With the passage of technology, such as 3rd gen RAM and 4th gen RAM different types of memory have emerged that improved the previous generation, DDR, DDR2, DDR3 and the recent DDR4. After the passage of the old SDRAM memories that accompanied us throughout the 1990s, the era of DDR memories began in 2000 and continues to do so today.
3rd gen RAM and 4th gen RAM: Differences between different types of DDR4 memory
Today we are going to focus on the most recent DDR4 memories and try to explain the differences between their different types. Let’s get started.
Are you looking for ram maintenance or ram repair near me, then you should know that it is very unlikely that you will get your damaged RAM repaired, because RAM consists of integrated circuits and when one is burned then there is now way to get it repair. It is always best idea to get a new one from the store located near you.
DDR4
This is the fourth generation of DDR RAM that was released in mid-2014 along with compatible motherboards and chipsets. During the first quarter of 2015, the mobile versions were also available.
DDR4 was a major breakthrough in data transfer speeds over DDR3 with lower power consumption. Among some of the improvements introduced we could talk about a higher bandwidth, the reduction of the manufacturing process to 20nm and the possibility of creating modules of 16 and 32GB.
Currently, units of this memory are available with a speed from 1600MHz to 4266MHz, the higher the performance, the higher the performance. DDR4 memories usually work with voltages between 1.2 and 1.35 v and have a peculiarity, almost all commercial models use a heatsink to keep them cool as they usually raise their temperatures at full load.
The advantages over DDR3 are obvious, but also somewhat more expensive.
DDR4L
This type of memory is similar in features to a normal’ DDR4, only designed specifically for servers and laptops. The key to DDR4L memory is that it requires less power to operate, with 1.2-volt volts that allow you to save 10% in power consumption. Different models are available with speeds between 2133MHZ – 2400MHz and can be used in conjunction with normal’ DDR4 memory.
DDR4U
This memory is also designed for servers with frequencies between 2133 / 2400MHz, with modules from 2GB to 16GB. This report is similar to the two we mentioned earlier, only giving priority to energy efficiency. It’s also the rarest type of memory you’ll find today, and most people rely on DDR4L as their low-power memory.
LPDDR4
LPDDR4 type memories were first used in 2015 and are specially designed for mobile devices. As you can imagine, this type of memory consumes very little power to preserve as much as possible the autonomy of mobile devices and tablets but sacrificing much of the speed that has a normal DDR4 memory.
LPDDR4 memories work with frequencies of 1600MHz and minimum voltages of 1.1 volts. Over time, manufacturers launched LPDDR4E, a new advanced model that improved frequencies to 2133MHz.
GDDR4
GDDR4 memory has not been used for a long, long time. Many years ago they were used specifically for graphics cards. These memories worked with 1.5 volts and promised to improve speed and power consumption but their period was very short and ended up being quickly replaced by the GDDR5 memories and the new GDDR5X.
One of the few graphics cards that ever used GDDR4 memories was the Radeon X1950 XTX or the Radeon 3870, some of the top of the range graphics cards back in 2006 – 2007. Who doesn’t remember these graphics cards?
Final conclusions
These are the differences between the different types of DDR4 memory. I hope you have solved your doubts and I will see you at the next one.
