I'm building a PC with a Ryzen 5 7500F and a Radeon RX 9060 XT 16GB. I'm deciding between a 16GB DDR5-5200 CL36 kit and a 16GB DDR5-5600 CL36 kit. The faster option would cost enough that I'd have to downgrade my SSD or buy used memory. I may also be able to find a used DDR5-6000 CL36 kit. The RAM has an EXPO profile, but the 16GB option I found is a single stick rather than a 2x8GB kit. How much difference will the memory speed make, and should I prioritize faster RAM, dual-channel memory, or a different CPU instead?

For Ryzen 7000, DDR5-6000 is often considered a good target, but it isn’t mandatory. A reasonably priced 2x16GB DDR5-6000 EXPO kit would be ideal, while 5200 or 5600 is still usable if that lets you keep the better SSD. Used memory can be fine as long as it is tested and has matching modules.
A 7500X3D or 7600X3D could improve gaming performance more than moving from 5200 to 5600, because the extra cache matters more than that small memory-speed increase. However, only consider changing CPUs if the price difference is reasonable and the faster chip is actually available in your area.
The difference between DDR5-5200 and 5600 usually isn’t worth more than about $20. In many games it may only amount to a few frames per second, and you can potentially tune the 5200 kit later if the memory chips allow it. Just make sure the kit is stable before pushing higher speeds.
The bigger concern is that this is a single stick. One 16GB module will run in single-channel mode, which can hurt performance more noticeably than the difference between 5200 and 5600. I’d prioritize a matched 2x8GB kit at minimum, or preferably 2x16GB if your budget allows.
That makes sense. I can also potentially find a used DDR5-6000 kit, so I’ll compare that against buying a proper two-stick kit instead of focusing only on 5200 versus 5600.
