MSI Z77A-G45 Can't maintain overlock

I'm having problems overclocking my system. When I enable OC genie it will run 4.2ghz all day np. Now when I reset default values, turn op the vcore and then adjust my CPU frequency I can achieve 4.5ghz quite easily. Run some benchmarks everything is stable no problem.
Now as soon as I shutdown my PC and start it back up it always fails, tries starting about 3-4 times and then decides the OC failed and then restores default settings.
But even when I only up the frequency a little let's say 3500mhz it still won't boot up after powering down. It seems like something is changed after shutting down and powering it up again.
How come manually it can run high speeds but as soon as I power it down and up it fails?
And how come OC genie can run 4200 and power up just fine.
Even when I mimic all values OC genie uses it still wont power up.
update:
I was a little to fast to say it will work with oC genie all the time. At the moment when I load defaults and then enable OC genie it works fine. But shutdown the machine and then start it again it will also fail with OC genie enabled.
So it won't overlock even 100mhz when shutdown, when booted up and resetted there is no problem and I can stabily run 4500mhz with high load np. What is the difference between a reset and a shutdown and start up??? This makes no sense.
I'm running the latest bios version.

Have you installed all of the drivers? I linked win 7 64-bit make sure to select the right one.
Could you post ss's of your cpuid spd / memory tab & bios settings please?
Edit: Did you make sure the memory is installed in the right dimms for dual channel operation it is dimms 2 & 4 which sometimes throws people off.
Edit 2:  Don't do this with an I5 2500k, use the multiplier only to increase speed. That cpu does not like that.
Windows & drivers are not the problem. As long as it boots I get into windows, but it will fail at the POST state. Memory is installed as decribed in the manual in slot 2 & 4.
I made some screenshots:
Between pic 1 and the last I changed dram timing to link, but on auto it will fail the same way. Everything is stock. It doesn't matter what I change as long as I don't change the cpu freq it will boot just fine. But god forbid I overclock 100mhz it will fail. But only after shutting down. Like said before I can turn it all the way up to 4500mhz just fine, just don't shutdown and try to boot it up again.
I also did a CMOS reset, didn't help either.

  • MSI Z77A-G45 can't install window 7 by raid 0

    I have a rig which:
    CPU: Core i7 3770k
    HDD: Two Western Digital 1 TB 7200
    Main: MSI Z77A-G45
    Power supply: 700W
    Ram: 32GB DDR3 1333 MHz
    *** VGA card: MSI Geforce nVidia GTX 660 Ti 3GBDDR5 TF
    After configuring BIOS to setup RAID 0, I was trying to install Window 7 on my 1.8TB ( which was summed of two HDD )
    But I got a problem about couldn't install the O.S on.
    ***And about the VGA, whenever I plug it in my mobo, my monitor shows black screen as it doesn't recognize the VGA card. What happen if I install window then add the VGA card later? Will it affect on my system later?
    And what should I do to install RAID 0 with my stuff? I appreciate all supports.
    Thank for read and answer my topic!

    The 660ti will require a bios update to use most likely.
    Is the system stable enough to flash? The forum flash tool included memtest, run this an so long as no errors or crashes, go ahead a flash to the most recent bios.
    >>MSI Downloads<< For full release
    or

    Make sure in you next post to include more detail on the raid set up error. What error? When did it fail?

  • MSI z77a-G45 Gaming 3770k overclocking?

    I just recently purchased the z77a-G45 Gaming mobo and a i7 3770k, most of my googling would leave me to believe that the 3770k can easily obtain 4.6Ghz with fairly low voltages like 1.16-1.20 vcore; here comes the question...in order for me to obtain some level of stability @ 4.6Ghz I must crank my vcore to 1.4150 with 100% cpu offset resulting in a 1.39 vcore in windows with a 1.38 vcore under load.  I have all power saving technologies disabled, pll overvoltage enabled, cpu vdroop offset set to 100%; my question is am I missing something with MSI boards as this is the first one I've ever owned or did I just get a very power hungry 3770k?
    General system specs
    MSI z77a-G45 Gaming MOBO
    i7 3770k CPU
    16Gb of Gskill Trident X 2400mhz memory
    Corsair HX850 Gold PSU
    MSI GTX 670 PE OC
    Cooled by custom water loop

