Asus Maximus IV GENE-Z/GEN3 - Manual (Page 47)

• 4 DIMM slots:
1 DIMM: Supports one module inserted in any slot as single-channel
memory configuration.
2 DIMMs: Support one pair of modules inserted into either the red slots or
the gray slots as one pair of dual-channel memory configuration.
4 DIMMs: Support 4 modules inserted into both the red and gray slots as
two pairs of dual-channel memory configuration.
• When installing total memory of 4GB capacity or more, Windows 32-
bit operating system may only recognize less than 3GB. Hence, a total
installed memory of less than 3GB is recommended.
• It is recommended to install the memory modules from the red slots for
better overclocking capacity.
• 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.
