Question Resizable BAR option

[Soj1337]

Hey peeps, I just built my first pc and so far it's working really well, I just wondered as I'm currently optimizing and tinkering with stuff, if it's worth enabling resizable bar as people say it's a good boost to some games.

I've read mixed opinions though where some people say it causes negative FPS instead. Anyone have good experience with this feature?

I'm running a 5600x 3070, on an MSI b550 tomahawk with 3600 ram.

You can turn it on and observe how it works for a while, if you don't get crashes you can leave it on, otherwise just turn it off.

Resizeable bar generally increased performance and should be on by default.....

When i tried it. it seemed to give nothing to marginal fps increases. It did however increase my overall CPU temperature by 5C and GPU by 2-3C

There's Resizeable Bar that's enabled in motherboard BIOS and there's SAM, AMD's Smart Access Memory, which uses the resizeable bar capability. You have to also enable SAM in AMD's drivers (I assume there's something similar for Nvidia) to use the resizeable BAR if it's available. Its performance uplift seems to be highly dependent on specific application or game and how they access non-resident assets. At any rate it doesn't seem to hurt to enable it so just enable it if you have it.

I personally don't put much credence in "some people who say" since most people don't perform well controlled comparative FPS studies. But reviewers, who do, are generally positive on SAM.
