No post, no codes, no fanspin!

[Toothless]

Alrighty, here's one I'm actually stressed about.

So my wonderful (not) new x470 stuff came in yesterday and I started building it last night. Simple board/ram/cpu swap and we good right? No.


Hit the power button, CPU fan does not spin, no bios codes, no display, nothing but case fans and HDD noises. I've taken out the ram, removed everything but cpu, unplugged everything, still nothing.

Board powers but does not attempt to boot without cpu so at this point I'm wondering if I got one that doesn't actually support 3xxx chips, making me have to buy a 2200g or something to bios update.

Any ideas?

If it in a case take it out. But I'm sure you tried that

Asrock Taichi Ultimate x470 is compatible with Ryzen 3000 series with the latest BIOS.

Remove the CMOS battery, reseat motherboard and CPU. Loosen motherboard and CPU cooler screws.

If you have another AM4 CPU, try it, and make sure the BIOS is updated to the latest version.

Actually didn't.. I'll give it a go in a bit.

No other AM4 chip in the house besides the 3900x that I know I can't use. I've seen people with the same chip as me be unable to use it unless they had bumped the bios version up but since I can't do that, well, I'm SOL.

USB BIOS Flashback
Select motherboards are designed to support “USB BIOS Flashback,” which allows for BIOS updates from a flash drive—even if the current BIOS on the motherboard does not have the software code to boot a new processor. Some motherboards can even update the BIOS when there’s no CPU in the socket at all. Such motherboards feature special hardware to enable USB BIOS Flashback, and every manufacturer has a unique procedure to execute USB BIOS Flashback. Customers are encouraged to determine if their motherboard supports USB BIOS Flashback and, if yes, follow the update steps described in the motherboard’s support documentation.

Supported on Taichi X570 but not yours.

Just borrow AM4 CPU or SPI programmer from someone, or buy a used cheapest one from this list.

AMD loan out a 2 Series CPU so you can update the Bios.
Check their website for details, they even pay for postage.

scroll down to short term processor loan

I was thinking this, but I thought of the wait time in terms of shipping.

Ended up dropping the board off with the local tech shop and they'll have the bios updated by pick up. I'll do an update for the thread then.

I'm impatient that way too, I ended up going to my local PC shop and getting a 200GE to do the update myself.
I figure it's handy having a cheap processor around for testing purposes.

I was thinking that too with a 200GE, but I'd probably only do it if I had two or more AM4 builds to use it on, like my collection of Haswell chips and boards.

Contact Asrock as well. I dont know why you got an older board, but most sellers here have updated the bios and shipping latest ones.
I read somewhere that some BIOS chips cannot physically support the larger BIOS size for 3 series. So please reach out to Asrock on this, as you may need a new bios chip.

That's an interesting find. I've found people who run 3xxx on their AsRock boards with no issues minus the initial bios update being required. I'll have to look into this of the shop can't get it going.

I don't recall this being an issue for ASRock. ASRock likes using the 32MB chips. The 16MB BIOS chip "woes" were almost exclusively an MSI issue, which they later resolved by launching the MAX line of the exact same boards with a 32MB chip. To this day, I'm not sure if they really ran into issues (which reflects poorly on their Click BIOS design more than anything, that it needs to be gimped to fit into 128Mb) or invented the whole fuss to sell their MAX boards, because a smattering of Gigabyte 400-series boards were equipped with 16MB BIOS chips and they haven't had compatibility issues (though the lack of quality in GB's UEFIs is really not a secret). My Aorus Pro Wifi is an example of a 16MB board, and it's gone through several revisions just fine. To be fair, the MAX boards also advertise out-of-the-box support for Matisse, so there's that.

That's one thing I hate about the whole backwards compatibility thing, in combination with the fact that B550 was delayed for so long, meaning B450 was still in production. You never know if you'll get old or new stock, because by this time something like half the BIOS revisions for some B450 boards support Ryzen 3000.

Ah, BIOS size varies from manufacturer to manufacturer, some may not be as efficient as they claim haha.
