The short answer is yes you can use DDR3 on a DDR4 motherboard. This article will discuss the differences between the two types of RAM and what to look for while upgrading your PC. DDR3 vs DDR4: The first thing to know about these two types of memory, is that they are not compatible with each other. If you buy a new computer or video card, it’s important to make sure it supports DDR4 before buying any RAM upgrades.
Most computers made in the past five years support both DDR3 and 4 so this shouldn’t be an issue for most people though. There are also some motherboards which only support one type of memory (DDR3 or 4) but these are typically older models. DDR Memory Speed: The second thing to note is that the only difference between DDR and DDR memory types, is their speed.
The D in both acronyms stands for double data rate – meaning it’s twice as fast than traditional DRAM modules from earlier days of computer technology. For most people this won’t matter much either but if you’re into hardcore gaming then this might be an important factor for your next PC upgrade purchase decision.
Conclusion: As long as your motherboard supports upgrading with a newer type of RAM (either DDR or DDR) there are no real issues when trying to upgrade using something like a DDR -ram module on a new pc build which uses one of the other variants.
