Micronics W6-LI manual System Memory

Chapter 3: Installing the W6-LI

System Memory

For long term reliability, Micronics recom- mends using DIMMs with gold-plated contacts. The use of tin-plated contacts may conflict with the gold alloy on the

DIMM socket.

System memory is necessary to operate the W6-LI system board. The W6-LI uses DIMMs, which provide a wider data path than SIMMs, to carry more data.

The W6-LI has four 168-pin DIMM sockets for a maximum of 512 Megabytes of RAM. Support is provided for EDO DRAM memory and FPM DRAM memory. This chapter will explain the type of DIMMs supported, list the rules for adding memory to the W6-LI, give some examples of com- mon memory configurations and show how to physically install the new DIMMs.

DIMMsSupported

The W6-LI supports the following types of 60 or 70ns DIMMs:

8MB(1Mx64/72) 16MB(2Mx64/72) 32MB(4Mx64/72) 64MB(8Mx64/72)* 128MB(16Mx64/72)*

*Subject to availability

AddingMemory

The following is a list of rules to follow when upgrading DIMMs. If you follow these rules, your upgrade should be trouble-free:

❏Use 70ns or faster DIMMs.

❏There are three (3) types of DIMM wiring configura- tions: Non-parity - 64 bits wide, Parity and Error Checking and Correction - 72-bits wide.

❏All three types of DIMM configurations may be used on the W6-LI, but not simultaneously.
