- Gidday all,
-
- I'd just like to know about the speeds of crystals for required for
- INTEL CPUs. A friend told me that the speed of the crystal should
- *always* be twice the speed of the CPU (eg. 486DX-33 has a crystal
- running at 66 MHz, 386DX-25 => 50 MHz). Is this true for *all*
- motherboards??
-
- The question arose when we were trying to figure out why the speed of my
- floppy disk access slowed down after I changed my motherboard (from a
- 386DX-33 to 486DX2-50). Currently, it'll take about 10 seconds to access
- drive A: (Yup, a simple A: takes 10 seconds); in contrast to my 386DX-33
- which took about 1 second (3 seconds for a dir/w A:).
-
- Could someone shed some light here please??
