What is SDRAM? SDRAM stands for Synchronous Dynamic Random Access Memory, and it is a fast method of delivering computing capacity. It can run at 133 Mhz, which is much faster than earlier RAM technologies. This type of memory is very protective of its data bits, storing them each in a separate capacitor. The benefit of this is that it avoids corruption and maintains pristine data.

- The motherboard's manual provides the information on the types of RAM that the motherboard can run. You must set the RAM clock speed (in the BIOS, or by setting jumpers on the motherboard) to the speed of the RAM that your purchase. This is 133MHz for PC2100 and 166MHz for PC2700 DDR RAM.o. Even though there are systems that support both technologies, you can't have DDR and SDRAM in the same system at the same time. You'll have to choose one or the other. You can use some of the easy tools to find your exact DDR or DDR2 Memory Upgrades for your Desktop, Laptop or Servers.

- If the divisor is x8 the memory is low density. If the divisor is x4 the memory is high density. DDR2 and later memory modules usually include density information on the label. 1Rx8 or 2Rx8 are low density, 1Rx4 or 2Rx4 are high density (usually server RAM).There is no high density Non-ECC unbuffered desktop RAM produced by major memory manufacturers because it does not comply with JEDEC standards.f the divisor is x8 the memory is low density. If the divisor is x4 the memory is high density.

DIMM Also, each module has eight RAM chips, but the lower one has an unoccupied space for the ninth chip. Three SDRAM DIMM slots on a computer motherboard. A DIMM or dual in-line memory module comprises a series of dynamic random-access memory integrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers, workstations and servers.

- most common single data rate (SDR) SDRAM transfers data on the rising edge of the clock. The other is the dou-ble data rate (DDR) SDRAM which transfers data on both the rising and falling edge to double the data transfer throughput. Other than the data transfer phase, the different power-on initialization and mode register definitions,

How to Detect the Type of RAM in a PC The Task Manager opens. 3. Click the “Performance” tab, and then select the “Memory” side tab. 4. Check the upper-right side of the Task Manager window to see the type of RAM installed on your computer. Different types of RAM include DDR SDRAM, DDR2 SDRAM and DDR3 SDRAM. Resources (2)

Double Data Rate (DDR) Double Data Rate (DDR) Definition - What does Double Data Rate (DDR) mean? Double data rate (DDR) is the advanced version of synchronous dynamic random access memory (SDRAM). SDRAM waits for clock signals before responding to control inputs. DDR uses both the falling and rising edges of the clock signal. The difference between SDRAM and DDR is not the speed, but rather how many times data is transmitted with each cycle.

Different RAM Types and its uses Different RAM Types and its uses. The type of RAM doesn't matter nearly as much as how much of it you've got, but using plain old SDRAM memory today will slow you down. There are main types of RAM: SDRAM, DDR and Rambus DRAM. Almost all systems used to ship with 3.3 volt, 168-pin SDRAM DIMMs.

- Lesson Summary. RAM stands for random-access memory, which makes it possible to find specific information very quickly. It is a form of fast-access, volatile storage that is used as the main memory in computer systems. The most widely used form of RAM for the main memory is dynamic RAM (DRAM) .

SDRAM (synchronous DRAM) SDRAM (synchronous DRAM) SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.

WHAT IS THE DIFFERENCE BETWEEN GDDR5 AND DDR3 RAM?! I don't think there's a good example... ddr3 ram is ram that you put on your PC motherboard and costs like $40 for 4 gigs. GDDR5 ram is super fast and (i thought) expensive ram that you find on graphics cards, its $1,000 for a graphics card with 6gigs of GDDR5 ram.

DDR SDRAM Beginning in 1996 and concluding in June 2000, JEDEC developed the DDR (Double Data Rate) SDRAM specification (JESD79).. JEDEC has set standards for data rates of DDR SDRAM, divided into two parts. The first specification is for memory chips, and the second is for memory modules.

