    Two different sets of firmware subsystems.
    UEFI is meant to replace BIOS, so it more complex. BIOS is old, simple and more developed.
    If I would you, I would of wait a little before upgrading now. I see too many issues with Z87 boards.

    I see. I never saw UEFI yet, as my PC is still a EP45-D3L using BIOS, and I was already planning to upgrade this week. So what do you suggest, upgrade to another brand / socket / etc.?

    At least it have not BSOD for whole day and memory runs with XMP profile enabled.
    Thank you all for support!
    I am a bit perplexed by this. What kind of UEFI options did you disable? And what effect does switching to legacy bios have? Isn't uefi and bios just interfaces, your commands are the same either way?

    I suggest to wait, next chipset revision. By that time Intel fixes USB 3 wake-up issue and manufactures, hopefully, will fix all firmware issues.

    Not interfaces, but hardware abstraction layer.
    Basic Input/Output System (BIOS).
    UEFI is meant to replace BIOS. UEFI provides more functionality, it includes all Legacy BIOS functions and adds a lot of new..
    I am not saying that disabling UEFI is a solution for memory issues. It just happened to work for me.
    IMHO all memory and other issues people are having all because of motherboard firmware is not good enough.

    Yes, I understand you were just saying that it worked for you. How do you disable it, is there a function when entering BIOS at startup?

    Do the IV's (Z77) also have similar issues? I was really bent on upgrading and speeding my PC, until seeing the issues. Thanks again.

    Of course there are options in BIOS at startup.

    I've no experience with Z77. I would not go for Z77 at this point. Z87 gives your more SATA 3 and USB 3 ports.

    If you do go for upgrade just make sure or your hardware is on QVL.
