What is the confusion about RAM?

Most computer users do a little research before upgrading their system to find out exactly about a perfect combination of CPU, motherboard, and video card that will meet all of their needs. But most of them fail when it comes to RAM. They only know the size of the RAM, that is, 1GB, 2GB or 4GB, but they do not know what this DDR1, DDR2 or DDR3 is about. So that’s why I came up with an idiotic guide to buying a RAM, because it turns out that selecting the proper DDR variant is a very important factor in determining how your system will perform overall, so all computer users should be fine. informed to learn. that.

DDR1 Specifications

DDR-DIM (Double Data Rate DIMM or DDR DIMM) or, more popularly, Single DDR. Dual data rate interfaces provide two data transfers per differential clock. Data is recorded when CK rises [the + side]y / CK low [the – side]. DDR1 uses the JEDEC standard for double date rate [DDR I] SDRAM. Like all DDR RAM, it is available as registered or unbuffered. Registered DIMMs are generally known as FB-DIMMs and have their address and control lines buffered to reduce signal load. FB-DIMMs are considerably more expensive than unbuffered DIMMs and are generally reserved for server use. There are very few enthusiasts / prosumers / gamers who use FB-DIMMs in their CPUs. Unbuffered DIMMs do not have address lines or control line buffers, so they cost significantly less. However, they can be limited by system load and are therefore generally restricted in the number that can be installed on a system. You will find that most unbuffered DIMMs these days can only be installed on one motherboard up to a maximum of 4 x 1 GB. Registered or buffered DIMMs do not have these limitations, and server boards can accommodate 8 x 1 GB, 16 x 1 GB, or more. An interesting and largely unknown aspect of unbuffered DDR DIMMs is that they can operate a faster clock cycle than FB-DIMMs.

DDR2 Specifications

DDR2 memory is the second generation of DDR memory. DDR2 starts with 400MHz speed level as the lowest available, while 400MHz speed is actually the highest speed for DDR1. Therefore, DDR2 picks up where DDR1 ends. It’s a bit strange, but due to different latencies, a 400MHz DDR1 will outperform a 400MHz DDR2, but the advantage returns to DDR2 as soon as the speed reaches the next step of 532MHz, which DDR1 cannot reach.

DDR3 Specifications

DDR3 is the third generation in DDR memory. DDR3 starts with a lower capacity level of 800 Mbps and goes up to 1600 Mbps with a bus speed of up to 2000 MHz. The biggest benefit with lower power consumption is the biggest benefit, as the operating voltage is only 1.5V for DDR3 compared to 1.8V for DDR2. Less heat is generated, which means systems will run cooler. Ultimately, the new technology will result in higher capacity modules: modules up to 8 GB (with 4 Gb chips) to help reduce server / workstation system costs.

Transfer fees

Another confusion is that RAM is primarily concerned with number of PCs, so here are the Transfer Rates for the various DDRs:

DDR1 transfer rate

DDR SDRAM: Double Data Rate SDRAM (DDR200, DDR266, DDR333 are standard) PC1600 (DDR-200 SDRAM); Clock speed: 100 MHz, data rate: 200 MHz, performance 1600 MB / s PC2100 (DDR-266 SDRAM); Clock speed: 133 MHz, data rate: 266 MHz, performance 2100 MB / s PC2400 (DDR-300 SDRAM); Clock speed: 150 MHz, data rate: 300 MHz, throughput 2400 MB / s PC2700 (DDR-333 SDRAM); Clock Speed: 166MHz, Data Rate: 333MHz, Performance 2600MB / s PC3000 (DDR-366 SDRAM); Clock speed: 183 MHz, data rate: 366 MHz, performance 2900 MB / s PC3200 (DDR-400 SDRAM); Clock speed: 200 MHz, data rate: 400 MHz, throughput 3200 MB / s

DDR2 transfer rate

DDR2 SDRAM: Double Data Rate SDRAM II (Quad Edge Clock, 1.8V Signaling), PC2-3200 Second Generation (DDR2-400 SDRAM); Clock speed: 100 MHz, data rate: 400 MHz, performance 3200 MB / s PC2-4300 (DDR2-533 SDRAM); Clock speed: 133 MHz, data rate: 532 MHz, performance 4300 MB / s PC2-5300 (DDR2-667 SDRAM); Clock speed: 167 MHz, data rate: 667 MHz, performance 5300 MB / s PC2-5400 (DDR2-675 SDRAM); Clock Speed: 167MHz, Data Rate: 667MHz, Performance 5400MB / s PC2-6400 (DDR2-800 SDRAM); Clock speed: 200 MHz, data rate: 800 MHz, throughput 6400 MB / s

DDR3 transfer rate

DDR3 SDRAM: Double data rate SDRAM III (four edge clock frequency, 1.5v signaling), 3rd generation PC3-6400 (DDR3-800 SDRAM); Clock speed: 100 MHz, data rate: 800 MHz, performance 6.40 GB / s PC3-8500 (DDR3-1066 SDRAM); Clock speed: 133 MHz, data rate: 1066 MHz, performance 8.53 GB / s PC3-10600 (DDR3-1333 SDRAM); Clock Speed: 166MHz, Data Rate: 1333MHz, Performance 10.67GB / s PC3-12800 (DDR3-1600 SDRAM); Clock Speed: 200 MHz, Data Rate: 1600 MHz, Throughput 12.80 GB / s
Now it will be very difficult to list which RAM is best suited to which motherboard. Before purchasing RAM, you should research your CPU manufacturer’s RAM recommendations and put that exact type of DDR in it. It would be just as silly to use a PC3-12800 DDR3-1600 with an AMD Sempron 2800+ as it would be to charge your Intel QX6800 with a PC1600 DDR-200. Each CPU / chipset combination has its proper DDR setting, and you need to figure out exactly what they are and stick with them. Triggering slower than recommended DDR on your system will kill critical RAM functions and could slow down your system.

Major Manufacturers

Here is the list of some of the main ones, as buying a RAM from an unknown vendor would end in warranty problems.

Kingston

Privateer

Patchwork quilt

Crucial

OCZ

Patriot

By following these guidelines and thoroughly researching the right DDR for your system, you will enjoy years of fast, trouble-free computing. A little study is a small price to pay!
