Upgrading Your DDR Laptop Memory Without Problems

You have probably landed on this page because you need to get up to speed with what DDR notebook memory is or you are bang in the midst of attempting to improve your notebook but stuck exactly what to do. You have probably landed on a page which may help!

A fantastic place to begin is an introduction to DDR notebook memory…

Kinds of DDR notebook memory


DDR stands for Double Data Rate and is an enhanced (quicker) form of SDRAM (Synchronous Dynamic Random Access Memory). Virtually all notebooks sold today in addition to those marketed since circa 2002 utilize a given (newer or older) version of DDR notebook memory. Set it in plain English DDR memory is much faster than normal SDRAM since it can move data on both falling and rising edge of each clock cycle and consequently the ‘dual’ in its own name. There is simply no reason why you should remember that but only note that if you visit DDR SDRAM mentioned everywhere, make certain to appreciate that is the specific same thing as plain vanilla DDR.

So moving on, what sorts of laptop memory do we have?

DDR laptop memory, otherwise called DDR1 (though this isn’t an official name instead referred to as just DDR) or DDR SDRAM is the oldest and slowest.

DDR3 is presently the most recent type of laptop DDR memory and is yet a additional growth of DDR2 boosting speed a more notch. It can be located in capacities up to 4GB (per module) and speeds up to 1600MHz (effective).

Fortunately, the industry appears to prefer the shorthand naming convention.

How do the aforementioned types relate to your laptop?

Which sort of DDR laptop memory do I need?

When upgrading laptop memory you want to identify which sort of DDR memory is used thus supported by your laptop. Failing to do this will indicate a failed upgrade for a very simple reason – all versions of DDR are incompatible with one another and use another sort of slot connector, which differs in the amount of pins (and a lot of other technical aspects).

Speaking of memory slots we will need to introduce memory modules. In contrast to desktops your laptop uses a more compact form of memory slot that consumes less space. Because of this, the memory modules used in laptops are smaller too. You might or might not have heard the expression DIMM (Dual In-line Memory Module) before, particularly in the event that you’ve upgraded your desktop computer (now is a excellent time to jog your memory!) . The name isn’t very important except what this means in practise, namely you can’t install a DIMM in a SO-DIMM memory slot and vice versa. DIMM’s are considerably longer than SO-DIMM’s and aren’t designed for use in laptops. Before going further we should also point out that you may stumble upon SO-DIMM written as SODIMM – this is the specific same thing!

how to upgrade

So merely to recap, we know various kinds of DDR, that various versions of DDR don’t mix and also that we can’t use any DIMM’s lying around the house and/or office (should you have any) in our laptop. Next we will need to conclude precisely which sort of DDR memory we are in need of, specifically what’s going to work in our laptop.

A fantastic indicator what type is perfect for you is your laptop’s age. Laptops produced in the years 2001-2003 will be quite likely be DDR based. Armed with this info you’ll know whether to purchase a DDR SODIMM, DDR2 SODIMM or perhaps a DDR3 SODIMM.

Another aspect you will need to evaluate is the memory controller in your laptop. A very simple process to obtain this out (and be told what sort of DDR is suitable for us) is to run some diagnostics software on the machine. The truth be told, there are tens and tens of alternative approaches to approach this. We recommend downloading and running CPU-Z, it is completely free – download CPU-Z here. This simple yet beneficial application will amongst other facets tell us exactly what memory our notebook uses so supports (remember what we said about not mixing kinds of DDR?) . Click the ‘Memory’ tab and also the ‘SPD’ tab. There you will discover the name DDR, DDR2 or DDR3 followed by different odd looking numbers like the memory frequency and various timings. You’ll also discover the name that matches the sub-type of DDR laptop memory used by your laptop – this will be something along the lines of PC2-5300, PC3200, PC3-8500 etc.. Simply piece the two together (i.e. DDR2 PC2-5300, DDR PC2100, DDR3 PC8-8500) and you will know what to purchase and therefore install.

We know what memory we are in need of, a logical next step is therefore to determine where to purchase it!

In this day and age once the web overwhelms in options from where to purchase laptop memory it’s not possible to supply a definitive collection of safe online outlets. For this sole reason we won’t journey down this route but instead recommend you purchase your laptop memory upgrade from names which have been in operation for years and are thus dependable. In terms of the make of memory you might wind up buying from one of these stores, do pay note if it has a lifetime manufacturer warranty – almost always it will, but should this not be the case then let this cause you to think twice about clicking the purchase button!

The fantastic thing is that regardless which sort of DDR laptop memory your laptop uses, installation is very much the exact same for either. The only key difference (except of course for installing each in a compatible memory slot) is that in the example of DDR2 and DDR3 laptops, it’s good practise to install memory in pairs (i.e. two modules at a time). Doing this enables the so called dual channel mode on suitable laptops, which triggers a performance boost (enhanced memory throughput). For those who have such a laptop then just make sure you order two modules instead of one.

For this reason most of you are going to want to turn your laptop upside down. In other cases your memory may be below the keyboard or touchpad (let’s guess…Lenovo/IBM Thinkpad perhaps?) . In either case getting inside (lifting the memory bay cover or similar) will be easy providing you have the ideal Philips screwdriver. Sometimes you might want to speak with your laptop’s manual (these almost always lets you know where the memory is installed) for clues what screws need unscrewing (usually 2-3). It’s important you earth yourself throughout the whole process as electro-static impulses can damage laptop memory. Either purchase a cheap anti-static wristband or remember to touch something made from metal like a table leg regularly.

Once inside, simply remove the current memory module by pulling the latches at either ends in an outwards direction (should you will need to free up space) in which case the present module will pop up. If you don’t need to free up space and just wish to insert the new module, align the latch on the slot and module correctly and then insert the module at about an angle of 45 degrees.

Then turn on your laptop and your memory should register all and well. If your laptop fails to turn on then one or more memory modules may not be inserted properly, or possibly (rarely) faulty.

You should go with laptop whose inbuilt memory is above 4GB this is basic and you can check out the best laptop in india under 35000 on our website. Laptop with 8 GB ram is excellent.
