I do not have a pc at the moment to check with GPU-Z. Let me know if these helped:)
Thanks friend, i have flashed 0C it hides memory maker but gpu-z shows, if you do with negative clock on memory it hynix 99%. I think 0C is for samsung memory i will check dump differences.
Hi Dear,
i also have 2060 with hynix memory, bios: 90.04.63.80.0F and with stock settings i get 19-20 mh and with some oc i get 22.00-24.11 mh.
If the problem is in the BIOS can you share how to update/downgrade it?
What is your OC’s?
Stock setting - 19-20 mh
PL 72, CC curve, MC +850 , 22 mh
PL72, CC curve, MC -502, 24.1 mh
Flash bios from upper post “RTX 2060 D6 6G Rev 2.0 Only says GDDR6 memory “. It is for samsung i flashed same on Hynix, his dump is identical as from reddit i have flashed. Upload your GPU-Z picture after flashing, and dump to compare with my. I want to be sure it is 100% identical( there could be 2 versions only for new revision of that card)
Do dump your vbios first and save it, nvtool in windows, after dump you flash.
Tutorial is easy you have on thechpower site, on google…
It is important to know that you flash at your responsibility!
Use negative memory clock -1004 and core 930 or 1050, try.
I’ll check today what i have and what i need.
I should flash it in order to be happy with the hashrate 
This looks like mine before flash, this is to compare to know its same:
After flash please, restart and take screen shot and share
Hi Dear,
i changed the BIOS today. The hashrate jumped from 24 to 29.21mh. Curve 1050, MC -502 (Windows)
Now i’ll check how stable it stay.
If i use MC + the hashrate stay at 22.11
I’m adding a photo of the new BIOS just to check with yours:
Another thing:
yesterday i checked a russian forum, the guys have the same problem.
They use the OC rom to jump to the 29mh
but they also use another rom to jump to to 32mh
I have them both , but still didn’t try.
I’ll post some screenshots of the conversation there - i used google translate so the english is not very good and sorry for that.
I dont know if it’s allowed to post here the direct link to the other forum, if yes i’ll do it.
Thats why i use same ID bios and flashed with 0C and told you it will work
We see what will came out but def. it is LHR .
I tested : GeForceRTX2060-6G-90.04.63.40.AF.rom
from VGA Bios Collection: Gigabyte RTX 2060 6 GB | TechPowerUp
thank you @ stefcho11
You’re welcome.
What was your original bios version? ‘‘90.04.63.80.0F’’ ?
yes, original “90.04.63.80.0F” Model name: GeForce RTX2060 D6 6G (GV-N2060D6-6GD) NVIDIA RTX 2060/REV 2.0 GIGABYTE
You had the original one and flashed direct to the …40.AF
or first you had the original, then you flashed to …80.OC and then the 40.AF?
Just asking to make my strategy what to put first and what next
first I flashed …80.0C and then …40.AF, because first I don’t know about …40.AF
Nice.
Please write back in a few days to say if it runs stable or if you have any problems.
Thanks
So we can confirm that bios " 90.04.63.80.0F" is an LHR version.
Glad you push it through 
absolute ! thank you, again !
