Memory
Caution!
Exercise extreme care when installing or removing DIMM modules to prevent
any possible damage.
Memory Support
The X9QRi-F+/X9QR7-TF+ has thirty-two (32) 240-pin DIMM sockets that can
support up to 1024GB of Registered (RDIMM), Load Reduced (LRDIMM) ECC or
Unbuffered (UDIMM) ECC/Non-ECC DDR3 1866/1600/1333/1066/800 MHz speed
S D R A M i n a t w o - c h a n n e l m e m o r y b u s . M e m o r y s i z e s o f
1GB, 2GB, 4GB, 8GB, 16GB and 32GB size @ 1.35V/1.5V voltage are supported.
Use memory modules of the same type, speed, timing and same on a serverboard.
Please refer to the product page on our web site for possible updates to memory
support.
Notes:
1. 1866 MHz memory is available when supported by the processors installed in
your system using the one-DIMM_per-channel memory con
fi
guration.
2. For best system performance, we recommend that a pair of CPUs (CPU1/
CPU2) or two pairs of CPUs (CPU1/CPU2/CPU3/CPU4) be installed.
Using three CPUs is not recommended. Please install your DIMM modules
according to the number of CPUs used in the system.
3. For UDIMM or other memory support details, please refer to the approved
memory list posted on our website.
4. To optimize memory performance, please install 16 DIMMs or 24 DIMMs on
the motherboard when 4 CPUs are used in the system.
Installing Memory Modules (Figure 5-3)
1. Insert the desired number of DIMMs into the memory slots, starting with P1-
DIMM #A1. The release tabs on the slot should be pushed outward.
2. 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 5-3).
3. Gently press down on the DIMM module until it snaps into place in the slot.
Make sure that the side notches of the DIMM modules align with the lock/
release tabs of the slot when pressed in. Repeat for all modules.
4. Reverse the steps above to remove the DIMM modules from the serverboard.
