Installing a memory module

The following notes describe the types of dual inline memory modules (DIMMs) that

the server supports and other information that you must consider when installing

DIMMs:

v The server supports up to 12 Fully Buffered DIMM PC2-5300 512 MB, 1 GB, 2

GB, and 4 GB DIMMs, for a maximum of 48 GB of system memory. See

http://www.lenovo.com/thinkserver/ for a list of memory modules that you can use

with the server.

Note: Because some memory is reserved for system operation, the actual

usable memory size that is reported by the operating system is less than the total

installed size.

v The server comes with a minimum of two 512 MB DIMMs, installed in slots 1 and

4. When you install additional DIMMs, you must install two identical DIMMS at a

time, in the order shown in the following table, to maintain performance.

Table 3. DIMM installation sequence

1 1 and 4

2 7 and 10

3 2 and 5

4 8 and 11

5 3 and 6

6 9 and 12

Note: When only one pair of DIMMs is installed in the server and the BIOS code

level is version 1.04 (GGE127A) or later, you can improve performance by

installing the DIMMs in connectors 1 and 7 instead of 1 and 4. However, because

the connectors in the pair are not on the same memory branch (see the following

illustration), Advanced ECC memory protection is disabled.
