2-3 Installing DIMMs
CAUTION!!
Exercise extreme care when installing or removing
DIMM modules to prevent any possible damage. Also note that the
memory is interleaved to improve performance (see step1.)
DIMM Installation (See Figure 2-2)
1. Insert the desired number of DIMMs into the memory slots, starting with DIMM
#1A. The memory scheme is interleaved, so you must install two modules
of the same size and of the speed at a time, beginning with DIMM #1A, then
DIMM #1B, and so on.
2. When inserting a DIMM module vertically into its slot, pay attention to the
notch along the bottom of the module to prevent inserting the DIMM module
incorrectly.
3. Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules (see step 1 above).
Memory Support
The X6DLP-4G2/X6DLP-EG2 supports up to 16 GB of Reg. ECC DDRII 400
(PC3200) memory.
Notes :
1. Due to OS limitations, some operating systems may not support more than 4GB
of memory.
2. Due to memory allocation to system devices, memory remaining available
for operational use will be reduced when 4 GB of RAM is used. The reduction in
memory availability is disproportional. (Refer to the following Memory Availability
Table for details.)
