Recommended SIMM Manufacturers

SIMMs from Goldstar, Motorola, NEC, Samsung, Siemens, Texas Instruments, and Toshiba

have been successfully tested with the ICP Controllers. This recommendation does not im-

ply an evaluation of quality. SIMMs from other manufacturers may be equally suitable. You

can use single- and double-sided SIMMs. When using double-sided SIMMs with high power

consumption special care should be taken that both, the ICP Controller and SIMM are

properly cooled.

SIMM sizes and types which can be used on the ICP Controller :

Fast Page Mode (FPM) SIMM,

60ns (or less), Jumper S1 not set

Extended Data Out (EDO) SIMM,

50ns

(*)

Jumper S1 set

RAM Size

1M*32 and 1M*36 1M*32 and 1M*36 4MB

2M*32 and 2M*36 2M*32 and 2M*36 8MB

4M*32 and 4M*36 4M*32 and 4M*36 16MB

8M*32 and 8M*36 8M*32 and 8M*36 32MB

16M*32 and 16M*36 16M*32 and 16M*36 64MB

32M*32 and 32M*36 32M*32 and 32M*36 128MB

(*)

When using an EDO SIMM on the ICP Controller, jumper S1 has to be set (see last pages

of chapter A). For the operation of a Fast Page Mode SIMM S1 must remain open. We have

tested several EDO SIMMs with 60ns without any problems, but according to the specifica-

tion of the ICP Controller's Intel i960 CPU, 50ns are necessary to comply with the timing

requirements.

Obviously, the question arising at this point is: "How much cache RAM do I need ?"

In the following table, we made RAM equipment suggestions for the minimum, typical and

optimum RAM size (Note: Naturally, all ICP Controllers work flawless with the smallest

RAM size stated in column 2 of this table).
