The Core i9-10900K from Intel is the best gaming processor at the moment. If you need the best gaming performance for the money and you don’t care about the price to performance ratio and better productivity performance found in Ryzen CPUs, the 10900K is the best choice you can get. But this beast of a gaming CPU needs quality memory to reach its limits. And which memory is the best choice for the 10900K?
It all depends on what you’re needs are. If you just want a stable memory that won’t limit your CPU and GPU performance any decent 3200MHz DDR4 memory should do it. If you plan on diving into overclock waters, you probably want expensive and fast memory with tight timings. Luckily, we’ve covered lots of use cases on this list. They range from the aforementioned relatively fast and stable but also affordable memory to ultra-expensive memory sticks that are cherry-picked and sold for ludicrous prices.
Now, before we start, a word or two about just how much RAM affects overall performance. We’ve covered this in our in-depth RAM guide for Intel and Ryzen CPUs so you should go and read that piece if you want to know all the details. But for those who just want the gist of it – Intel CPUs are indeed affected by the speed and timings of RAM sticks but not that much. If your budget is limited and you happen to own a 10900K-based system, or plan to build one, it’s better to invest in other parts.
A powerful AIO cooling system would bring bigger performance improvements than a super expensive RAM kit. The same can be said about a better GPU. But, if you already have top of the line components and your budget isn’t limited then yes, ultra-expensive RAM can give you both an uptick in performance and more overclocking headroom.
Next, while 16GB of memory is still enough for cozy gaming, if you own or plan to get the 10900K you probably also plan on getting 32GB of RAM. High-end gaming systems can see improvements from having 32GB of memory, especially when running games at 4K and high refresh rates. This is why this list mostly includes 32GB memory kits. But don’t worry, we’ve included a couple of quality 16GB kits for those on a limited budget. And also one 64GB kit for users who use their PC for work and gaming. Okay, now we can finally check out the best RAM for the Core i9-10900K.

Best RAM for Extreme Overclock
This memory kit is tested at 4800MHz, which means it should work without issues at 4800Mhz out of the box. All you have to do is turning on the XMP option. This is blazing fast speed and considering that primary timings are set at 19-23-23 @ 1.35V you’re looking at a fast memory for users who want to overclock their 10900K CPU.
Remember that the fastest memory kits around usually don’t include 32GB of memory so you probably won’t be able to get a 32GB kit that runs at 4000MHz or faster. If you want something like that, your best bet is to find a G.Skill 32GB memory kits that run at 3800MHz. Or something like that.
If you’re fine with 16GB of memory, this G.Skill memory kit should be great for overclockers. With the tested frequency of 4133MHz and primary timings set at 17-17-17-37, this is a perfect memory for overclockers to push it to its limits.
Best RAM for Most 10900K Users
This is a perfect choice for users who just want a relatively fast 32GB RAM kit they can simply install and forget about it. Your performance won’t suffer and while it’s possible to gain extra performance from faster kits, that uptick isn’t worth the price.
Unless you want to squeeze a couple of extra frames or have a serious OC rig that can drive the 10900K over 5GHz, this 3200MHz CL16 kit is a great choice. If you want something with RGB LEDs attached to it, check out our next pick down below.
Best RGB RAM for i9-10900K
If you want the slickest-looking RGB RAM on the market, check out the TridentZ kits from G.Skill. These sticks look amazing and they also feature excellent RGB lighting. They are compatible with all major RGB lighting software from a plethora of manufacturers so you should be fine with running this RAM on any motherboard.
We’ve linked the 32GB 3200MHz kit that offers excellent 14-14-14-34 timings at 1.35V. These are tight timings and with some overclock you can push this memory to 3600 or 3800Mhz. Then set timings at something like 16-16-16-32 and you should see a noticeable performance uptick. The best thing of all is that this memory isn’t that much more expensive than regular kits while offering excellent overclocking potential.
Best Bang for The Buck RAM
This Patriot 16GB memory kit is amazing. It’s relatively affordable, runs at 4400MHz, and it features excellent 19-19-19-39 timings@4400MHz. If you need extra performance from RAM but don’t have a lot of money to spend on memory, this is the memory kit to get.
The downside of this kit is that it only packs 16GB of memory. While this is enough for hassle-free gaming, it could be too little for users who game at 4K resolution. Nevertheless, when looking at the price to performance ratio, this memory kit is the winner.
Best Budget RAM for i9-10900K
Patriot and its Viper Steel series strike again. This time they took the award for the best budget RAM kit on the market. This 32GB kit features 16-18-18-36 primary timings and it runs at 3200MHz. Not, these clearly aren’t the tightest timings you can find on a 3200MHz memory kit but the affordable price justifies looser latencies.
Now, in real-life usage, looser timings shouldn’t bother the gaming performance of your CPU and GPU. Sure, you can get more performance out of a faster memory or the same speed memory but with tighter timings, but those kits cost lots more. For the money, this is an amazing pick and every budget-oriented 10900K owner should consider getting this memory kit.
Best 16GB RAM Kit for Most Users
If you need a 16GB memory kit that works great and is affordable, check out one of the two kits we recommend. They both offer excellent performance with fast speed and solid primary timings. For instance, the Viper Steel kit features primary timings of 16-18-18-36, which is pretty good for a budget memory kit.
The Corsair kit should offer similar timings and any difference shouldn’t affect performance in any noticeable way. And since its price is virtually the same as the Viper Steel memory, it doesn’t matter which one you pick at the end. Both are stable and fast 16GB memory kits that provide lots for the money.
Best 64GB RAM Kit for i9-10900K
If you need 64GB of RAM you probably use your PC for more than just gaming. This is why our first 64GB memory kit pick is a budget model from Kingston. It runs at 2666MHz, has okayish timings, and is perfect for 10900K-based systems used for video editing or rendering. This kit is cheap, stable, and provides enough performance for work and gaming tasks.
Sure, it won’t offer the same level of performance as faster kits that include less memory, but it has 64 gigabytes of it, unlike those other, faster kits. And if you want a faster version of this memory, you can pick anything from 2400MHz to 3466MHz. Just be ready to pay much more for a faster memory.
The next pick a bit faster but also a more expensive. This 64GB memory kit from Corsair is perfect for users who use their PC for gaming and work, but mostly gaming. 3200MHz speed is just right for playing demanding titles and is perfect for video editing and other work-related use cases.
