SODIMM Memory Frequency, Capacity, Timings - How to Balance Your Next Laptop Memory Upgrade

Your laptop grinds under the strain of software memory requirements forcing you to purchase a laptop memory upgrade. The question is, how do you go about buying an upgrade that reaps the most benefits? We'll take a look at this below.

SODIMM Memory Frequency

Regardless of the type of memory, be it SDRAM, DDR, DDR2, DDR3 etc. memory frequency pays a pivotal role in its performance. You see, frequency influences the speed at which bytes can be read and written to and from a SODIMM memory module.

The faster the frequency of a SODIMM memory module, the greater the bandwidth available to your system, thus ultimately the software you run. Some software benefits more than others when more bandwidth is available, nevertheless it's generally a good idea to have more of it if possible.

Of course depending on your model of laptop, it might not be possible to make use of higher frequency SODIMM memory modules. The underpinning for this is simple, while a laptop supporting for example PC2-4200 DDR2 SODIMM memory that runs at 533MHz effective can have a higher rated SODIMM memory module of the same type but higher grade installed (i.e. PC2-5300 DDR2 running at 667MHz), the net result will still be memory that runs at a maximum of 533MHz. This is true unless of course the memory controller in that laptop supports the frequency of the faster memory. Normally laptop manufacturers already install the fastest grade of memory during production..

Should you conclude that your laptop does support faster SODIMM memory modules, it may just be worth upgrading all the installed memory to whatever highest grade is supported. Memory frequency is the number one contributor to memory bandwidth therefore by in large performance. Do note how we wrote "all" the installed memory. You see, for your laptop to run at the faster memory frequency, all installed SODIMM memory must meet this specification thus be of the same grade. If your laptop has two SODIMM memory slots (this is the norm) then in practise both SODIMM memory modules must be identical. For example, in a DDR2 memory based laptop this might be PC2-6400, in a DDR laptop PC3200, in a SDRAM laptop PC133 or any other available combination. Simply follow this line of thought and you'll be okay.

SODIMM Memory Capacity

The amount of memory you have installed in your laptop is what generally speaking ultimately defines how smooth software runs. Consequently, while memory frequency is a key factor to SODIMM memory performance, the capacity of memory installed is fundamental for overall system performance.

How much memory you need is dependent on what software you run. Unfortunately, there's no golden rule that magically works for each and every application out there. Fortunately however there's an old principle that lends a helping hand: more memory always helps. Essentially what this translates to in practise is this: install more memory than you need as this way you're far less likely to run into slowdowns, providing of course the slowdowns are the result of low system memory and not, per se, the processor, graphics card, storage device etc.

Does this sound too good to be true? Regrettably yes, for three reasons. Firstly, buying too much laptop memory will likely aid laptop performance at the cost of upsetting your wallet. Secondly, in an ideal world all laptops, be them new or old, would support the currently maximum capacity of available SODIMM memory modules. Obviously the world isn't an ideal place and thus you can only upgrade to the maximum capacity supported by your laptop's memory controller. Thirdly, if you're running a 32bit Operating System on a laptop supporting 4GB or more of memory then just keep in mind that even though the memory will work, applications will not use the full 4GB. This is a limitation of 32bit addressing, only some of this namespace is available to system memory, the rest must be used for addressing other types of memory within your laptop, for example that of the graphics card. To overcome this on laptops that support it, upgrade to a 64bit Operating System.

Starting to sound slightly complicated? Let's break this down into simple English. What you should deduct from this is as follows: buy as much memory as your wallet and laptop allows but consider the limitations of 32bit Operating Systems. If you plan to upgrade to 4GB or more of memory and have a newer laptop then upgrade its Operating System to a 64bit version. If your laptop supports 4GB but only 32bit Operating Systems then just keep in mind that the maximum your applications will likely see visible thus use is around 3.25-3.5GB.

SODIMM Memory Timings

Computer memory feature what's known as timings. These are numerical values which represent delays in how a SODIMM memory module operates. The actual values vary depending on the type of memory (i.e. DDR2) and whether the given SODIMM memory module is mainstream or a performance part. Such delays control all the types of commands that get executed when your computer issues a read, write or copy command. Such timings are stored on each SODIMM memory module in what's known as a SPD (Serial Presence Detect) chip, located on the same PCB (Printed Circuit Board) as the memory chips.

Because memory timings are ultimately delays then one might think it's logical to assume that lower timings are better. This can be answered as true but only to an extent. You see, there is only so much that these timings can be lowered, even if a SODIMM memory module has been binned as a performance part. This is due to synchronisation issues. Memory timings control how slow or how fast a given operation is processed by a SODIMM memory module. If it's set too fast then the outcome may be unstable operation. At the very least this will cause erroneous software behaviour, or if you're less fortunate a system halt.

Since enhanced memory timings can only contribute so much to real-world system performance (circa 5% real-world performance boost), it's really a case of deciding whether you believe the added speed boost (i.e. slightly more memory bandwidth, somewhat lower memory access latency) is enough to warrant the price premium. Various tests over the years suggest no, even if you install "performance" SODIMM memory, you're not likely to feel the difference in any type of software but benchmarks.

Conclusion

There are some important facts to recall from the above. First and foremost memory frequency plays a pivotal role in memory performance, otherwise defined at the speed at which memory read, write and thus copy commands get processed. The higher the memory bandwidth, the more it indirectly influences overall system performance. Secondly, memory capacity is what directly affects the overall speed of your laptop by having a direct influence on computer performance. The more memory you have installed, the far less likely you are to run into slowdowns caused by insufficient memory resources available to the Operating System and other software. Thirdly, memory timings act as an icing on the cake (for a better term) to both memory frequency and capacity.

