If you want to select the best RAM for your PC build, this is the simplest and most useful guide you’ll find anywhere. There’s nothing else you’d ever want or need to buy.

When it comes to a computer’s overall performance, the RAM is third most important after the central processing unit and graphics processing unit.

RAM modules and kits, like CPUs and GPUs, have a plethora of technical terms and features that the average gamer may not understand.

So, How does one go about picking out RAM? After doing some reading, constructing or upgrading a computer is as easy as assembling a Lego model.

Please refer to this RAM buying guide for assistance.

What Is RAM?

Among its many meanings, RAM stands for a storage medium that allows for random access and describes a type of short-term storage employed by computers. RAM is constantly being overwritten and refreshed because its sole purpose is to provide a CPU with fast access to data without permanently storing it.

Still, it’s a big deal faster than the use of a permanent storage solution. However, the main drawback is that it can only temporarily store data while it is powered, which rules out any use as long-term storage.

When using a computer, why is it crucial to have a large amount of RAM?

We know it’s used to keep track of data that the central processing unit (CPU) or graphics processing unit (GPU) frequently accesses. Since this is the case, it is essential for effective multi-tasking, such as maintaining a large number of simultaneously open programs. To put it simply, it stores all the game’s assets in a way that allows for rapid access during play.

Laptop and Desktop RAM

RAM for laptops and desktops are physically distinct due to their respective sizes and pinouts on the motherboard connectors.

Typically, laptops are able to in common parlance SO-DIMM While desktop computers use SO-DIMMs (Small Outline Dual In-Line Memory Module), DIMM RAM (Dual In-Line Memory Module) module UDIMM. SO-DIMM is, as the name implies, a reduced-size form of the more common DIMM.

SO-DIMM is about half the size of DIMM, measuring 2.74 inches in length as opposed to the standard DIMM length of 514 inches, to accommodate the limited space of laptop computers. There are 260 pins on an SO-DIMM and 288 on a DIMM.

It goes without saying that you should take care not to purchase the wrong type of RAM because laptops cannot fit DIMM memory and desktops cannot fit SO-DIMM memory. Fortunately, you can tell the difference between the two right away.

Choosing The Right Type of DDR

These days’ RAM isDDR SDRAMDDR, DDR2, DDR3, and DDR4 are the four iterations of computer memory used in the past two decades.

The fourth-generation processor is used in nearly all new machines. DDR4 by which widespread use can be assumed to have occurred by 2016 at the latest. While DDR3 memory and motherboards that support it are still widely available, the technology is rapidly becoming outdated.

Keeping the technical details at bay, suffice it to say that DDR4 is a vast improvement over its forerunner in terms of speed and nearly every other metric.

Something to keep in mind is that DDR4 isn’t compatible with older motherboards and CPUs, and vice versa for DDR3. Therefore, In other words, you can’t use DDR4 with a motherboard that only supports DDR3, and you can’t use DDR3 with a DDR4-compatible board..

Motherboard Form Factor and Slot Count

Determining regardless of whether you have a DDR4 or DDR3 motherboard, is easily understood: look forIndicators of the Systemin addition to the subOverview of the System,The motherboard model can be determined by looking at theMethodology Model field. Then, simply locate that model on the producer’s site and review the spec sheet for further details.

The following is the capacity of Random Access Memory Slots which can be seen clearly from the motherboard or the official website. Slot availability can change depending on the motherboard’s physical layout.

In contrast to the four supported by ATX and Micro ATX motherboards, two are all that Mini ITX boards can handle. Additionally, two-slot models are a real possibility. In addition, some EATX motherboards feature as many as eight RAM slots, but such a large amount of memory is not required for gaming rigs.

However, availability of actual slots isn’t everything. The maximum amount of Random Access Memory that a given motherboard can accommodate, and you can find this information out with the aid of a specs sheet as well.

You shouldn’t have to worry about this if you’re putting together a gaming PC, as it’s unusual to come across a modern motherboard model that doesn’t support 32 GB of RAM.

CPU and OS Limits

RAM and central processing units both have their limits. Modern 64-bit CPUs, such as the latest 9th generation Intel Core and the 3rd generation AMD Ryzen, typically support up to 64 GB or 128 GB of RAM, so this limit won’t be an issue even with motherboards.

If your computer has a 64-bit processor, you can safely ignore the RAM restrictions set by the processor and the operating system  as 16 GB of RAM is generally sufficient for gaming PCs. However, if you’re working with an older CPU, double-checking is always a good idea.

Clock Speed

The clock speed of a RAM module, measured in megahertz (MHz), is equivalent to the clock speed of a central processing unit (CPU) or graphics processing unit (GPU) and thus directly correlates to performance. Higher clock speeds are preferable in every scenario, but In video games, storage space and loading times are secondary to capacity.

