Considering this, can I put ddr4 RAM in a ddr3 slot?
No, it is not electrically nor electronically compatible. DDR4, for example, runs at 1.2V (volts) while DDR3 runs at 1.5V (or 1.35V for DDR3L). A DDR3 RAM slot will provide that voltage. That's basically to protect you from trying to jam a DDR4 RAM into a DDR3 RAM slot and damage something.
Additionally, can you mix ddr4 and ddr5 RAM? But they will also work. So, for your answer, Yes. A DDR4 motherboard is so modern that it will surely support any DDR5 gpu. DDR4 denotes the speed of ram and DDR5 is for Vram (graphics card memory). The slots are completely separate.
Likewise, people ask, can I put 1600mhz ram in a 1333mhz slot?
RAM does not run at the speed it is sold at, it is sold at the maximum speed it is guaranteed to work at. 1600mhz RAM will work at 1600mhz, or any speed less than that. RAM speed is set by your motherboard and processor combination. In short, yes 1600mhz ram will work at 1333mhz just fine.
Can I use ddr5 graphics card with a ddr2 or ddr3 RAM motherboard?
Yes you can. The DDR3, DDR5 of a graphics card is the VRAM type/version it has. The DDR2 of the motherboard is the main system memory, i.e. RAM, type, not the graphics card memory type. The only thing you need to check is whether or not your motherboard has a PCI-E slot.
