For each DRAM channel (A,B,C,D), make sure to install the DRAM module to blue slot first.
•
1 DIMM: Supports one (1) module inserted into any blue slot as Single-channel
memory configuration. Install the module into the D1 slot for better
compatibility.
• 2 DIMMs: Supports two (2) modules inserted into one pair of blue slots as one pair of
Dual-channel memory configuration. Install the modules into slots B1 and
D1 for better compatibility.
• 4 DIMMs: Supports four (4) modules inserted into four blue slots as two pairs of
Quad-channel memory configuration. Install the modules into slots A1/B1/
C1/D1 for better compatibility.
• 6 DIMMs: Supports four (6) modules inserted into four blue slots and one pair of black
slots as three pairs of Quad-channel memory configurations. Install the
modules into slots A1/B1/B2/C1/D1/D2 for better compatibility.

• ASUS exclusively provides hyper DIMM support function.
• Hyper DIMM support is subject to the physical characteristics of individual CPUs. Load
the X.M.P. or D.O.C.P. settings in the BIOS for the hyper DIMM support.
• Visit the ASUS website for the latest QVL.
• When installing total memory of 4GB capacity or more, Windows 32-bit operation system
may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is
recommended.
• The default DIMM frequency depends on its Serial Presence Detect (SPD), which is
the standard way of accessing information from a memory module. Under the default
state, some memory modules for overclocking may operate at a lower frequency than
the vendor-marked value
