FPS and refresh rate

[DEL 707]

I have a Gigabyte Radeon RX VEGA 64 WindForce OC 8GB HBM2 PCI-Express Graphics Card playing on a MSI Optix G24C 24" 1920x1080 VA FREESYNC 144Hz 1ms Curved Widescreen Gaming Monitor.

I don't run any kind of Vsync, or freesync. For some reason freesync causes fluctuating brightness.

My graphics card absolutely takes off in some games, and gives me some nasty coil whine, especially in menus etc.
I thought I'd use the radeon software to limit my FPS to 144. But I've read that I should actual limit it to 90.

Shouldn't I be aiming for the limit of my refresh rate?

From what i've been able to gather the vega and polaris cards from gigabyte hasn't been stellar. BUT! you are not out of options. You should look into undervolting. You won't loose performance but you will reduce the heat if done correctly. Most vega cards are insanely overvolted from the manufacturers side. Example would be my nitro + vega 64 which runs at stock 1.2v. But it only need 1,0v to sustain the same clocks.

Thanks for the reply.
Yes this Gigabyte has been the bain of PC with it's crashes.

I've been trying to find other Gigabytes users to see what voltages they use, without much luck. So I'm kinda winging it with not much luck.
