RAM speed and gaming with Ryzen APU

1 : Anonymous2021/04/01 15:48 ID: mhy58u

I have built a SFF mITX computer with an ASRock Fatal1ty B450 GAMING-ITX/AC and a Ryzen 3200G with 16GB of DDR4 3200 ram. I have not had much luck on RAM OC'ing. How much difference would it make in actual gaming with a 3600 kit, and CL16 vs CL18 at that. It will be running Win10 Pro, and mostly playing older emulation, some brawlhalla, maybe some GTA V and San Andreas, the type of stuff you can sit on a couch or lay on a bed and play with a controller. The serious KB/Mouse gaming will happen on my main gaming rig. I do plan on getting a better APU when it is available/reasonable - hopefully 5000 series if it actually happens - so this can be had in mind. I have tried to search for this info, but most of what I find people are using a GPU, so it is less relevant I think.

TLDR - Ryzen APU gaming performance difference between DDR4 3200, and 3600 CL16/18?

The IMC on your 3200G might not even be able to do ddr4 3600. Even if you could do 3600 with the same timings, that's only ~12% increase when you're not cpu bound. This is like 3-4 fps if your baseline is 30fps. Not really worth the hassle, imo.

The best thing to do would be to bump your ddr voltage up to 1.4-1.45v, see if the sticks will overclock anymore than 3200. Then, tighten up the timings.

would this be the same with a 4700g or 5x00g if it were to ever exist and be attainable? sorta forward thinking. 12% increase sounds like at the very least smoother and less drops.

The higher ddr4 speeds will be slightly easier to get with a ryzen 4000 or 5000 apu.

Also running a 3200G atm, memory overclocking on these chips is pretty abysmal.

i have watched videos on youtube where they get 3600mhz easy, and game on it with 3200G and 3400G and i have not been able to even finish a benchmark, lol

I have a 3400g and keep crashing AFTER 3200mhz with XMP profile or even the ryzen ram overclock tool that people use.

My son has a 3400G and has had issues with memory overclocking. it is weird though it passed a full test with no issues, but as soon as you play a game or run a benchmark it would have issues, crashing, stuttering, artifacts, hangs... have not pushed the 3200G nearly as hard, yet.

I went from a 16GB 3200MHz CL16 kit to a 16GB 3600MHz CL16 kit on my living room 2200g system and for me, the performance increase was noticeable enough to be worth it. Especially since it was stable out of the box and that new kit I got was around the same price I got the original one for.

That performance bump will really only be noticeable at 1080p and above on the APU though, because for APUs the RAM speed really only helps the Vega igpu for the most part. So if you're using the sffpc the same way I am (bc you said it's not your main rig) I'd say it's definitely worth making your RAM faster.

This is literally a bedroom HTPC. I have a gaming rig with 5800x, and a living room HTPC with a 1600x, this was so I could do stuff in the bedroom, without having a full size computer in there as my wife is annoyed with how many computers I have, lol

Gotcha, I figured as much. I do the same with an HTPC in living room to stream/locally play my steam games on my TV. Again, to reiterate what i said, high speed RAM kits are definitely worth it if you play at higher than 720p and want to get more out of the iGPU. I never regretted buying a new 3600MHz CL16 kit for my box and re-using the previous RAM in a different PC.

Good luck though man! May the OC'ing of your iGPU clocks be good lol.

3600 will probably be better, but you're pretty unlikely to hit 3600 on a 3200G.

I'd say considering i've had and sold several of the exact same board with a 3200g, 3600mhz is certainly manageable, at least in my experience with the asrock. In ferms of a performance uplift, it's not going to be all that much over 3200mhz in my experience.

I think the investment would be better suited for a dedicated gpu or upgraded APU down the road soon.

I am debating buying faster ram, and i would add this other kit to one of my other computers i guess. Just wanting to know if it will make a noticible difference on the iGPU performance for Ryzen APU, i know the RAM speed is relevant, but not how much. i have not been able to get a RAM overclock over 3333 to stay on in any benchmarking. if i just overclock and use the computer normally i can go higher, but it dies in a benchmark test, so obviously not stable.

It's definitely not worth the price difference. If you have $100 to spend on a new RAM kit, just get a used 570 off eBay instead.
