CAUTION
Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage.
DIMM Installation (See Figure 2-2)
1. Insert an even number of memory modules. Interleaved memory requires
you to install two modules at a time. With the X5DL8-GG, begin from
the two slots of the last bank and working your way toward the two
slots of Bank 1. With the X5DLR-8G2+/X5DLR-8G2, you may begin
populating the slots two at a time (a full bank) from either end.
2. Insert each DIMM module into its slot. Note the notch at the bottom of the
module to prevent inserting the 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).
Support
The X5DL8-GG/X5DLR-8G2+/X5DLR-8G2 supports ECC registered DDR-266/
200 (PC2100/1600) SDRAM memory. An interleaved memory configuration
is used (see step 1 above).
The interleaved memory scheme also employs an additional performance-
enhancing feature. This feature works best when four DIMM slots are
populated, is slightly reduced when all eight slots are populated, and is
reduced slightly more with a two-slot configuration. In a six-slot configura-
tion, this performance enhancing feature is not utilized, resulting in standard
interleaved memory performance.
