RESIZE BAR for Z370/Z390 chipset

[fred16]

Good afternoon,

I would like to know if a BIOS update will be released for the z370 / z380 motherboards with RESIZE BAR option?

Thanks
greetings

Hi,

Technically it is possible, Intel platforms since Haswell can do it. As for the support of the Ryzen 5xxx CPUs with 4xx series chipsets, it is up to ASUS to consider (because let us remember it anyway for certain, it is not a non-profit NGO ...) if it is more interesting to make shine brand image with gamers by activating this feature where possible (despite most motherboards being mostly EoL), or rather artificially restricting this feature to the latest motherboards to sell more.

In addition, to date this feature only affects new AMD graphics cards, knowing that over 70% of gamers use NVIDIA graphics cards (Steam statistics) and that NVIDIA is working on it only for his RTX 3xxx series GPUs, there is no point in being rushed for the most part.

To date here are the chipsets which have BIOS with BAR/SAM :

AMD :

- 5xx series chipsets (Example : https://rog.asus.com/motherboards/ro...helpdesk_bios/)
- 4xx series chipsets (Example : https://rog.asus.com/motherboards/ro...helpdesk_bios/)

Intel :

- 4xx series chipsets (Example : https://rog.asus.com/motherboards/ro...helpdesk_bios/)
- X299 chipset - Beta (Example : https://rog.asus.com/forum/showthrea...ge2#post824020)

I think that it was not bad for both INTEL and ASUS to offer this treat to their customers since Intel has been failing so much with security problems in its processors that updates to try to solve the problems take away performance.
It would be fair for them to please the customer.

Would definitely like to see Resize BAR offered in Z370/Z390, as those mobos are still running abundant in use.

I bought high end motherboard M8 Hero so I would like and hope that they bring these kind of hidden features via simple bios update now when its relevant tech next year. That would be good support for these expensive products.

Z370/Z390 are EOL

Just to add some of the rumours I've heard, Nvidia is going to implement a SAM-like feature with its new 3080 TI in Q1/21 too. And they're (hopefully) also planning to backport it towards the 3080/3090, whereas this likely will require a GPU BIOS update also.
Anyhow, would be really great if Asus Z390-series of motherboards will enable support for BAR. Thanks!

I think the RESIZE BAR / SAM should reach the RTX2000 / 3000 series and also the Z370 / Z390 / Z490 chipsets as they are practically identical technologies, there is no excuse to say that it is not compatible.
And I think it would be a way for ASUS AND NVIDIA to prove that it is worth buying products from them, as I have already bought about ten computers always equipped with NVIDIA AND ASUS in my entire life, and there must be many like me.

Asus has started to support Resizable bar for 1st generation AMD processors.
We expect the same dedication within the intel 8th and 9th generation.
