Once your laptop loses OMF, it is most likely due to insufficient system memory. You may have heard that modern laptop memory upgrades come in the form of SODIMM laptops, but what are they, and perhaps most importantly how do you buy one for your laptop? To avoid confusion, let’s think about the important things you should know before clicking the order button!

What is a SODIMM laptop?

Laptop SODIMM is an abbreviation for the small inline dual memory module for a laptop. Aren’t you thinking enough? Fortunately, SODIMM is small and is the name given to the PCB (printed circuit board) that sells modern laptop memory.


Consequently, whenever you find a laptop memory upgrade, a laptop for SketchUp pro some type of laptop is likely SODIMM. Does this mean that all portable SODIMMs are the same? Unfortunately not, but luckily it’s not as complicated as it sounds.


A SODIMM laptop varies depending on the type of memory it has. For example, the old SODIMM SDRAM is 144 threads, the newer DDR and DDR2 SODIMM is 200 threads, while the newer DDR3 SODIMM is currently 204 threads. Its physical size also varies, but sometimes a little.


The important thing to remember is that different types of SODIMM laptops cannot be combined into different laptops. For example, there is no point in installing DDR2 SODIMMs if your laptop uses DDR3 memory. Not only the number of pins are different, but also the pin configuration, operating voltage, timing, and address.


Does this mean that updating is a better burden for professionals? not!


Compatibility with SODIMM laptops


Although it is impossible to mix and match SDRAM, DDR, DDR2, or DDR3 SODIMM (any combination), the same type of SODI is generally suitable for mixing and matching MM, even if the memory brand is different. Let’s put it in perspective.


For example, let’s say you have a DDR2 laptop that comes with the same DDR2 SODIMM. Its capacity is completely irrelevant but let’s say 2 GB. Now you want to upgrade to 4GB but the memory upgrade of the DDR2 laptop you purchased is from a different brand than the one currently installed (eg Samsung vs Hynix). will you work? Yes in 99% of cases! As you can see, branding is mostly not a problem, but what’s relevant is that both modules are DDR2, so follow the DDR2 SODIMM spec.


This is acceptable even if memory times vary between units (unless you want to run every ounce you can get). The only aspect you should pay attention to is the speed of the memory. For example, if your current 2GB of RAM is a PC2-5300 (667MHz efficiently), make sure your new DDR2 SODIMM laptop is at least a PC2-5300 as well, otherwise, you’ll have to run a memory controller in the laptop. Both SODIMMs are low-speed (i.e. slow) SODIMMs. To go further, the PC2-5300 and PC2-6400 DDR SODIMMs will work together at 667 MHz, not 800 MHz (effective).


So why do SODIMMs from different brands only work in 99 cases? The short answer is inconsistent. The long answer is as follows: some lower brands of laptop memory don’t always follow the JDEC 100 definition (the organization that develops the memory specification). Other times, the BIOS (base entry) systems in laptops are not bug-free The net result is a laptop that will constantly beep when turned on when a black screen is displayed.


Is there any way to upgrade without potentially reducing such issues and performance? Nothing is a 100% guarantee that you will avoid SODIMM laptop incompatibility issues, after all, you are the one clicking the order button, but as long as you stick to a few important recommendations, we are sure you will keep smiling at all times.


SODIMM Upgrade for Laptop: Important Recommendations to Consider Before Purchasing


We’ve compiled a list of things to look for when looking for a SODIMM laptop. For maximum peace of mind, we recommend that you:


a) Where possible, try to buy the same brand of memory that you have already installed or buy a laptop memory upgrade from a well-known brand


B) Buy at the same speed as the memory is currently installed, for example, if PC2-5300 is installed then buy a PC2-5300 SODIMM laptop as it is very rare for a laptop memory controller to work with more memory details. , And even if it’s possible, the slow memory currently installed will stop it (unless you convert all SODIMMs to newer, faster ones).


C) Wherever financially possible, always try to buy SODIMMs in the same capacity that you currently have installed (see reason below)


d) If the laptop memory upgrade you are planning to purchase does not come with a lifetime warranty, it is best to avoid it altogether, reputable memory brands offer a lifetime warranty because they Believe in the product, so you (for peace of mind)


e) Buy only traditional laptop SODIMMs instead of high-performance portable SODIMMs. The latter will offer faster memory times, which promotes modest performance. But for these modules to work at these times, all installed memory modules must meet these requirements. Because laptops currently installed will most likely show slower times, your laptop’s BIOS will use them, not faster.


Dual-channel SODIMM mode for laptops.


The majority of modern laptops support this, which is called dual-channel mode. In practice, this means that two SODIMMs of the laptop can be accessed (bandwidth) to improve performance.


When the dual-channel mode was introduced (in laptops with DDR memory), it only worked in what is called synchronous mode. Sophisticated laptops with DDR2 and DDR3 memory support both synchronous and contrast mode.


Sync mode only works when two identical SODIMMs are installed. A similar case extends to two modules of the same capacity, for example, 2 x 512 MB = 1 GB.


Unstable mode, on the other hand, only works when two unmatched SODIMMs are installed, and they are not identical in that they differ in incapacities, such as 1x 1 GB and 1 x 2 GB = 3 GB.


Regardless of whether you have a DDR laptop or a new DDR2 or DDR3 laptop, always try to install SODIMM with the same capabilities. This will ensure that the memory (as the laptop supports dual channel mode) works in sync mode.


If you have a DDR2 or later laptop that supports dual channel mode and installs SODIMMs with unmatched capabilities, this will force asynchronous mode. In this case, only one part of the memory will work in dual channel mode, and the other part will work in single-channel mode.
