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 ...
Dual-channel memory slots, color-coded orange and yellow for this particular motherboard. Dual-channel-enabled memory controllers in a PC system architecture use two 64-bit data channels. Dual-channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. The two technologies are independent of ...
IBM added a RAM drive named VDISK.SYS to PC DOS (version 3.0) in August 1984, which was the first DOS component to use extended memory. VDISK.SYS was not available in Microsoft's MS-DOS as it, unlike most components of early versions of PC DOS, was written by IBM. Microsoft included the similar program RAMDRIVE.SYS in MS-DOS 3.2 (released in ...
MSDN Article: Memory Limits for Windows Releases; The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed – explains the issue; Windows Vista SP1 includes reporting of Installed System Memory (RAM) – details about the RAM limit
In both, RAM near the 4 GiB point conflicts with memory-mapped I/O space. Either the BIOS simply disables the conflicting RAM; or, the BIOS remaps the conflicting RAM to physical addresses above the 4 GiB point, [citation needed] but x86 Windows client editions refuse to use physical addresses higher than that, even though they are running with ...
1U 1-slot 32-Bit PCI Riser Card 2U 3-slot 32-Bit PCI Riser Card. A riser is usually connected to the mainboard's slot through an edge connector, though some, such as NLX and Next Unit of Computing Extreme, instead are plugged into an edge connector on the mainboard itself. In general, the main purpose is to change the orientation of the ...

It has a 10 MHz 286 (surface-mounted) and 512 KB of RAM, and unlike other 286-based Tandy 1000 models, it supports 384 KB of extended memory when RAM is expanded to the maximum 1 MB. However, it is not a full AT-class machine, as it still has an 8-bit ISA bus (as with the RL, one half-size expansion slot) and only 8 IRQs and 4 DMA channels.
