First and foremost, BUYSELLRAM is a company that buys and sells memory and computer accessories. We buy new and used CPUs, hard drives, computer RAM, and all other server and computer-related components. We focus on helping you dispose of the computer parts that you don’t need, but of course at a profit. Some of the products that we pay top dollar for include desktop hard drives, server hard drives, and laptop hard drives. Also, we buy laptop complete and incomplete units, servers, HBA cards, and test equipment. Among other computer assortments, we ensure that we pay you for your product. Shipping to us is easy, and we pay one business day after your item reaches us. Try us for and see what we can do for you.
Memory, also known as Random Access Memory or main memory is the computer memory that can be accessed randomly. This means that any byte of memory is accessible without interfering with the preceding bytes. Typically, all data is stored in the hard drive, but for the CPU to work during normal computer operations, data has to be read in the computer working memory, and this is where RAM becomes useful. The difference between a laptop’s and a desktop memory is quite distinct regarding performance and upgrades. More often, this factor comes into play when deciding whether to purchase a laptop or a desktop. Here at BUYSELLRAM, we deal with computer memories both new and used.
Many types of RAMs are available for desktops and computers. The most common of these is the Dual in Line Memory Module (DIMM) which are the circuit boards that hold the memory chips. Following are the main types of DIMMs.
- Synchronous Dynamic Random Access Memory (SDRAM) – it is a type of RAM that synchronizes itself with the CPU’s bus. Notably, the number that appears on the PC when looking at SDRAM indicates the system’s speed. For example, PC100 works with systems equipped with a 100 Mhz front side bus.
- Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM) – this is data that supports data transfer on both edges of both clock cycle. This helps in doubling the memory chip’s data. Also, it consumes less data ad this makes it suited for notebook computers.
- Double Data Rate Two (2) Synchronous Dynamic Random Access Memory (DDR SDRAM )– this is an upgrade of earlier types of memory and tends to be more efficient because it offers new features that allow higher operations and regarding data and clock. However, this memory is not compatible with current DDR SDRAM slots.
- Double Data Rate Three (3) Synchronous Dynamic Random Access Memory (DDR3 SDRAM) – this type of memory is preferable because it offers more bandwidth due to its increased clock rate, reduced power consumption, and a doubled pre0fetch buffer. No doubt, this is the ultimate memory for desktops.
Laptop memory is different from a desktop’s; notably, laptop’s uses the SO DIMM (Small Outline DIMM) which tends to be smaller as compared to DIMM modules used in computers. Also, one can distinguish a desktop’s memory from a laptop’s from the form factor which means the physical size and pin configuration. In this regard, a full-size DIMM is 4-5 inches in length and has 100, 168, 184, and 240 pins. On the other hand, SO DIMM is 2.5 to 3 inches in size and has 72, 100, 144, or 200 pins. Laptops also use the SO RIMM which shares similarities with SO DIMM although it has different pin numbers and uses Rambus technology.
