You may install varying memory sizes in Channel A and Channel B
The system maps the total size of the lower-size channel for the dual-channel configuration
Any excess memory from the higher-sized channel is then mapped for single -channel operation
Due to intel spec definition . X.M.P. DIMMs are supported for one DIMM per channel only
According to Intel spec. DIMM voltage below 1.65 V is recommended to protect the CPU
According to Intel CPU spec. CPUs with a core frequency of 2.66 support the maximum DIMM frequency of up to DDR3 1333
To use DIMMs of a higher frequency with a 2.66 CPU. enable the ( DRAM O.C Profile ) feature in BIOS
Refer to section 2.4.1
Always instal DIMMs with the same CAS latency.
For optimum compatibility .we recommend that you obtain memory modules from the same vendor
