A faster PC
I was finally able to exploit the potential of my i9-9900KF by replacing 2x8GB DDR4 3000MHz CL16 (16GB) with this 4x8GB DDR4 3600MHz CL16 (32GB) RAM kit. The difference is glaring in terms of stats, with only a 20% increase in frequency.
The Low Profile is still good, but be sure to check that your ventirad doesn't deprive you of 1 RAM slot before choosing the 4-slot solution.
Don't forget to activate the XMP profile in the BIOS once they've been installed ;)
