    "ECS brushed away the flaws the P55 chipset has really as they simply went nuts while designing this motherboard. Spared no expense we spot two NEC USB 3.0 controllers, we get to play around with SATA 3 6G thanks to an additional Marvell controller, they added an extra PLX chip and tied it in to the DMI interface for a 4 extra PCIe lanes covering the bandwidth needs of the new fast interconnects over USB 3.0 and SATA 6G and then added an NVIDIA NF2100 chip which functions as x16 PCie lane switch chip in-between the x16 PCIe graphics slots, enabling 3-way SLI as an option in a 16:8:8 configuration.

    The P55H-AK is very nice motherboard that offers excellent baseline performance, and heaps of features for any purpose. ECS is trying to govern the competition with a more feature-rich solution that is reasonably priced if you bare in mind what you receive. The P55H-AK is attractive to look at. It certainly is impressive and amongst the fastest performing P55 motherboard we've tested to date."

    IMPORTANT NOTE:
    Please read the notes carefully before updating BIOS.
    1.Do not update the BIOS if the system is running fine. Unsuccessful BIOS flash may cause the system fails to boot up. The manufacturer is not responsible for any BIOS flash failure.
    2.Make sure your M/B PCB version number first, and then read the updated description & special note carefully to check if the new BIOS version patch pertain to your current problem.
    (How to recognize the M/B PCB version)
    3.Please DO NOT reboot system,unplug power supply and remove battery during BIOS update process.
    4.It is recommended to use the updated flash utility included in each BIOS download package.

    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. 





    * means validated by ECS at time of writing. Changes to component or CPU may produce a different outcome. The result shown is for reference only and is subject to change w/o notification.
