How to choose the best RAM for gaming
With so many choices for gaming RAM on the market, it can be overwhelming deciding what you need. We’ve put together frequently asked questions as well as explanations for the differences that factor into choosing the best gaming PC RAM for your needs.
Why is RAM so important?
Unlike permanent data storage that you get with a hard drive, RAM is the temporary storage medium that helps run open applications. This CNET article elegantly explains the difference between RAM, hard drives, and virtual memory, but essentially, RAM gives your PC the ability to operate applications at an appropriate speed.
If you junk up your PC with multiple running applications, particularly heavy ones, it can really slow down the overall performance of your PC. Depending on the game requirements and your need to multitask, you may need more RAM than you currently have.
Before you buy
Make sure you can identify the kind of motherboard you have. Motherboards contain the installation slots for individual RAM modules, and not all models will fit your PC. DRAM, or dynamic random access memory, has evolved over the years and is labeled by generation – DDR1, DDR2, DDR3, and the most current, DDR4. DDR3 has adequate capacity speed, and latency, while DDR4 runs faster.
The motherboard also ultimately controls the maximum speed available. Make sure you check your motherboard to see what the maximum supported memory speed is. There’s no point in spending money on a 2400MHz RAM if the motherboard can only support 1600MHz.
Also be sure to check your pin output; typically, you’ll see 200-pin and 240-pin in regular sized DDR3 modules, while SODIMM, or small outline dual inline memory modules, are available in 144, 200, and 204-pin outputs. DDR4 now has 288-pin dual inline memory modules.
Kits versus modules
When doing your search for RAM for your PC, it’s important to see if it’s labeled as a kit or not. Modules typically refer to a single piece for your PC installation. Kits indicate that you will be getting more than one module (Two 4GB modules are sold as an 8GB RAM, for example).
Most motherboards have either two or four slots, so it’s important to check before you buy to see if you can accommodate a larger kit size. In terms of performance, the difference between buying kits and individual modules is negligible, but there can be a difference in cost. Buying a single module can sometimes cost more than buying two smaller capacity modules; some people may choose to buy two separate modules to save a little more on their budget, but it’s recommended to go with a kit if you’re plan on buying multiple modules.
A kit contains identical modules that have been tested to work together, whereas piecing together different modules may not work as well or give you the same performance. Kits ensure that the modules were produced from the same production batch.
Consider your budget. Larger capacity memory kits and modules (16GB+) generally become increasingly expensive, and you’ll need to devote part of your budget to the other major components – processors, drives, and graphics cards. The higher the speed and capacity, the more you will see and increase in price.
In addition, there will be a price difference between DDR3 and DDR4 generations of RAM, with the newer, but more powerful and higher performing, costing more than their predecessors. Although we mentioned it earlier, it’s still important to check to speed capacity of your motherboard – there’s no point in investing in a higher speed module if your system can’t handle it.
We’ll discuss it in further detail, but if you don’t need to do things like video editing or heavy multitasking you probably can save on the added expense.
Not all memory kits and modules are created equal
There are many differences in RAM modules that you’ll need to factor into your decision-making. We’ll discuss form, storage capacity, and speed.
Different types of memory kits and modules
As we mentioned earlier, there are four generations of DRAM currently. DRAM is replaceable and modular; you may see some modules with the label DIMM or UDIMM. DIMM stands for dual inline memory module and is the most common form of DRAM for PCs.
DIMM is the generic form of UDIMM, the “U” representing unregistered or unbuffered. There exists RDIMM, meaning registered, but it runs slower than UDIMM. Another option well suited for laptops is SODIMM, or small outline dual inline memory module. SODIMM occupies a footprint about half that of a standard DIMM.
DDR3 versus DDR4
DDR, or double data rate, refers to the function of transmitting data twice per clock cycle, or data rate. The clock cycle is an indicator of the processor’s overall performance and is typically measured in MHz. Data rate can also be measured by bandwidth as Millions of Transfers per second (MT/s).
DDR3, one of the two current DDR iterations, typically runs at a power consumption of 1.5V and have clock speeds as high as 2300MHz. DDR4 runs at significantly higher speeds, starting at 2300MHz. However, speed affects latency. An article by PC Gamer outlines the differences between DDR3 and DDR4 in detail, but ultimately concludes that the difference in performance between equal modules of equal speeds is negligible for the home user.
You will see some difference in terms of power consumption. DDR4 draws a standard voltage of 1.2V, with performance voltage at 1.35V. This makes more of a difference for larger servers, but it is lower nonetheless.
Another great resource for learning more about the differences between DDR3 and DDR4 is this article by AnandTech. You’ll get a detailed analysis of differences in terms of bandwidth and power consumption, and well as analysis of the physical components such as pin contacts and other engineering features.
How much RAM do you need for your gaming PC?
The amount of RAM you need for your gaming PC is based on a few factors. Some people may tell you that you can never have too much RAM, but that’s not necessarily true. RAM kits tend to increase in price the higher the memory storage capacity, which may not leave you with enough funds to support a high-quality CPU, hard drive, and graphics card, all very important to good game performance.
