What is Compatibility and Memory Density Issue?
Memory module can be composed using different type of memory chips and therefore created different type of density for the module. For instance, a 1GB PC2-6400 800Mhz DDR2 SODIMM memory can be composed using eight 128x8(High Density 1Gb technology) memory chips or sixteen 64x8(Low Density 512Mb technology) memory chips. As the laptops are equipped with different memory chipsets, some older laptop (chipset) would have compatibility issue working with the modules that is built with the newer 1Gb technology. Using the Not-Compatible memory will result the laptop to either not boot or only recognizing half of the memory modules. Thus that is not the correct memory for your system. Our Memory Finder and Memory Scanner will help to eliminate those problems and find the correct memory for you. We guaranteed the memory to work or your money back.
Which memory should I buy?
It is recommended to buy one module with bigger capacity than two modules with smaller capacity so you can leave the empty slot for future upgrade. For instance, if you can buy either one 2GB memory module or two 1GB memory modules for your system, it is recommended to get one 2GB and leave the other memory slot empty for future upgrade if necessary. It is recommended to buy the faster memory when there are more than one speed available for faster speed. For instance you should buy the DDR2-PC6400 800Mhz instead of the DDR2-PC5300 667Mhz when both of them are compatible with your system. Note: For systems that supports dual channel memory mode, although memory modules need to be installed in pairs to enable Dual Channel Memory Mode, we still recommended users to purchase one bigger module than two smaller modules since Dual Channel Memory Mode has only a minimal improvement on the actual system performance.
Can I mix different memory together?
Mix and match is ok with computers in now days. Different sizes/speeds of memory can be used together as long as their specification are qualified by the systems. For instance, a laptop can use one 512MB and one 2GB of memory for the total of 2.5GB system memory. Mixing two different speeds of memory modules would result the system to run at the speed of the slower memory between the two modules. We recommend users to use our Memory Finder or Memory Scanner to find the correct memory for your system.
How much memory do I need?
Find out what type of users you are first. Light User: The system is mainly used for checking e-mails, processing word/excel file, and web surfing with Windows XP or older operating systems. Suggestion: 1GB or above for system memory. Standard User: The system is mainly used for playing computer games, editing photos/videos, running database queries, or multi-tasking environment with Windows Vista, Windows 7, or Mac OS X . (Surfing web/Processing Word/Excel File/Listening to Music). Suggestion: 2GB or above for system memory. Power User: The system is mainly used for running large number of database queries, professional editing of photos/videos, heavy multi-tasking environment. Usually a server or a workstation would be considered as Power User due to the multiple accesses from users. Suggestion: 4GB or above for system memory.
