Random Access Memory and The SIMM Ram

RAM

In computing the random access memory, RAM stands (the corresponding English word random-access memory), is a type of computer memory characterized by allowing direct access to any memory address with the same access time.

A RAM is contrasted to sequential access storage and direct access memory against which has significantly lower access times why it is used as the primary memory.

The type of RAM is currently the most common solid-state, a read-write and volatile, but fall within the type of random access memory, most types of ROM (understood as the exception and not the most common memory read-only), the NOR flash (a type of flash memory), as well as various types of computer memory used at the dawn of computing, and now no longer used such as magnetic core memory.

SIMM Ram

The SIMM Single In-Line Memory Module is a model characterized by RAM card contacts on one side of the card.

It was introduced into the motherboard to an Intel 80386 and Motorola 68000 microprocessors, originally had a length of 3.5 inches, 30-pin and 8-bit data, were in denominations of 1, 2, 4, 8 megabytes with an access time of about 70 nanoseconds and needed a supply of 5 volts. Then they were introduced to 72-pin SIMM boards, 4.25 inches long, capable of handling 32-bit data that were used in the motherboard 486, Pentium and Motorola 680x0. Also increased the capacity of a single module, available in denominations of 4, 8, 16, 32 and 64 megabytes. For 72-pin SIMM access time also came down to 60 nanoseconds.

RAM also has a second meaning more restricted but more widespread today that RAM is the most common type of solid state, in read-write and volatile.

RANDOM ACCESS MEMORY

Ram Definition | Random Access Memory

Ram Definition The main memory of the computer work. In RAM are sent running programs and data are processed. RAM when the computer shuts down, it loses all of its contents. Part of the RAM can be included on the motherboard, although it is usually in the form of interchangeable modules SIMMs or DIMMs, which allow the expansion. There are different types of RAM DEFINITIO in the SIMM (EDO and FPM) and DIMM (SDRAM, DDR and SLDRAM).

Ram Definition is the place in which they are contained in the computer operating system, applications and data in use so they can be quickly retrieved by the processor. RAM is much faster to read and write than other storage systems such as a computer hard drive, floppy drive and CD-ROM. However, the data in RAM is retained only as long as the computer is turned on. When the computer turns off the RAM loses its data. When the computer is on, the operating system and other files must be reloaded into RAM, usually from your hard drive.

Ram Definition can be compared to short-term memory and hard drive in people with long-term memory. The short-term memory focuses on the work at hand, but few can maintain information at a time. If the short-term memory fills up, your brain sometimes is able to store information in long-term memory. Even a computer works this way. If RAM fills up, the processor must constantly access the hard drive to replace the old data in RAM with new, slowing down the operation of your computer. Unlike the hard disk that can become completely full of data and not accepting others, the RAM runs out of memory. Remains operational, but much more slowly than is desirable. This is a short articles from ram definition, hope you enjoy.

DDR-RAM

Memorie DDR2 Vs. DDR3 | are two different types of ram

What is ram you are using, Commonly that Random Access Memory (RAM) has changed over time. Towards the end of last century there was a significant difference between CL2 and CL3, depopulated when the PC133 or PC100 SDRAM. Today, the performance gap between fast and relaxed timing is almost nonexistent. The latencies of memory seem to have increased, from one generation to another memory (CL2 / 3 with DDR1, CL3-5 with DDR2, CL5 DDR3 and over with), but the changes are minor, because the frequencies are doubled to change of each generation. The actual latency, therefore, have remained more or less the same, while what is the throughput has increased considerably.

Memories for fanatics have another justification, based only indirectly on the performance: overclockers need maximum flexibility when they try to push a system to the limit. Increasing the frequency of the bus is often the only way to increase the frequency of the CPU, step that automatically increases the frequency of memory, which derives directly from the system clock frequency. No members are, of course, is willing to accept a limit imposed by the RAM, so the high-speed products are ideal for this type of activity. This scenario is valid only for the extreme overclocker, because the benefit of a faster than a slow memory is very limited, if the parameters and other components remain unchanged.

