DDR3 vs DDR4

You you can install DDR3 into that slot. DDR3l is means that its normal DDR3 but requires less voltage to opperate. The only downside to non DDR3L is power draw which. Sep 25, 2014  No, you cannot use DDR3L ram in a DDR3 slot.the L designator is for low-voltage ram and will not work with the higher voltage of the DDR3 slot. In fact, it will more than likely destroy the ram.

This article presents you a comparison between DDR3 and DDR4, highlighting the important differences between both RAMs. However, before delving into the difference between DDR3 and DDR4, let us see the specifications of both RAMS. As a matter of fact, DDR, which stands for Double Data Rate, is a specification used for RAM. DDR4 is the successor of DDR3 and hence consists of improvements in factors such as power consumption, size, speed and efficiency. DDR4, which was released this year, is still not much famous in the market but, in the next year, it will soon outstand DDR3. DDR4 RAMs consume less power than DDR3, but their speed is much higher. Also, the memory density allowed is higher in DDR4. The physical length of DDR3 and DDR4 are the same, but they are not backward compatible as the standard is different. Therefore, the notch in DDR3 and DDR4 are at different places and a DDR4 module will not fit into a DDR3 socket and vice versa.

What is DDR3?

DDR3, which stands for Double Data Rate Type 3, is a type of Dynamic Random Access Memory (DRAM) that came as the successor of DDR and DDR2. It was released to the market in 2007 and today almost all computers and laptops in the market uses DDR3 as the RAM. The voltage specification for DDR is 1.5 V and, therefore, it consumes very less power when compared to its predecessors. DDR3 standard allows chips up to capacity 8 GB. DDR3 RAM are available for different frequencies such as 800, 1066, 1333, 1600, 1866, 2133 MHz. A DDR3 RAM module used for personal computers has 240 pins and the length is 133.35 mm. The DDR3 modules used on laptops are called SO-DIMM and its length is much smaller with a length of 67.6 mm and less number of pins that is 204 pins. There is a special version of DDR3 RAMs called DDR3 low voltage standard, which uses just 1.35 V instead of 1.5 V and is used in some mobile devices to achieve better battery life.

What is DDR4?

DDR4 was introduced this year (2014) as the successor to DDR3. Still DDR4 is not much famous in the market because it was just released a few month ago and hence the motherboards in the market still supports only DDR3. However, after a few months , DDR4 will surely take over DDR3. DDR4 stands for Double Data Rate Type 4 and it has several advancements and improvements over DDR3. DDR4 supports higher memory densities up to 16 GB. The frequency in which DDR4 modules are available is higher than what DDR3 supports and the values available are 1600, 1866, 2133, 2400, 2667, 3200 MHz. The power consumption is further reduced as the voltage specification is 1.2 V. The lengths of DDR4 modules are same as the respective lengths of DDR3 module, but the number of pins is increased. The version used for PCs have 288 pins while the SO-DIMM modules used for laptops have 260 pins. A Low voltage standard DDR4 RAM, which would use about 1.05 V, will be available targeting for mobile devices that needs better power efficiency.

What is the difference between DDR3 and DDR4?

• DDR4 is the successor of DDR3.

• DDR3 was introduced back in 2007 while DDR4 was introduced in 2014.

• DDR3 supports memory densities only up to 8 GB, but DDR4 supports memory densities up to 16 GB.

• The speeds or the frequency of DDR4 RAMs are much higher than the frequency of DDR3 modules. This makes DDR4 much faster by providing better transfer rate.

• DDR3 works at a voltage of 1.5V while DDR4 works at a lesser voltage, which is 1.2V making it more power efficient.

• There is a special version of both DDR3 and DDR4 called low voltage standard, which uses lesser voltage hence lesser power. The low voltage standard of DDR3 uses 1.35V while it is 1.05V for DDR4.

• DDR3 modules have only 240 pins, but DDR4 modules have 288 pins.

• Both DDR3 and DDR4 have a smaller sized module known as SO-DIMM used for mobile devices such as laptops. SO-DIMM DDR3 has 204 pins while SO-DIMM DDR4 has 260 pins.

• DDR3 memory modules are not compatible with DDR4 slots and DDR4 modules are not compatible with DDR3 slots.

• The notch in the DDR3 and DDR4 is placed at different places so that they will not be mistakenly fixed to wrongs slots.

• DDR3 supports only 8 internal memory banks, but DDR4 supports 16 memory banks.

