You’ve almost certainly landed on this web page due to the fact you both want to get up to velocity with what DDR notebook memory is or you’re bang in the middle of striving to improve your laptop but trapped what to do. Well you know what? You have almost certainly landed on a webpage that can assist!
A very good place to start is an introduction to DDR laptop computer memory…
Kinds of DDR laptop computer memory
DDR stands for Double Data Rate and is an increased (more quickly) form of SDRAM (Synchronous Dynamic Random Entry Memory). Nearly all laptops sold right now as properly as these sold because circa 2002 use a given (older or newer) model of DDR notebook memory. Put it in plain English DDR memory is faster than regular SDRAM since it can transfer information on each the slipping and increasing edge of every single clock cycle and that’s why the ‘double’ in its identify. There is absolutely no purpose you must bear in mind this but just notice that if you at any time see DDR SDRAM pointed out wherever, be confident to value this is the actual very same point as basic vanilla DDR.
So moving on, what varieties of notebook memory do we have?
DDR laptop computer memory, or else identified as DDR1 (even though this isn’t really an official name rather referred to as just DDR) or DDR SDRAM is the oldest and slowest. laptop price is predominantly obtainable in capacities up to 1GB (per module) and at speeds of up to 400MHz (efficient).
DDR2 is an evolution to DDR with some inner enhancements to improve efficiency and normally available in capacities up to 2GB (for every module) and speeds up to 1066MHz (successful).
DDR3 is presently the most current kind of laptop computer DDR memory and is however a even more evolution of DDR2 boosting speed a more notch. It can be found in capacities up to 4GB (for each module) and speeds up to 1600MHz (successful).
Recognize that we could have explained DDR2 SDRAM just as DDR3 SDRAM. For simplicity sake, adhere to remembering that there is DDR, DDR2 and DDR3 due to the fact fairly frankly this is what you may experience most! Luckily, the business looks to choose the shorthand naming conference.
You may possibly also want to discover far more about DDR, DDR2 and DDR3 notebook memory.
How do the over types relate to your laptop? This we are going to take a look at subsequent!
What sort of DDR laptop memory do I require?
When upgrading notebook memory you need to recognize what type of DDR memory is used therefore supported by your laptop. Failing to do this will suggest a failed update for a really simple explanation – all versions of DDR are incompatible with every single other and use a various kind of slot connector, which differs in the quantity of pins (and numerous other complex factors).
Speaking of memory slots we require to introduce memory modules. In contrast to desktops your laptop computer utilizes a more compact form of memory slot that consumes significantly less place. As a outcome, the memory modules utilized in laptops are smaller way too. You might or may possibly not have listened to the expression DIMM (Dual In-line Memory Module) ahead of, specifically if you have upgraded your desktop computer (now is a excellent time to jog your memory!). Laptops use SO-DIMM’s – simply append ‘Small Outline’ to a DIMM. The name isn’t really extremely important apart from what this implies in practise, particularly you are not able to put in a DIMM in a SO-DIMM memory slot and vice versa. DIMM’s are considerably lengthier than SO-DIMM’s and are not made for use in laptops. Before heading more we should also level out that you may possibly stumble on SO-DIMM written as SODIMM – this is the exact very same point!
So just to recap, we know the various varieties of DDR, that various variations of DDR never combine and also that we can not use any DIMM’s lying about the house and/or business office (need to you have any) in our laptop computer. Next we need to conclude just what sort of DDR memory we require, specifically what will operate in our laptop.
A great indicator what type is proper for you is your laptop’s age. Laptops created in the years 2001-2003 will be very probably be DDR based. Laptops created in the a long time 2004-2007 will be DDR2 and ultimately, laptop created since 2008 will be DDR3 (though some use DDR2). Armed with this data you will know whether to get a DDR SODIMM, DDR2 SODIMM or possibly a DDR3 SODIMM.
