似乎RAM每天都在变快，但更快的RAM重要吗？购买 3000MHz 是否有意义，或者像 2400MHz 这样的设备是否足够好？
让我们来看看高频RAM对您的系统的实际作用，以及它是否值得购买。读完后，您将了解更快的RAM有什么作用，以及购买它是否有意义。
RAM 和 RAM 速度简介
在讨论RAM速度之前，让我们先看看RAM的用途。
RAM从硬盘驱动器中获取数据，包括程序和游戏的数据，并在您使用这些程序或游戏时保存数据。这是因为RAM内存比标准硬盘驱动器(RAM)甚至 SSD(even an SSD)快得多。RAM保存的数据随后被馈送到CPU(the CPU)。
有了这个推理，更快的频率RAM(RAM)意味着更好的性能是有道理的。但最终的结果并不是那么清晰。问题是，无论您的RAM可以多快地将数据发送到您的CPU，都会有一个限制，您的CPU根本无法足够快地处理所有这些数据。
值得庆幸的是，处理器制造商已尽可能轻松地找到最适合其CPU的速度。(CPU)您所要做的就是在线查看每个芯片组的规格。
例如，英特尔(Intel)建议他们为英特尔(Intel)i9-9900K支持的最快RAM是(RAM)DDR4 2666MHz，而AMD表示他们的 Ryzen 2600 CPU(CPUs)支持最高DDR4 2933MHZ。那么为什么RAM制造商销售更快的RAM呢？这是因为通过超频，仍然可以达到这些速度。
这意味着什么？好吧(Well)，如果您追求工厂体验并且不涉足超频，那么在Intel上高于 2666MHz或在Ryzen上高于 2933MHZ没有任何好处。
所以如果你是那种不接触 BIOS(touch the BIOS)的人，你应该选择上面提到的MHz限制。如果您发现在更高的速度下价格相同，您可以走得更高，但您实际上不会达到这些速度。
超频以获得更快的 RAM 速度(Faster RAM Speeds)
现在，如果您想在BIOS中超频或乱搞，那么寻求更快的RAM速度可能是有意义的。通过在BIOS(BIOS)中打开 XMP ，您可能会达到更快的RAM速度，但要了解这只有在您拥有受支持的主板(you have a supported motherboard)时才有可能。
最终结果是在打开 XMP 后选择更快的RAM速度有助于提高某些游戏的帧速率，而在其他游戏中几乎没有明显差异。(RAM)它似乎因游戏而异，但许多游戏确实获得了更好的最低帧速率。
根据Linus Tech Tips的结果，我们可以看到差异并不令人难以置信，但肯定存在差异。在某些极端情况下，我们所说的最小平均帧数增加了 20 到 30 个。在其他一些情况下，它只需多出 5-10 帧。
非游戏相关任务（如视频编辑）的基准很难找到，但很可能是同一个故事：在性能方面的微小改进，以实现更快的RAM速度。
你应该购买更快的内存吗？
考虑到这些信息，您可能仍然想知道是否应该购买更快的RAM。好吧(Well)，如果您愿意超频您的RAM并且不介意解决任何出现的潜在问题，那么这是值得的。
但只有在价格上涨幅度很小的情况下才值得。例如，在某些情况下，亚马逊(Amazon)上的 2x8GB 2666MHz 套件的成本可能与 2x8GB 3000MHz 套件完全相同。在撰写本文时只需(Just)70 美元。
但当RAM成本更高时，我不会推荐它，例如，现在 2x8GB 4266MHz 套件的价格为 269.00 美元。额外的 200 美元最好花在升级的CPU、GPU甚至更多RAM上。
概括
总之，只要您使用 2666MHz 或更高的频率，在尝试获得更快的RAM速度之前，先将您可能拥有的任何额外预算花在更强大的组件上会更有意义。
希望本文已经回答了您可能对更快的RAM提出的任何问题。如果您仍然不确定，请随时与我联系，我很乐意为您提供建议。
Does Faster RAM Matter? – 2400MHz vs 3000MHz & Better
It seemѕ RAM is getting faster every day, but does fastеr RAM matter? Does it make sense to buy 3000MHz or is something like 2400MHz good enough?
Let’s take a look at what higher frequency RAM actually does for your system and whether it’s worth buying or not. Once you have finished reading, you will understand what faster RAM does, and whether it makes sense to purchase it or not.
An Introduction To RAM & RAM Speeds
Before we talk about RAM speeds, let’s look at what the RAM is used for.
RAM takes data from the hard drive, including data for programs and games, and it holds the data whilst you use those programs or games. This is because RAM memory is so much faster than your standard hard drive, or even an SSD. The data the RAM holds onto is then fed to the CPU.
With that reasoning, it would make sense that faster frequency RAM would mean better performance. But the end result isn’t so crystal clear. The trouble is, no matter how fast your RAM can send data to your CPU, there becomes a limit where your CPU simply can’t process all of that data fast enough.
Thankfully, the processor manufacturers have made the task of finding what speed is best suited for their CPU as easy as possible. All you have to do is look at the specifications for each chipset online.
For example, Intel suggests that their fastest supported RAM for the Intel i9-9900K is DDR4 2666MHz and AMD says their Ryzen 2600 CPUs support up to DDR4 2933MHZ. So why do RAM manufacturers sell faster RAM? It’s because with overclocking, those speeds can still be reached.
What does that mean? Well, if you go for the factory experience and don’t dabble in overclocking, going any higher than 2666MHz on Intel or 2933MHZ on Ryzen provides no benefit.
So if you are the kind of person that doesn’t touch the BIOS, you should opt for the MHz limits mentioned above. You can go higher if you find that the price is the same at higher speeds, but you won’t actually reach those speeds.
Overclocking To Get Faster RAM Speeds
Now, if you like to overclock or mess around in the BIOS, then going for faster RAM speeds may make some sense. By turning on XMP in the BIOS, you can potentially reach faster RAM speeds, but understand that this will only be possible if you have a supported motherboard.
The end result is that opting for faster RAM speeds after turning on XMP can help to improve frame rates in some games, whilst in others there’s almost no noticeable difference. It seems to depend from game to game, but many games did get better minimum frame rates.
Based on the results from Linus Tech Tips, we can see the difference isn’t incredible, but there’s certainly a difference. In some extreme cases, we are talking about 20 to 30 more minimum average frames. In some other cases, it’s as little as 5-10 more frames.
Benchmarks for non-game related tasks, like video editing, are hard to find, but it’s very likely it will be the same story: very marginal improvements in performance for faster RAM speeds.
Should You Buy Faster RAM?
With this information in mind, you may still be wondering whether you should buy faster RAM. Well, if you’re willing to overclock your RAM and don’t mind troubleshooting any potential issues that crop up, then it’s worth it.
But it’s only worth it if the price increase is marginal. For example, in some cases a 2x8GB 2666MHz kit on Amazon can cost exactly the same as a 2x8GB 3000MHz kit. Just $70 at the time of writing.
But I wouldn’t recommend it when RAM costs far more, for example a 2x8GB 4266MHz kit right now costs $269.00. That extra $200 would be better spent on an upgraded CPU, GPU, or even just more RAM.
Summary
In summary, so long as you are on 2666MHz or higher, it makes more sense to spend any extra budget you may have on more powerful components first before trying to get faster RAM speeds.
Hopefully this article has answered any questions you may have about faster RAM. If you still aren’t sure, feel free to reach out to me and I’ll be happy to give you advice.
