Best RAM for Core i9-11900K

RAM will help you find the fastest memory kit for your system. Memory is one of the essential pieces of hardware in any CPU system. The right or wrong memory kit can significantly impact your overall system performance for gaming, productivity, and (if you don’t have enough) general sluggishness.

Indeed, it is true that RAM speed builds a massive difference in the potential performance of Rocket Lake CPUs. There is quite a bit of FPS at stake when playing games when you have limited CPU RAM.

Make sure XMP is enabled if you specify a faster memory kit. However, the H570 and B560 motherboards allow overclocking RAM for i9-11900k and higher RAM speeds. You must balance performance against cost so you can get the most out of your 11900K, whether you want an XMP profile set up and forgotten or have the time and skill to take full advantage of the overclockable RAM on this platform. If you’re pushing the limits of performance, you can gain even more by selecting fast RAM and manually adjusting the timings for minimal latencies. 

In this guide, we’ll go over our recommendations for the best RAM for i9-11900K.

How does RAM work?

RAM is intended for the short-term storage of data required by the PC for regular operation. However, unlike hard drives and SSDs, where data is stored indefinitely, RAM is cleared every time the system is rebooted. RAM only works when powered, distinguishing it from non-volatile storage devices such as hard drives and SSDs. Programs are loaded into RAM only for the duration of use, but at the same time, they are stored on drives permanently (until they are deleted).

What are the Important characteristics of RAM for i9-11900k?

Computers need quick access to temporary data to run programs and perform tasks. For example, modern computer games need to load graphic resources quickly. Games use RAM to read and write data because it is much faster than non-volatile storage devices.

Two factors included judging the characteristics of the RAM for i9-11900k.

  • Speed: Memory speed is measured in millions of transfer operations per second (MT / s), often confused with megahertz (MHz), although memory speed and clock speed are different. Higher memory speeds mean faster responsiveness to read and write requests and, therefore, better performance.
  • Capacity: It can be measured in gigabytes (GB). The chance to store more data applications when you have high storage capacity. With more RAM capacity, more applications can run simultaneously, and games can store more temporary data in it.

What kind of RAM is compatible with your motherboard?

Before you start thinking about RAM capacity and frequency, you need to make sure the RAM is compatible with your motherboard and your processor. Memory modules of the wrong type will not work, and if they do not meet the specifications, the memory performance will be lower than expected.

  • Module type

RAM is produced in the form of modules that are installed in connectors on the system board. RAM incompatible with your system will not fit or work properly. Modern motherboards support DDR4 memory modules. DDR4 memory should not be confused with DDR3 memory, which is the previous generation of SDRAM memory. These two types of memory modules are not interchangeable, and you cannot replace (for example) 8GB DDR3 memory with 16GB DDR4 memory.

  • DDR4 or SDRAM

Computers use random access memory (SDRAM). Synchronous DRAM is synchronized with the processor frequency. SDRAM has been continuously improved and now offers lower power consumption, faster data transfer rates, and more stable data transfers.

Modern computers use DDR4 or SDRAM memory as a standard. DDR4 DDR technology is the fourth generation and has been replaced with SDRAM technology. DDR4 memory has increased data transfer rates, increased capacity, and lower operating voltage than previous-generation memory.

What speed of RAM do I need?

Find the right balance between capacity and speed. Chances are, 32GB of slow RAM won’t be ideal, as is 4GB of fast RAM. DDR4 memory speeds start at 1600MHz, but this is not fast by today’s standards. For example, the Intel Core i9-10900 processor supports 2933MHz memory in its base configuration.

In games, higher frequency RAM is beneficial. While the effect is not as noticeable as replacing the processor or graphics card, faster memory can also improve game performance and frame rates.

The performance improvement will vary from game to game; some games will run much faster, while others will be subtle. To assess the need for an update, you should look at the benchmark results with average frame rates.

In addition to raising the frame rate, faster memory can provide frame rate stability and faster frame loading. These figures will be presented in tests as low values ​​of 1% and 0.1% (average slowest indicator for 1% and 0.1% of recorded frames).

In addition to improving frame rates, fast RAM can improve game performance in other areas, including shorter loading times.

Tips for having the RAM for i9-11900k?

It certainly helps, to choose a PC with a good amount of features. It doesn’t matter which brand is perfect; everything can be pushed or improved to accommodate more skills. This includes your system RAM for i9-11900k, which creates a massive difference in running programs.

It is normal to have doubts when deciding the exact model or speed that your system needs or which one to choose RAM, for i9-11900k. Indeed, the timing of clock speed (MHz) and RGB count for something. However, there is more to choose from than the best when looking for RAM.

Here are some tips to help you:

Heat diffusers and lights

Heat spreaders are part of most RAM kits. RGB LEDs are exceptionally stylish. Both are basically for display. It is a fact that most of the memory does not run fast at the time of manual overclocking.

Somehow, they do not require aluminum or metal heat spreaders. Bare sticks are a great option; if there’s enough airflow to get through the case and over the memory. Also, the flashing lights don’t affect the performance of the RAM for i9-11900k. If you are looking for something flashy that comes with all the modern features, you can choose any RAM for the Intel core i9-9900k

The clock speeds are excellent, but your system should support them

Buying RAM with clock speeds that are not compatible with your system will hurt your pockets. Memory speed is limited on some CPUs, especially on lower-end Intel models. You should check what your system will allow and buy accordingly. There is no use buying a RAM rated at 3200 MHz when all your system can support is 2666 MHz. You will probably lack the high speeds to run your favorite programs. Always check the supported specs before opting for a new RAM.

16GB – perfect standard size

At least, that is the case when the prices associated with said memory are considered. Mainstream programs or different games can run on 8GB, but other running programs could consume that. What you want, especially if you run heavy stuff, is more space. As such, 16GB or 32GB memories are worth a try.

Some programs and games do not need significant RAM speeds

This is true even if you have identified the memory you want to pay. There are a lot of software programs that don’t benefit from faster and shorter memory.

If you are looking to recover some memory, you must research the games or programs you use the most. This way, you can use slower RAM in conjunction with a system that carries a dedicated graphics card.

Integrated graphics result in improved speeds

Playing without a dedicated graphics card is fine. You’ll see improved frame rates with faster support memory, but if it takes longer to work on the components to support that speed, it’s essential to get a dedicated card. In this way, there is better gaming performance in all aspects.
