3900XT and Infinity Fabric.....

[Southpawjoe]

Built this pc nearly 2 years ago and at the time the supposed "sweet spot" for the infinity fabric was 1800. I just recently did a full BIOS update to 4021 and was wondering if this had changed since the updates of 2 years ago. This is my current system:

Ryzen 3900XT
Asus TUF Gaming X570 Plus Wifi
Corsair Vengeance 16x2GB DDR4 4000 CL18

Currently have my ram set to 3600 and the infinity fabric to 1800. With my ram being 4000mhz should I now set my IF to 2000? It's been a while since i've built this since it was mostly a set it and forget it, but figured with a ton of BIOS updates stuff would be much better now.

1900 is a good spot to be if you can get there.
Not much has changed on the 3xxx series.

Dont think you will see difference real time but if you can run 2000 why not like Mr Scott says 1900 if not . I ran 2000 / 4000 more just nice to know i was lol

You have a good chip if that 2000/4000 was still at 1:1
Usually over 1900 changes gears.
