- Hello, you can find out the speed of the SIMMS from the chip itself. On
- the first row of codes, the last 2 digits indicate the speed of the
- chips. For Eg, 70 means 70 ns, 12 means 120 ns, 10 means 10 ns and so
- on.
-
- Different speeds of SIMMs on different banks should not pose any problem
- to the system, but the RAM read/write wait state must be set to the
- slower RAMs.
