Nicely hp laptop bangladesh know what? You’ve got almost certainly landed on a page that can aid!
A good area to commence is an introduction to DDR laptop memory…
Types of DDR notebook memory
DDR stands for Double Data Price and is an enhanced (more quickly) form of SDRAM (Synchronous Dynamic Random Accessibility Memory). Practically all laptops bought today as properly as individuals bought given that circa 2002 use a provided (more mature or more recent) variation of DDR laptop memory. Place it in plain English DDR memory is more rapidly than standard SDRAM simply because it can transfer knowledge on each the falling and rising edge of every single clock cycle and consequently the ‘double’ in its name. There is definitely no cause you need to bear in mind this but just observe that if you ever see DDR SDRAM mentioned anyplace, be confident to appreciate this is the actual identical point as basic vanilla DDR.
So moving on, what sorts of laptop memory do we have?
DDR notebook memory, in any other case recognized as DDR1 (even though this isn’t really an formal name instead referred to as just DDR) or DDR SDRAM is the oldest and slowest. It truly is predominantly offered in capacities up to 1GB (for every module) and at speeds of up to 400MHz (powerful).
DDR2 is an evolution to DDR with some internal enhancements to enhance overall performance and typically accessible in capacities up to 2GB (for each module) and speeds up to 1066MHz (efficient).
DDR3 is presently the most current sort of laptop computer DDR memory and is nevertheless a additional evolution of DDR2 boosting pace a additional notch. It can be located in capacities up to 4GB (for every module) and speeds up to 1600MHz (efficient).
Observe that we could have explained DDR2 SDRAM just as DDR3 SDRAM. For simplicity sake, stick to remembering that there is certainly DDR, DDR2 and DDR3 simply because very frankly this is what you may come across most! Fortunately, the business looks to prefer the shorthand naming convention.
You could also want to uncover much more about DDR, DDR2 and DDR3 notebook memory.
How do the earlier mentioned types relate to your notebook? This we are going to analyze subsequent!
What kind of DDR notebook memory do I need to have?
When upgrading laptop computer memory you want to identify what variety of DDR memory is employed therefore supported by your notebook. Failing to do this will suggest a failed upgrade for a extremely simple purpose – all versions of DDR are incompatible with every single other and use a distinct variety of slot connector, which differs in the amount of pins (and several other complex facets).
Talking of memory slots we require to introduce memory modules. In contrast to desktops your laptop uses a more compact sort of memory slot that consumes considerably less space. As a result, the memory modules utilized in laptops are smaller also. You could or may not have listened to the phrase DIMM (Twin In-line Memory Module) just before, especially if you have upgraded your desktop laptop (now is a fantastic time to jog your memory!). Laptops use SO-DIMM’s – just append ‘Small Outline’ to a DIMM. The title isn’t really critical except what this signifies in practise, particularly you are not able to install a DIMM in a SO-DIMM memory slot and vice versa. DIMM’s are considerably for a longer time than SO-DIMM’s and are not made for use in laptops. Ahead of going additional we ought to also level out that you might stumble upon SO-DIMM written as SODIMM – this is the exact same point!
So just to recap, we know the various sorts of DDR, that a variety of versions of DDR will not combine and also that we can not use any DIMM’s lying all around the house and/or place of work (should you have any) in our laptop computer. Next we need to conclude just what kind of DDR memory we want, specifically what will work in our notebook.
A great indicator what sort is correct for you is your laptop’s age. Laptops made in the several years 2001-2003 will be quite most likely be DDR dependent. Laptops made in the years 2004-2007 will be DDR2 and lastly, laptop made because 2008 will be DDR3 (even though some use DDR2). Armed with this information you will know regardless of whether to acquire a DDR SODIMM, DDR2 SODIMM or maybe a DDR3 SODIMM.
A 2nd factor you need to have to assess is the memory controller within your notebook. A straightforward strategy to discover this out (and be told what kind of DDR is correct for us) is to operate some diagnostics software on our equipment. The real truth be advised, there are tens and tens of different approaches to method this. We advise downloading and operating CPU-Z, it’s completely totally free – obtain CPU-Z below. This straightforward however valuable application will amongst other facets inform us what memory our notebook employs therefore supports (don’t forget what we stated about not mixing kinds of DDR?). Simply click on the ‘Memory’ tab and also the ‘SPD’ tab. There you will locate the title DDR, DDR2 or DDR3 adopted by different odd hunting figures these kinds of as the memory frequency and various timings. You will also discover the title that corresponds to the sub-kind of DDR notebook memory utilized by your laptop – this will be something alongside the strains of PC2-5300, PC3200, PC3-8500 and many others. Basically piece the two together (i.e. DDR2 PC2-5300, DDR PC2100, DDR3 PC8-8500) and you are going to know what to get and therefore install.
Locate out much more about DDR, DDR2 and DDR3 SODIMM modules.
We know what memory we need to have, a reasonable subsequent step is as a result to decide where to acquire it!
The place to reliably purchase DDR laptop memory
In this working day and age when the Net overwhelms in alternatives from where to buy notebook memory it really is extremely hard to provide a definitive list of protected on the web shops.

Check out out in which to buy DDR laptop memory that’s right for your notebook.
How to install DDR laptop memory
The good information is that irrespective what type of DDR laptop computer memory your notebook uses, installation is extremely considerably the very same for either. The only essential variation (besides of system for putting in each in a compatible memory slot) is that in the scenario of DDR2 and DDR3 laptops, it is excellent practise to set up memory in pairs (i.e. two modules at a time). Doing so enables the so known as twin channel mode on suitable laptops, which triggers a performance boost (increased memory throughput). If you have these kinds of a laptop computer then just remember to order two modules alternatively of one.
Most laptops function access to the memory bay beneath. For this purpose most of you will want to turn your laptop upside down. Unnecessary to say, you need to switch it off initial!

In both situation obtaining inside of (lifting the memory bay protect or comparable) will be effortless delivering you have the correct Philips screwdriver. In some situations you may want to seek the advice of your laptop’s manual (these practically constantly tells you where the memory is installed) for clues what screws require unscrewing (typically 2-three). It is essential you earth oneself throughout the entire process as electro-static impulses can harm laptop memory. Either acquire a low-cost anti-static wristband or don’t forget to touch some thing made of metal this kind of as a table leg frequently. Possibly technique will keep your body discharged and consequently risk-free for dealing with notebook memory.
Once inside of, simply remove the existing memory module by pulling the latches at both ends in an outwards path (if you require to free up space) in which situation the current module will pop up. Basically pull it out after unfastened. If you never require to totally free up space and just want to insert the new module, align the latch on the slot and module properly and then insert the module at about an angle of forty five levels. When the gold plated pins are hidden (inserted) in the memory slot, push down until finally the DDR laptop memory module clicks into location!
Next, flip on your notebook and your memory must sign-up all and well. If your notebook fails to switch on then 1 or far more memory modules may possibly not be inserted correctly, or possibly (not often) defective.
You may prefer to adhere to a stage by stage laptop computer memory illustrated set up information rather.
