Big mystery

[Ghost2205]

Hi.

Sorry to bother you but I have big problem that I never encounter in my 30+ years dealing with computers.

I have bought Gigabyte GeForce 1660 Ti 6Gb OC with dual windforce fans.

After instalation card start to act crazy.

Crashing games,slow win boot and so and so.

After that I got Palit 1660 Ti Dual.

Same thing.

My configuration:

I3-8350K non OC water cooled

TUF Asus Z370 Plus Gaming

16 gb Crucial Ballistix DDR4 2666 Mhz

OCZ Vertex 4 256 gb SDD for win 10 only

WD Black SATA III 500 Gb

WD Green SATA III 1Tb

Sound BlasterX AE-5

Antec TruePower Classic 750W 

 

Asus Phoenix 1050 Ti works great in PC but any 1660 Ti do not want to work normally 

I hope you can solve this problem.

All hell break lose when I use 8 pin to power 1660 Ti.1050 Ti working fin or even better.

I get 57-71 fps in WoT with 1050 Ti all the time.

Only problem is when I try 1660 Ti and connect 8 pin in card.then broblem starts.

Is it possible that PSU is about to give up?

Did you remove drivers with DDU and install fresh ones with the 1660ti?

yes.

Done every possible thing I could think off.

1050 Ti working great but 1660 Ti with 8 pin connected bring hell when I start the games or open apps.