    Alrighty, appreciate the info; gonna back down to 4.4Ghz as I can maintain stability with 1.275 vcore in bios = 1.26 in windows = 1.24 under load resulting in hottest core never exceeding 70...was really hoping for 4.7-5.0Ghz overclock when most everyone who reviewed this chip in the early days was claiming such great overclocks with such low voltage.  But I'll chalk that up to either misinformation or non stability checked overclocks, I guess I'm old school; cause if it can't hold up to a minimum 24hr pass of Prime 95 small fft's it isn't stable in my book.  Might consider delidding it in a year or so once the new wears off, I had my i7 920 for about that long before I lapped it into a mirror shine lol.  So based on my new information 3770k's on average overclock between 4.4-4.6Ghz and can require up to 1.4 vcore and higher past 4.6Ghz which is where you start to really become thermally limited on liquid as the Ivy Bridge's 22nm technology puts the cores to closely together in combination with intel's cheap ass thermal compound solution. Maximum recommended voltage for 24/7 shouldn't exceed 1.4 vcore without some kick ass cooling or a combination of delidded processor and kick ass cooling cause ideally you want your cores mid 70's and below...that about sum it all up?

  • Help with OCing my MSI Z77a-G45 gaming with i7 2600k

    Hi there its been awhile since ive done OC since my old intel e8400 and everything looks different now..i just recently bought a  brand new Msi Z77a-G45 gaming MB and i7 2600k for good deal and would like to push my limits on this setup

    my old rig Corsair H50 for now waiting on my custom built water cooling
    i know i tried using the OC genie to test out their OC setting which gave me 4.2ghz with 1.336vcore and friend told me thats kind of high for a 4.2ghz?
    any help will be good step by step. my goal for now is to reach like 4.4-4.5ghz until i get a better cooling system

  • MSI Z77A-G45 and Samsung 840 Series weirdness

    Ok so here's the thing
    about a week ago i decided that it was time to build a new computer with a Z77A-G45 motherboard
    put it together, installed windows 7 64-bit and everything was working just fine - for about 5 days -
    but then one morning when i turned on my computer it decided not to boot and just sat there with fans running with an A2 code at the bottom left of the screen
    i tried taking out the ram leaving just 1 in and moving it to different slots and trying a different ram block boots thinking it might be faulty ram,
    when that didn't work i tried removing the graphics card and boot with just the onboard VGA, reset the CMOS jumper, and even replaced that battery on the motherboard thinking the shop might have shipped an almost dead one, took everything apart and booted it outside the case on a glass surface to make sure it wasn't some sort of short
    but the only time it actually wanted to get past the A2 code was when i booted with only 1 of my hard drives, so  i started changing my drives around using various combinations of SATA cables and ports (luckily had an extra 5 SATA cables lying around)
    eventually i narrowed it down to it wanting to boot with 2 of my 3 drives but the 3rd one (a Samsung 840 series 500 GB SSD, that has no system files or anything fancy other then music, movies and a few games at the moment) getting it stuck on the A2 code
    so i set it up as an external USB drive with a SATA/USB converter i had sitting around but then it would get stuck on B4 instead if i booted with the drive connected
    however everything would work just fine if i connected the drive after the system had booted up (or even just unplugging and replugging it when it got stuck on the B4)
    once back in windows with the drive connected i ran all the diagnostics i could think of but nothing showed anything wrong with it
    (and the only thing i had done with the drive before it stopped wanting to boot was to defrag it)
    eventually i decided to copy all the files from the drive to a different drive and reformat it as sort of a hail-mary
    and to my surprise that actually made it boot up just fine
    so i moved it back inside the case as a normal drive just to make sure it would still work (which it did) and then moved all the files back to see if any of them were the culprit - that turned out not to be the case however
    it booted up without complaint with all the original files on it
    so now my question is why?
    what the heck is going on?
    did defragging cause some sort of data fault that caused the bios to not be able to read the drive properly or did i just buy a haunted computer?
    like i said everything is back in the state it was the day before it didn't want to boot and bios and been defaulted so it's not really an issue at the moment but I'd still like to know what's going on so i can hopefully avoid it in the future
    any answers or comments will be appreciated

