@NovaMiner I had the same problem. The easiest way for me was to run my evga card on Windows to flash the updated evga vbios to the card. You have to download the latest version of evga Precision. Then unhook/disconnect all cards except the evga you want to flash the vbios on. Disable CSM and fastboot in your mobo bios and then hit the rebar tab in evga Precision software, then update vbios. Works like a charm now. Hope this helps.
It is a known issue with non ftw3 3080 ti cards. Evga released the updated vbios to address it…
i have similar issue but not as bad i hit around 77-79 mh (after stable)
Hit 82mh first time hash.
I have 1 palit gaming pro
1 evga xc3 (updated Precision x1)
have not change thermal pad, but according to it doesnt seemed like thermal pad issue?
hi , 2card with same config with same brand but 1card is normal another is OC .
palit in normal mod is better than OC card !!!
Hey msjavod77, did you flash the bios of those 3080TI to Palit, or are they original Palit cards? My MSI card just won’t work well, I’m wondering if I could flash a Palit bio on it?

Found the updated Bios 94.02.71.80.BF for the 12G-P5-3953-KR card on Techpowerup and wondering if I can just flash it to my GPU via HiveOS?
Dear fanjo ,
It’s Orginal bios ,
Hey Guys,
I’m having the same issue, i thought it was because of my old motherboard ( from 2014), but I changed it today for my PC Motherboard, and nothing…
The oc’s isn’t too aggressive, but is very low.
What’s interesting is that you have Gigabyte cards at 61/62 MH… similar to my MSI at 59
Maybe some better LHR with newer cards??!
Did you try upgrade the Gpu Driver? I’ll probably upgrade mine rn to check
I saw in another post, ppl getting 90mhs on 3080 ti LHR 
hi,
Can you try
lock clock: 1650
memory clock: 1700
miner command
“lhr-mode”: “1” (default value)
can you try memory oc “0”
lock clock: 1650
memory : 0
I spend 8 hours to play with that- Gigabyte 3080ti LHR NBminer. I updated nvidia drivers, hiveOS everything. Tried all type of OC, nothing worked. In the end of the day i just set 73.5 LHR unlock static with mode 1 and the gpu flied away to 88-89 stable MH/S.
My OC on the card is core: 0 , mem :2600, PL: 290, but that is not the optimal values still have to work on that OC.
You are welcome 
Tried this OC to test, but still fluctuating the hashs…
I got this erro rn, when I was testing.
GPU 0 is the 3080TI
2600 is too high for some cards. better to test step by step for best value
i have 2 suprim x but, i have 2 diffrent overclock settings,
if GPU4 1800+ memory overclock, decreasing mh.
if GPU5 2400+ memory overclock computer freeze, some times can restart some times freeze wait.
Not all settings apply to all cards.
i understand, but i would still try without CoreClock but ye silicon lottery is a shitty thing 
i’m just suggeting.
yes true silicon lottery
