What kind of RAM should I look for using a Ryzen 3 2200g?

This is the CPU and motherboard I'll be using.
I know the faster the better if one uses the iGPU (I will for awhile), but from what I read of Tom's Hdwr review on the Ryzen 3 2200g, there is a speed limitation anyway:
2 DIMMs - Single Rank: up to DDR4-2933
4 DIMMs - Single Rank: up to DDR4-2133
2 DIMMs - Dual Rank: up to DDR4-2667
4 DIMMs - Dual Rank: up to DDR4-1866

Initially, I will be using 2x4GB, but when I can afford more I'll be using 4x4GB. If I read the chart right, it appears that anything over 2133 or 2400 MHz RAM is a waste anyway. I'd like to hear someone else's thoughts.

Totally separate question...
Can the iGPU be used to run one display while a graphics card runs a 2nd display? Or does the iGPU output become disabled when there's a card in the PCIe x16 slot? Thank you.

Faster RAM is better for the entire CPU not just the iGPU. Diminishing returns kick in at around 3000 afterwards you start paying a lot more for not as much improvement. So the answer is really as fast as you can afford.

You can but iGPU is disabled automatically when you install a GPU. There's not a real good reason to do this though. Any GPU can handle running two displays at once.

I assume, given sold as a bundle, the B350 board has the latest BIOS installed.....

Are you pairing with a GPU initially? Or just planning ahead? If you're using a discreet GPU, the 2200G makes very little sense.

That lists "official support", FWIW. Although Ryzen chips are more picky on going >official.

In theory, you're correct. Using 4DIMMs, you'll be limiting yourself to 2133MHz in the best case, 1866MHz in the worst.
Depends whether they're single or dual rank modules.


I don't know how flexible that memory support is.... as it's the IMC. Some overclocking may be possible, but I can't imagine 2133MHz single rank DIMMs x4 is going to OC much, at least not beyond 2400MHz.


If I were you, I'd start with 2x4GB ~3000MHz range.

If/when the time comes you need/want to add some additional RAM, sell the 2x4GB kit and replace with a 2x8GB kit of similar speed.



The implementation of iGP + discreet to drive multiple displays varies from vendor to vendor.

While the ASRock board may allow you to do so, I can't think of many situations where it would actually make sense. Using the iGPU to drive a 4th, 5th monitor etc (when the GPU cannot allow further displays) can make some sense..... but a 2nd display.... just run it from the GPU.

Ideally you want 2 DIMMs, 3000+ MHz. Those speeds are just the official rated speeds from AMD, you can run higher speeds (they're just technically considered an overclock).

You should be able to run one display of the iGPU and another of the dGPU. I don't know why you'd want to though, assuming that the 2nd monitor won't be running anything graphics intensive on it there will be no performance impact to running both of the dGPU.

Wow, lots of replies. And quick! Thanks to all. It appears the consensus is to go ~3000 MHz on the RAM in spite of what the review said then. If that is the case, then by OC the RAM I can improve on the iGPU performance?
I won't be able to add a gfx card (1060? 580?) until I save up more money. All my gaming is at 1920x1080, btw.

Most importantly, the ASRock AB350M Pro4 AM4 will not boot with the AMD RYZEN 3 2200G.
I have purchased several units from Newegg and a BIOS update is required and to perform the BIOS update you need to have a previous Ryzen generation CPU.

Now the RAM, personally I will go with 2400MHz - 3000MHz which by personal experiences have work without issues.
Mixing different RAM kits could pose an issue, so I would go with a 2x 8GB kit or 4x 4GB kit form the start.

Potentially, but not a hard & fast rule. Should run a little cooler though, without the iGPU enabled.



True, but it's going to depend on the specific modules used.
4x dual rank modules (as a worst case, for example) aren't going to get to those kinds of speeds with the additional strain on the IMC. 2x Single ram modules should be capable of 3200MHz, but 4x dual rank..... I'd be surprised if you could do more than 2133-2400MHz without issue.

Wait! The sales page for that board says it is Ryzen 2000 ready. http://

Not without a BIOS update.



It does...

As I mentioned

I assume, given sold as a bundle, the B350 board has the latest BIOS installed.....
Click to expand...

Given it specifically states "Ryzen 2000 ready" and is being sold as a bundle with a 2200G.... it's reasonable to assume it has the latest BIOS and will support it.

There's still a chance you'll be sent a "bundle" with an old revision of the board though.

You will think that right!.
By the way, I got bundles from two other vendors and they all had a BIOS that were not compatible with 2200G/2400G.
That is why AMD stepped in and it is loaning older CPUs "boot kit" so you can boot, update BIOS and be able to use your new CPU. Just make sure to type Boot kit Required in the Problem Description field.
