How to Choose the Best RAM for i9 9900K (Buying Guide)

First, let’s start with the basics. You already probably know RAM is the random-access memory or the temporary memory of a computer. But what does it do?

RAMs give your CPUs the efficiency you need. Without good RAM, your computer will run slowly, and you won’t be able to use multiple features of the computer at once without it crashing. So, having good quality RAM is essential.

However, if you only use your computer for a desk job, a lower quality RAM with 4-8GBs of storage could work, and at the end of the day, it depends on what you use your computer for.

You must buy RAM that is compatible with your CPU. Now that technology is advancing faster than ever, newer and newer models of CPUs are coming up on the market. And, because of this, older models of RAMs are not compatible with them.

Besides this, there are multiple other reasons why a RAM might not be compatible with a CPU. For instance, its brand might not be compatible with the brand of the CPU, or the RAM’s speed could be too high, or the size and shape of the RAM might not fit into the RAM slot.

If you have a RAM that is not compatible with your CPU, do not use it as it could destroy your motherboard physically and or electronically!


To get the best performance out of your CPUs, you must purchase a good quality RAM. This is also true for CPUs like the i9 9900K; although they are excellent, they won’t give you the best performance without appropriate RAM.

However, buying reliable and compatible RAM can often cost a fortune. So, the top contender of RAM for i9 9900K CPU is the Corsair Vengeance RGB Pro 32GB, but other RAMs can perform equally well. So, if you have a i9 9900K CPU, do not hesitate to give these RAMs a try!
