    For more details, refer to the Microsoft support site at http://support.microsoft. ® com/kb/929605/en-us. • The design of the DIMM fan may vary. Ensure that the DIMM fan fits to the motherboard • The default memory operation frequency is dependent 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. • For system stability, use a more efficient memory cooling system to support a full memory load (4 DIMMs) or overclocking condition. • Memory modules with memory frequency higher than 2133MHz and their corresponding timing or the loaded XMP profile is not the JEDEC memory standard. The stability and compatibility of the memory modules depend on the CPU’s capabilities and other installed devices. • Always install the DIMMS with the same CAS Latency. For an optimum compatibility, we recommend that you install memory modules of the same version or data code (D/C) from the same vendor. Check with the vendor to get the correct memory modules. • 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. Chapter 1: Product Introduction...
