Memory Support
The X7QC3 supports up to 192 GB fully buffered (FBD) ECC DDR2 667/533 in
24 DIMM slots (four channels, two branches). Single channel memory, two-way
interleaved memory and four-way interleaved memory schemes are all supported.
Using four-way interleaved memory will result in the best performance. Please use
memory modules of the same type, speed, timing and same on a serverboard.
Note: See the following table for memory installation.
Installing Memory Modules
Insert the desired number of Fully Buffered DDR2 modules into the memory
slots, starting with DIMM #A1. To enhance memory performance, install pairs
of memory modules of the same type and of the same, beginning with DIMM
#A1 and DIMM #A2, then DIMM #B1 and DIMM #B2 (see Memory Support
above).
Insert each DIMM module vertically into its slot. Pay attention to the notch
along the bottom of the module to avoid installing incorrectly (see Figure 5-4).
Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules.
