[SOLVED] B550 Phantom Gaming 4 CPU Question

[nagakura]

Hello

does this MB support other CPU than listed on the site:

https://www.asrock.com/mb/AMD/B550 Phantom Gaming 4/#CPU

eg would it support any 1600 or 2600 CPU?

In general if it's not on the list I would expect it not to run at all or I would at least expect problems.

If ASRock was confident that they would work well....ASRock would put them on the list.

are AM4 CPUs not generally compatible with the socket?

"Supports AMD AM4 Socket Ryzen™ 3000, 4000 G-Series and 5000 Series Desktop Processors* "

Same socket yes, but you still need BIOS written in such way to support each CPU model. Probably AsRock decided to cut the costs and not include older CPUs in the BIOS code assuming that almost nobody will buy new motherboard to put old CPU there.

 

[jay32267]

I agree.

the MB is neither new, nor are 2600 old

B550 is Ryzen 3000, and 5000 only. (except for the 3200g and 3400g)

aha. any technical explanation why is that? what is different vs eg 2600 ? PCIe4 ?

DRagor gave the answer above. There's only so much room in a 16 MB EEPROM to code for different CPUs. Sure, a 32 MB EEPROM is not expensive, but motherboards on the budget side have very small profit margins, so companies aren't keen on doing that for niche things.

And yes, three years old is fairly old in this context.
