I possess one 16GB DDR5 RAM with 5600MHz speed. I'm curious if switching to a different brand in dual-channel, such as Kingston, would work since they share the same frequency and CL. It might impact performance or cause issues like failure to boot if not compatible.
It’s unlikely you’ll get perfect results with XMP/EXPO unless your RAM speed is high enough for DDR5. The best approach is to align key specs: around 5600 MHz, using the three main timing settings (like 36-38-38) where 36 is the CAS latency or CL36. Matching the chip type matters too—Samsung B-die works well with certain controllers. Purchasing two sticks ensures compatibility from the factory. If one stick doesn’t match another brand (e.g., Samsung vs Nanya), it might still function, but mismatches reduce success chances. Ultimately, aim for the highest shared JADEC frequency and timing if the motherboard can’t find a fit. If not, the RAM should still run, though performance may suffer. For more details, see Anantech’s insights on DDR5 timings.
RAM is RAM, it should all just function properly or there’s an issue. Brand names and details don’t matter, you can combine them as you like, and it should work in theory. Regarding speed, the whole setup operates at the same standards, which you or your motherboard choose. So if you get a less powerful module, it may restrict the performance of the other, or you might have to push beyond the listed limits, which could lead to problems with stability. That’s why we recommend getting matching modules; otherwise, it’s likely a waste of money, whether now or from a previous buy, depending on the circumstances. But that covers the basics—it’s not strictly required.
