can ddr4 fit in ddr3 ram slot

can ddr4 fit in ddr3 ram slot?

Using DDR3 in a board with only DDR4 memory slots is not possible. They will not fit and will not work.   Since DDR4 has 288 pins and DDR3 has 240 pins, it can’t work. This is true even though DDR3 and DDR4 are dual channel. It isn’t possible to interchange DDR3 and DDR4 RAM, since they are different types of RAM. DDR3 RAM sticks can’t be placed in DDR4 slots, since they aren’t backwards compatible. In the unlikely event that you wedge it in somehow, the format won’t be recognized by your motherboard. If you want to make sure that you don’t damage anything, use the RAM that your motherboard supports

How will I know if my system supports DDR4? Can I install a DDR4 DIMM on a DDR3 slot?

DDR generation differs from generation to generation. A DDR4 DIMM cannot fit into a DDR3 DIMM slot because DDR4 is not backwards-compatible with DDR3.  This also means that DDR5 RAM kits cannot fit in DDR4 RAM motherboards. There are differences in the pin size and arrangement of DDR3 and DDR4 as well as the key notch (see Figure 1). DDR4 modules feature longer pins towards the middle, giving them a slightly curved “V” shape. Ensure the DDR4 slot on your motherboard is labelled correctly according to its documentation. Also related: Best RAM for ASUS ROG Strix X570-E Gaming

How can I choose which DIMM type to use on my system?

Each DIMM type serves a specific purpose. Depending on the DIMM, either error-correcting code or non-error-correcting code is present. You can choose unbuffered or fully buffered modules (UBIMM/FB-DIMM), registered modules (RDIMM), or load-reduced modules (LR-DIMM). You should check your motherboard’s support for the types of DIMMs that it supports, as different platforms will accommodate different memory types. ATP Blog’s “Understanding RAM and DRAM Computer Memory Types” provides an overview of common types of memory. Also related: best RAM for gaming laptops

On the same system, can DIMMs of different rates be combined?

Installing identical DIMMs on the same system is recommended for best performance. Unless you overclock the slowest DIMM, when mixing DIMMs with different operating speeds, the motherboard will underclock the faster one in order to use only the speed of the slowest DIMM. Guidelines for DIMM population may differ based on which platform you are using. For more information, consult the documentation for your server motherboard.

DDR3 VS DDR4 ram

How does DDR4 differ from DDR3? In the past few years, DDR3 had a good run, but DDR4 has taken its place. The first DDR3 memory was released in 2007 and was used in Intel’s LGA1366 through LGA1151 processor families (6th/7th Generation Core only), AMD’s AM3/AM3+ and FM1/2/2+. Modern platforms (as of 2017) are only DDR4 capable, and Intel 6th Gen Skylake CPUs have removed the DDR3 support. For example, 8th or 9th generation Core CPUs or AMD Ryzen processors require DDR4.

Is there really such a big difference between DDR3 and DDR4 on older CPUs, and are older CPUs more susceptible to CPU overheating? In short, there are differences between the two, but in most cases, your motherboard will decide what you should buy. It is not possible to use DDR3 on a motherboard with DDR4 slots and you cannot use DDR4 on a motherboard with DDR3 slots. We’ll explore each difference further.

Voltage difference

Your DDR4 and DDR3 operate at different voltages.

The normal voltage for DDR4 is 1.2 volts. The normal voltage for DDR3 is 1.5 volts.

While it may not seem like much, you can find DDR3L modules at low voltage and enthusiast DDR4 modules with overlapping voltages.

Modules are available with 1.5V and 1.2V voltages.

A 15W savings over DDR3 could be attributed to the voltage difference-a small amount for you as a home user.


Additionally, DDR3 and DDR4 differ greatly in speed. The official DDR3 specification starts at 800 MT/s (or Millions of Transfers per Second) and ends at DDR3-2133. It has been reported that some overclocked modules reached speeds as high as DDR3-3200, although that is not officially supported.

According to official data, DDR4 runs at 1600 MHz with a maximum speed of 3200 MHz. In overclocking kits, the speed can be increased to DDR4-4800. With the increased speed, the bandwidth also increases.


Unfortunately, this will also increase latency. DDR3 is usually faster than DDR2 , but maintains a latency comparable to its predecessors.

A read from a DDR3-1600 CL10 module has a 12.5 nanosecond latency, for example. There is a 12.75 nanosecond latency for DDR4-2666 CL17, which is essentially the same. However, the DDR4 has a faster bandwidth than the DDR3 at 21.3 GB/s compared to 12.8 GB/s.

Can a Motherboard Support DDR3 and DDR4 RAM at the Same Time?

There aren’t any motherboards that support both DDR3 and DDR4. Most motherboards only support one or the other, although there are some rare motherboards that support both.

Therefore, if you have both kinds of RAM on hand, you can’t combine them.

Can DDR3 RAM Work In DDR4 Slot? (Can DDR3 Fit In DDR4?)

Since the two are vastly different, the short answer is NO. Furthermore, you should know that a computer that supports DDR4 memory will be incompatible with a motherboard with DDR3 slots. This can be better explained if you take a closer look at the functionality below. In the first place, there is no doubt that DDR4 runs at a significantly lower voltage than DDR3. This results in greater performance and reduced power consumption.

Which One Is Better?

What is the relationship between real-time performance and this? In real time how does it impact performance? Which one stands out for you? This is a more complex question than you might think. According to statistics, the amount of increase in application performance is relatively small, and there is rarely more than a few percentage points between the two.

Is DDR3 RAM  still good in 2021?

The DigiTimes reports that DDR3 is projected to grow by 40-50% between now and 2022.

Despite the lack of new systems that are compatible with DDR3, the older memory technology still retains a decent amount of popularity. However, for the best performance in your Ryzen 9 3900x cpu choose best DDR4 RAM instead of DDR3. There is a significant performance difference.

Ddr3 vs ddr4 gaming

The average gamer perceives DDR3 as an obsolete memory technology, and DDR4 is a near-necessity when upgrading or building a PC. Why is the latter necessary, and if so, what is the difference between the two?

It is primarily a matter of energy efficiency and transfer speeds that differentiate Double Data Rate Third Generation (DDR3) from Double Data Rate Fourth Generation (DDR4). If you are going to upgrade 16GB of RAM from DDR3 to DDR4, then you should really only focus on those transfer speeds since the energy savings are minimal. But let’s take a closer look at why modern rigs use DDR4 and why it’s becoming the standard.

Is ram backward compatible

It is more appropriate to ask if DDR4 is backward compatible with DDR3, DDR2, and DDR1. There is no mutual compatibility among DDR memories. DIMMs for DDR2, DDR3 and DDR4 can only be used in their respective sockets, with notches positioned differently from one another. The power supply varies for each generation as well: it is 2.5V for DDR1 DIMMs; 1.8V for DDR2 DIMMs; 1.5V for DDR3 DIMMs; and 1.2V for DDR4 DIMMs.  We have answered your question on  can ddr4 fit in ddr3 ram slot.
