RAM SS vs DS: Which is Better For Windows 11?


RAM stands for “Random Access Memory.” While it may seem complicated, it’s among the most basic components of computers. RAM seems to be the ultra-quick but transitory computer storage capacity, which a computer requires now or soon. RAM is a storage purpose that vanishes whenever the current is shut off. It’s extremely fast, making it excellent for items your system is working actively, including running different apps and the information they operate on.

Now, there are three different kinds of ranks for RAMs. The most popular ones are SS (single-sided) and DS (Double-sided). These two RAM options are similar yet different in performance, which can def a vital role in choosing your system. Today we’re going to talk about RAM SS vs. DS.


SS in RAM stands for single-sided Random Access Memory. Only 64 bits can be stored in this sort of RAM at a certain period. All eight black chips will be found solely on a single end of a RAM card. Each of the chips has an eight-bit capacity. Just a few of the RAM chips have eight chips on both sides. However, it only retains 64 bits instead of 128. This happens because each of the 16 chips has a capability of four bits rather than eight bits.


Double-sided is abbreviated as DRAM. Both of the sides of RAM have chips in this case. On one side, there are 8 chips, while on the other side, there’s another set of 8 chips. As a result, they have a total of 128-bit capacity for speed.

Is there any performance difference between SS and DS in RAM?

From the SS and DS RAM definition, you can already guess that there must be performance differences. Otherwise, there wouldn’t be different RAMs. If you pay close attention to the facts and the technical details, it’s crystal clear that these are different. The basic and the foremost difference is the number of ranks. While the SS has a single rank and DS has a double rank which makes sense by the names of these two kinds of RAMs. Have you thought about what it’d be like to get a clear idea about RAM SS vs. DS?

What’s a Memory Rank?

While storing or analyzing information, each data bus comprises a collection of DRAM processors that are addressed. Such chips, also known as ranks, can be inserted solely on a single or on both flanks of a storage drive. A single rank arrangement is a storage unit that is sixty-four bits large, which is seventy-two bits for ECC memory and has eight extra bits enabling correcting errors. In other terms, this is a single memory branch or collection of storage chips. Because dual-rank modules have two data blocks, they will be one hundred and twenty-eight bits wide. Accordingly, there are also octa rank and quad rank modules, which have four to eight sixty-four bit wide blocks of data. These are typically used for increased memory units with huge storage capacities per module.

Rank’s number can indicate the RAM device’s internal storage. Yet, it is mostly reliant on the technology of the memory stick’s processors and the DDR version. Since most IC chips can only accommodate one GB of storage, many modern DDR4 sixteen GB drives are dual-sided. For example, Crucial’s greater capacity RevB chips, on the other hand, allow for up to sixteen GB of memory in a single-sided RAM. Dual rank and quad rank thirty-two GB memory chips are viable because one single rank eight GB or even sixteen GB module can be used. There is currently no DDR4 thirty-two GB single ranking storage module available. However, as technology progresses, we might see more of those.

Performances Differences

There are many categories where SS and DS differ from each other. These categories will tell you which RAM is better than the other one. Let’s take a look at the RAM SS vs. DS.


SS RAM is also known as single-rank RAM, referring to the fact that it has only one rank. Dual rank RAM is the most common type of double-sided RAM. In SS RAM, quad and octal rank storage are also available. Multi-rank components are used to increase the module’s density. Another advantage of numerous ranks is holding more accessible memory, enhancing efficiency in some instances.

The Strain on the Program Memory

However, having more ranks increases the strain on the program memory, so each control system restricts the total of levels it can manage and how quickly it can manage them.


The memory controller looks to provide superior efficiency with a dual-sided than a single-sided RAM for such a restricted memory capacity. Still, users report that DS modules cannot be clocked as high. Just that the memory controller can’t take it as well, when it comes to your memory, there is no such thing as greater and worse if you’re not comparing it with anything else. Dual-sided modules may provide a minor speed boost every and then, but single-sided modules should work with a wider range of memory processors.