If you have a lower-performing graphics card, it may require you to play games on a less graphically intense level. The lower the graphics requirements, the lower the RAM requirements. However, you need to make sure you have enough to support the processor as to not lose performance in terms of frames per second.
Based on current high-performing games, 4GB is the recommended minimum memory for gaming PCs, but 8GB is generally considered the “sweet spot”, allowing you better performance while running other applications. Some people will tell you that you need 16GB or more, but this can be overkill if you’re not using other heavy applications like video editing.
However, planning for future gaming is another factor to consider. While 4GB may work well for your current needs, games inevitably change and are becoming more taxing on your operating system. Depending on your budget, you may want to invest in RAM with a larger capacity to ensure your gaming PC will maintain high performance over time as games require larger memory capacity.
Check out this informational video from Hardware Unboxed that covers that performance differences by capacity in RAMs for gaming: 4GB, 8GB, and 16GB.
CAS latency, or column access strobe (abbreviated CL), indicates the delay time between when a command is entered versus when it is executed. Latency is that gap between the two. More specifically, the latency is measured by the number of clock cycles the data must go through to complete the command.
To actually determine the true latency, Crucial provides this exhaustive guide explaining CAS latency and related performance. CL only measures the total number of clock cycles, and not the clock cycle duration, thus making CL a sometimes misleading indicator of performance.
The formula for determining true latency when examining the differences between high-performing RAMs should be based on measurements in nanoseconds. Multiply the clock cycle time (in nanoseconds) by the number of clock cycles (CL) to determine the true latency. Official engineering documentation will provide clock cycle timing.
Crucial lays out a chart comparing module speed, clock cycle time, and CAS latency to determine true latency. The results show that in DDR3 and DDR4 RAMs, the true latency is actually lower than in the older DDR1 and DDR2 generations. At this point in time, speeds are increasing without much change to true latency, meaning that you can expect higher performance and overall greater efficiency.
Ultimately, after analyzing engineering differences across multiple modules, we can come to the conclusion that latency, while important, is not as critical a factor as speed.
Voltage refers to power consumption, which contributes to noise and heat production. Standard voltage for most DDR3 RAMs is 1.5 volts, but there are some low-voltage models.
The newer generation of DDR4 RAMs typically runs at lower power consumption. This may not make a huge difference on a home budget, but the difference in power consumption can add up if you have servers. Also, you’ll generally experience less noise interference and lower heat output. Most newer modules operate at 1.2 or 1.35 volts.
Speed is probably one of the most important factors when deciding on the RAM for your gaming computer. Modules from older DDR generations (1 or 2) run at considerably lower speeds with higher latency. Today’s gaming RAMs give you better performance with the ability to run at higher speeds without sacrificing stability.
Generally expect to see modern gaming RAMs with speeds starting at 1600MHz, going as high as 3200MHz. While the RAM speed is important, it’s also important to acknowledge the maximum speed supported by your motherboard. For example, a 3200MHz RAM is fantastic but not useful if your motherboard only supports speeds up to 2133MHz. In general, any frequency over 1600MHz is considered overclocking (OC) RAM.
If you’re interested in overclocking, you should do CPU/GPU research to find units that support faster timings, which will allow you to perform above rated specifications for intense gaming. RAM speed does have some impact on stability. Overclocking on certain systems requires a faster RAM speed to prevent performance issues.
Regardless, check you your motherboard’s compatibility list before you make any final purchases.
XMP Profiles, a redundancy meaning Extreme Memory Profile, allows for automatic overclocking without having to manually make BIOS adjustments. Manual overclocking is common in some of the older DDR RAMs, but most of the modules we reviewed have an automatic overclocking feature.
XMP support means that you have preset memory profiles at your disposal, making performance adjustments a breeze. For example, you can change from a preset designed for intense gaming, featuring low latency and high performance, to a default setting appropriate for regular home use. If you’re an experienced user you have the ability to manually change parameters in the BIOS.
This is really something to mention if you’re relatively new to building gaming PCs. Generally, most current models are user-friendly with a plug-and-play modality, meaning you can simply push the RAM into the designated slot and get started without a lot of extra work.
If overclocking is your thing, it’s easy to find modules today that allow for automatic overclocking, which is great because it eliminates the work required to make BIOS adjustments.
In short, there are a lot of great RAM options for your new gaming PC. We found great options for low-profile systems, laptops that require SODIMM, exciting aesthetic options, and simply RAM that gets the job done.
While all of our selections are great in their own ways, we felt that the DDR4 RAMs in general outweigh their earlier counterparts. If you have the room in your budget and the compatibility, going with the options of faster speed and higher bandwidth will make up for any slight latency issues.
Given that, we felt that the Corsair Vengeance LPX was the best overall choice for a standard DDR4 RAM. The modules were designed with the needs of the high performing gamer in mind. This workhorse is made for automatic overclocking while maintaining stability.
With the variety in speed options you can make some room in your budget, but overall you will find that the cost justifies the great performance. If you have the latest Intel X99 platforms, you’ll experience no trouble with compatibility.
