- I have a 386-33dx w/ 4Mb of 80ns 1MB simms and OPTI/AMI ROM bios
- w/ a 64K cache.
-
- Currently, I have to set my BIOS for 1 wait state read (0 wait write).
- If I set it to 0 wait state read, then the machine will not boot and
- hangs just following POST. I assume this is due to having too slow of
- memory.
-
- My question is, if I upgrade to 70ns 1MB SIMMS, will I be able to run
- at 0 wait state for memory reads or will I still need the 1 wait state?
- If so, given I have a 64k cache and generally run under windows, how
- much difference would this make?
-
- A different question: what is the effect of the cache if the access to
- memory is 0 wait states? Does the cache make it any faster or is it
- only improve speed when 1 or more wait states if involved? If it is
- faster, why?
-
- Thanks.
