I've got 2 megs worth of 100ns 256kx1 dynamic ram chips. What speed 386 motherboard will they work with? What speed 286 mother board will they work with? Interleaved? Cached? 1 wait state? 0 wait state? -- <Dennis Lou> |"But Yossarian, what if everyone pa1568@sdcc13.ucsd.edu | thought that way?"

Cached? 1 wait state? 0 wait They will run in a 20 mhz interleaved motherboard - and might even run in a 25 mhz interleaved motherboard with 1 wait state (I have used 100ns RAM at 25/1 without problems).

100ns RAM will work on an 8 MHz AT at 0 wait states, on a 12 MHz AT
at 1 wait state, and perhaps on a 10 MHz AT at 0 wait states (but 10 MHz
ATs are pretty uncommon)

As a matter of fact my clone vendor (Zeos) recommended 100ns RAM. For what it's worth, Dru 'I hate stupid signature files.`

100 ns are fine in At's 12 Mc. with 0 wait. If you go any faster, you should use 80's.

Depends on what machine you use. Some AT's allow 120 ns memory to be used at 12MHz, 0 wait. The logic on your motherboard has some say in what RAM speed to use. Also, on XT boards, you can pretty safely use slower RAMS. I have a 15 (Yes, ONE FIVE) MHz V20 board happily running using 100ns chips, zero wait, of course. Kwong
