Thanks, buddy for all your help. Tried everything and nothing seems to be working for me.
Looks like, I am in a soup.

I am trying to figure it out on my own and see if I can find something.
If you happen to stumble upon any new information, please do share it with me.

Thanks!

Just built a new machine on a different set of motherboard, CPU, RAM, and clean installed Windows 10 on it.
Then removed GPU card from the old motherboard and installed it on the newly built system and then installed 470.05 from your link. Also, connected the HDMI monitor.
But, the result is still the same. I am getting only 23 to 24 MH/s when running Nicehash Quick Miner.

Any other ideas/suggestions would be greatly appreciated.
Thanks.

Hmm ok.
I will do that. I will set up Windows 10 on a different SSD (I already have one) and try setting it up again.
Will get back to you with my findings.

Here it is
GIGABYTE Nvidia GeForce RTX™ 3060 Gaming OC 12GB GDDR6 Graphics Card (GV-N3060GAMING OC-12GD)

Thanks for responding.
GPU is directly installed on the motherboard (ASRock A320M-HDV R4.0 Motherboard (BIOS Updated for Ryzen 3rd Gen Processors) with 4 SATA3, 1 Ultra M.2 (PCIe Gen3 x4 & SATA3)).
I installed the driver from somewhere on the web before I found your post. But it is indeed 470.05. After installing the driver, when I open NVIDIA Control Panel, I can see the driver version as 470.05.

Hello Guys,
I am a newbie and after doing whatever research I could, found a non-LHR version of RTX 3060 on Amazon. Paid about $1100 for it.
I set it up on a PCI e x16 slot on my motherboard and installed 470.05 drivers.
Started mining using Quick miner on nicehash and used all the default settings.
I have an HDMI monitor connected to it all the time.

Now, after several days of tweaking and playing around with it, I could only manage 24 mh/s. I want to be able to mine at 50 mh/s.
Can someone please help me and guide me on what I might be doing wrong?

Thanks in advance!
Nitin
