Simm Speeds

SIMMs came in 32 Pin and 72 Pin.

What was the speeds that the 30 Pin and 72 Pins SIMMs ran at?

 

SIMMs (Single Inline Memory Module(s)) are old technology. Most current Memory Modules are DIMM (Dual Inline Memory Module). What type of computer do you have that uses SIMM?

 

It depends on the specific stick. Most ran at 60ns or 70ns. Some 30-pin ran at 80ns. But note the motherboard BUS speed determined the speed it actually ran at.

The basic conversion formula is T = 1/F or F = 1/T where T = Time and F = Frequency.

So 60ns = 16.6MHz. 70ns = 14.2MHz and 80ns = 12.5MHz.

In addition to 30 and 72-pin SIMMs, there were also 64-pin and 68-pin used by Apple computers.

 

I do not use SIMMs I am keeping a chart of SIMM Types and I want to keep the speed they ran at.

 

Interesting. I'm sure Digerati answered your question.
