Highlights You Want To Remember An Upgrade Without Stress SODIMM Laptop!

Once your laptop loses glamor, it is often the cause is lack of system memory. 

What is a SODIMM laptop?

The laptop SODIMM is the little laptop memory module outline dual speed line. Fortunately, a SODIMM is quite small and is the name given to the PCB (Printed Circuit Board) in the modern laptop memory is sold.

Therefore, whenever you come across an upgrade laptop memory is very likely to be a SODIMM notebook of some sort. Does this mean all SODIMM laptop are identical? Laptop SODIMM differ depending on the type of memory they have. For example, they are 144pin, slightly newer DDR and DDR2 SDRAM SODIMM 200-pin SODIMMs are more whereas currently last 204pin SODIMM DDR3 are. Its physical dimensions also vary but slightly.

The main thing to remember is that different types of laptop SODIMM can not be mixed on the same laptop. For example, if your laptop uses DDR3 memory so do not even try to install a DDR2 SODIMM there.
 
Laptop SODIMM compatibility

While it is impossible to mix and match SDRAM, DDR, DDR2 or DDR3 SODIMM (any combination) together is usually fine to mix and match the same types SODIMM assembly, even if the brand of memory is different. For example, say you have a laptop DDR2 comes with a single DDR2 SODIMM. Its capacity is almost irrelevant, but suppose your 2GB. Now you want to upgrade to 4GB, but the laptop DDR2 memory upgrade is purchased a different brand is currently installed (ie, Samsung Vs Hynix). Does this work? For example, if the current 2 GB of RAM is PC2-5300 (667MHz effective) variety, you want to make sure your new laptop SODIMM DDR2 PC2-5300 is at least, if not the memory controller into your computer mobile will be forced to operate both SODIMM at a lower speed (ie slower) SODIMM. Extrapolating further, PC2-5300 and PC2-6400 DDR SODIMM modules will work together while the 667 MHz and not 800 MHz (effective).

So why mixing different brands of portable single SODIMM work in 99% of cases. The long answer is that, some portable memory brands smaller still not 100% after the JDEC (organization working memory specifications) specification, other BIOS (basic input of the system) is often found in laptops are not without bugs. Update SODIMM laptop - important recommendations to consider before buying

We have set up the following list of aspects you should look for when you want to buy a laptop SODIMM. For peace of mind, we recommend:

A) Whenever possible, try and buy the same brand of memory for what you have already installed or purchase an upgrade laptop memory of a respected brand

B) Buy the same memory speed to what is currently installed, or installed PC2-5300, PC2-5300 SODIMM then buy a laptop as it is very rare that the memory controller your laptop can operate in a specification of larger memory, and even if it can, the slower memory currently installed will prevent this (unless you change all new faster SODIMM specification)

C) If financially possible to do, and always try to buy the same capacity SODIMM for what you have installed (see below why)

D) If you update the portable memory that you intend to buy are not lifetime warranty, so it's best to avoid it completely, the memory respected brands offer lifetime warranties because " they believe in their products, so you should (for peace mind)

E) Just buy a laptop SODIMM integrate performance SODIMM laptop instead. This will feature faster memory timings, providing a modest increase in performance. To make them work in these times, however, all installed memory modules must meet this specification. As your laptop currently installed probably sometimes a little slower, the BIOS of your laptop will use them, and not the fastest time.

Dual channel laptop SODIMM fashion

Most modern laptops support what is known as dual channel mode. In practice, this means two SODIMM laptop are available in parallel for best performance (bandwidth).

When the dual channel mode was introduced (in DDR memory for notebook computers) operating only in what is known as the synchronous mode. Latest user support DDR2 and DDR3 Laptop Memory for both synchronous and asynchronous.

Synchronous mode only works when two identical SODIMM installed. The asynchronous mode, on the other hand only works when two identical SODIMM are not installed, not identical, in that they vary in capacity, for example 1x 1GB and 3GB 1x2gb =.

Whether you have an old laptop DDR2 DDR memory or newer DDR3 or laptop, and always try to install SODIMMs of the same capacity. This will ensure your submission (where your laptop supports dual channel mode) operates in synchronous mode.

If you have a DDR2 or newer laptop supports dual channel mode and install a SODIMM capacity of non-identical, this will force asynchronously. In such a situation, only a portion of your memory will operate in dual channel mode, the other party will run in single channel mode.
