    Default New Gigabyte Z77 Sniper M3 + 2700K - Overclocking woes and weird voltage behaviour

    Hi everyone,

    This is my first post here but I'm hoping some of you can shed some light on the issues I'm facing. I recently purchased a Gigabyte Z77 Sniper M3 and a 2700K as Haswell did not impress with its performance and high levels of heat. I am not new to overclocking but this is my first Sandy/Ivy platform and my attempts at overclocking have left me extremely frustrated.

    I have read and followed numerous guides and troubleshooting tips but nothing has helped so far.

    Now I know what your thinking, "Your doing it wrong!" springs to mind. And I do hope that is the case as I am not looking forward to having to tear down my system again and RMA the board.

    My first issue is that no matter what setting I use in regards to CPU voltage, it never gets applied even under load. I have tried:

    Ratio: 45
    Turbo: Disabled

    Setting the vCore to a fixed voltage - IGNORED

    Setting vCore to Normal with an offset -or + - IGNORED

    What happens is that when i apply load to the cores, the vCore shoots up to 1.368, then 1.392 then finally settles on 1.440 which is way to high. This is regardless of any voltage setting I set in the bios.

    The second issue is that when trying to trying to use Turbo mode to overclock, my turbo ratios are completely ignored:

    Base Ratio: 35

    Turbo Ratio 1-core: 45
    Turbo Ratio 2-core: 45
    Turbo Ratio 3-core: 45
    Turbo Ratio 4-core: 45

    Turbo mode on Auto - IGNORED

    Turbo mode on Normal - IGNORED

    Setting base ratio to 45 to match Turbo ratio - IGNORED

    Using any of these settings only results in the CPU boosting to 3.5GHz under load.

    I've now spent 2 solid days trying to figure out what is wrong but now I'm beginning to think that the motherboard is faulty and I am just wasting my time. Please help!

    Thanks,

    Stuart

    EDIT: I also forgot to mention that this is with multiple different BIOS versions. I have tried F9, F10c and F10f. All exhibit the same problems. I cannot try any earlier than this due to a compatibility issue with my HD7950.

    have you tried applying the cpu voltage or offset through the 3d bios?

    oh and if settings wont save or stick try reflashing the same bios and re enter settings again,they should stick/save then

    3D Bios exhibits the same problem, but i will double check when i get home.

    The problem is not the values applying in the bios, that is fine. Its just the voltages themselves are not being applied at load. Its like its permanently stuck on Auto.

    Ive also noticed that if i reset my BIOS, the M.I.T. screen works fine and is populated with value. As soon as I change anything in the bios (not just voltages/OC), save and reboot the M.I.T screen is blank again.

    This only happens with F10c/F10f bioses.

    I read something about synchronising the bios versions across both chips. I have not tried this but could the versions being mismatched be causing these issues?

    I don't thinkso,its worth a try flashing both main and backup tho with alt and f10

    pretty sure its poor bios support for sandybridge cpu's on z77 platform

    Yeah I think I Waz is right sandy cpus only seem to shine in p67 boards and ivy in z77 boards. Yes they are supposed to be interchangeable but only at stock speeds. I believe it is a bios problem should be able to be fixed but who know when gigabyte will get around to do doing so.

    Thamks for the reply guys.

    From what ive been reading, z77 should be able to overclock sandys fine, some even reporting better overclocking than z68 boards.

    I will try syncing up the bioses and see if that helps, although im not holding my breath.

    Do gigabyte reps check this forum? If so how often?

    I was looking forward to this being my first gigabyte board, but at this rate ill be returning this for the gene :-(

    you might be right on other z77 boards clocking sandy well

    you could try emailing gigabyte uk directly and asking them about the issue,they do look in but not sure when or how often

    Quick update.

    Synchronising the BIOSes didn't seem to help at all, so I'm not pretty stumped with nothing else to try.

    I have also posted this thread on the official gigabyte forums and will get in touch with Gigabyte directly. If I get some answers, I will post them here :)
