This is a tricky question and for that reason we have devised series of points that shall give you a clarity on types of RAM and which one suits your needs the most, use this information to your benefit.
• How many types of memories ? – There are several types of RAMs, such as DDR, DDR2, DDR3, DDR4, So-Dimm, SDRAM etc, check which one is compatible with your system specs.
• Which Frequency ? – Motherboards are designed to accept only certain type of frequency for RAM, for example DDR3 will only accept up to 1300 MHZ. Because of motherboard limitations, picking a faster memory type might not add extra value to your system and picking a slower memory type can limit the overall performance of your laptop. You will need to find a healthy balance between memory type that goes well with your laptop build.
• Timing – Latencies or timings, normally refer to the overall interval or delay between different commands executed by laptop’s memory sub system. To keep it simple, you will ideally want to go with lower timing as they would decrease the latency.
• 32 Bit vs 64 Bit – 32 bit operating systems are limited to hold upto 4 GB of collective memory, that also includes RAM on your video card. On the other hand 64 bit OS can hold fairly large amount of memory. If you plan to use more than 4 GB of memory, it would be best to pick 64 bit OS to make the most out of your RAM.
• How much memory I need ? – It all boils down to your requirement and system specifications, there are limitations as to how much memory you can load onto your system, the limit varies with the type of mother board and operating system. Read the motherboard manual to find out exact limits.
• What do I need to know about pricing ? – Prices may vary from vendor to vendor – even for the same type of RAM. You will come across instance where there is only a marginal differences between the performance, but huge difference in prices, for that reason compare memory types and their performances before you decide on which one to buy.
