Throughout the ages, civilizations have held great value on the importance of coins. From their use in real life as a means of currency, productivity, jewelry, or even when they are encountered in dreams, coins represent the distinct sign of prosperity and abundance. The coin seems to be perceived in the same manner as the circle, symbolizing the wholeness. Dream about coins may bring you new insights into how you can enhance your self-esteem.

Covering a more in-depth symbolic view, we have to recognize the fact that coins have two sides. This fact is sometimes the viewpoint apprehended in dreams, revealing the dual aspect of life. Heads and tails – the inward and the outward, the two aspects of existence – life and death.

Coins Dream Meaning

The coins that appear in your dream are a symbol of purity. In reality, you may be looking for ways to demonstrate your sincerity, honesty, and it might even be about specific fears regarding the essentials of your life.

If you have a dream about coins, it can be interpreted as a chance that might have been significant to your life. This may signify a specific thing that you value so that it can have a vast meaning. Dreaming about finding coins is a favorable aspect concerning financial gains acquired in real life.

If you dream about change, metallic money, it means that you are at a crossroads, and you seek to define your authenticity in certain situations, such as in love, in a relationship with a friend or with your family.

Depending on the amount of coins in the dream, the dream’s perception may vary. Coins in a dream are regularly apprehended to be connected to the health and abundance of the person dreaming.

If the coin is manufactured from different metals, rather than gold, silver or bronze, then this dream is connected with your struggles to succeed in life, or even so, you may experience the fear of financial instability. Each coin has its own significance, which can vary significantly.

Dreaming of Silver Coins

Silver coins symbolize spiritual expansion in your life. You can flourish spiritually and reach an elevated standard in the spiritual realm as opposed to your current phase.

The dream sign silver as a metal represents value, versatility as well as magic. Like the moon’s color, it reveals that you have a deep intuitive capacity. It is an effortlessly malleable element and thus designates the adaptability of the person who dreams about it. However, this dream can still imply other meanings.

In a dream, silver coins can also symbolize deception and betrayal, and tiny coins mean tears. A large amount of silver coins indicates good luck and wealth.

Consequently, if you offer it to someone, you’re going to endure an economic loss. If you find coins and celebrate, it implies that you will feel joyful in the actual life.

When you eat silver coins in a dream, this means that you are going to acquire some possessions. You are a person in continual change who is not pleased with your present condition, although you have more than sufficient for a proper existence. Look for innovative opportunities that enable you to feel secure and widely accepted.

Conclusion

A dream about coins, generally speaking, is an excellent indication of riches and prosperity. But perhaps the truth that not every dream can be considered on the positive aspect is worth mentioning. Otherwise, coins don’t always guarantee economic benefits, as you can create a lot of intrigues in the dream as well as in the actual life.

The dream takes on a unique significance and importance, which can be discovered in the dream books, depending on their variety of motives.

A DIMM or dual in-line memory module, commonly called a RAM stick, comprises a series of dynamic random-access memoryintegrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers, workstations and servers. DIMMs began to replace SIMMs (single in-line memory modules) as the predominant type of memory module as IntelP5-based Pentium processors began to gain market share.

While the contacts on SIMMs on both sides are redundant, DIMMs have separate electrical contacts on each side of the module. Another difference is that standard SIMMs have a 32-bit data path, while standard DIMMs have a 64-bit data path. Since Intel's Pentium, many processors have a 64-bit bus width, requiring SIMMs installed in matched pairs in order to populate the data bus. The processor would then access the two SIMMs in parallel. DIMMs were introduced to eliminate this disadvantage.

Variants[edit]

Variants of DIMM slots support DDR, DDR2, DDR3, DDR4 and DDR5 RAM.

Common types of DIMMs include the following:

70 to 200 pins

• 72-pin SO-DIMM (not the same as a 72-pin SIMM), used for FPM DRAM and EDO DRAM
• 100-pin DIMM, used for printer SDRAM
• 144-pin SO-DIMM, used for SDR SDRAM (less frequently for DDR2 SDRAM)
• 168-pin DIMM, used for SDR SDRAM (less frequently for FPM/EDO DRAM in workstations/servers, may be 3.3 or 5 V)
• 172-pin MicroDIMM, used for DDR SDRAM
• 184-pin DIMM, used for DDR SDRAM
• 200-pin SO-DIMM, used for DDR SDRAM and DDR2 SDRAM
• 200-pin DIMM, used for FPM/EDO DRAM in some Sun workstations and servers.

201 to 300 pins

• 204-pin SO-DIMM, used for DDR3 SDRAM
• 214-pin MicroDIMM, used for DDR2 SDRAM
• 240-pin DIMM, used for DDR2 SDRAM, DDR3 SDRAM and FB-DIMM DRAM
• 244-pin MiniDIMM, used for DDR2 SDRAM
• 260-pin SO-DIMM, used for DDR4 SDRAM
• 260-pin SO-DIMM, with different notch position than on DDR4 SO-DIMMs, used for UniDIMMs that can carry either DDR3 or DDR4 SDRAM
• 278-pin DIMM, used for HP high density SDRAM.
• 288-pin DIMM, used for DDR4 SDRAM and DDR5 SDRAM^[1]

168-pin SDRAM[edit]

On the bottom edge of 168-pin DIMMs there are two notches, and the location of each notch determines a particular feature of the module. The first notch is the DRAM key position, which represents RFU (reserved future use), registered, and unbuffered DIMM types (left, middle and right position, respectively). The second notch is the voltage key position, which represents 5.0 V, 3.3 V, and RFU DIMM types (order is the same as above).

