Ram Slots Are Organized Electronically Into
May 14, 2013 Noob question (2 large RAM modules, or 4 small ones, which one is better) Thread starter PCJake; Start date May 11. If you had four free RAM slots on your board, which of the following would you choose: a) 16GB (2x8GB). So if you placed a single stick of memory into your motherboard, you'd be effectively utilizing a single 64-bit. Dell Latitude D610 laptop has two memory slots available for upgrades. Site to determine what memory I could upgrade with, ordered it and it arrived (free shipping) in 2 days. I put the memory into the slots as you directed, put the battery back in and started it. Now I have something to attach to my electronic embroidery machine to. Jan 09, 2014 What Does the RAM Slot Color Coding on Motherboards Mean? Jason Fitzpatrick @jasonfitzpatric Updated January 9, 2014, 2:11pm EDT Yellow and orange, blue and black, green and red: you’ll find the RAM slots on motherboards in all sorts of color pairs.
No, ram slots are organized electronically into all regulated online slot machines are completely fair. The results are random every time, meaning that nothing in the game is rigged. To ensure fair play, only choose slots from approved online casinos, such as those we list on this page. Yep, its actually very easy the ram chip just slots in but make sure that you buy ram that is compatible with your motherboard and when you slot the ram in that you pair them correctly if you have. A set-associative cache consists of 64 lines, or slots, divided into four-line sets. Main memory contains 4K blocks of 128 words each. Show the format of main memory addresses.
In computing, the form factor is the specification of a motherboard – the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. Specifically, in the IBM PC compatible industry, standard form factors ensure that parts are interchangeable across competing vendors and generations of technology, while in enterprise computing, form factors ensure that server modules fit into existing rackmount systems. Traditionally, the most significant specification is for that of the motherboard, which generally dictates the overall size of the case. Small form factors have been developed and implemented.

Overview of form factors[edit]
A PC motherboard is the main circuit board within a typical desktop computer, laptop or server. Its main functions are as follows:
- To serve as a central backbone to which all other modular parts such as CPU, RAM, and hard drives can be attached as required to create a computer
- To be interchangeable (in most cases) with different components (in particular CPU and expansion cards) for the purposes of customization and upgrading
- To distribute power to other circuit boards
- To electronically co-ordinate and interface the operation of the components
As new generations of components have been developed, the standards of motherboards have changed too. For example, the introduction of AGP and, more recently, PCI Express have influenced motherboard design. However, the standardized size and layout of motherboards have changed much more slowly and are controlled by their own standards. The list of components required on a motherboard changes far more slowly than the components themselves. For example, north bridge microchips have changed many times since their introduction with many manufacturers bringing out their own versions, but in terms of form factor standards, provisions for north bridges have remained fairly static for many years.
Although it is a slower process, form factors do evolve regularly in response to changing demands. IBM's long-standing standard, AT (Advanced Technology), was superseded in 1995 by the current industry standard ATX (Advanced Technology Extended), which still governs the size and design of the motherboard in most modern PCs. The latest update to the ATX standard was released in 2007. A divergent standard by chipset manufacturer VIA called EPIA (also known as ITX, and not to be confused with EPIC) is based upon smaller form factors and its own standards.
Differences between form factors are most apparent in terms of their intended market sector, and involve variations in size, design compromises and typical features. Most modern computers have very similar requirements, so form factor differences tend to be based upon subsets and supersets of these. For example, a desktop computer may require more sockets for maximum flexibility and many optional connectors and other features on board, whereas a computer to be used in a multimedia system may need to be optimized for heat and size, with additional plug-in cards being less common. The smallest motherboards may sacrifice CPU flexibility in favor of a fixed manufacturer's choice.

|---|---|---|---|
| XT | IBM 1983 | 8.5 × 11 in 216 × 279 mm | Obsolete, see Industry Standard Architecture. The IBM Personal Computer XT was the successor to the original IBM PC, its first home computer. As the specifications were open, many clone motherboards were produced and it became a de facto standard. |
| AT (Advanced Technology) | IBM 1984 | 12 × 11–13 in 305 × 279–330 mm | Obsolete, see Industry Standard Architecture. Created by IBM for the IBM Personal Computer/AT, an Intel 80286 machine. Also known as Full AT, it was popular during the era of the Intel 80386 microprocessor. Superseded by ATX. |
| Baby-AT | IBM 1985 | 8.5 × 10–13 in 216 × 254–330 mm | IBM's 1985 successor to the AT motherboard. Functionally equivalent to the AT, it became popular due to its significantly smaller size. |
| ATX | Intel 1995 | 12 × 9.6 in 305 × 244 mm | Created by Intel in 1995. As of 2017, it is the most popular form factor for commodity motherboards. Typical size is 9.6 × 12 in although some companies extend that to 10 × 12 in. |
| SSI CEB | SSI | 12 × 10.5 in 305 × 267 mm | Created by the Server System Infrastructure (SSI) forum. Derived from the EEB and ATX specifications. This means that SSI CEB motherboards have the same mounting holes and the same IO connector area as ATX motherboards. |
| SSI EEB | SSI | 12 × 13 in 305 × 330 mm | Created by the Server System Infrastructure (SSI) forum. Derived from the EEB and ATX specifications. This means that SSI CEB motherboards have the same mounting holes and the same IO connector area as ATX motherboards, but SSI EEB motherboards do not. |
| SSI MEB | SSI | 16.2 × 13 in 411 × 330 mm | Created by the Server System Infrastructure (SSI) forum. Derived from the EEB and ATX specifications. |
| microATX | 1996 | 9.6 × 9.6 in 244 × 244 mm | A smaller variant of the ATX form factor (about 25% shorter). Compatible with most ATX cases, but has fewer slots than ATX, for a smaller power supply unit. Very popular for desktop and small form factor computers as of 2017. |
| Mini-ATX | AOpen 2005 | 5.9 × 5.9 in 150 × 150 mm | Mini-ATX is considerably smaller than Micro-ATX. Mini-ATX motherboards were designed with MoDT (Mobile on Desktop Technology) which adapt mobile CPUs for lower power requirement, less heat generation and better application capability. |

PC/104 and EBX[edit]
PC/104 is an embedded computer standard which defines both a form factor and computer bus. PC/104 is intended for embedded computing environments. Single board computers built to this form factor are often sold by COTS vendors, which benefits users who want a customized rugged system, without months of design and paper work.

The PC/104 form factor was standardized by the PC/104 Consortium in 1992.[3] An IEEE standard corresponding to PC/104 was drafted as IEEE P996.1, but never ratified.[4]

The 5.75 × 8.0 in Embedded Board eXpandable (EBX) specification, which was derived from Ampro's proprietary Little Board form-factor, resulted from a collaboration between Ampro and Motorola Computer Group.
As compared with PC/104 modules, these larger (but still reasonably embeddable) SBCs tend to have everything of a full PC on them, including application oriented interfaces like audio, analog, or digital I/O in many cases. Also it's much easier to fit Pentium CPUs, whereas it's a tight squeeze (or expensive) to do so on a PC/104 SBC. Typically, EBX SBCs contain: the CPU; upgradeable RAM subassemblies (e.g., DIMM); Flash memory for solid state drive; multiple USB, serial, and parallel ports; onboard expansion via a PC/104 module stack; off-board expansion via ISA and/or PCI buses (from the PC/104 connectors); networking interface (typically Ethernet); and video (typically CRT, LCD, and TV).
Mini PC[edit]
Mini PC is a PC small form factor very close in size to an external CD or DVDdrive. Mini PCs have proven popular for use as HTPCs.
