Unlike HDDs or SSDs, RAM is a type of <strong>volatile memory<\/strong>.<\/p>\n<p>This means RAM can only store data if it's supplied with electricity (the computer is turned on).<\/p>\n<p>As soon as your computer turns off, all the data stored in RAM is lost. Therefore, you can\u2019t use RAM for long-term storage like HDDs or SSDs despite being among the fastest type of storage.<\/p>\n<p>You can think of RAM as short-term, temporary storage, while HDDs and SSDs are long-term storage units.<\/p>\n<p>So, what type of files does your computer save to RAM for quick access?<\/p>\n<p>When you open any program on your computer, your hard drive or SSD transfers the program\u2019s essential data to the RAM.<\/p>\n<p>The CPU can then access the data from RAM and run the program.

But how is this possible?<\/p>\n<p>There are two clocks involved in what makes DDR RAM work. An internal memory clock and the external bus that connects the RAM to the rest of your system.<\/p>\n<p>DDR2 kept the memory clock the same as DDR. However, the external bus clock was doubled. This means that the external bus has double the data capacity per second.<\/p>\n<p>As such, the internal memory cell array, where the data is stored, doubles the number of bits delivered at one time to the external memory bus.<\/p>\n<p>This process is also known as <strong>prefetching<\/strong>, and it\u2019s why DDR3 is faster than DDR2 and why DDR2 is faster than the first generation of DDR.<\/p>\n<p>Because the external bus has a faster clock, it can carry the extra data, which gives you faster memory.<\/p>\n<p>DDR4 works slightly differently because the memory arrays are divided into bank groups, meaning prefetches can be extracted from different RAM parts simultaneously, leading to higher speeds than even DDR3.<\/p>\n<p>DDR4 SDRAM is the most common type of RAM used in computers as of 2022.<\/p>\n<p><a href=\"https:\/\/g100.us\/ddr4-vs-ddr5\/\">DDR5<\/a> was recently released but will take some time to come down in price and at the time of this writing, is still too

The main RAM in all modern computers is DRAM because DDR SDRAM is just an evolved version of DRAM.<\/p>\n<p>DRAM is labeled <strong>dynamic <\/strong>because it requires a periodic refresh of power to function. It continuously refreshes 100 or more times per second.<\/p>\n<p>DRAM uses transistors and capacitors to store data. The capacitors that store data in DRAM slowly release energy. If there is no energy released, the data gets lost.<\/p>\n<p>Compared to SRAM, DRAM is less expensive to manufacture and has greater memory capacities. However, the disadvantages are that DRAM has slower access speeds and higher power consumption.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"SRAM_Static_RAM\"><\/span>SRAM (Static RAM)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><em>(Introduced in 1963)<\/em><\/p>\n<div id=\"attachment_16468\" style=\"width: 2560px\" class=\"wp-caption alignnone\"><noscript><img aria-describedby=\"caption-attachment-16468\" decoding=\"async\" class=\"size-full wp-image-16468\" src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-scaled.jpg\" alt=\"Hynix HY62V8100B SRAM\" width=\"2560\" height=\"1920\" srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-scaled.jpg 2560w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-300x225.jpg 300w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-1024x768.jpg 1024w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-768x576.jpg 768w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-1536x1152.jpg 1536w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-2048x1536.jpg 2048w\" sizes=\"(max-width: 2560px) 100vw, 2560px\"><\/noscript><img aria-describedby=\"caption-attachment-16468\" decoding=\"async\" class=\"size-full wp-image-16468 lazyload\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%202560%201920%22%3E%3C%2Fsvg%3E\" alt=\"Hynix HY62V8100B SRAM\" width=\"2560\" height=\"1920\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%202560%201920%22%3E%3C%2Fsvg%3E 2560w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" data-srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-scaled.jpg 2560w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-300x225.jpg 300w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-1024x768.jpg 1024w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-768x576.jpg 768w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-1536x1152.jpg 1536w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-2048x1536.jpg 2048w\" data-src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/SRAM-scaled.jpg\"><p id=\"caption-attachment-16468\" class=\"wp-caption-text\">Image Credit: <a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:Hynix_HY62V8100B_SRAM-7313.jpg\" target=\"_blank\" rel=\"noopener\">Wikimedia<\/a><\/p><\/div>\n<p>Unlike DRAM, Static RAM does not need to be refreshed.

