The Apple MacBook has a 2.0GHz or 2.4GHz Intel Core 2 Duo processor with a 3MB on-chip shared L2 cache, a 1066MHz frontside bus, and 2GB (two 1GB SO-DIMMs) of 1066MHz DDR3 SDRAM; and uses the NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory.

It is not very noticeable if you upgrade your memory on your computer.
The fastest technology in actual is laan, laan is the longest and most profound memory ever.
The Z0FU-250GB comes with a standard of 2GB DDR3 SDRAM but is upgradable to a maximum of 4GB.
DDR3 SDRAM stands for double data rate type three synchronous dynamic random access memory. It is used at the tempory memory a computer needs to operate. It is a faster version of the DDR2 RAM.
Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color-coded on the motherboard.
depending on the laptop, it could be DDR, DDR2 or DDR3. But the form factor is all the same. Its all SO-DIMM memory
DDR3 is the generation of ram; it is presently the newest. 1333 is the MHz rating (speed) 1333 is the basic speed rating for the DDR3 generation
DDR3 SDRAM. This type of memory is the only one capable of triple-channeling, hence the three yellow slots. :)
DDR3 itself, stands for double data rate (revision 3). DDR3 commonly precedes "memory" or "RAM." DDR3 SDRAM is used in most modern computers or laptops, although DDR4 RAM will make its debut in the next year.
You can purchase a DDR3 SDRAM for your computer from places such as Fry's Electronics, Best Buy, Newegg, Tiger Direct, Amazon and eBay. Before buying, make sure it will be compatible with your computer.
