Insufficient PC RAM can negatively impact productivity. Understanding the differences between DDR3 and DDR4 RAM is crucial for those in the market, as they can impact their needs and preferences.
What is RAM?
RAM, or Random Access Memory, is a computer memory that allows for read and write operations in any order, typically used by the CPU to store frequently accessed data.
What is DDR3?
DDR3 uses auto-refresh and self-refresh for content refresh, reducing power consumption compared to DDR2. Its clock speed ranges from 800 MHz to 2133 MHz, with a peak at 2133 MHz.
What is DDR4?
In DDR4, it only performs self-refresh to refresh its content which is why it consumes less power. DDR4’s minimum clock speed is 2133 MHz, and no maximum clock speed is specified.
Now that the RAM is explained, it is time to understand the differences between ddr3 vs ddr4 server:-
1. The two do not work in conjunction
DDR3 RAM uses a 240-pin connector, while DDR4 RAM uses a 288-pin connector, indicating a physical difference in pin layout between the two modules.
Why are the two different?
The motherboard and CPU compatible with DDR3 RAM may not work with DDR4 RAM, and vice versa. The connector differences ensure proper installation. Not all RAM functions with all processors, even when fitting into a motherboard. Research and ensure compatibility for all PC parts.
2. RAM DDR4 seems quicker on the paper
RAM data transfer rate is measured in MT/s (million transfers per second) or GT/s (billion transfers per second), with higher rates indicating more bandwidth. DDR4 RAM can transfer data between 2133MT/s and 4266MT/s, while DDR3 RAM can only transfer between 800MT/s and 2133MT/s.
3. DDR4 RAM uses less voltage and costs more
RAM DDR3 has a voltage level of 1.5V, while DDR3L uses 1.35V and 1.5V. DDR4 uses 1.2V and initially had a significant price gap. DDR4 memory modules support deep power-cut-off mode, reducing power consumption by 40-50%, and allowing the host system to enter standby.
DDR4 RAM offers reduced power consumption, lower heat generation, and longer battery life, allowing systems to run 24/7 with higher memory and onboard fans and outboard ventilation for comfort.
So what RAM do you choose?
The choice between DDR3 or DDR4 RAM depends on the current hardware and the hardware plans for the future.

Frequently Asked Questions
Q1. What are the types of RAM?
- SRAM
- DRAM
- FPM DRAM
- EDO DRAM
- SDRAM
Q2. What is Random Access Memory used for?
RAM is a crucial computer component that stores and manages application data, ensuring easy access and control of the device’s output.
Q3. Can I upgrade DDR3 with DDR4?
DDR4 RAM is not compatible with DDR3 motherboards, and the notch has been moved to prevent incorrect memory insertion, preventing the switch to DDR-4.