There is some truth to the idea that faster RAM with a fancier heat spreader will provide better performance, but the difference is negligible at best (a couple of frames), so it’s not worth spending the extra money on.

Because, at the end of the day, DDR4 is DDR4, and For gaming purposes, the difference between RAM speeds of 3200 MHz and 2400 MHz is negligible..

Bandwidth – Single Channel vs Dual-Channel vs Quad-Channel

Dual-channel RAMhas been around for some time, and its main draw is increased data transfer speeds. To be more specific, there is a limit to how much information can be sent between a central processing unit and a single piece of random access memory. As a result, multi-channel configurations like dual- and quad-channel setups are introduced to avoid bottlenecking.

To put it simply, dual-channel configurations employ two RAM sticks, while quad-channel configurations employ four. There are more modules, so this can improve Increase the data transfer rate and capacity.

When it comes to video games, however, all that extra bandwidth is largely irrelevant. The majority of servers and workstations require multi-channel RAM using a program that requires a lot of memory to run and moves around a lot of data.

While the performance gains from using dual or even quad channel RAM for gaming may be negligible, there are still advantages to using more than one RAM module.

The initial issue is the cost  In most cases, purchasing a number of smaller modules is more cost-effective than purchasing one larger module. If you needed 16 GB of RAM for your PC build, but didn’t want to spend quite as much, you could save money by purchasing a 2×8 GB or 4×4 GB kit instead of a single 16 GB module.

Kits are not always more cost effective than purchasing components singly because of fluctuations in supply and demand.

To add to that, RAM sticks are more easily and inexpensively replaced if there are at least two or four of them. There is no denying that RAM modules with less storage space available are less expensive. Also, if you have a 2 GB kit and one of the modules fails, you can continue using the computer with 8 GB of RAM until you can get the replacement module.

In contrast, if your computer only had a single 16 GB RAM stick and that one failed, you would be without a working computer for quite some time.

Timings and Latency

CAS/CL represents latency, or the time it takes for the processor to access the data after issuing a read command. Latency in synchronous DRAM, such as DDR4, is expressed in clock cycles rather than nanoseconds.

But without getting into the weeds here, suffice it to say that For the average gamer, latency isn’t a big deal similar to CPU speeds and data transfer rates Spending more money on reducing latency for gaming barely makes a difference in terms of performance, so capacity should still take precedence.

RAM Capacity

As we have mentioned before, capacity is the most crucial aspect of gaming, and right now, 16 GB represents the ideal sum In 2022, 32 GB of RAM or more will be overkill for a gaming PC, while 8 GB will likely be insufficient.

You could start with 8 GB and add more later, or you could go as high as 32 GB if you want a more future-proof setup and plan to use RAM-intensive programs.

How to Choose RAM: 4 Things to Consider Before Buying

However, the graphics processing unit (GPU) and central processing unit (CPU) are more important components of a gaming PC; don’t skimp on those for the sake of more RAM, even if that RAM is being purchased solely for the sake of future-proofing. If you ever find that 16 GB of RAM is insufficient for your needs, as was mentioned above, you can simply install more memory into your computer.

And yet, You should prioritize upgrading your CPU or GPU over your RAM because these components are more difficult to upgrade..

What to Look for in RAM

Speed-You can certainly delve deeper into the details, but larger numbers still generally yield improved performance. For instance, while 8GB RAM may be adequate for basic computing tasks, 16GB RAM should have you sailing smoothly through multitasking and demanding computing needs. If more RAM can be installed, do so. The rate at which time passes is also significant. Better performance from a smaller amount of RAM is preferable to a larger amount of subpar RAM.

Harmony –The newer DDR4 RAM is much faster than the older DDR3 RAM, but your motherboard might not be able to handle it. Make sure the RAM you want to buy is compatible with your computer before you make the purchase.

Size –Measurements are being made here in terms of actual body dimensions. Standard-sized RAM may not leave enough room for a sizable CPU cooler, for example, if you’re trying to pack your PC tower with high-end gaming components. Consider using low-profile RAM in this situation, which can give you some breathing room when trying to fit it in with other parts. However, a different type of RAM called a SODIMM is used in laptops and Macs.

Closing Thoughts

Finally, it’s worth noting that while it’s technically possible to switch between models, doing so is not advised. There is always the risk of unexpected crashes, bugs, and instability when mixing RAM modules from different manufacturers.

Plus, if you’re using modules with varying clock speeds, you’ll be limited to the lowest-performing module’s speed.

This brings us to a conclusion: Don’t mix and match different models if you end up upgrading your RAM in the future; instead, prioritize capacity over speed and latency, choose kits over individual high-capacity modules, leave expansion room if necessary/possible, and so on..
