What are so-Dimms used for?

SO-DIMMs are often used in systems that have limited space, which include laptops, notebooks, small-footprint personal computers such as those based on Nano-ITX motherboards, high-end upgradable office printers, and networking hardware such as routers and NAS devices.

What are Simms and Dimms?

DIMM and SIMM are two major types of random-access memory standards for personal computers. DIMM is an acronym for “dual in-line memory module,” while SIMM stands for “single in-line memory module.” The naming of each type of RAM refers to the specific way in which the memory is packaged.

What is the difference between DIMM and RAM?

DIMM is long, narrow, thin circuit boards with tabs along one edge; the tabs are studded with flat metal pins that transfer data between the RAM and the computer. The RAM itself is the black, rectangular modules on the surface of the DIMM.

What words do the letters in the acronym DIMM represent?

Park, “Reduction of transient far-end crosstalk voltage and jitter in DIMM connectors for DRAM interface,” IEEE Microwave and Wireless Components Letters, Vol.

Acronym Definition

What are computer DIMMs?

A DIMM (/dɪm/) or dual in-line memory module, commonly called a RAM stick, 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, printers, and servers.

What is DIMM printer?

The printer has three dual in-line memory module (DIMM) slots for upgrading with: More printer memory. DIMMs are available in 4, 8, 16, and 32 MB, for a maximum of 100 MB. … Unlike standard printer memory, flash DIMMs can be used to permanently store downloaded items in the printer, even when the printer is off.

What is DIMM in Exadata?

Oracle® Exadata Storage Server X7-2 EF and HC Service Manual

This section describes how to service memory modules (DIMMs). DIMMs are replaceable units that require you to power off the server. For more information about replaceable units, see Illustrated Parts Breakdown and Replaceable Units.

What does DDR4 stand for?

DDR4 SDRAM is an abbreviation for “Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory.” The last dynamic RAM update was the DDR3 which came out in 2007 [1], but developers were actually already working on the DDR4 all the way back in 2005.

How many DIMMs are required to fill a bank?

Since 72-pin SIMMs are 32-bits wide, then only one is required to fill a bank in an 80386 or 80486, and the Pentium only needs two. With 168-pin DIMMs being 64-bits wide, the Pentiums only need one to fill a bank.
Size Storage Parity
2 x 64 16 MB No
4 x 64 32 MB No
8 x 64 64 MB No
16 x 64 128 MB No

What is pin RAM?

It is often used as a general term used to describe SIMM, DIMM, and SO-DIMM memory. … For example, the original SIMMs had 30 pins (which are metal contacts that connect to the motherboard). However, newer SIMM chips have 72 pins. DIMMs commonly come in 168-pin configurations, but some DIMMs have as many as 240 pins.


Stands for “Double Data Rate 4.” DDR4 is the fourth generation of DDR RAM, a type of memory commonly used in desktop and laptop computers. 1600 Mbps to 3200 Mbps data transfer rates. … 1.2 volts of electrical power required. 288 pins in a regular DIMM, 260 pins in a SO-DIMM.

Is DIMM the same as DDR4?

Physically, a DDR4 module, or dual in-line memory module (DIMM), looks very similar to a DDR3 DIMM. However, DDR4 has 288 pins compared with DDR3’s 240 pins; DDR4 SO-DIMMS have 260 pins instead of 204 in DDR3.

What does 1Rx16 mean on RAM?

Hi: The difference is the memory density. 1Rx16 is lower density memory than 1Rx8. 1Rx16 memory is very hard to find, and since the 8 GB chip is 1Rx8 and you want to add another one, that is what you should look for. Here is the crucial memory report which has compatible memory for your notebook.

What is PC4 2400t?

PC2400T refers to DDR4 running at a 300MHz memory clock with a 14.6 CAS latency and 17-17-17 timings (CL-tRCD-tRP). PC2400 is simply a non-specified variant of DDR4 with the same memory clock.

What is ROM chip?

ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain. … Originally, ROM was actually read-only.

What does 2Rx16 mean on RAM?

2R memory is often called “dual sided”, as the chips for the different ranks are usually put on opposite faces of the module. Dual rank memory (e.g. 2Rx16) has lower latency than single rank memory, because the memory ranks can be accessed independently.

What does PC4 21300 mean?

PC4 means the number of bits transferred per second. 2133 X 8 = 17060. So you motherboard spec says it support 2133 MHz speed.

What is x16 in RAM?

The “x8” and “x16” distinction is a technical spec that’s mostly a concern to someone who’s actually writing the DRAM controller. When you’re shopping around for actual memory chips, the sizes aren’t in something like 1024 MB or 512MB. … Whereas x 16 would 2 bank groups of 4 memory banks.

What does 2Rx8 mean on RAM?

1Rx8 means it is a single-rank module and 2Rx8 means it is a dual-rank module module. Rank is a data block which is 64 bits wide without Error Correction Code (ECC) created using some, or all of the memory chips on a module. The x8 in them specifies the number of banks in the memory module.

How do I know if my RAM is 1Rx16 or 1Rx8?

1RX8 sticks of memory have four “bank groups,” or groups of physical memory modules, on each stick. 1RX16 sticks, on the other hand, have only two bank groups.

What is 1Rx16?

1Rx16 means 1 rank with 16 bit wide chips, so a 64 bit wide rank uses 4 chips. Now we get into memory controllers. The memory controllers on modern CPUs can control 8 and 16 bit chips up to a specific density, the total number of bits each chip can store.

What does 1Rx4 mean?

1Rx4 means that the logical organization of the DIMM is such that it is constructed from SDRAM chips that have four data pins each. The data channel width is 64 bits (this is fixed on all modern PCs) so sixteen SDRAM chips are tied together with their data pins concatenated to form a single rank.

What does 12800s mean?

New chipsets and processors from AMD® and Intel® now support memory operating at 1600MT/s (aka 1600MHz). DDR3-1600 memory has a module classification of PC3-12800, which effectively means the peak data rate of the module is 12.8GB/sec (see table). That’s about a 17% improvement on memory bandwidth over DDR3-1333.
