    what does it say in the tuner/voltage tab,it should show a slider with the current ram speed

    There's no slider for Memory there, "Power On" and "Target" fields are both showing 1333MHz.

    Which CPU are you using? Maybe your CPU runs at 1333 FSB. If so, then you'd have to overclock the FSB. Just by raising the multiplier will NOT work. But there is MORE risk involved in raising the FSB than the multiplier.

    So wazza300, thanks to your help I'm starting to get somewhere! :-)

    I've been testing with only two sticks and I'm getting 1600MHz in both BIOS start screen and in memtest86+ on one of the pairs. When I put back the other stick pair BIOS complains that its settings are no longer compatible with the current hardware and goes back 1330MHz.
    I'm continuing to test with different combinations to isolate the faulty stick.

    I thought I had found the faulty stick - one stick always brings down Memory Frequency to 1330MHz.
    But then in the middle of checking the remaining sticks the system rebooted and brought up the BIOS warning dialog about settings no longer compatible with hardware. And frequency down to 1330MHz again. Saving BIOS settings and rebooting brought it back to 1600MHz.

    Looking back in the Windows event log shows that the system has unexpectedly rebooted every 1-2 hours.

    At this point I am starting to wonder if the problems are due to the motherboard or the RAM. Can GA-Q77M actually handle 1600MHz memory, or memory with 9-9-9-24 timings?
    How can I find out which one is faulty? memtest86 overnight didn't show anything...

    (Btw, at one point looking at the BIOS start screen I *think* I saw the Memory Frequency briefly dip down to 624MHz and then come back up again, could it be a sign of something?)

    yes it can handle 1600mhz,32gb @1600mhz might be a different story so I would test with less 16gb and see if it remains stable at 1600mhz

    Ok, so I've done a lot of tests with two sticks at a time. One of the RAM sticks (#4) seem to always force 1330MHz so it was left out of these tests. The tests below were all run with the three combinations #1+#2, #1+#3, #2+#3.

    Tests with XMP disabled and Performance Mode = Normal

    Two sticks in lower bank:
    • Memory Speed is 1330MHz (not desired)

    Two sticks in upper bank:
    • Memory Speed is 1600MHz
    • On third reboot error message is given by BIOS (see below) and Speed goes to 1330MH

    Tests with XMP = Profile1 and Performance Mode = Normal

    Two sticks in lower or upper bank (same behaviour):
    • Memory Speed is 1600MHz
    • On third reboot error message is given by BIOS (see below) and Speed goes to 1330MHz

    It seems strange that I have problems with all combinations of the RAM sticks. Also considering the post here
    http://forum.giga-byte.co.uk/index.php?topic=12234.0
    that describes a similar problem, makes me wonder if it's actually the motherboard that is the problem?

    BIOS error dialog:
    Code:
    Boot failure detected
    The system has experienced a boot failure possibly due to incorrect configuration.
    Previous settings in BIOS may not be compatible with current hardware state.
    
    Current CPU Speed : 3492.93MHz
    Current BCLK : 99.79MHz
    Current Memory Speed : 1330.60MHz
    
    Load optimized defaults then boot
    Load optimized defaults then reboot
    Enter BIOS

    have you tried emailing gigabyte and telling them the issue? it could be a simple bios update that's needed if they can replicate the problem

    Haven't yet, but with these findings today it's probably time to contact Gigabyte.
    Thanks for your help!
