Question Upgrading memory

[Zielstone]

I currently have a rx550, upgrading to a rx560 4gb OC. I have 8gb of 2400 ddr4, would it be better to bump this to 16 gb or switch to 8/16 gb of 2800? Running a ryzen 1500x.

Ryzen systems benefit from faster RAM up until ~DDR4-2933 to DDR4-3200. Make sure to check that it's compatible with the RAM manufacturer.
Ryzen is exclusively beneficial to faster RAM. With the exclusion of Ryzen's need for DDR4-2933+ in pretty much all cases more RAM > less but faster RAM.

So 8gb of 2800 is better than 16gb of 2400

How much better would 3000 be over 2800?

The 3000 version is 8 dolla4s more.

In your specific instance the 2800+ kit would show a tangible increase in performance but... in all honesty you're still better with 16GB of RAM.

How much better would 3000 be over 2800?

The 300 kit is right in the sweet-spot for the Ryzen chips infinity fabric latency. 2933-3200 is the sweet spot. Landing inside this range will give you a tangible increase in latencies with the CPU. Above that you can't tangibly notice a difference and the kits in that range are painfully expensive still.

Before I can suggest a RAM kit I would prefer to know what motherboard you have. You can refer to the Memory QVL for your motherboard or go to the RAM manufacturer's website and use their configuration utilities:
