140 Gamers and those performing conventional basic productivity tasks can survive on 8GB. But several open browser tabs and other running programs can use this up very easily. Since you can buy 16GB for just $25 more than 8GB, most should opt for 16GB. Those who are serious about creating content will probably want more. Memory speed is limited, especially with some low-cost mainstream CPUs and chipsets. So if, for example, your system only supports 2,666 MHz, there is no reason to buy RAM with a capacity of 3,600. You will not be able to reach the highest speed and may wind up stuck at an even slower recoil speed. Check the motherboard manufacturer’s specs for supported speeds and buy accordingly. If you plan on playing games without a dedicated graphics card, you’ll get noticeably better frame rates if you opt for faster (compatible) memory. But if you have to spend more on components to support that speed, as well as higher clocked memory, it might make more sense to spend on a dedicated card that will provide better overall gaming performance. The amount of software that makes big gains from faster, more rigid memory kits is actually quite small. Some games will have a benefit as well as compression software like 7-zip as well as some aspects of content creation software. Do research on the programs and games you use most often. If you’re not running memory-sensitive software and you have a dedicated graphics card, you can save some money by opting for slower RAM and spending it on a bigger SSD or a better graphics card or CPU. Generally speaking, most memory doesn’t run fast enough (unless you’re taking it to extreme levels with manual overclocking) to require metal heatsinks. As long as you have some air blowing into the case and memory, you can opt for empty sticks. Obviously, flashing lights don’t alter its performance either. So if your case doesn’t have a window or you don’t care too much about the way your memory looks, there’s no reason not to opt for USB sticks with exposed PCBs and memory banks – as long as it comes in the speed and specs you’re after . The technology that gives the motherboard the correct frequency and timings is called Serial Presence Detect (SPD), and the part it detects is a tiny ROM (read-only memory) chip that has been programmed with a timing table. Industry standard times are defined by the Joint Electron Device Engineering Council (JEDEC), an industry organization that includes companies from the memory controller and CPU industries to DRAM IC manufacturers and assemblers. A list of approved DDR4 modes is frequently updated on Wikipedia. And for the most part, the associated times for standard data rates are dire and optional “better” versions are rarely produced. As explained in our How To Enable XMP, Intel’s “Extreme Memory Profiles” add an overclocking table to memory, occasionally leading to the point that some of the faster DDR4-4266 DIMMs contained DDR4-2133 ICs. If your motherboard supports XMP, you can usually get a kit with a moderate data rate and more restricted latencies than the standard, like DDR4-3200 CAS 14. The problem for those whose motherboards don’t support XMP is that these kits they are usually standard for DDR4-2133 CAS 15. Every current kit with enhanced timings requires XMP to automatically configure these timings, and the Wikipedia entry linked above should help you figure out whether these timings are standard or XMP. Those who chose not to take this risk might want to take a look at the CPU-Z screenshots from our memory tests and choose one of these kits. You will need at least two modules to enable dual-channel mode on platforms such as AMD Socket AM4 or Intel LGA 1151, or four modules to enable quad-channel modes on AMD socket TR4 and Intel’s LGA 2066. These modules can be of single rating ( with all ICs addressed by one of the 64-bit dual interfaces of each module) or dual classification (addressed by both interfaces). After tracking a similar phenomenon on Intel processors for several years, our Ryzen 3000 memory drill has detailed how having two memory ratings per channel offers a significant performance benefit for some applications. We also know from our PC Memory 101 article that two ratings per channel can be achieved by doubling the number of modules or using modules with two ratings. Reasons for choosing the latter include leaving the expansion room in the empty slots of cards that have two per channel, or getting the benefit of two ratings of cards that have only one slot per channel. Also, although you may have read about T vs string topography in our comments or forum, you don’t need to worry about these concepts if you’re only running one DIMM per channel. Intel does not allow overclocking anything other than its Z-series (enthusiast) and X-series (next-gen desktop) chipsets. This leaves conventional buyers who don’t want to spend a lot on the Z series, others features stuck to Intel’s “approved” limits, including its DDR4-2666 maximum for Core i5 and higher processors. We’ve reviewed several of these boards and noticed that most retail parts include Intel XMP. While this does not affect the maximum memory speed, it does allow one-click setup of low latency DDR4-2666. Unfortunately, the market for low latency DDR4-2666 is so small that CAS 12 and CAS 13 kits are no longer in production. CAS 15 timings appear to be the fastest of the parts available today. Intel’s low-end processors have the same chipset-based restrictions we mentioned in the previous paragraph, but with an even lower DDR4-2400 data rate. The market for performance-enhanced memory at this data rate is so small that the lowest latency we can find among current products is CAS 14. The beauty of the DDR4-2933 is that it runs at a full ratio, 11 × 133.333, which is a smaller ratio than the 15 × 100 that the DDR4-3000 uses. We’ve seen some cards that wouldn’t run any louder than this, including Biostar’s award-winning X470GT8. Because it works so well, memory at this data rate was widely available in CAS 15. But then a rumor began to circulate that DDR4-3000 was the sweet spot for Ryzen 2000 series processors, and manufacturers quickly began programming these modules for DDR4-3000 to meet the new demand. A limited range of expensive DDR4-2933 CAS 16 kits remains, although users who are not afraid to experiment can always revert back to their cheaper DDR4-3000 CAS 15 kits to DDR4-2933 if the higher data rate is not stable. By default, the X570 motherboards memory controller switches to half speed and the “Infinity Fabric” interface to an unsynchronized rate when exceeding DDR4-3600 speeds, causing performance to drop when using DDR4-3733 or higher . Many end users are reporting limits between DDR4-3733 and DDR4-3866 after disabling these stability protections, but this small increase in data rate is probably not worth your effort, unless you’re just looking for higher speeds to brag about . our motherboard guides detail the frequency capabilities of at least one configuration for each card we’ve tested, but we can’t test everything. For a quick and dirty look at the current memory landscape, here’s a graph of the RAM kit’s capacities and types currently available, along with the types of systems they work best for. The price ratio is based on the cheapest kit in each configuration.

How to find the correct RAM for PC – Guide
RAM is an acronym for Random Access Memory and refers to a form of temporary memory used by computers. Unlike a hard drive or SSD, RAM is constantly overwritten and updated because its purpose is to allow a CPU to quickly access relevant data without permanently storing it. However, it is much faster than any permanent storage solution. However, the biggest disadvantage and the reason why it cannot be used as a long-term memory is that it can only store data temporarily while it is powered on.
And why is RAM important on a PC? Well, we’ve already established that it’s used to store relevant data that the CPU or GPU needs to access quickly. Therefore, it is crucial for efficient multitasking, that is, opening a large number of programs at the same time and making them run smoothly. For games, it stores all the relevant data that the game needs to access quickly.