You should to Know how important timing and speed of RAM and both are two different type of ram . To reach a conclusion we have assembled an Intel socket 775 and used two different processors: the new Core 2 Duo E8500 45 nm with a frequency of 3.16 GHz and 6 MB of L2 cache, and an old Pentium 4 Extreme Edition 3, 73 GHz single core. We decided to include the P4 because it integrates a cache less and less efficient than the Core 2 Duo. Both processors have been tested with DDR2-667, DDR2-800 and DDR2-1066, and then with DDR3-1066 and DDR3-1333. Unfortunately it was not possible to test the P4 with the DDR3-1333, because that would require a 1333 MHz FSB

SDRAM | COMPARING WITH OTHER RAM

SDRAM is abbreviated from ( Synchronous Dynamic Random Access Memory, )

SDRAM work three times faster than FPM (fast page mode)RAM, If you compare with EDO RAM obviously two times faster on it. SDRAM actually synchronizes itself with the CPU's bus and is capable of running at 133 MHz, and BEDO(bee-doh ram) DRAM. SDRAM is replacing EDO ( Extended Data Out ) DRAM in many newer computers. See types of dd ram article

types of ddr ram measured by SPEED MHZ

The types of  DDR RAM memory
Double Data Rate abbreviated DDR - Double data rate or DDR2 and are distinguished by the speed of operation (the higher the speed of operation and will decrease access times to memory to store and retrieve data, and then lower the waiting time for those who use the software).

types of  DDR RAM A memory to 333MHz has an access time of 6ns ( 6 billionths of a second ) by a 466MHz has an access time of 4.5 nS. Although these values ​​appear insignificant must multiply by the enormous amount of computation that has to travel at this time and here there can be very significant differences. The DDR has 184 pins (the "feet" golden connection on the motherboard) and types of  DDR RAM :

how to get more ram to increas memory speed

How to get more ram.  First, you know type of ram and make sure you have enough virtual memory. The paging file should have at least one and a half times the size of available RAM and less than five times the amount of RAM. Anything that exceeds five times the amount of RAM is usually wasted. Secondly, the paging file must be placed in the right place. Since virtual memory is read and written constantly, it is important that the access time is fast. After verifying that the virtual memory is sufficient, this is probably the most important thing to do to improve the performance of the virtual memory system.

The ideal solution how to get more ram  is to have a separate hard drive and fast for the paging file, which is not used by the rest of the operating system or programs most used. This requires that most of the time of the disk operations is the head that moves across the disk to gain access to new information (search range). Using a separate disk for the pagefile will reduce this range.In any event, we should keep a small pagefile on the main disk. It should not be too large, because the file is usually not large, but must be fast, especially in the random access. In this way, if something happens to the disk that contains the main page file. The system will continue to function effectively and will not attempt to occupy the entire disk with a paging file. The average size sufficient to keep the hard drive is between 2 MB and does not exceed 50 MB.On systems with Windows XP and 2000 use NTFS as the file system when you format the drive with the pagefile and with models of fault-tolerant storage such as RAID 0 or RAID 5. This necessitates a further performance load, and the paging file does not need such protection. On the other hand, if you have more than a fast disk, the pagefile can benefit from RAID 0 (striping) across multiple disks, it allows an increase in performance. Groped but not to distribute the paging file on multiple volumes (logical disks) in the same physical disk, because this method slows things down. Please note that although the separate partitions on the same disk to appear as separate units, are nothing more than a single physical disk and the problem of access times is still valid.Setting the paging file and other parameters of virtual memory is simple. 

How to get more ram ,Click My Computer, select Properties, open the Advanced tab, select the Performance Options and then Settings. Reselect the Advanced tab, then click Edit under Virtual Memory. Parameters are displayed and the current settings. To change the size of the paging file, choose your settings and enter the new dimension in the Initial size and Maximum size.

