Most early PC motherboards (8088-based PCs, XTs, and early ATs) used socketed DIP chips for DRAM. As computer memory capacities grew, memory modules were used to save motherboard space and ease memory expansion. Instead of plugging in eight or nine single DIP chips, only one additional memory module was needed to increase the memory of the ...
The 3rd VAIO S Series was the first VAIO with a non-removable battery. Reviewers noted that the display felt quite flimsy, and that applying everyday amounts of torque, such as opening the display from one corner, would result in noticeable bending. Sony responded that this was by design, saying that under torque it would bend rather than break.
Only Sony Japan sold the VGN-U70P version directly, while both Sony and other Japanese vendors sold the lower model VGN-U50. A memory upgrade for the U50 is rumored to exist in Japan at an extremely high price. As of approximately January 2005, Sony Japan had discontinued the U70p, and introduced a new model, VGN-U71P.
The new range offers an i5 or i7 (although it is not clear if memory is dual port or triple port for the i7; it seems likely to be dual port, since varying the memory portness [check spelling] in the motherboard by CPU is a big change and because the memory choices remain 2/4/8, rather than changing to 3/6/12), a keyboard backlight, revised ...
The memory module is pressed and held in place against a bar with land grid array pin contacts which connect to the motherboard. Advantages of CAMM include lower thickness, allows for replaceable LPDDR modules, faster speeds above 6400 MT/s, higher capacities up to 128 GB per module and higher memory bandwidth. Disadvantages are that it cannot ...
Memory modules of SK Hynix. In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. [1] Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers, workstations, and servers. The first memory modules were ...
Usually, the motherboard must match the memory type; as a result, registered memory will not work in a motherboard not designed for it, and vice versa. Some PC motherboards accept or require registered memory, but registered and unregistered memory modules cannot be mixed. [4]
Because LPX form factor power supplies became ubiquitous in most computer cases prior to the ATX standard, it was not unusual for manufacturers to refer to them as "AT" power supplies (or occasionally as "PS/2" power supplies due to its use by the IBM PS/2), even though the actual AT and Baby AT power supply form factors were larger in size ...