DRAM - What is the difference between a DIMM and SODIMM? DDR, DIMMS and SODIMM are both memory modules used in computers. DIMMs are used in desktop computers and servers. A DIMM (133MM) is about twice as long as a SODIMM (67MM). DIMMs can carry features not normally found on SODIMMs such as ECC and REGISTERED. SODIMMs are used in notebook computers.

RAM - random access memory DRAM (Dynamic Random Access Memory) – The term dynamic indicates that the memory must be constantly refreshed or it will lose its contents. DRAM is typically used for the main memory in computing devices. If a PC or smartphone is advertised as having 4-GB RAM or 16-GB RAM, those numbers refer to the DRAM, or main memory, in the device.

Ch6 Supporting Processors SRAM Performance improves because RAM stored in memory modules (DIMMs) on the motherboard is dynamic RAM or DRAM and memory in a memory cache is static RAM or SRAM. Dynamic RAM loses data rapidly and must be refreshed often. SRAM does not need refreshing and can hold its data as long as power is available.

RAM or Main Memory â PC / computer memory (DIMM, DRAM, SDRAM) RAM or Main Memory – PC / computer memory (DIMM, DRAM, SDRAM). A PC’s third and principal level of system memory is referred to as main memory, or Random Access Memory (RAM). It is an impermanent source of data, but is the main memory area accessed by the hard disk. It acts, so to speak, as a staging post between the hard disk and the processor.

DDR2 SDRAM DDR2 DIMMs are not backward compatible with DDR DIMMs. The notch on DDR2 DIMMs is in a different position from DDR DIMMs, and the pin density is higher than DDR DIMMs in desktops. DDR2 is a 240-pin module, DDR is a 184-pin module.he key difference between DDR and DDR2 is that for DDR2 the memory cells are clocked at 1 quarter (rather than half) the rate of the bus. This requires a 4-bit-deep prefetch queue, but, without changing the memory cells themselves, DDR2 can effectively operate at twice the bus speed of DDR.

DRDRAM (Rambus Dynamic Random Access Memory) Also see RAM types. Rambus Dynamic Random Access Memory (RDRAM) is a memory subsystem that promises to transfer up to 1.6 billion bytes per second. The subsystem consists of the random access memory, the RAM controller, and the bus (path) connecting RAM to the microprocessor and devices in the computer that use it. Direct Rambus (DRDRAM), a technology developed and licensed by the Rambus Corporation, will be used with microprocessors beginning in 1999.

Synchronous dynamic random-access memory SDRAM is widely used in computers. Beyond the original SDRAM, further generations of double data rate RAM have entered the mass market – DDR (also known as DDR1), DDR2, DDR3 and DDR4, with the latest generation (DDR4) released in second half of 2014.

What is the difference between DDR, DDR2, DDR3 and DDR4 RAM? DDR RAM stands for Double Data Rate Random Access Memory. Double Data Rate means that it can fetch data on both the up and the down cycles of the clock, unlike the previous versions of RAM which only fetched on one clock edge. The original D...

What is Random-Access Memory? Random-access memory (RAM) is a type of computer data storage. A RAM device makes it possible to access data in random order, which makes it very fast to find a specific piece of information. Certain other types of storage are not random-access.

Questions & Answers The SDR or the ‘Standard Dimension Ratio’ and refers to the geometry of the pipe. SDR is defined as the ratio of the nominal outside diameter to the nominal wall thickness. It is common to use the SDR as a method of pressure rating pipes. Therefore a higher SDR indicates a thinner-walled pipe at any given diameter. Common SDR’s are : 7.4, 9, 11, 13.6, and 17.

What is RAM? RAM is an acronym for Random Access Memory. It is a type of computer memory akin to a person's short-term memory. Data that must be accessed quickly is kept in RAM, such as running applications and open files. When a computer does not have enough RAM, it is forced to allocate part of the hard disk in place of the missing RAM, which hurts performance. Modern operating systems such as OS-X, Windows XP, or Linux need about 256 MB of RAM to perform satisfactorily, and 'heavy' operating systems such as Windows Vista require 1 GB (1025 MB) of RAM to run.
