Your laptop grinds under the strain of software memory requirements forcing you to purchase a laptop memory upgrade. The interrogate 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
Ddr2 Ddr3
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 ready to your system, thus finally 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 procedure depending on your model of laptop, it might not be potential 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 sufficient 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 ensue will still be memory that runs at a maximum of 533Mhz. This is true unless of procedure the memory controller in that laptop supports the frequency of the faster memory. Regularly laptop manufacturers already setup the fastest grade of memory during production..
Should you halt that your laptop does support faster Sodimm memory modules, it may just be worth upgrading all the installed memory to anything highest grade is supported. Memory frequency is the amount 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 ready combination. Plainly ensue this line of conception and you'll be okay.
Sodimm Memory Capacity
The amount of memory you have installed in your laptop is what generally speaking finally defines how plane software runs. Consequently, while memory frequency is a key factor to Sodimm memory performance, the capacity of memory installed is basic for allinclusive principles 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 any way there's an old principle that lends a helping hand: more memory always helps. Essentially what this translates to in practise is this: setup more memory than you need as this way you're far less likely to run into slowdowns, providing of procedure the slowdowns are the ensue of low principles memory and not, per se, the processor, graphics card, storehouse gadget etc.
Does this sound too good to be true? Regrettably yes, for three reasons. Firstly, buying too much laptop memory will likely aid laptop doing 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 ready 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 principles 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 ready to principles 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 reconsider 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 principles 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 descriptive thus use is colse to 3.25-3.5Gb.
Sodimm Memory Timings
Computer memory feature what's known as timings. These are numerical values which laid out delays in how a Sodimm memory module operates. The actual values vary depending on the type of memory (i.e. Ddr2) and either the given Sodimm memory module is mainstream or a doing 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, placed on the same Pcb (Printed Circuit Board) as the memory chips.
Because memory timings are finally 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 doing part. This is due to synchronisation issues. Memory timings control how slow or how fast a given doing 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 principles halt.
Since enhanced memory timings can only conduce so much to real-world principles doing (circa 5% real-world doing boost), it's actually a case of choosing either you believe the added speed boost (i.e. Slightly more memory bandwidth, somewhat lower memory entrance latency) is adequate to guarantee the price premium. Various tests over the years suggest no, even if you setup "performance" Sodimm memory, you're not likely to feel the divergence in any type of software but benchmarks.
Conclusion
There are some important facts to recall from the above. First and important 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 allinclusive principles performance. Secondly, memory capacity is what directly affects the allinclusive 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 ready to the Operating principles 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 salutary amount of memory, above what you're bound to currently use thus leaving yourself some headroom. Do any way 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), pick a Sodimm memory module(s) with faster (lower) timings - if doing parts aren't ready then the most you will lose is about 5% allinclusive principles performance.
