Resizable BAR. What is it?

[Baldbloke]

I had a quick google. It seems to allow gpu memory access from the cpu.
But only in certain games and on certain hardware.

I play Automobilista 2 (badly) and Assetto Corsa (very badly) in VR. Almost exclusively.

Would this Resizable BAR thingymabob be of any use to me and would I need to enable it in settings/bios/game?

I have a Ryzen 5 3600 and an rtx 3080ti.

Muchly thanks in advance.

Thank you so much for the replies and info. I downloaded GPUZ. It states Resizable bar is disabled. So I had a look on MSI site. Briefly read a document there and it suggests updating Vbios. Erm, nah, Not with the price of gpu cards these days. I'm not willing to fiddle with Vbios. I'll leave it be.

No.

The clocks went back, its dark & ******* down with rain, I have a dentists appointment on Weds that will likely involve pain, Ocado has sold out of my favourite chocolate spread for Thursdays delivery & I had to do a BIOS update to get resizeable BAR working on my Z390 board & BIOS updates stress me out, which resulted in absolutely ZERO perceivable difference to performance with my 3080.

Expect more grumpy posts today.

Does that answer your question..

I hate to make you jealous but, The good news is.... I'm having a great day. Oculus just sent me an email stating I was level 3 contributor (I've made two posts!

And... I got a picture of a BADGE! Can one mans day get any better than this? Wow!

It was only to be done on early 3xxx cards if you bought a later one it was already enabled ie if it was purchased after 31/03/21 then it will have Resize Bar enabled in the GPU firmware.

Oh happy days. I just needed to enable it in motherboard bios. Thank you. Haven't tried it yet. Will it make a difference? Dunno, but.....

Resizable BAR? its just another e-peen box to be filled in GPU-Z, thereby relieving the cards owner of an overwhelming sense of terror & dread of FOMO...

Now I can stroll down our local high street, exuding such confidence, women will be able to tell just by looking at me "He's got Resizable BAR enabled, I bet. Ooh ".
