Frequently Asked Questions (FAQs) By Most Users

How fast is DDR3 RAM?

Since 2007, DDR3 RAM has been known for its high performance with less power consumption in comparison to DDR and DDR2 generation. So, let’s see the speed of various variants of DDR3:

Popular NameIndustry NameData Transfer/Second (in millions)Module Peak Bandwidth

DDR3-1866PC3-14900186614900 MB/sec.

Is DDR3 good in 2020?

The short and simple answer to this question is Yes, the DDR3 RAM is still good. If you compare DDR3 vs DDR4 benchmark, then you will notice that DDR4 RAM is faster. But, when you yourself compare the performance, you will only observe a little bit of difference between the two if you run them at latency frequency according to the appropriate speed. 

The only major difference between the two and reason why DDR3 will not be good is that certain newer motherboards and Chip architectures do not support DDR3 RAM. They are compatible with DDR4 RAM only.

Which Intel CPU support DDR3?

In our list of best DDR3 CPUs discussed above, we have mentioned some of the top-notch and best Intel DDR3 CPUs, including Intel Core i7-4790K, i7-5775C i7-3770, and many others.

Is 16GB DDR3 RAM good for gaming?

The answer is Yes, 16GB DDR3 RAM is good enough for gaming for the current scenario. For most of the games, you will never run out of RAM if you have a 16GB chip. The only catch is, there shouldn’t be any heavy memory-consuming application running in the background. As far as gaming goes, 16GB memory is plenty, but if you still want to push the frame rates, you can invest in a good graphics card.

Is DDR3 RAM compatible with the DDR4 motherboard?

Comparing DDR3 vs DDR4 CPUs and RAMs, we can conclude that DDR3 RAM is incompatible with the DDR4 motherboard. The main issue is that the slot of DDR4 is a bit wider than the DDR3 slot, and the notches of both the slots do not align at all. So, it becomes impossible to fit DDR3 in the DDR4 slot and vice versa. 

Furthermore, there is a difference in the power consumption of both the RAMs. DDR3 requires 1.5 V and 1.35 V for normal operations and power save mode, respectively. On the other hand, DDR4 requires only 1.2 V for normal operations. So, if somehow you fit DDR3 in the DDR4 slot, the motherboard will not be able to supply the required voltage.


We hope that if you were confused about which DDR3 CPU will be best suited for you, this article might have helped you in making an informed decision. An efficient DDR3 CPU can help you get the most out of your RAM, whether it be faster data accessing, high-definition gaming, quality video streaming, or multitasking. 

In our view, Intel CORE i7-4790K CPU is the Best DDR3 CPU at present. It has got all the features that an efficient DDR3 CPU must possess. This 4th generation Intel-Core i7 quad-core processor named Devil’s Canyon offers an outstanding clock speed of 4GHz, which can be boosted up to 4.4GHz using the Intel Turbo Boost 2.0 technology. In addition to this, the processor is unlocked for convenient overclocking and is also hyper-threading enabled.
