It's always better to have two memory sticks of equal size than one of larger size because when you use one stick, you lose the dual channel memory which is better than single channel.
Sorry, there was a problem. Please try again later.You should ALWAYS attempt matched pairs of RAM to make best use of your PCs memory controller. It is dual channel in MOST cases, which is like NOT putting apples in a box one by one, or taking them out the same way, but as if using two hands. almost twice the speed! :D
Sorry, there was a problem. Please try again later.One thing to verify is the number of module slots. So if you have two slots, then install 2X4gb modules. However, if you system has two slots and each slots can work on its own (does not need the other covered to operate) then 1 8gb will work and you will have one open slot to add memory later. Also note some laptops (due to limitation of motherboard and BIOS) can only to upgrade to a certain level. If 8gb is your max memory threshold, then use the 2ea 4gb modules.
Sorry, there was a problem. Please try again later.First you need to know what the maximum memory supported by the motherboard and bios is. Second, if your Windows OS is 32 bit you will not gain any benefit from the upgrade. 32 bit will only address 3gb with the extra 1gb used for video. In theory 2 sims should always be faster than 1 but if you want to go to 16gb someday you should go with the single 8gb. Your computer would possibly support leaving one of the 2gb in with the 8gb giving you 10gb total.
Sorry, there was a problem. Please try again later.you should upgrade it with 2x 4gbs cards, never have two different ram cards
Sorry, there was a problem. Please try again later.