Summary:

DDR4 vs DDR3

Ddr3 Ram On Ddr3l Slot Card

DDR4 being the successor of DDR3 has various improvements. The speed or the frequency of the RAM modules have been much increased in DDR4 giving better transfer rate. A DDR4 module can have a size of 16 GB while this limited to 8 GB for DDR3. However, the power consumption of DDR4 is much less with a 1.2 V voltage used instead of 1.5 V. Therefore, it would be much power efficient providing better battery life for mobile devices. DDR4 memory modules are not compatible with DDR3 slots and vice versa hence the slot on the motherboard determines which type of RAM must be fixed. Currently, the board manufacturers use DDR3 slots but , in the next years, it will transform to DDR4.

Not having enough RAM in your PC can truly wreck your day no matter what you're trying to accomplish. If you're in the market for more RAM, you might be wondering about the differences between DDR3 and DDR4 RAM, and whether or not they really matter to you.

RAM explained

The random-access memory (RAM) in your computer is used to hold data that is frequently accessed by your processor (CPU). It can be likened to your office where you have a corkboard with a bunch of papers on it for easy, quick reference.

Why use RAM when we have hard-disk drives (HDD) and solid-state drives (SSD)? Reading from and writing to a hard drive, even a solid-state drive, is much slower than reading from and writing to RAM. The connection between the CPU and the RAM, also know as the memory bus, is designed for speed, and the entire package uses a small amount of energy to do its job. Accessing a hard drive is sort of like standing up, opening a filing cabinet, and pulling out a paper — much slower than if the paper is already on a corkboard in front of you.

DDR3 and DDR4 RAM don't work together

The first noticeable difference between the two RAM-types is the physical layout of the pins on each module. DDR3 RAM uses a 240-pin connector, while DDR4 RAM uses a 288-pin connector.

Why are they different? A motherboard and CPU that work with DDR3 RAM don't work with DDR4 RAM and vice versa. The different connectors ensure no one accidentally installs the wrong type of memory. Also, take note that not all RAM works with all processors, even if it fits into the motherboard. Take time to research and make sure all parts of your PC are compatible. If you need a hand, PC Part Picker has a wonderful tool that shows you what works together and what doesn't.

You might also hear mention of DDR3L RAM. This RAM has the same pins and works with any CPU and motherboard that works with DDR3 RAM. The difference? DDR3L RAM can function at both 1.5V and 1.35V, while DDR3 RAM is stuck at 1.5V.

DDR4 RAM looks faster on paper

When studying data transfer rates of RAM, you'll see it measured in either million transfers per second (MT/s) or gigatransfers (billion) per second (GT/s). A higher transfer rate means you have more bandwidth and will thus be able to transfer more data at once. DDR4 RAM can transfer data at a rate between 2133MT/s and 4266MT/s, while DDR3 RAM can only hit transfer data rates between 800MT/s and 2133MT/s.

Another number you'll see is the clock speed, which is how fast the RAM can read and write data. The clock speed number, represented in megahertz, is the number of cycles per second the RAM can perform.

Finally, Column Access Strobe latency, also known as CL, must be taken into consideration. CL is the number of clock cycles it takes for the RAM to deliver a piece of data requested by the CPU. Even if you have blazing fast clock speeds, high latency will put a damper on your RAM party.

If we compare four types of Corsair RAM, it's evident that a higher clock speed and the higher transfer rate afforded by DDR4 RAM doesn't necessarily always make it better.

When shopping for RAM, always take all specifications into consideration. Higher numbers on the label don't necessarily mean faster performance.

DDR4 RAM uses a lower voltage

The standard voltage of DDR3 RAM sits at 1.5V, while DDR3L RAM can use both 1.35V and 1.5V. DDR4 RAM, on the other hand, uses 1.2V. While this isn't a big difference for most of us using one or two RAM modules — you're not going to see a difference on your electricity bill — server farms with thousands of RAM modules will definitely enjoy sucking less power.

DDR4 RAM costs more

Are Ddr3 And Ddr3l Compatible

When DDR4 was first released, the price gap was quite large. The gap has shrunk a lot since then, but in general, DDR4 RAM still costs more.

If we look at the prices of the Corsair Dominator Platinum RAM from the table above, it's clear that even though the DDR3 RAM performs better when considering clock speed versus latency, it is still cheaper — DDR3 costs about $115, while DDR4 costs about $130. Again, this isn't a huge difference if you're only buying one or two modules, but in instances where you need a lot of RAM, the cost can really add up.

So...which RAM do I choose?

Going with DDR3 or DDR4 RAM really depends on what other hardware you're currently using, and what hardware you plan on using in the future.

If you have an aging motherboard and a 4th- or 5th-generation Intel CPU, you'll probably be going the route of DDR3 once you figure out all the compatibility stuff. If you have a recent motherboard and, say, a 6th-generation Intel CPU, DDR4 RAM is a good investment for the future — it's hard to believe DDR4 RAM won't be used for quite some time to come.