DDR DIMMs[edit]

DDR, DDR2, DDR3, DDR4 and DDR5 all have different pin counts and/or different notch positions. As of August, 2014, DDR4 SDRAM is a modern emerging type of dynamic random access memory (DRAM) with a high-bandwidth ('double data rate') interface, and has been in use since 2013. It is the higher-speed successor to DDR, DDR2 and DDR3. DDR4 SDRAM is neither forward nor backward compatible with any earlier type of random access memory (RAM) because of different signalling voltages, timings, as well as other differing factors between the technologies and their implementation.

SPD EEPROM[edit]

A DIMM's capacity and other operational parameters may be identified with serial presence detect (SPD), an additional chip which contains information about the module type and timing for the memory controller to be configured correctly. The SPD EEPROM connects to the System Management Bus and may also contain thermal sensors (TS-on-DIMM).^[2]

Error correction[edit]

ECC DIMMs are those that have extra data bits which can be used by the system memory controller to detect and correct errors. There are numerous ECC schemes, but perhaps the most common is Single Error Correct, Double Error Detect (SECDED) which uses an extra byte per 64-bit word. ECC modules usually carry a multiple of 9 instead of a multiple of 8 chips.

Ranking[edit]

Sometimes memory modules are designed with two or more independent sets of DRAM chips connected to the same address and data buses; each such set is called a rank. Ranks that share the same slot, only one rank may be accessed at any given time; it is specified by activating the corresponding rank's chip select (CS) signal. The other ranks on the module are deactivated for the duration of the operation by having their corresponding CS signals deactivated. DIMMs are currently being commonly manufactured with up to four ranks per module. Consumer DIMM vendors have recently begun to distinguish between single and dual ranked DIMMs.

After a memory word is fetched, the memory is typically inaccessible for an extended period of time while the sense amplifiers are charged for access of the next cell. By interleaving the memory (e.g. cells 0, 4, 8, etc. are stored together in one rank), sequential memory accesses can be performed more rapidly because sense amplifiers have 3 cycles of idle time for recharging, between accesses.

DIMMs are often referred to as 'single-sided' or 'double-sided' to describe whether the DRAM chips are located on one or both sides of the module's printed circuit board (PCB). However, these terms may cause confusion, as the physical layout of the chips does not necessarily relate to how they are logically organized or accessed.

JEDEC decided that the terms 'dual-sided', 'double-sided', or 'dual-banked' were not correct when applied to registered DIMMs (RDIMMs).

Organization[edit]

Most DIMMs are built using '×4' ('by four') or '×8' ('by eight') memory chips with nine chips per side; '×4' and '×8' refer to the data width of the DRAM chips in bits.

In the case of '×4' registered DIMMs, the data width per side is 36 bits; therefore, the memory controller (which requires 72 bits) needs to address both sides at the same time to read or write the data it needs. In this case, the two-sided module is single-ranked. For '×8' registered DIMMs, each side is 72 bits wide, so the memory controller only addresses one side at a time (the two-sided module is dual-ranked).

The above example applies to ECC memory that stores 72 bits instead of the more common 64. There would also be one extra chip per group of eight, which is not counted.

Speeds[edit]

For various technologies, there are certain bus and device clock frequencies that are standardized; there is also a decided nomenclature for each of these speeds for each type.

DIMMs based on Single Data Rate (SDR) DRAM have the same bus frequency for data, address and control lines. DIMMs based on Double Data Rate (DDR) DRAM have data but not the strobe at double the rate of the clock; this is achieved by clocking on both the rising and falling edge of the data strobes. Power consumption and voltage gradually became lower with each generation of DDR-based DIMMs.

Another influence is Column Access Strobe (CAS) latency, or CL which affects memory access speed. This is the delay time between the READ command and the moment data is available. See main article CAS/CL

Form factors[edit]

Several form factors are commonly used in DIMMs. Single Data Rate Synchronous DRAM (SDR SDRAM) DIMMs were primarily manufactured in 1.5 inches (38 mm) and 1.7 inches (43 mm) heights. When 1U rackmount servers started becoming popular, these form factor registered DIMMs had to plug into angled DIMM sockets to fit in the 1.75 inches (44 mm) high box. To alleviate this issue, the next standards of DDR DIMMs were created with a 'low profile' (LP) height of around 1.2 inches (30 mm). These fit into vertical DIMM sockets for a 1U platform.

With the advent of blade servers, angled slots have once again become common in order to accommodate LP form factor DIMMs in these space-constrained boxes. This led to the development of the Very Low Profile (VLP) form factor DIMM with a height of around 0.72 inches (18 mm). The DDR3 JEDEC standard for VLP DIMM height is around 0.740 inches (18.8 mm). These will fit vertically in ATCA systems.

Full-height 240-pin DDR2 and DDR3 DIMMs are all specified at a height of around 1.18 inches (30 mm) by standards set by JEDEC. These form factors include 240-pin DIMM, SODIMM, Mini-DIMM and Micro-DIMM.^[3]

Full-height 288-pin DDR4 DIMMs are slightly taller than their DDR3 counterparts at 1.23 inches (31 mm). Similarly, VLP DDR4 DIMMs are also marginally taller than their DDR3 equivalent at nearly 0.74 inches (19 mm).^[4]

As of Q2 2017, Asus has had a PCI-E based 'DIMM.2', which has a similar socket to DDR3 DIMMs and is used to put in a module to connect up to two M.2NVMe solid-state drives. However, it cannot use common DDR type ram and does not have much support other than Asus.^[5]
