Upgrading to this RAM chip from previous generations will dramatically increase memory speed and provide power-saving enhancements. While a DDR3 module uses 1.5V, DDR2 and DDR use 1.8V and 2.5V respectively, so upgrading to DDR3 will significantly lower your power consumption. DDR4 is the fourth generation of DDR RAM to be introduced on the market. It has a larger capacity than its predecessors, the DDR, DDR2, and DDR3. The DDR3 uses about 30% less power and is two-times faster than its predecessor, the DDR2. The DDR2 has a RAM speed of 3200 megabytes per second (MBps) while DDR3 can achieve 6400 MBps. Essentially, if you have a computer with a DDR3, it will process files twice as fast as a DDR2 equipped machine.
Although they are rare, you can get motherboards that can accommodate DDR3 and DDR2 simultaneously. This would be a perfect way of boosting the memory of your computer without incurring huge costs. However, this chip has the same latency as DDR3 and DDR4. Also, it is not compatible with most RAM chips, though computer manufacturers are starting to develop components that can accommodate DDR5. DDR3 memory chips come in different specs depending on their speed. DDR3-800 indicates that it has an 800 million per second bandwidth at 6400 MBps. This is the lowest speed DDR3, and the highest in the DRR3-12800, with 1600 million per second bandwidth at 12800 MBps. What is DDR4?As much as these two chips are different, they also have some things in common, as discussed below. Energy Efficiency We understand that you are not necessarily a tech guru, but you still need to understand the right RAM chip for your device, the options available on the market, and how they affect the efficiency of your device. Let's answer some common relevant questions for your deeper understanding in this section. Is 8GB DDR4 Better Than 16GB DDR3? The SDRAM of your machine determines its memory speed and how much data you can store on your machine. Choosing the right one for your needs is important so that you can process data at optimal speeds and keep your costs at manageable levels. Like the DDR3, DDR4 is offered with a range of specs. The DDR4-2400 is the smallest, while the DDR4-4400 has the highest speed and bandwidth. The 288-pin interface makes this chip highly efficient. The pins are arranged in a way that makes it easy for you to fix the chip on your machine. Also, you cannot mistakenly fix it on an incompatible slot as they are shaped differently not to fit on any other slot other than a DDR4 slot. Power Consumption
Power consumption is usually one of the things that necessitate manufacturers to upgrade earlier versions of their electrical products. There are potentially other differences as well. It's possible to get larger DDR3 memory modules, but many won't work in standard desktop motherboards. The Core i7-4770K officially lists 32GB as the maximum supported RAM, while i7-6700K doubles that to 64GB. Core i7-8700K meanwhile doubles again to 128GB, helped in large part by the availability of higher capacity DIMMs. There are DDR3 RAM chips with varying capacities on the market. You can choose DDR3-800 if you don't work with large files. And if you need more space but aren't ready to upgrade your motherboard, you can upgrade to a higher capacity DDR3 chip such as DDR3-1600. This memory saves energy in three ways. First, it uses little energy to run. It also allows the host device to hibernate to a standby mode without refreshing the memory. Its effective heat distribution mechanism keeps the device cool, which cuts the power needed to run the fan by 40-50%. Bottom Line
One other thing that DDR3 and DDR4 have in common is the heat distribution capacity. Proper management and distribution of electrical heat bring down the risk of your computer overheating or overworking its fan. Advantages of DDR3 When upgrading your computer memory, latency should be one of your considerations. Although the latency difference between DDR3 and DDR4 is not remarkable, DDR4 does come out on top with a latency of 12.75 nanoseconds. What About DDR5? The DDR4 consumes less power than the DDR3. Manufacturers of these memory chips ensure that with every upgrade, they incorporate a power-saving component. That is why the DDR4 is a lower voltage than the DDR3, which in turn uses less power than the DDR2 and DDR.
