The Difference Between DDR3 and DDR4
Introduction
Every laptop, server, and computer needs memory to carry out the workflows efficiently. Server Memory, RAM is popular for its speed and allows better read times for your server.
What Is A Ram And How Does It Work?
RAM or random access memory is a short-term storage solution. It is a volatile memory, and it processes the data from HDD to the processor. It stores the actively running data so that it can be accessed quickly. There are two important server RAMs. They are DDR3 and DDR4.
What Is DDR3 And What Are Its Features?
DDR3 is a 3rd generation SDRAM and is an improved version of DDR2 RAM. It consumes 30% less power and is two times faster than the DDR2 RAM.
General Features
- Data transfer rate: 800 to 1600 MT/s
- Clock speed: 800 to 2133 MHz
- 1.5 or 1.35v operating voltage
- Performs auto-refresh and self-refresh for refreshing content
Advantages Of DDR3 RAM
Significant advantages of DDR3 include,
- Better in all aspects compared to DDR2.
- High bandwidth capacity.
- Offers increased performance at low voltage.
- Provides cooler operating temperatures.
- Offers less CAS latency.
- Cheaper than DDR4 RAM.
What Is DDR4 And What Are Its Features?
This is the latest version of DDR RAM. It consumes very little power and is very progressive compared to the DDR3 memory. As a result, it is widely used in the next generation of computing.
General Features
- Data transfer rate: 2133 to 3200 MT/s
- clock speed: minimum 2133 MHz and no defined maximum limit
- 1.2v operating voltage
- Performs self-refresh for refreshing content
Advantages Of DDR4 RAM
Significant advantages of DDR4 include,
- Better speed and bandwidth compared to DDR3.
- They are highly flexible and expandable.
- Can effortlessly store more signal layers.
- Easily handles powerful processors.
- Has a higher chip density than DDR3.
Difference Between DDR3 And DDR4
- Maximum Memory Limit
The maximum memory limit of DDR3 16GB, whereas there is no defined maximum memory limit or capability for DDR4. - Speed
DDR4 is slightly faster than DDR3 memory. In contrast, the speed of DDR3 memory lies between the speeds of DDR2 and DDR4. - Latency
DDR3 has a great benefit when it comes to latency. It has low latency (9 or 10 CAS) compared to the DDR4 RAM (15 CAS). - Use Cases
DDR3 is used in earlier computer systems, whereas DDR4 is being used in the latest computer systems. - Power Consumption
DDR3 consumes less power than the DDR2 memory, but it expends more power than the DDR4 memory. - Pin Interface
DDR3 memory has a 240-pin interface, whereas DDR4 memory has a 288-pin interface.
Which One Is The Best Option?
To declare one as the best RAM is a difficult decision to take, but it can be done depending on the user requirements. If you can’t risk the latency and need a cheaper solution, then DDR3 is the choice for you. Otherwise, you can go for DDR4.
How To Know Which Type Does My System Support?
The middle of the DDR4 module has some longer pins and looks like a curved ‘V’ shape. You can cross-check this with your motherboard documentation to find out if it can fit in your system.
Can I Install DDR4 RAM In The DDR3 Slot?
No, you cannot install DDR4 RAM in the DDR3 slot as DDR4 has no backward compatibility.
Takeaway
RAM has a great impact on your system’s speed and performance. While DDR4 offers many advantages compared to DDR3, it is not entirely flawless. But no matter whichever memory module you choose, they can meet your expectations without any doubt.
