Hi thanks for answer

I checked with HWinfo and i have no errors.

What are eres and lidag options for?

I got some screenshots here showing the randomness of this weird problem.
In the first Screenshot i am on stock bios and Only 2 gpus generate dag and hash, while on the next 2 screenshots i am on modded bios for mining, here all 6 gpus generate dag and hash.
Thing is it is random, it can happen in reverse aswell, or other times only 3 gpus don't hash or only 1.It has no specfic rule.It is random.

Here it is the first screenshot on stock bios with 4 gpus not generating DAG and hashing with 0.All 6 GPUS are starting up but only 2 generate DAG, so 4 GPUS will hash with 0.

Second pair of screenshots.This is after restart and switching to moded bios.All 6 Gpus start up and all generate dag successfully.
