Q: I'm using the Core 2 Duo E6XXX CPU and DDRII 533/667 RAM on 775Dual-VSTA motherboard. But the system is very unstable. Sometimes it gets blue screen or fail when installing the Windows® XP or some applications. How do I fix this problem?(2006/9/19) A: Please refer to following steps to fix this problem.
Please set the "DRAM Frequency" as "[333MHz (DDRII 667)]" in BIOS setup if you use DDRII 667 RAM. (BIOS/ Advanced/ Chipset Configuration/ DRAM Frequency)
Please enable the "Flexibility Option" in BIOS setup if you use DDRII 533 RAM. (BIOS/ Advanced/ Chipset Configuration/ Flexibility Option)
If the problem still remains, please update the BIOS to P1.80 or later version.
