Best memory for Intel Core i9 14900KS

Intel has once again blessed the gaming community with a new top-tier PC gaming CPU. It’s basically an upgraded version of the i9 14900K, with a higher turbo boost speed. Of course, if you’re keen on upgrading to the 14900KS, then you’ll need to make sure that your memory is up to the task. So, let’s take a look at the best memory for the Intel Core i9 14900KS.

It's worth remembering that every CPU has a certain set of preferences when it comes to memory. A lot of random RAM might well work, but to really get the most out of a CPU this powerful and avoid any potential bottlenecks you should aim to get RAM that falls within the following specs. (All the options we’re selecting will work with this new CPU, so no worries there.)

Ok, given that the i9-14900KS can work with both the newest DDR5, and the rapidly depreciating, yet still powerful DDR4, you have many options to choose from.

The primary difference between DDR4 and DDR5 is the maximum memory bandwidth and maximum memory density on offer.

Bandwidth is largely defined by the speed of the RAM. The official specs for DDR4 RAM top out at 3,200MT/s, whereas DDR5 is already rated up to 8,000MT/s. Given that DDR5 is still a relatively new standard, it may get even faster than that in the future.

Density, by comparison refers to the maximum capacity of a single module, or stick. DDR4 RAM has a theoretical 64GB per module limit, although in reality you'll generally see a maximum of 32GB per stick. DDR5, on the other hand, is going to hit a maximum of 128GB: 2x the density of DDR4. We have a full DDR4 vs DDR5 article if you want to get super nerdy about it, but for now, back to the best memory for the Intel Core i9-14900K.

Just before we give you our selections, it’s worth mentioning that for most people, specifically gamers, there exists a point where diminishing returns plays a role and there isn't much point going for massive memory capacities.

Unless your PC is used for 3D rendering, high resolution video rendering, or something similar, you’ll want to get something between 32GB and 64GB. This is the sweet spot that PC games actually have a chance at utilizing.

64GB of RAM is worth getting if you’re a multi-monitor, multi-tasking maestro. The additional headroom vs 32GB will make switching between different programs and open windows a touch smoother. Though, the pure gamers out there will be totally fine with 32GB. Ok, educational whistlestop and capacity disclaimers are all done. Here’s the best RAM for i9-14900KS.

If you’re unconcerned with trying to max out the price-to-performance ratio of your build, and just want to go wild, this is the kit for you. It’s costly, but it will allow the 14900KS to fully stretch its legs, and you won’t run into any slowdown when multitasking for a long time.

It’s CORSAIR’s latest and greatest memory, available in many configurations, white and black colorways, and the top bars are removeable so you can customize the aesthetic to an extent, which is always nice.

It’s worth noting that the DOMINATOR TITANIUM memory is fairly statuesque at 57mm. So, even though it’s the best of the best right now, those with air coolers should double check the compatibility. (Our A115 air cooler is totally compatible, thanks to the adjustable fan mounts, by the way.)

If you want almost all the performance of DOMINATOR TITANIUM, while saving some money, the VENGEANCE lineup is the correct solution right now. It comes in almost all the configurations that DOMINATOR TITANIUM does, and the only noticeable differences are the lack of RGB lighting and the reduced height. Both of which can be benefits depending on your priorities. A happy coincidence, or maybe we intended it that way? We’ll never tell.

We’re recommending 32GB of the VENGEANCE RAM, too, as briefly mentioned above, those who prioritize pure gaming performance will see basically no improvement going from 32GB to 64GB. So, going with this kit allows you to allocate some budget elsewhere, perhaps to afford the i9-14900KS you’re trying to find RAM for right now.

For those who have the budget and the need for much more memory, the 192GB kit of VENGEANCE RGB DDR5 is a strong choice. This is only necessary for properly heavy-duty production use cases. Think fluid simulations, video rendering, 3D asset creation, etc.

The programs that support this sort of work will gobble up all the resources they can possibly get, making them the sole realistic application for this volume of RAM.

Here we find the best value-for-money proposition for those who are not fussed about making the jump to DDR5 just yet, the VENGEANCE RGB PRO SL 32GB kit. While the maximum density and speed are way lower than what DDR5 can provide, you'll still hit some sweet framerates with decent DDR4. Here's a full breakdown of the difference DDR5 makes over DDR4 in some of the latest games.

This means that DDR4 will still be able to push these games to stratospheric FPS and allow for immersive fidelity, while being a bit easier on the pocket too. One of those nice conclusions that vindicates the stingy consumer.