The above is the theory, but what should you do when getting ready to buy your laptop memory upgrade? Always get the highest frequency of SODIMM memory your laptop supports by determining the highest speed grade supported by its memory controller. Wherever your wallet permits, also try and upgrade to a healthy amount of memory, above what you're bound to currently use thus leaving yourself some headroom. Do however remember that your laptop's memory controller also limits the maximum capacity you can upgrade to. Finally, where feasible (something you will have to deduce yourself), choose a SODIMM memory module(s) with faster (lower) timings - if performance parts aren't available then the most you will lose is about 5% overall system performance.

Why laptop Computer memory matters?

The topic of laptop memory size is by no means new. What is more distinct however is that most people hear advice such as "more memory is always better" and automatically conclude that this stateMent is true whatever the use of your Computer. The real truth behind this is that while such advice is generally correct, it is best understood once one appreciates the background facts. All laptop Computers make use of a certain Operating System - Microsoft Windows is by far the most popular (Windows 95, 98, Me, 2000, XP, Vista or 7 etc.). This is the software that both interacts and manages two aspects: a) the hardware and other software used on it and b) the user (hardware).

An Operating System must load its own components into memory when it starts. In effect, a large chunk of its footprint gets copied into physical memory within your notebook computer, this in turn found on the memory modules inside your laptop's chassis. To add to this, any additional software that is necessary to run your laptop computer for the purposes you use it is also loaded. This usually means any device drivers and third Party software. Ideally the Operating System attempts to allocate most or all the above in physical memory. If there is an insufficient amount of such memory, the Operating System will imitate it on your laptop's storage medium. The latter will in most cases mean a hard drive or solid state drive (in newer laptops). The term given to describe it is virtual memory.

Since both a hard drive and solid state drive are considerably slower than notebook computer memory, the effect of this is that performance will be degraded. The net outcome of this is that it may take longer for software programs to load, to run, to shutdown, and to switch between (multi-task) etc. The more of these software programs run in such circumstances, the more the performance will suffer.

How much laptop computer memory is enough?

A cure to the above problem are laptop memory upgrades. This will expand the total amount of physical memory in your laptop computer and either reduce or completely eliminate the slowdown associated with insufficient physical memory. How much laptop computer memory is enough is subject to two different aspects: a) what types of software do you use on your laptop computer and b) how much laptop memory does your laptop computer support.

To answer part "A" you need to ask yourself what software you use. For example, you may simply use it for Internet browsing, word processing, the odd game. Alternatively you may use it professionally for graphics work or audio or video editing. Furthermore you may be an avid gamer. Each of these scenarios reflects a different optimum amount of laptop computer memory. For simple Internet browsing and similar 2GB will in most cases be enough. If however you are a professional doing graphics/audio or video work then anything between 4-8GB will probably suit you best. If on the other hand you are a gamer, 4GB or more is likely what you should be aiming for.

To answer Part "B" is a little trickier because in order to determine how much laptop computer memory your laptop supports, you need to either look into the user manual (not always possible and exhaustive) or determine the memory controller it uses. Either method works with the latter being more for the hardcore computer user. Luckily, there are tools online that will scan your laptop computer and tell you this information without any or much technical awareness on your part. You can find these tools by simply searching online, or optionally visiting my website. Whatever the outcome from part "A" or part "B" you should always opt for the most optimum laptop memory upgrades, both for your laptop computer and the tasks you use it for. As a result you will guarantee a smoother user experience.

In Summary

Be sure to extract the most important traits of the above information. Both the Operating System and any additional software used on your laptop computer are loaded into physical memory. Should your laptop computer not have enough of physical memory for the purposes for which you use it, the Operating System will simulate it in what is described as virtual memory. Unfortunately, the latter is considerably slower than physical memory and thus performance is degraded.

A well chosen laptop memory upgrade is a solution to the above. How large it should be is determined via a) what you use your laptop computer for and b) how much physical memory your laptop computer supports. This information can be rendered via asking yourself the first question, and looking in the user manual or using an online scanner for the second question.

Once you determine and opt for suitable laptop memory upgrades, you will witness a Faster performing laptop!

What is the Best Laptop Memory (RAM)

To buy a new laptop with the right amount and speed of memory that will suite your needs, you will need to consider two factors. The first and most important is the amount of memory the laptop has installed. This will be measured in Gigabytes (GBs), where a typical> laptop will have anywhere from 1 GB to GHz 4GBs of memory.

If you only plan to user your laptop for office programs or surfing the internet, 1 GB of RAM will be enough to ensure your laptop is Fast and smooth. If however you want to multitask and use the programs above but also use instant messaging programs such as Skype or MSN messenger while listening to music or Watching movies, you should be looking at 2GBs of RAM to make sure your laptop will run smoothly.

Those of you that will want to play games or use intensive programs like video or graphical editing might want to consider 3-GHz 4GBs even though you might be able to get away with 2GBs. If you do go with 2GBs you might need to upgrade to more memory later on as new programs will use moreRAM as technology advances.

You can get more than GHz 4GBs of memory, but you will struggle to use all of it at any one time so buying more than GHz 4GBs will be a waste of money. Most manufacturers try to sell you more memory then you will ever use to try and get some more money out of you. Always remember that adding more memory only speeds up your laptop to the point where the programs you run have enough memory to use. Once this point is reached, adding additional memory will have no effect on performance.
