Help Needed With Resizeable Bar

[madizema]

I'm currently running an MSI Z370M Mortar with 8700k and RTX 3070

Updated my motherboard to the latest 7B54v1A2(Beta version). Enabled Above 4G memory & Resize Bar Support still my GPU is showing no resizeable bar...
Can anyone please help me with this? PLEASE...

I don't think 2070 supports resizeable bar

 

Even if NVIDIA actually made it so 2000 series able to use the feature when I wasn't not looking, it most likely requires a vBIOS update.
Even the early releases of 3000 series needs a vBIOS update to support resizeable bar

 

Don't worry though, you don't lose much.

Even on 3000 series it's like... 5% increase max.

Sorry I meant to write 3070

If you've got an early enough card (judging by the fact it doesn't say LHR after the 3070, I'd say that's rather likely), it might not have a ReBAR capable VBIOS, in which case you'd need to update it. Each of the GPU manufacturers put out instructions for how to do that and check that your card does in fact have a ReBAR capable VBIOS. Look up your specific GPU manufacturer followed by "resizeable BAR 30 series" and you should find the instructions. 

 

 

That said, I wouldn't lose sleep if that doesn't work. The 30 series just doesn't benefit from ReBAR much, if at all, usually only in the low single digit percentages. No where near enough to notice or put more than 20 minutes of effort trying to get working.

You probably need a GPU vBIOS update.

 

Also, you're talking about a 2070 but your screenshot shows a 3070...

What @RONOTHAN## & @191x7 said.
It's the same case for my early release 3060ti, which I'm too lazy / too afraid to flash (update).
Well that and I don't like the idea of needing to use Dragon Center to update it.

This is the current version of bios installed with Gigabyte Control Center as I'm afraid of doing it manually

I'm currently using Gigabyte RTX 3070 Gaming OC

You could flash the latest VBIOS (4th file), but really with NVidia ReBAR is useless, you should not bother at all

Idk about 4000 series, but yeh even on my 3080 12gb i agree that the perf increase between rebar and not is not worth the trouble and/or possible risk of vbios flashing.
