Question
System reports 8GB(3.99GB usable) at 64bit OS with 8GB(2GB*4pcs)memory installed. And "Memory Remap Feature" is "enabled" under Advance Chipset of BIOS. 


Answer
Please make sure that you exact follow the instruction of the manual for plugging the memory modules in order first as defined by Intel.


The possible reasons may cause the memory size half reduction are, 
1.  
Memory Remap Feature need to be enabled for 64bit OS.
2.  Memory module not well installed on DIMM slot. 




Question
The network connection links down randomly and intermittently, how do I fix it? 


Answer
If you have got chance being encountered below symptom in a network environment with some certain hubs/switches , please check following solution for this symptom with Intel® 82578DC Gigabit Ethernet PHY.

Symptom:
Network connection links down randomly and intermittently. Connection icon will be disabled and pop up a message, “A network cable is unplugged” at the right bottom corner like Windows XP. The symptom just appears in a short time then link up again soon.

Solution:
1. Set the "Speed and Duplex" to fix according to hubs/swtich supported.
2. Suggest user upgrade Intel LAN driver to version 16.5.
