Hi,

Just purchased the Ryzen 5 1600 and bought the Gigabyte AB350 Gaming motherboard to go with it. However, the motherboard shipped with the original BIOS and I have no way of updating it to the latest to get it to post with my CPU. I contacted Gigabyte and they said I have to use a Ryzen 7 to update the BIOS or send it to them to update, or send it back to the retailer for a refund. I decided on the latter. However, I can't seem to find a board on the market which ships with Ryzen 5 BIOS support. Am I the only one having this issue, or am I missing something?

Thanks

A new BIOS will often come with new version of the AGESA code in it, which is used on AMD systems to properly initialize all of the CPU cores, memory, and HyperTransport controller.

Notice in the BIOS update notes for the BIOS versions required to support newer Ryzen CPUs, AGESA has been updated. In fact, sometimes that's the only change made.

While the R7 and R5 may be based on the same original die, there are enough changes that the AGESA must recognize the new processor.

This isn't something new for AMD. A BIOS update was required for the FX 8370 CPUs, despite their likeness to the FX 8350 CPUs.

If the CPU support list doesn't say your processor is supported until an AGESA update, I wouldn't assume it's going to boot, not that it...


I got a B350 MSI Mortar under a 1600, and it took forever to get a post. With one stick of ram in the A1 slot I was finally able to flash the bios. And it still hates this corsair vengeance 3200 ram, which i can only get to 2933. I got an overclock of 3.7 - I got it to 3.8 but too hot on the stock cooler.

I was about to send it back a couple of times, and maybe I just got lucky. But I plugged and unplugged all the ram in each slot like a retard - cleared cmos a couple of times, and finally got a boot.
 


The slots to use are A2 and B2 if only using 1 or 2 sticks of ram, this might be why you are getting slow boots, its in the manual.
 


Yeah I heard they can take ages to boot that's why I tried to be as patient as possible with my B350 Tomahawk and I also tried that method with swapping the RAM into all the different DIMM slots but still no boot. I think I just need to use a R7 to update the BIOS.