TYPES OF RAM | IDENTIFY YOUR PC MEMORY

There are some types of ram, on the markets.
1. SIMM Memory (Single In-line Memory Module)
Model 30-pin:
Model 72-pin:
As aforesaid, these memories have been developed with the advent of the first Pentium processors and 386/486 (586) and Pentium Pro, so we face (even in terms of time in the computer field) in memory of "vintage ". Probably you can still see the market models of 72-pin (although very rarely), but we are the technical details:
The first (30-pin ones) are 8-bit memories, 01simm30pin-skt-l (1). jpgerano then needed four of these modules to reach the bus, so typical of motherboards that time, it was 32 ​​bit. They were introduced as models 72-pin, characterized by the fact of working with 32-bit bus, which then could also be mounted in odd numbers. With the release of the first Pentium in particular, the bus rose up to 64 bits,
2. FPM SIMM (Fast Page Mode)
Memories in fast page mode, is a "variant" of the 72-pin model. Their peculiarity is that it allows access to various bits that are all on the same line of memory, providing them one after another without pause. Their access time, in fact, is about 60 ns, especially the memories of this type that could make the phase overhead (cycles used for internal management) in 6 clock cycles, while all other stages in 3 clock cycles. The nex Types of Ram is
3. SIMM EDO (Extended Data Out) 
EDO memories are the evolution of FPM memory, because they use almost the same operating principle. But then what they have more memory? Their strong point, is the fact that while the FPM disable the column and the buffer after the "storage", the type of EDO memory buffer keeps the active, ready and then the next column until it is active or completed another cycle clock. This speeds up data storage, which will run continuously and running. Their access times ranging from 60 to 50 ns.
4. DIMM Memory (Dual In-line Memory Module)
5. SDRAM
6. SDRAM ECC
7. DIMM SDRAM DDR (Double Data Rate) and the last types of ram is
8. DDR
 Also DDR memory, there are versions ECC and Registered ECC, with a similar function to the SDRAM (ECC or ECC Registered).

RAM WIKI | memory ram computer

After disscussing to how Upgrad ram for now, i will discribe ram wiki, In computing the random access memory, RAM stands (the corresponding English word Random-Access Memory) is a type of computer memory characterized by allowing direct access to any memory address have the same access time.

The random access memory is opposed to sequential access memory and direct memory access with respect to which has much lower access times why it is used as the primary ram wiki.
The type of  what is ram ( random access memory) is currently the most common solid-state, a read-write and volatile, but fall within the type of random access memory, most types of ROM (defined by the exception and not the most common memory read-only), the NOR Flash (a type of flash memory), and various types of storage media used at the dawn of computing, and today is no longer used such as magnetic core memory.

Only the acronym RAM (not the term "random access memory") also has a second meaning smaller but more widespread now that the RAM ( how to install ram )   is a random access memory that is the most common type of solid-state, a read-write and volatile.

upgrade ram requires the least amount of time and money

Modern Operating Systems and their many services, the increasingly popular multimedia softwares (burning, video / audio editing, video / audio playing, etc..), not to mention the complex business applications, quickly absorb much of the system memory of our computers. As you know, once a "complete" physical memory, the system uses the paging file, who reside on the disk, is characterized by access times are much longer. All this means that even the newer machines, albeit powerful, showing little performance.then you must upgrade ram

A valid solution "low cost"is represented with the upgrade RAM, or by installing additional memory modules, if there are one or more slots available, or the substitution of modules pre-installed with one or more modules of larger .

upgrade ram

While the idea of "opening the PC" usually evokes a sort of "awe" on the other hand it should be noted that this type of system upgrade ram is the easiest, because requires the least amount of time and money, technical knowledge and manual intervention on your PC. if you need more asisstance how to install ram
