单列直插式内存模块(SIMM)是指小的电路板,无论RAM芯片固定在哪里,都具有槽口。 SIMM连接器以及因此位于母板上的插槽均由金属(金或锡)制成。在SIMM中,两个小平面中存在的引脚都已连接。 SIMM呈现两种类型,一种具有30引脚,另一种具有72引脚。
双列直插式内存模块(DIMM)还具有几乎类似于SIMM的金属连接器,但是连接器的任何一个边界都不允许这样做。 DIMM支持64位通道进行数据传输,而SIMM仅支持最多32位通道。现代主板使用三种类型的DIMM礼物,一种是168针,第二种是184针,第三种是240针。
SIMM仅具有一个可用方面,因为仅具有一组工具,而DIMM在两侧具有完全不同的信号引脚,平方信号可用,并且不相信另一侧。
让我们看一下b / w SIMM和DIMM的区别:
S.NO | SIMM | DIMM |
---|---|---|
1. | In SIMM, Pins present in either facet are connected. | DIMM pins are freelance. |
2. | SIMM supports 32 bit channel for data transferring. | DIMM supports 64 bit channel for data transferring. |
3. | SIMM consumes 5 volts of power. | DIMM consumes 3.3 volts of power. |
4. | SIMM provides the storage 4 MB to 64 MB. | DIMM provides the storage 32 MB to 1 GB. |
5. | The classic or most common pin configuration of the SIMM module is 72 pins. | The foremost common pin configuration of the DIMM module is 168 pins. |
6. | SIMMs are the older technology. | DIMMs are the replacement of the SIMMs. |
7. | SIMMs are installed in pairs at a time. | DIMMs are installed one at a time. |
8. | SIMMs are used by 486 CPU as well as early Pentium computers. | DIMMs are used by modern Pentium computers. |
9. | The length and width of SIMM are respectively 4.25 inches and 1 inch. | The length and width of DIMM are respectively 1.67 to 5.25 inches and 1 to 1.75 inches. |
10. | There are single notches in SIMMs. | There are two notches in DIMMs. |