class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Fully Buffered DIMM is a RAM chip that contains an advanced memory buffer on the chipset.<\/p>\n<p>The advanced memory buffer functions as a middleman between the memory controller and memory modules.<\/p>\n<p>This allows the available memory on the chipset to be increased without increasing the number of pins on the memory module.<\/p>\n<p>The downside of using an FBDIMM is that it includes the introduction of latency and an increase in the chipset\u2019s power consumption.<\/p>\n<p>This type of memory is typically used in servers to increase the server's memory speed and maximum memory capacity.<\/p>\n<p>The main difference between FBDIMM modules and regular DIMM modules is that on FBDIMM, the communication between the chipset and the module is serial.<\/p>\n<p>Standard DIMM modules use parallel communication.<\/p>\n<p>With serial communication, the number of wires needed to connect the chipset to the memory module is lower, allowing the creation of more memory channels. Therefore, increasing memory performance.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"ECC_Error_Correction_Code\"><\/span>ECC (Error Correction Code)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><a href=\"https:\/\/g100.us\/do-you-need-ecc-memory\/\">Error Correction Code RAM<\/a> is equipped with an extra memory chip that ensures system data integrity by correcting memory errors in real-time.<\/p>\n<p>This particular kind of memory module is used in servers where errors in data could be disastrous.<\/p>\n<div id=\"attachment_16475\" style=\"width: 700px\" class=\"wp-caption alignnone\"><noscript><img aria-describedby=\"caption-attachment-16475\" decoding=\"async\" class=\"size-full wp-image-16475\" src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/ECC-DIMM-ECC-SODIMM.jpg\" alt=\"ECC DIMM ECC SODIMM\" width=\"700\" height=\"472\" srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/ECC-DIMM-ECC-SODIMM.jpg 700w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/ECC-DIMM-ECC-SODIMM-300x202.jpg 300w\" sizes=\"(max-width: 700px) 100vw, 700px\"><\/noscript><img aria-describedby=\"caption-attachment-16475\" decoding=\"async\" class=\"size-full wp-image-16475 lazyload\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20700%20472%22%3E%3C%2Fsvg%3E\" alt=\"ECC DIMM ECC SODIMM\" width=\"700\" height=\"472\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20700%20472%22%3E%3C%2Fsvg%3E 700w\" sizes=\"(max-width: 700px) 100vw, 700px\" data-srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/ECC-DIMM-ECC-SODIMM.jpg 700w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/ECC-DIMM-ECC-SODIMM-300x202.jpg 300w\" data-src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/04\/ECC-DIMM-ECC-SODIMM.jpg\"><p id=\"caption-attachment-16475\" class=\"wp-caption-text\">Image Credit: <a href=\"https:\/\/semiconductor.samsung.com\/dram\/module\/ecc-udimm-ecc-sodimm\/\" target=\"_blank\" rel=\"noopener\">SAMSUNG<\/a><\/p><\/div>\n<p>Consumer motherboards and processors typically don\u2019t support ECC-compatible RAM.<\/p>\n<p>If you\u2019re not building a server that explicitly requires ECC RAM, you probably won't need it.

Laptop DDR4 RAM, on the other hand, houses 204 pins.<\/p>\n<p>SODIMM and DIMM also have different pin arrangements and voltages.<\/p>\n<p>All things being equal, there is no performance difference between desktop and laptop RAM.<\/p>\n<p>For instance, if we took a 3000 MHz DDR4 DIMM module with a CL18 latency and a 3000 MHz DDR4 SO-DIMM module with a CL18 latency, the performance would theoretically be the exact same.<\/p>\n<p>The key difference lies in SO-DIMM's limitations. The fastest DDR4 SO-DIMM modules operate at 4,000 MT\/s, while we can easily find modules in the DDR4 DIMM format with 4,600 MT\/s or higher speeds.<\/p>\n<p>SO-DIMMs also have more <a href=\"https:\/\/g100.us\/single-vs-double-sided-memory\/\">vulnerability to overheating<\/a> because of their size.
