Ryzen 5 1600 with 2400mhz ram enough for streaming?

sbstajin123 · Jun 11, 2018

im new to pc gaming and i want tp stream games like pubg and fortnite, i want to know if 3000mhz ram speed is a must, or if 2400mhz will do the work just fine

3000 is much better than 2400, but diff between 3200 and 3000 is much smaller.

I will get 3200 if I can. What budget do you have for the whole build? 2600 will be better too. Living in US? Any components you already own/have in mind?

I´m from Mexico i have 17,000 pesos which is 834 dollars, the components are a bit more expensive because of taxes and stuff so im trying to save some money. I dont have any components yet, im going to buy the whole build all at once.

so 2400mhz is just not enough for streaming?

Are you willing to overclock? I bought 2400 cl15 memory and I have it running 3200 cl16 1.35v on x470 with a 2600...

2400 will work just fine either way.. but you should be able to overclock it no problem. go for some cheap Gskill Ive had good luck overclocking there memory. also make sure your buying 2 sticks no matter what. dual channel 2400 is faster than single channel 3200...

Im getting 16gb ram (2 x 8) 2400mhz so ill be rocking dual channel, i have my doubts on the ram speed thats why i want to know how much would ram speed affect my stream, so you recommend overclocking 2400 mhz? wouldnt that damage the ram?

vapour · Jun 11, 2018

in that case, 2400 is fine, just you need to accept several FPS lower than 3200

people run 1.5v, but I say at 1.35(stock for a lot of kits) is safe OC voltage and should last as long as your kit would stock. Just don't expect super tight timings. Just set the memory to 3000 or 3200 the voltage to 1.35 and leave all the timings on auto. remember that there are only like 3 types of ddr4. The speed and timings are all binning and marketing.

It depends on the application (game), but I'm fairly certain that the majority nowadays leverage H.264 and H.265 encoding/decoding at the hardware level directly on the GPU. Meaning, RAM speeds won't have any effect at all. It might, imperceptibly if all encoding is done in software however, but I'm sure CPU cycles will primarily be your bottleneck.

Hardware video encoding goes by several names depending on the GPU, but here are the top three listed.

Intel - Quick Sync
nVidia - NVENC
AMD - VCE (Video Coding Engine)

stdragon :

Your confused, you would use software(x264) when you have extra cpu threads to leverage, Hardware NVENC is GPU encoding. Memory Speed directly effects ryzen CPU performance that's why hes asking.. streaming on my r5 2600 compared to my i7 2600k its like night and day, I can hardly tell I'm steaming...

Dooop805 :

No, you are, frankly.

Dooop805 :

Negative, and absolutely incorrect! Specialized instructions sets that perform task in hardware will be vastly superior in performance and efficiency compared to a general software-only process. Think of modern systems having a tiny pocket of ASIC (Application Specific Integrated Circuit) that does one thing only, but does it really really fast! Down side is that it takes up valuable die real-estate on the chip that could otherwise be used for more general purpose operations. Yet, the market has determined that it's worth the cost to implementing dedicated encoding/decoding hardware.

Dooop805 :

Again, that depends on WHERE the application is leveraging the encoding. Being that his R5-1600 doesn't have an APU, he therefor is using a GPU. If API calls to the GPU for H.264/H.265 encoding/decoding, that actually frees up CPU cycles with little to no impact on GPU performance as well.

Which brings up back to the OP's original question. Which RAM speed is enough for streaming?. The question is entirely moot if it's using NVENC to encode the video. To draw a comparative is tantamount to a car analogy of asking how much turbo boost will give better traction - it doesn't, you ask for tire advice, not one involving turbo chargers.

That said, the ONLY time RAM speeds would have a direct impact on video incode/decode operations is if it's being performed in software only (CPU), or leveraging the iGPU or APU on the processor die. But that's it!

Your talking about integrated graphics and hardware again. OP would use software(CPU) to stream. much faster when you have a 6c12t part.

and you agree^ ram speed matters when using software encoding w/ Ryzen.

You said "software" to stream, but neither you or the OP specified with what app.

Look, I'm not saying you can't, or don't stream purely with a CPU based codec, just that it's very inefficient to do so. And depending on the delta cost of going from say 16GB (2x8) of 2400 vs 3000 DDR4, it might start to look better by sticking with 2400, and putting that extra cost that would have been dumped into 3000 instead into a better CPU or next level up in GPU; say a non-Ti to a Ti series GPU.

Going back to the "software" for streaming, OBS (Open Broadcast Software) can leverage the GPU and iGPU hardware based encoders using either FFmpeg NVENC encoder or Quicksync encoder codec respectfully. If however you plan on using Steam In-Home Streaming, it will encode and decode in hardware using NVENC, iGPU (QuickSync), or the AMD APU (both on CPU die, and PCIe based GPUs).

Here's a video from Linus Tech Tips showing how much better it is to leverage QuickSync on iGPU vs a standard x264 software based codec.

Like I said, you really want to offload that CPU as much as possible. If the hardware based codec is available, use it. Otherwise it just stays dark, asleep, and unused. Don't make the CPU work any harder than it needs to.

Here's Paul (Pauls hardware) talking about his streaming settings with ryzen and why.
