I'm currently using 32GB of Kingston Fury DDR5 memory (two 16GB sticks running at 6000MTs). I recently bought two additional 8GB sticks from the same brand, but they run at a lower speed of 5600MTs. I wanted to upgrade my system to 48GB total RAM but I'm concerned about whether mixing these RAM sticks could negatively affect my performance. I've heard mixed things about compatibility and potential slowdowns. Is it safe to use all four sticks together?

If you're lucky, all sticks might run at 5600MTs, but that would be a downgrade from your current 6000MTs. There's a good chance the mixed speeds could cause your RAM to default to around 4800MTs, which could slow down your system significantly.

So, you're saying mixing the 5600 stick could drag everything down to 4800?
