Memory Loading Rules And Guidelines - HP Integrity rx3600 Installation Manual

Memory Loading Rules and Guidelines

Use the following rules and guidelines when installing memory:
Install DIMMs in pairs for the 8-DIMM memory carrier and quads in the 24 DIMM memory
carrier.
Ensure that all DIMMs within a pair or quad are identical.
Install pairs or quads in order of capacity from largest to smallest. For example, install all 2
GB quads before 1 GB or smaller quads, and install all 1 GB quads before 512 MB quads.
Side 0 must have equal or greater memory capacity than side 1.
Install DIMM pairs or quads based on the following rules:
1. Load pairs or quads into the memory carrier in order, starting with slot 0 and ending with
slot 2.
2. Install the first pair or quad in side 0.
3. Install the second pair or quad in side 1.
4. For the remaining pairs or quads:
a.
b.
c.
Table 7 shows several examples of proper memory carrier loading order.
NOTE: The number in parenthesis indicates the order in which the quads are loaded.

26 Installing the System
If both sides of the memory carrier contain the same capacity of memory, install the
next pairs or quad in side 0.
If side 0 contains more memory capacity, even though it may have less DIMMs than
side 1, install the next pair or quad in side 1.
If side 1 is full, install the remaining pairs or quads in side 0.
