Mem ory In stal la tion
The EBC-LP supports a single, user-instal la ble 168- pin stan dard DIMM. DIMM mod ules should
be a minimum speed of PC-66 or PC-100 and x64 as there is no sup port for the par ity or ECC bits
pro vided by x72 bit mod ules. A sin gle DIMM socket is pro vided which can sup port SDRAM sizes
from 32MB to 256MB. For a list of qualified DIMMs, go to
http://www.winsystems.com/memory.
In stal la tion is ac com plished with power off by in sert ing the DIMM module directly into the
con nec tor at M1. The DIMM mod ule is keyed in 2 places and can not be in serted back wards with out
ex treme force. The module is inserted un til the re tain ing clips snap into place. Re moval is the re verse
pro cess. Push down on the re tain ing clips, moving them out ward. The DIMM mod ule, once re leased,
will be forced up to an appropriate removal position.
