea ?

Toggled –disable-dag-verify to disable DAG verification. This turned back normal situation, no invalid share

This situation doesn’t explain what suddenly happend on 11 GPUs (R9 380/R9 380X)
All the same setting working fine since 1 year like this …

I don’t believe Hawaii architecture cards are supported on the latest kernel/driver

It looks like it does. I am now running OS 0.6-219 with AMD drivers 21.40.1 with DAG check disabled.
169 shares accepted, 0 rejected
lolminer sounds to be last one supporting Hawai / Tahiti
For Tahiti I have to use AMD drivers 20.40 with OS 0.6-212

I suspect motherboard / RAM / CPU.
I allready got a G4400 fried on this rig, the CPU was very often around 3% load.
I changed the motherboard and CPU, now I am @ 1.5% CPU load.

I saw on reddit people solving such problem reinstalling full fresh image.
Will try it next days.

I got something similar on lolminer (on a current card), but worked fine on trm. Have you tried a different miner?

6

I did but not with ETH/ETC. lolminer seems to be the last one to run correctly with Tahiti GPU

I tried to mine FLUX, it was ok