A next aspect you require to assess is the memory controller inside of your notebook. A simple technique to discover this out (and be told what type of DDR is correct for us) is to run some diagnostics software program on our machine. The real truth be advised, there are tens and tens of different methods to method this. We recommend downloading and running CPU-Z, it truly is completely free of charge – down load CPU-Z right here. This basic nevertheless useful application will amongst other facets tell us what memory our notebook uses for that reason supports (remember what we stated about not mixing types of DDR?). Simply click on the ‘Memory’ tab and also the ‘SPD’ tab. There you will locate the name DDR, DDR2 or DDR3 followed by various odd hunting quantities these kinds of as the memory frequency and distinct timings. You will also discover the name that corresponds to the sub-variety of DDR laptop memory utilized by your laptop – this will be one thing together the lines of PC2-5300, PC3200, PC3-8500 etc. Simply piece the two with each other (i.e. DDR2 PC2-5300, DDR PC2100, DDR3 PC8-8500) and you may know what to purchase and therefore put in.
Locate out a lot more about DDR, DDR2 and DDR3 SODIMM modules.
We know what memory we require, a sensible following phase is as a result to make a decision exactly where to buy it!
Exactly where to reliably get DDR laptop memory
In this day and age when the World wide web overwhelms in options from the place to buy notebook memory it truly is impossible to supply a definitive checklist of risk-free on the web outlets. For this sole purpose we won’t journey down this route but as an alternative propose you purchase your laptop computer memory improve from names that have been in business for many years and are hence reliable. As for the make of memory you could end up buying from any of these merchants, do spend observe if it arrives with a life span producer warranty – almost usually it will, but need to this not be the scenario then allow this make you feel 2 times about clicking the order button!

How to install DDR laptop memory
The great information is that no matter what sort of DDR laptop computer memory your notebook uses, installation is quite significantly the identical for either. The only important difference (other than of system for installing each in a suitable memory slot) is that in the case of DDR2 and DDR3 laptops, it really is very good practise to install memory in pairs (i.e. two modules at a time). Undertaking so enables the so referred to as dual channel manner on appropriate laptops, which triggers a efficiency improve (enhanced memory throughput). If you have this kind of a laptop computer then just bear in mind to order two modules alternatively of a single.
Most laptops attribute obtain to the memory bay beneath. For this reason most of you will want to switch your laptop computer upside down. Pointless to say, you must change it off very first! In other cases your memory may well be under the keyboard or touchpad (let’s guess….Lenovo/IBM Thinkpad probably?). In possibly scenario acquiring inside (lifting the memory bay include or comparable) will be simple providing you have the appropriate Philips screwdriver. In some situations you may want to check with your laptop’s handbook (these almost often tells you in which the memory is put in) for clues what screws require unscrewing (normally 2-3). It is crucial you earth yourself all through the total process as electro-static impulses can hurt laptop memory. Both purchase a cheap anti-static wristband or bear in mind to contact anything made of metal such as a desk leg regularly. Possibly strategy will preserve your entire body discharged and for that reason risk-free for managing laptop computer memory.
After within, just eliminate the present memory module by pulling the latches at either ends in an outwards route (if you want to totally free up area) in which scenario the current module will pop up. Merely pull it out as soon as free. If you don’t want to totally free up room and just want to insert the new module, align the latch on the slot and module accurately and then insert the module at about an angle of forty five degrees. After the gold plated pins are hidden (inserted) in the memory slot, push down right up until the DDR laptop memory module clicks into location!
Up coming, change on your laptop and your memory need to register all and well. If your laptop fails to flip on then one or a lot more memory modules might not be inserted correctly, or perhaps (rarely) defective.
You could choose to comply with a action by stage laptop memory illustrated installation manual as an alternative.
Upgrading DDR laptop computer memory can be difficult but needn’t be. First and foremost do not overwhelm by yourself with knowledge that will not likely essentially help you when it comes to getting and setting up laptop memory. Of system, there is certainly no stopping you studying up in element about notebook memory upgrades but just bear in mind there are elements you might want to know but don’t want to know. Preserve your self the confusion!
Secondly, set your mindset into conserve manner as you may want to remember that DDR laptop computer memory arrives in various versions (DDR, DDR2, and DDR3) and neither can be blended. What type your notebook makes use of is seriously tied to its age. Thirdly, conserve your desktop memory for your desktop Computer and your laptop memory for your laptop Personal computer, they will not mix, even if your use pliers and Diy is your next identify! SODIMM only!
Fourthly, use a system these kinds of as CPU-Z to screen the kind of memory employed by your laptop, this consists of the type but also product (i.e. PC2100, PC2-4200, PC3-8500 and many others.).
