There's DIMM SDRAM,and DDR SDRAM; a big difference! It seems they mix it up a bit! DIMM SDRAM = supposed to be 184 pin, one hole on the bottom, 2 holes on the sides, and speeds ranging somewhere like 66 to 100Mhz. (It might be possible that 33Mhz or 133Mhz exists too). DDR speeds usually go.
DDR3 is a type of SDRAM that is used for system memory. It is available in both DIMM and SO-DIMM form factors. DDR3 RAM is similar to DDR2 RAM, but uses roughly 30% less power and can transfer data twice as fast.

Two types of DIMMs: a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom). Note that the SDRAM module has two notches on the bottom edge, while the DDR1 SDRAM module has only one. Also note that both modules have 8 RAM chips, but the lower one has an unoccupied space for a 9th.

How to download cc houses sims 4 mac. A DIMM or dual in-line memory module, 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.

The main difference between SIMMs and DIMMs is that DIMMs have separate electrical contacts on each side of the module, while the contacts on SIMMs on both sides are redundant. Another difference is that standard SIMMs have a 32-bit data path, while standard DIMMs have a 64-bit data path. Setting up microsoft exchange on mac. Since Intel's Pentium has (as do several other processors) a 64-bit bus width, it requires SIMMs installed in matched pairs in order to complete the data bus. The processor would then access the two SIMMs simultaneously. DIMMs were introduced to eliminate this practice.

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
168-pin DIMM, used for SDR SDRAM (less frequently for FPM/EDO DRAM in workstations/servers)
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
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

168-pin SDRAM

On the bottom edge of 168-pin DIMMs there are 2 notches, and the location of each notch determines a particular feature of the module.

The first notch is DRAM key position. It represents RFU (reserved future use), registered, and unbuffered (in that order from left to middle to right position).
The second notch is voltage key position. It represents 5.0V, 3.3V, and Reserved (order as above).
The upper DIMM in the (topmost) photo is an unbuffered 3.3V 168-pin DIMM. DIMM slots support also DDR1, 2, 3 RAM.

DDR DIMMs

DDR, DDR2 and DDR3 all have a different pin-counts, and different notch positions.

SPD EEPROM

A DIMM's capacity and timing 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.

Error correction

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

Main article: Memory rank

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. Since all ranks share the same buses, only one rank may be accessed at any given time; it is specified by activating the corresponding rank's chip select (CS) signal. All other ranks 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.

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.

Organization

Most DIMMs are built using '×4' (by 4) memory chips or '×8' (by 8) memory chips with 9 chips per side. '×4' or '×8' refer to the data width of the DRAM chips in bits.

In the case of the '×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).

Speeds

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.

SDR SDRAM DIMMs - These first synchronous registered DRAM DIMMs had the same bus frequency for data, address and control lines.

PC66 = 66 MHz
PC100 = 100 MHz
PC133 = 133 MHz

Garmin gps download free. DDR SDRAM (DDR1) DIMMs - 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.

PC1600 = 200 MHz data & strobe / 100 MHz clock for address and control
PC2100 = 266 MHz data & strobe / 133 MHz clock for address and control
PC2700 = 333 MHz data & strobe / 166 MHz clock for address and control
PC3200 = 400 MHz data & strobe / 200 MHz clock for address and control

DDR2 SDRAM DIMMs - DIMMs based on Double Data Rate 2 (DDR2) DRAM also have data and data strobe frequencies at double the rate of t
