Might you be out searching for DDR3 memory for a laptop but somewhat dazzled by the display of information and misinformation out there making your laptop memory upgrade all the more tricky? If we’ve guessed correctly then here’s a quick rundown on key facts of DDR3 laptop memory to get your on the right track.
What is DDR3 laptop memory?
DDR3 laptop memory is as of 2011 the latest memory technology to greet modern laptops. DDR3 is an evolution to its predecessor, DDR2 laptop memory, much in the same way as the latter was the successor to DDR and SDRAM laptop memory.
DDR3 laptop memory is faster than DDR2 due to doubling the data bus speed, an enhancement first introduced with DDR2. In DDR2 laptop memory the data bus speed ran at double the speed of the memory chips present on the DDR2 SODIMM memory module. DDR3 takes the same data bus, however runs it at twice its original frequency. Consequently, in DDR3 laptop memory, the data bus operates at four times the speed of the individual memory chips. In comparison to DDR2 laptop memory, DDR3 is capable of achieving the same memory bandwidth as DDR2 but in doing so only needs to run at half its frequency. This efficiency coupled with support for higher frequencies contribute to superior performance to that of DDR2 or older laptop memory Laptop Stand, Boyata Laptop Holder B07HBQSCM3.
Does my laptop really require DDR3 memory?
DDR3 memory started gaining popularity since its advent in late 2008. The type of memory for a laptop your own laptop requires primarily depends on the year it was manufactured. The build date (very often closely related to the purchase date and typically found on a sticker on its base or within its documentation) is a further indication.
A supportive indicator for identifying the type of laptop RAM your system requires is to run some diagnostic software.
A non-problematic method to find this out is to download and run software such as CPU-Z – it’s a free application which can be easily found via Google. Once downloaded and launched, click on its ‘Memory’ tab and subsequently also the ‘SPD’ tab. This will inform you whether your laptop uses DDR3 memory, its specification and timings. If you notice it stating DDR2 then write down the type of DDR3, examples include PC3-6400, PC2-4200, PC3-8500 and PC2-10600. Next, write down an indication that this is the type of DDR3 memory for a laptop you need to buy.
Great, I need DDR3 memory for a laptop, but how much can I install?
DDR3 laptops support between 4GB and 16GB of RAM. Some, usually older DDR3 laptops have the memory controller featured within what’s known as a northbridge chipset. Others, usually newer DDR3 laptops have a memory controller present within the CPU (Central Processing Unit) thus processor die. The exact amount supported by your laptop will depend on either – regardless whether the memory controller is external or internal to the processor.
