You have actually probably landed on this page due to the fact that you either wish to stand up to speed up with what DDR laptop computer memory is or you’re bang in the middle of attempting to upgrade your laptop but stuck what to do. Well you understand what? You have actually probably arrived on a page that can assist!
An excellent area to begin is an introduction to DDR laptop computer memory … Sorts of DDR laptop computer memory DDR represents Double Data Rate and is an improved (faster) type of SDRAM (Concurrent Dynamic Random Accessibility Memory). Basically all laptop computers marketed today in addition to those sold because circa 2002 make use of a provided (older or newer) variation of DDR laptop computer memory. Put it DDR memory is quicker than conventional SDRAM because it can transfer information on both the falling as well as rising edge of each clock cycle as well as therefore the ‘dual’ in its name. There’s absolutely no factor you must remember this yet just note that if you ever before see DDR SDRAM mentioned anywhere, be sure to value this is the specific same point as plain vanilla DDR.
So carrying on, what kinds of laptop computer memory do we have?
DDR laptop memory, otherwise referred to as DDR1 (though this isn’t an official name instead referred to as simply DDR) or DDR SDRAM is the earliest and slowest. It’s primarily readily available in capacities approximately 1GB (per module) and also at speeds of as much as 400MHz (reliable).
DDR2 is an advancement to DDR with some inner enhancements to increase performance as well as normally offered in capabilities up to 2GB (per component) and also accelerate to 1066MHz (effective).
DDR3 is presently the current kind of laptop computer DDR memory and also is yet a more development of DDR2 increasing rate a further notch. It can be discovered in abilities as much as 4GB (per component) and also speeds up to 1600MHz (effective).
Notification that we can have claimed DDR2 SDRAM just as DDR3 SDRAM. For simpleness benefit, adhere to bearing in mind that there’s DDR, DDR2 and DDR3 due to the fact that fairly frankly this is what you’ll run into most! Luckily, the market seems to prefer the shorthand calling convention.
You might additionally want to discover even more concerning DDR, DDR2 and DDR3 laptop memory.
Just how do the above kinds associate with your laptop? This we’ll analyze following
What type of DDR laptop memory do I need?
When upgrading laptop memory you require to determine what kind of DDR memory is used thus sustained by your laptop. Falling short to do this will certainly suggest an unsuccessful upgrade for an extremely simple factor – all versions of DDR are incompatible with each other and also utilize a various sort of slot port, which varies in the number of pins (as well as a number of various other technical elements).
Mentioning memory ports we require to introduce memory components. In comparison to desktops your laptop uses a smaller sized form of memory slot that takes in much less room. Consequently, the memory modules made use of in laptops are smaller sized also. You may or might not have heard the term DIMM (Double In-line Memory Component) in the past, particularly if you’ve updated your desktop (now is a fun time to jog your memory!).
Laptops make use of SO-DIMM’s – merely add ‘Small Overview’ to a DIMM. The name isn’t very vital other than what this means in practise, particularly you can not install a DIMM in a SO-DIMM memory port as well as the other way around. DIMM’s are considerably longer than SO-DIMM’s and are not developed for use in laptops. Prior to going even more we should additionally point out that you may come across SO-DIMM created as SODIMM – this is the specific very same point!
