Issues with new 3080 installation

[foggl3]

Hello all,

 

I am having some issues installing a new Asus TUF 3080, purchased initially on Saturday May 03, from a Gigabyte 1080ti. My current system is as follows:

 

Ryzen 5 3600 with a bequiet! Dark Rock Slim cooler

Gigabyte X570 Aorus Elite Wifi 

G Skill Trident Z 2x8GB 3600Mhz

EVGA Supernova 750G2 with 2 individual 6+2 pin VGA cables (approx 3 years old)

500GB Samsung 970 nvme drive (primary drive)

250GB Crucial SATA SSD

2TB HDD

4TB HDD

5ea case fans in a Corsair C70 Vengence

 

My issue(s) is that with the new GPU installed, my system will be slow to boot, Windows is slow to respond if able to log in at all, freezes while logging in to Windows, and after a restart will not POST. If I swap back to the 1080ti, I have none of these problems. 

 

Here is what I have tried, in order, to remedy the situation:

 

With the 1080ti installed, ran DDU in safe mode to remove existing drivers with the latest 3080 driver from Nvidia downloaded. No change.

Downloaded and installed current BIOS update from Gigabyte (this went from a no POST status to able to log in to Windows but extremely slow to respond to input)

Started Windows in low resolution mode and safe mode. No change

Exchanged 3080 with a different 3080 today. Better initial start up but froze shortly after logging into Windows then slow after restart.

Reinstalled Windows 10 from local files. Current status, no POST

 

I am at a bit of a loss here and would appreciate any advice. I do have a second system that I haven't tried yet. If there's any additional info, I will be happy to provide it.

Ok a few things to unpack here. I should first mention I'm not 100% sure why your system is slow to boot but your configuration isn't the greatest. Using a 3080 paired to a R5 3600 is just CPU bottleneck city. I'd upgrade that CPU to something like a 5700X in the near future. Another issue is your 750W power supply. 750W theoretically is fine for your configuration but the 3080 has been known to have extremely short, but high, power spikes that can tip OCP on even 850w power supplies. If you have any overclocks I'd get rid of them as well.

No manual overclock, I can barely get into Windows with the 3080 installed
