Replying to a question from a buyer, an ASUS buyer suggestions consultant said that they don’t plan to launch any additional BIOS updates for his or her Z370 line of motherboards as they’ve already reached end-of-life. Absolutely, if ASUS has declared its Z370 lineup as EOL, then so have the opposite producers however the distinction right here is that the opposite manufacturers nonetheless provided help for his or her older merchandise to help new options whereas ASUS has fully deserted its prospects.

Each AMD and NVIDIA graphics playing cards at the moment help Resizable BAR expertise on boards which have the function enabled. At present, Intel’s 500/400-series and AMD’s 500/400 collection are formally titled for Resizable BAR help however as said above, board makers are providing BETA BIOS for the older Intel 300-series motherboard lineup.

Following is what customers have been posting over lack of help from ASUS for Resizable BAR on numerous boards:

Fairly weird, I’ve a Gigabyte Z390 motherboard and have had Resizable BAR help for some months now. I was an all out Asus man, however in recent times I’ve moved away from their model. I am discovering that Gigabyte are usually providing extra for comparable Asus cash on such periperals. – Zayd (

Utilizing a 3080 with a asus rog maximus xi and have been checking this tread each single day or any information concerning Bar help. Been loyal to Asus for over 10 years and whether or not we hear again from them or not, I am transferring on from Asus. That is very irritating and disappointing loosing out on free efficiency, particularly gaming in 4k. id_mew (ROG Forums)
Swimsuit your self. Goodbye ASUS and ROG merchandise. I’ll advocate everybody to keep away from their merchandise as a consequence of their lack of help in comparison with different manufacturers. And I ask everybody else to do the identical. We supported them with our cash and so they do not give a rattling? Nicely, let’s take all of the help again then! Unfold the phrase. This shall have penalties! Adhonaj (ASUS ROG Forums)
Nicely, that’s some very unhappy information. Nicely, I’d severely doubt if they do not replace Z370 they may replace Z390 both. Full BS on Asus half to not replace these board they’re 100 dreds of hundreds of those board nonetheless in use at present. Tregon (ROG Forums)
Sadly, all ASUS collection merchandise are already end-of-life. There isn’t any additional prospects prepared to purchase them. We do not care about our prospects solely their wallets. That sounds nearly proper. (ROG Forums)
No matter whether or not ASUS launches the Bios replace for the RESIZE BAR, this was my final Asus product, I’ll by no means purchase any sort of product from ASUS once more. It’s not the primary time asus has achieved this sort of factor, and probably the most critical of all will not be even responding to its prospects. Oh and simply to complete I used to be very silly in 20 years to have used merchandise all of them from ASUS. Goodbye ASUS Fred (ROG Forums)

The expertise is not going to require you to put money into a PCIe Gen 4 platform as it is going to be supported by PCIe Gen 3 too. BAR primarily defines how a lot discrete GPU reminiscence house might be mapped & at present’s PCs are sometimes restricted to 256 MB of mapped reminiscence. Each GPU producers declare that they will entry the entire GPU reminiscence, eradicating any bottlenecks to permit for quicker efficiency using resizable BAR.

Now in ASUS’s protection, neither Intel nor they themselves said to supply official help on the older Intel-300 collection motherboards. Even NVIDIA listed solely Intel 400-series and past would help Resizable BAR however you see, that is not the purpose right here. As soon as once more, the truth that others are doing it no matter a few of these boards being three years previous exhibits that ASUS does not care about its earlier prospects regardless of their merchandise costing a hefty premium over different manufacturers. ASUS has lately misplaced its market share to ASRock in Japan and it appears to be like like this sort of help for its PC-centric merchandise is not going to assist them in any respect.
