An additional 4 MB of Fast RAM can be added in the PC Card slot using a suitable SRAM card to reach a capacity of 6 MB. However, additional Fast RAM can be added with unofficial memory or CPU upgrades. For example, the A608 [18] board adds up to a maximum of 8 MB additional RAM by connecting over the original 68000. Likewise, CPU upgrades can ...
The highest-rated DDR2 modules in 2009 operate at 533 MHz (1066 MT/s), compared to the highest-rated DDR modules operating at 200 MHz (400 MT/s). At the same time, the CAS latency of 11.2 ns = 6 / (bus clock rate) for the best PC2-8500 modules is comparable to that of 10 ns = 4 / (bus clock rate) for the best PC-3200 modules.
Whereas Microsoft mice and Microsoft keyboards were previously controlled from two separate programs – IntelliPoint and IntelliType – the Mouse and Keyboard Center is responsible for both kinds of devices. 32- and 64-bit versions of the software are available, and the program integrates with Windows 8 and above's "Modern UI" interface.
DDR4 RAM operates at a voltage of 1.2 V and supports frequencies between 800 and 1600 MHz (DDR4-1600 through DDR4-3200). Compared to DDR3, which operates at 1.5 V with frequencies from 400 to 1067 MHz (DDR3-800 through DDR3-2133), DDR4 offers better performance and energy efficiency. DDR4 speeds are advertised as double the base clock rate due ...
This ability allows them to be very fast, since reading and writing data from/to RAM is much faster than on a hard disk drive or solid-state drive. Many of these operating systems will load from a removable media such as a Live CD or a Live USB stick. A "frugal" install can also often be completed, allowing loading from a hard disk drive instead.
Synergy is a software application for sharing a keyboard and mouse between multiple computers. It is used in situations where several PCs are used together, with a monitor connected to each, but are to be controlled by one user. The user needs only one keyboard and mouse on the desk—similar to a KVM switch without the video.
It is designed to leverage features introduced in Windows Vista, namely ReadyBoost (a supplementation of RAM-based disk caching by dedicated files on flash drives, except on the 512 MB version) and/or ReadyDrive (a non-volatile caching solution, i.e. an implementation of a hybrid drive, as long as the main storage isn't already one); [5] as ...