As we all agree that there’s less pressure on that system memory, SS DIMMs could likely be paced quicker than the DS DIMM ones.

Storage chips

Larger storage chips are used in single-layer DIMMs with the very storage as the double-sided DIMMs. Such larger chips could be the result of a more recent production technique. They could be quicker and have reduced voltage, allowing devices to be synchronized faster.

Bits capacity

Single-sided RAM usually has 64 bits capacity while Double-sided RAM has 128 bits capacity


Single-sided RAM is also known as Rank 1 RAM, and Double-sided RAM is known as Rank 2 RAM.

Overlocking power

Single-sided RAM can overclock higher than double-sided, while Double-sided RAM sometimes overclocks lesser than SS RAM.


Single-sided RAM has eight chips on it and rarely sixteen chips. A Double-sided RAM has sixteen chips.

Compatibility with Memory Controllers

Single-sided RAM can work efficiently and steadily with a Memory Controller, while Double-sided RAM can get stressful with memory controllers.


Single-sided RAMs have “1R” marked on them, and the Double-sided RAMs have “2R” marked.

Switching banks

Single-sided RAMs do not need to switch banks, but Double-sided RAMs need to switch banks.


Generally, Single-Sided Memory is speedier than Dual-Sided Memory. To put it another way, whenever a system enters Single-sided storage, it seems to only go outside the rail once, whereas Dual-sided Storage requires two trips around the rail. Nevertheless, some computers function best with multiple rank memory because of internal memory processors. This one is particularly true in the case of server memory that uses LRDIMMs.


As the storage controller only needs to go through all of the memory for retrieving only once, SS provides faster access to the data for just about any application. Although dual-ranking can provide you with more storage space, most games these days do not even use quite as much. As a result, choosing a SS setup will provide you with the optimum gaming experience.


In most circumstances, Dual Sided Memory can be used alongside Single-Sided RAM. In certain cases, while using a big quantity of recollection, like16GB, the motherboards demand the usage of a combination of both Single and Dual sided RAM.


When comparing both Single and Dual-Sided RAM at the same speeds, the latter has a little advantage – varying from three to five percent.

Cycles of renewal

Masking and parallelizing refreshing cycles normally increase productivity for CPU-intensive programs by reducing memory responsiveness, but this is not the case with single-sided.


The latency produced by the program memory running across several levels instead of simply one, including single-sided RAM, may impact some programs.

Generating heat

Single Rank, DIMMs emit less temperature and are more reliable than the Dual Rank DIMMs due to the fact that they contain half the number of chips. It’s also one of the reasons why overclockers favor them.

Your computer will be able to utilize it all at once with SS RAM. This allows you to see every one of its memories in one go. These same chips in DS RAM, on the other hand, are split into two different banks. Just one part of it can be seen at once by the computer, not both. Your system may not have recourse to the opposite end of this bank while analyzing the very first part of this bank. Whenever the machine reads the other half of the data, the exact same thing happens. SS RAMs are superior to DS RAMs. PINs 33 and 45 are used on the motherboard so that the double-sided storage can work properly.

Owing to the reduced performance of DS RAM, elevated devices might not get it, although the variation is minor. To enhance the effectiveness of the computer, you’ll also choose an appropriate memory size, CL, and other essentiallarge factors.


If you’ll be utilizing your computer regularly, such as at school or the workplace, it’s best to go with the lowest of the two options. Because the differences between SS and DS RAM are minor, they can be overlooked. Rams with only one set of chips are known as single-sided RAMs. This cuts down the amount of time it takes the controller to finish a job. When you utilize your computer for demanding workloads, a SS RAM seems safer than a DS RAM. Or else, you can choose the less expensive RAM. Once the computer is solely used for everyday duties, changing to different kinds of RAM has little influence on productivity. Hopefully, you learned a lot about RAM SS vs. DS from this article.
