Ryzen 5 2400G + Asus Prime B450 plus warning

[HCHTech]

Had a frustrating workstation build today. Had the above with 16 gigs of RAM, a Samsung 970 NVMe drive and an Antec Gold 650 power supply. Got everything put together, double-checked everything and fired it up to start the hardware testing. Got lights and fans, but no post beep and no video. I know Ryzens sometimes take a while to come up the first time, so I let it sit there, but 2 minutes later, it still hasn't posted.

Nothing looked wrong, of course, so I started by pulling both sticks of RAM and I got no complaint beeps. Tried a known good power supply, same answer. Tried adding a discrete graphics card, no change.

Tried resetting the bios by pulling the battery for a while, no change.

Tried disassembling everything and booting a stripped down assemblage outside the case, no change.

I pulled the processor, nothing was wrong there, no bent pins, all good. Remounted it again but no change.

Well - either it's a bad motherboard or bad processor - wonderful. Luckily, I had a Ryzen 1800X in inventory, so I installed that and it booted to the bios normally. Before I call it, I decide to update the bios to the latest version. The board had 4.03 on it and the latest offered by the in-BIOS updater was 6.04. I did the update and it booted again, so I reinstalled the original Ryzen 5 2400G and this time it boots up. I remove the discrete graphics card I had installed to run with the 1800X and it still boots fine using the integrated video.

So, this seems a bit unusual for a board to require a bios update before a supposedly-supported processor will be recognized, and more unusual for the symptom of this required update to be a complete non-boot!

Just to close the loop, I checked on their website, and the 2400G is supposed to have been supported since BIOS version 318. Apparently not so much. I think I'll set that 1800X aside so it doesn't accidentally get sold. Thanks for the unplanned fishing expedition, Asus!

That is one of the reasons I do not custom build anymore. You do due diligence and research everything and still have to update bios before the chip you spent all the time planning won't even boot the computer and have to buy a different chip to upgrade the bios. (If you don't keep spares)

You end up thinking you got a DOA board spend time and money doing RMA's sometime more than once and there goes the profit.

More business for people like me who keep up on things. I always have spare parts around so I wouldn't have had to go through all that BS. I would've just used a different board and shipped the POS back to the manufacturer. Let them update their own BIOS's rather than place that burden on us. This is one of the reason I have 5 main Intel boards I use and 5 main AMD boards. I would NEVER buy a board that doesn't support Ryzen Gen 2 out of the box. It isn't worth my time to flash it. I'll just choose another board that already supports it out of the box.

The point is, it's not a big deal to do custom builds if you've got tons of parts in stock. Dead PSU? Replace it. Motherboard not POSTing? Swap it out and test it later. Whenever one of our main boards are no longer manufactured I do some research and choose a replacement board and use that from then on.

Sounds a bit extreme... it takes all of about 5 min (including finding and downloading the BIOS file) to do a BIOS update on a modern board and the best time to do it is when there is no OS installed.

I agree it's annoying and any board marketed as being 2nd Generation Ryzen compatible should darn well support 2nd Gen Ryzen chips out of the box.... but it would take longer to pack the board up and send it back than it would to just flash the new BIOS.

the 2200G/2400G came after the initial onslaught of 2000 series processors, so, if the MB was distributed in March 2018, and the 2200G/2400G was released in June, for instance, there's easily a chance it was pre-2200G/2400G BIOS compatible....

Glad you got it fixed, however!
