All DIMMs must be 112-pin, fast-paged mode, 70-nanosecond access time or faster. The
PowerCenter has three VRAM DIMM slots near the front on the motherboard. If one VRAM
DIMMs is to be installed, it must be installed in the slot closest to the front of the logic board.
This gives a total of two megabytes of VRAM. Adding two VRAM DIMMs, providing three
megabytes of VRAM, is not a supported configuration. Adding three VRAM DIMMs to give a total
of four megabytes of VRAM is the next valid, supported configuration.
Removing VRAM
1. Remove the chassis cover (
refer to
Chassis Cover Removal/Installation
on page 6).
2. Place the unit on its side with the MLB on the bottom and the open side facing up.
3. Locate the VRAM DIMM(s) you would like to remove (
refer to
MLB Diagram
on page 5).
Loosen the
desired DIMM module by reaching in and pushing down on the small lever at the end of the
DIMM slot. (
see
Figure 6
on page 11).
The DIMM should pop loose from the slot at the lever end.
4. Grasp the DIMM module on each end and evenly pull the module up and out of the slot.
Installing VRAM
1. Hold the module (with the contacts down) with one hand at each end. Notice that there are two
notches in the contact edge of the DIMM module.
