Ryzen 5000 series reportedly not supported by ASUS on 400 series motherboards

Written by Neil Soutter on Tue, Oct 13, 2020 4:00 PM

Following on from the Ryzen 5000 series BIOS updates that have now been rolled out for 500 series motherboards, AMD confirmed that plans for an optional BIOS update to 400 series motherboards will still be coming in January 2021. However, it has recently been revealed that ASUS may not be supporting the new Zen 3 CPUs on their 400 series motherboards after all.

The recently announced Ryzen 5000 series will require a BIOS update on certain chipsets for optimal performance, and since the new updates are baked into the BIOS, it is up to the manufacturers themselves if they would like to add the support for their 400 series chipsets, which ASUS may not be willing to just yet.

According to one Reddit user, customer support directly told them that ASUS has no plans to support the new Ryzen 5000 series on their 400 series chipsets. Since this is not an official press release from ASUS themselves we can’t exactly confirm the report, but is useful to raise awareness for those rocking a 400 series motherboard from ASUS.

The Reddit user, known as u/Eroji, contacted customer support on the phone to ask if ASUS would be providing an update for the ROG Crosshair VII Hero X470 in order to support the new Ryzen 5000 series, to which the representative said no.

They then further followed up by asking the information to be confirmed by the engineering department in hopes of just another misinformed representative situation. However, they then received an email that said: “According to our engineers, We have no plans for the Crosshair VII Hero to support the Ryzen 5900X, please purchase Crosshair VIII Hero and any [ASUS] B550 motherboard that will support Ryzen 5900X and 5000 series processors.

So there you go, looks like ASUS won’t be providing any support for the Ryzen 5000 series on 400 series motherboards. Hopefully this will spark a response from ASUS to officially comment, and with enough feedback may even change their minds.

What do you think? Do you have an ASUS 400 series motherboard? Will you be waiting for an official update or will you be buying a new 500 series motherboard now? And will ASUS be the only one who won’t provide support? Who else do you think will be the same? Let us know your thoughts!

Do you have an ASUS 400 series motherboard?

Are you looking to upgrade to a Ryzen 5000 CPU?

I think the staff likely made a mistake as no way would AMD not support them as remember the backlash to make AMD do their Uturn in the first place.

If true(and I have no reason to believe it isn't), I think Asus might end up backpedaling on this after the backlash this is going to generate.

I hope it does, the Crosshair VII has a 32mb BIOS chip as well so i don't see why they wouldn't. Unless they are too lazy to update it on the 400 series. I mean i got mine for free so i can't complain but spending another 200+ for a x board for a 5000 series cpu is a bit ridiculous.

I did come across this though and they apparently reached out to Asus and that's the response they got.

Yeah seems to me that some wires got crossed and someone got incorrect info from customer support..... I also can see no reason why ANY vendor would choose not to make it available when AMD releases it, they would just open themselves up to an unneeded wave of hate....... the only place I think it might make a little sense is in the case of the ultra cheap super entry level boards that someone might have in their office PC...... and even then, if it can be supported, then it should!

Even gigabyte and msi x570 boards have a 16MB BIOS chip, the fact that asus uses 32MB mean they're looking for future support. They're customer support are pretty hopeless though.

Yeah with a 32MB EEPROM they should be able to add support without dropping support for current gen CPUs, unlike many 400 series boards.
edit: Btw just a little correction, MSI X570 boards have 32MB EEPROMS, but the Gigabyte boards do only have 16MB

yea sorry meant to say x470 boards from MSi. Crazy that gigabyte uses 16MB even on x570, crazy.

agreed.... I wonder if it caused Gigabyte to have to cut some BIOS features from their X570 boards to make room for the new CPUs.

I know they have dual bios chips if i recall correctly, my x370 failed within 4 days so i bought my crosshair vi then got given a crosshair vii by elmor on asus forums. Pretty sure mine had a dual bios chip so i that 16mb x2 or is it 16mb each and not combined.

One way to find out is to download and extract a BIOS for your board...... if the file size for the BIOS image is 32MB, then you have 2 32MB EEPROMs, if it's 16MB, then you have 2 16MB EEPROMS.

The CPUs that were brought out to the light are all too expensive for my purposes. I can see HC gamers buying them but I'm hoping they lower the clock and bring out cheaper CPUs.

Cause currently, I have no need to upgrade anything. Everything runs smoothly at 1080p on High so I'm content. When there is a budget CPU that packs a punch, I will upgrade, before that. No thx

Well yeah, you need a whole PC upgrade for a new CPU to make a difference, and for a CPU to pack a punch at a low price, wait for the next couple generations.

I upgraded from a 4770k because I could feel it lagging for my general use case. Even in gaming I felt the 4c/8t were holding me back since I tend to multitask. Can't imagine what it must feel like with the i5 o_O

I think they will, the non X version of the 5600 and some variant of the 5700 will likely be coming down the road...... They will probably still be sold for a $50 premium over Zen 2, so probably something like $250 and $380 respectively, but I do think prices on all Zen 3 will probably drop under MSRP after a while.

hi @protosangelus fella, with the almost same CPU as mine. In order for us to upgrade to new CPU we need to upgrade all. Mobo/ram and CPU which might be more expensive than we thought all tho CPU's are usually less expensive than GPU. The only think we can upgrade is the GPU but if we get even better gpu than mine i like 1660 or so i think there'll be bottleneck problems with my CPU. So thats it.

new PC probably not. Just new mobo, cpu and ram for me unless i sell my entire PC as i plan to in some point of the future. A question: Does mother board* that supports DDR4 supports DDR3 as well or not? I think only supports DDR4.
