The performance hiccups with mismatched RAM that you hear about generally come from much older systems (think Intel Core 2 Duo era), where with some motherboards if you mismatched the RAM sizes you'd be dropped all the way down into what's known as single-channel mode for all the RAM. Those performance issues even then were relatively minor, never exceeding single-digit percentages except in extremely RAM-bound tasks.

At the present day, you're just not going to see a huge performance hit running mismatched RAM, unless you're running tasks that are extremely RAM-bound (and even then only in edge cases). As for your question about clock speed, this is where getting into the specifics of what the RAM stick you will buy will support is good. Your RAM will always run at the slower of the two timings between the two RAM sticks, and of course the simplest way to ensure that you're getting the best out of your RAM is to run a matched pair. This isn't possible here, so what you can do is make sure that your 32GB stick has the same (or better) timings than the 8GB stick you are replacing.

In case anyone is interested, here's what CPU-Z reports for my 2022 G14:

  • DRAM Frequency: 2400 MHz (x2 = 4800 MHz)
  • FSB:DRAM: 1:24
  • CL: 40
  • tRCD: 39
  • tRP: 39
  • tRAS: 77
  • tRC: 116

Of these numbers, the CL, tRCD, tRP, and tRAS are usually reported as follows:

  • 40-39-39-77

For all of these numbers, lower is better. So you're looking for a 32GB RAM stick that has equivalent or lower numbers for all of them. If you go here, you'll notice that there's a 2022 G14 owner who asked whether this RAM was compatible, and the Corsair representative answers that CMSX32GX5M1A4800C40 is the compatible 32GB RAM stick. This RAM stick is 40-40-40-77 @ 4800 MHz, meaning that the entire system will run at these timings. This is only marginally slower, to the point where even on memory-sensitive benchmarks you won't see any difference.
