Is It Okay to Mix Different RAM Modules for My PC Upgrade?

It's important to know why you want to upgrade your RAM. Are you facing performance issues? If you're going to run demanding software like AutoCAD, you'll definitely want to ensure your RAM can keep up!

Consider what you value more: speed or capacity. If you mostly game or do general tasks, something like a 32 GB, 5600 MHz kit would be ideal. Mixing RAM is usually not the best route, especially if you're using an AMD system, where having all four slots filled can lead to instability.

You shouldn't hit any major issues mixing the RAM, but memory controller quirks might cause some headaches. I'd recommend selling your current sticks and getting a 2x64 GB kit if you need more capacity. At the end of the day, running memory closer to its limits can impact performance, especially with memory-intensive tasks like AutoCAD.

Mixing different RAM sticks can be risky. DDR5 often doesn't perform as well when using four modules, and while some people can run 6000 MT/s with four sticks, it's really hit or miss and often depends on the memory controller in your system. Unless you really need the capacity, it's often safer to sell your old RAM and invest in a larger kit instead.

It’s generally not recommended to mix RAM modules due to potential issues with timing and performance. DDR5 works best with two sticks, as using four can strain the memory controller and hinder speed. If you're focused on AutoCAD, I'd suggest going for a higher-capacity kit so you’re set for future projects. It's worth getting 64 GB if you can swing it, especially since price differences can be minor and it’ll save you headaches down the line.
