DRAM Chip Speed
The PEM-3300/PEM-3301 mainboard has a clock speed which re-
quires the use of 80ns DRAM on the ‘386 RAM Board. For other
mainboards, refer to your mainboard manual or contact your dealer.
Both types of DRAM (256KB and 1MB) are available in both speeds
so you can take full advantage of the ‘386 RAM Board’s various
configurations. Refer to the charts below for a synopsis of this infor-
mation.

Total System Memory Size
The PEI-306 RAM Board provides you up to 16MB of total system
memory.

that of the PEI-306 extension memory card.
Note:
You only can have 16MB maximum of
total system memory.
Refer to the following pages for more information.
Note for the following pages:
* We support this kind of module RAM. There are two banks of DRAM
mounted on each RAM module.
**Due to address limitations, this configuration cannot accommodate
an AT bus RAM card.
** 16MB maximum total system memory has no starting address.
