[SOLVED] Will 3000MHz DDR4 RAM be enough for Ryzen 5000?

[Raven A]

I have pre-ordered a Ryzen 9 5900X to upgrade my PC. However, I read somewhere that "AMD suggests 4,000MHz RAM is the sweet spot for low latency and high performance ". I have 2 Corsair Vengeance 8GB 3000MHz sticks of RAM, and rather than upgrade that to 16GB of higher speeds RAM, I was planning on buying another 16GB of 3000MHz so that I'd have 32GB, but with this information it seems I may be better off buying 16GB of 4000MHz. My main goal with this new CPU is making sure I don't get CPU bottlenecked in games (with an RTX 3080 at 1440p) and 4K video editing (which is where the 32GBs of RAM come in handy).

What would you guys think is the best way to go out of these two, 32GB of 3000MHz or 16GB of 4000MHz? Would 3000MHz be a serious bottleneck?

It's not worth it to upgrade to 4000mhz.
Yes, you're leaving a few precents of performance, but 3000mhz is plenty.

Also, if you got 4000mhz ram, then wanted 16 gigs in the future you might have to limit it anyway since 4 sticks of 4000mhz is very hard on the memory controller, and aside from over the top motherboards with the best traces, you won't get to it.

I have a 3700x and RTX3080 and game at 1440k and occasionally 4K. I am yet to see a cpu bottleneck in my games.

I'd buy a 2 channel 32GB 3600 ram.

I have an intel i7 6700K currently, and it bottlenecks quite heavily with the 3080 unfortunately. GPU usage is at 50% in CPU heavy games. Thus, this upgrade is quite necessary.

I'd buy a 2 channel 32GB 3600 ram.

That is beyond my budget unfortunately.

Thank you for this information!

You said you wanted to be sure you wouldn’t bottleneck. My point is I don’t see a 3700x bottlenecking at 1440p & 4K, with a 5900x you have no worries regardless of RAM choice between 3000 & 4000mhz.

Yes, but it would still matter in a few years as gpu's get more and more powerful and become not as much the bottleneck, even in 1440p and 4k.

The 3090 in 1440p actually sees a difference between cpus.
give it 2 more generations and gaming will become more and more cpu dependant in my opinion.

I don't think anyone else mentioned it , adding a second kit of ram to your existing ram(even the same exact brand and model) may not work. The ram modules in each kit are tested and verified to work together. Adding a second kit may or may not work.

Interesting, didn't know. If they don't work I'll send them back and probably upgrade to higher Mhz.

I think my comment that my main goal is to prevent bottleneck may have been misleading. I meant that the reason for my CPU upgrade is to prevent bottleneck, and I'm very certain this won't happen with this CPU regardless of RAM MHz. But then I read that AMD recommends higher Mhz RAM than what I own. I don't think this would make the CPU sufficiently bad that it would bottleneck the GPU, but rather that I don't want to have a top of the line CPU that is severely limited by the RAM MHz, thus my motivation for this thread was to see to what extent it is a 'waste' to use my current RAM in conjunction with my 5900X. The GPU bottlenecking can be disregarded in that matter. But thank you for your clarification.

Agreed, I've had GPU bottlenecks before but they are getting more serious with every generation, simply because of the large leaps. Every new generation of GPU's seems to require a new generation of CPU. 50% GPU usage due to a bottleneck of what used to be one of the worlds best CPU's used to be unheard of.

Got it on what you ment on the RAM.
Well, as I said before, 3000mhz ram will maybe make your processor a few precent slower than say 4000mhz, but it won't "severely limit" it.

You would benefit by just getting 2 more 8gb sticks of some cheap ram and just have them run at the same speed as your old ram. This would give you 4 ranks so you can use interweaveing.

55$ for some on sale memory 2x8gb 3200mhz

150$ and get 4x8gb3600mhz cl16

200-500$ for 4x8gb 3800mhz cl14

Depends on what type of performance your looking for. I suggest looking at some benchmarks in youtube compareing 2 vs 4 ranks and also different speeds so you can see if the increase in money is worth it to you.
