GDDR5 is a way more faster and complex than GDDR3.GDDR is not fit a DDR5 graphics card in a DDR4 motherboard same as DDR. Which is better a DDR5 or a GDDR5 Graphics Card? New motherboards tend to support either DDR4 fit a DDR5 graphics card in a DDR4 motherboard DDR3, but never both.here are few types of RAM like DDR1, DDR2, DDR3. If it says it supports DDR2, you can only use DDR2. Can a DDR2 graphics card fit on a motherboard DDR4? The only situation where the memory is shared is if you are using onboard built-in graphics. They don’t and shouldn’t interfere with each other. In fact, the graphics card won’t use the the motherboard DDR memory even if both are the same type. GPU VRAM works independently than motherboard RAM. It does’t matter as long it has no other compatibility issues.

Yes, you can use a DDR3 or DDR5 GPU on a DDR4 motherboard.
