Best RAM for i9 12900K 2023

The i9-12900K is the newest Intel CPU to join the market. It has an incredible 12 cores and 24 threads, with speeds over 5 GHz. This processor uses the second generation of Coffee Lake chips, so it is very fast – but also very hot. This processor comes with a huge heatsink that can run at 90C without problems (at 100% load), but even if you only use 50% of its power you will need to dissipate more than 20W through this heatsink. This is why this processor needs very good cooling and the Best RAM for i9 12900K you can get. The purpose of this guide is to make a list and review of the Best Overall Ram available right now, with some basic information about what you should look at when choosing memory, and why it’s important. This guide will cover RAM that is compatible with the latest Coffee Lake processors but also post second-generation chips. The system requirements of the 12900K are really high, so you will need to invest in high-quality memory.

To give you an idea of ​​the Best RAM for 12900K, the worst memory is DDR4 2133MHz. This is because this frequency was used by Intel’s sixth-generation processors (Intel Skylake). With these old CPUs, it made sense to use lower frequencies since they did not consume much power and the performance gains were moderate. The i9-12900k processor can be clocked at frequencies above 5 GHz, so it will not use DDR4 2133MHz memory. Most consumers of this i9-12900K processor will want to maximize performance (overclock it) and get the most out of their components. This means that you should focus on the highest frequency possible. The standard is DDR4 3200 MHz, but if you can afford it go for DDR4 3600 or even 4000 MHz – because they offer twice or four times more bandwidth than traditional memory.

However, there are some limits when you overclock your system with high-frequency RAM sticks. Every motherboard has a physical limit on how much it can handle in terms of memory frequency. If your motherboard cannot manage to maintain stability at this new frequency then it might end in a freeze or in an instant reboot. This is why you should invest in memory sorted by overclocking potential. The best DDR4 3600 MHz and 4000MHz will not offer the same overclock capabilities as the worst DDR4 3000Mhz, so get this into account when choosing your RAM because it can save you time, money, and frustration.

Quick Buying Tips!

When choosing your memory, you will need to consider the following factors:

Clock Frequency: This is simple – you want the frequencies at their maximums. However, this information can be difficult to find because manufacturers of large online shops do not usually provide these values. This means that you will have to look into reviews and testing sessions of hardware journalists in order to get a more precise idea about what frequency your memory can reach before being unstable.

Type of memory module: Currently, there are four types of RAM sticks with different technologies. They are called DDR4, DDR3L, DDR3, and DDR2. It is important to know which type of memory your motherboard uses because some CPUs or motherboards can only use certain types. For instance, the Intel 1151 (and Coffee Lake) support DDR4 and DDR3L – but not DDR3 or DDR2. There’s more information on the subject here if you’re interested.

Capacity: 32GB of RAM is currently considered optimal for gamers who are serious about having a smooth experience when playing games in ultra settings (like PUBG). Hardcore enthusiasts might opt for 64GB of RAM. This comes with a price premium, so keep it in mind when investing in high-frequency memory modules.

Type of memory chip: This is also important to check if you are planning to use your memory overclocked. Some modules only have a certain number of pins, so it can be tough finding compatible modules – check this list for more information.

Type of chipset JEDEC or XMP profiles: The first one will require some manual configuration before installation or inside the BIOS, but you might not want to do it by yourself. There are too many steps involved and chances are you will mess up at least one – so choose the second alternative if possible.

Lastly, it’s important to consider that all of these parameters increase exponentially with each generation of processors and chipsets – which means that there is no single best DDR4 3200Mhz RAM stick, even if it might be the case right now. You will need to invest time in research and you should expect to follow up on misinformation online before getting the best high-frequency memory modules for your system.

GeILGeIL Polaris RGB Sync DDR5-5200 Polaris RGB Sync DDR5-5200

GeIL Polaris RGB Sync DDR5-5200

Best Mid Range RAM for i9 12900K


 Stands out in the crowd

 Smooths performance for gaming and other tasks

 DDR5 2,000Mhz potential (with compatible motherboards)

 Attractive RGB lighting system

 Easy to install



GeIL’s newest series of memory modules is the Polaris RGB Sync DDR5-5200. These modules are compatible with both ASUS and Gigabyte motherboards that support Aura Sync technology . The modules themselves feature a black PCB and aluminum heat spreaders to help dissipate heat, allowing greater overclocking potential. They also have an LED lit logo on top which can be controlled through Aura software. The GeIL Polaris RGB Sync DDR5-5200 comes in 16GB (2x8GB) kits at speeds of either 2133Mhz or 2400Mhz depending on your motherboard capabilities. The frequency of the modules can be boosted up to DDR5 2,000Mhz if your motherboard is capable. This memory is currently available for about $100 and can be found in most stores.

When it comes to gaming, the more your computer has at its disposal, the smoother and faster it will run. Games push hardware to its limit, requiring a lot of precious resources such as RAM (random access memory). 8GB of system RAM is still enough for many AAA titles today but as time goes on we’re seeing games require more and more of this expensive resource. With that said, if you want to ensure that your processor isn’t bogged down by unnecessary tasks you should consider getting an adequate amount of ram. As an example, let’s say that you’re running a game in which the minimum requirements are 4GB of ram. If your system only has 8GB then even if Windows is using 2 or 3 GB the rest will be left unused by applications and when gaming kicks in, it’ll significantly reduce performance. This can happen when running memory intensive applications such as Photoshop too.

When it comes to performance DDR4 memory is currently the best option. Older generation DDR3 can be found much cheaper but it’s not worth purchasing at this time due to its lower bandwidth and additional latency. That being said, newer generation Intel CPUs are only compatible with the DDR4 format. The good news is that current motherboards allow users to easily upgrade their ram so you won’t have to worry about buying a new one if yours doesn’t support DDR4.


The GeIL Polaris RGB Sync DDR5-5200 is an excellent choice for gamers looking to get the most out of their computer. Not only can it handle any game you throw at it, but its unique design will stand out in your rig and turn heads on your next LAN party or gaming tournament. If you want to take advantage of this powerful memory’s features, don’t wait!

If you have a lot of money to spend, then there are plenty of high-quality options with generous amounts of storage space that will work well in your system. But if you want something more affordable but still good quality, we recommend one or two sticks with 8GBs each (or 16GB total) at speeds up to 3200MHz or 3600MHz. If you’re wondering how much faster or more stable your computer will be with the best RAM for i9 12900K, it’s difficult to say exactly. If you’re buying for maximum performance than any of our picks would likely work well because the only limiting factor is your motherboard and CPU (and not really their limits). You might see up to a 5% or so improvement in benchmark scores, but this would depend on what types of tasks you do most often. But if you want increased stability than choosing an option that can maintain top speeds over long periods of time is important.