    This is strange
    I have Z77A-G43, and have exactly the same problem with one 1GB sata drive, that works just fine in every other PC.
    In my case PC run into restart loop, but with same code A2 as yours.
    Strangest part was PC was restarting even if I put HDD into PCI Sata/Raid card !?
    So I am guessing here its not a hardware problem, but a software (BIOS) problem.
    Now whole pc with Z77A-G43 is at Service because of faulty DVI output (not working).
    Will try reformating drive, but need first to buy >1gb hdd to backup that one
    Drive is currently working just fine in this 10y old MSI PC =.=
    It seams they have stopped making things as they used to, this old mb is one durrable dog.
    which was the main reason I went to same company when in question was mb...

  • MSI Z77A-G45 Crossfire

    I am planning to buy the MSI Z77A-G45 motherboard. Only i see the manual say:
    Quote

    ■ 2x PCIe 3.0 x16 slots
    - PCI_E1 supports up to PCIe 3.0 x16 speed - PCI_E3 supports up to PCIe 3.0 x8 speed

    Can you tell me if this motherboard does fully support 16 lanes on both cards in Crossfire?

    No, it can't. It will switch to X8/X8 if using Crossfire. Due to technical limitation Z77 can't go X16/X16

  • MSI Z77A-G45 SLI

    Hi, guys. Can somebody say to me. Does SLI realy works on my mainbord MSI Z77A-G45? On the my mainboard I saw "SLI ready", on the official site MSI I saw SLI ready too. But in the Basic Specifications on the site MSI  I don't see "SLI". Please help me to find truth!

    Even the product site lists SLI also in Basic Specifications (http://www.msi.com/product/mb/Z77A-G45.html#/?div=Basic) as it says "SLI - Y" and Y means Yes.
    Overview also lists SLI: http://www.msi.com/product/mb/Z77A-G45.html#/?div=Overview
    So yes, Z77A-G45 supports SLI in a X8/X8 configuration using the Gen3 slots.

Now i was able to do this before (Had a stable 4.4GHZ with 2133MHZ RAM speed.. i'm not quite sure what's stopped me from being able to OC more than these stated values, however in ClickBIOS i can OC higher than i can in the BIOS menu on startup itself but the settings don't apply correctly

  • MSI Z77A - G45 - CPU multiplier problem

    Hi,
    I recently bought this PC:
    Intel Core i5 3570 k
    MSI Z77A - G45 - with BIOS V 2.5
    Seasonic S12II-620 620W 
    Corsair Vengeance Low Profile White 8GB (2x4GB) DDR3 1600
    Amd HD 7850
    My problem is following:
    If I change CPU Ratio (multiplier), in standart mode to 40x and leave CPU core voltage auto, it cause instability, even if use Cpu core voltage 1.25 V for ratio 40x.
    But that's not all problem. I could understand, why I cant OC my CPU, but this instability is even if I change multiplier to 30x from default 34x and this makes me uncertain.
    Now I will describe you that instability...
    OK so, when I change ratio to 40x or 30x it doesn't matter, it runs to windows successfully but after using windows something about 3-6 hours pc turns off.
    I also  discovered second problem by coincidence. If I hit F11 (Boot menu) , when I am starting pc and I have set ratio 40x or 30x, I can choose what I want to boot only for 10 secs and after that PC restarts by itself....
    But if I set default 34x ratio I can choose what I want to boot forever and pc doesnt restart.
    I know that boot menu is not some test of stability but it is very strange... Why If I change multiplier, it doesnt matter, if it is higher or lower then default settings it just cause instability ? :-/
    Thanks for help.

    Quote from: xmad on 19-August-12, 07:02:15
    I was just saying that the beta caused a vga problem, latest release the f11 problem so try the release prior to that, but if you got it working don't touch it! lol
    Are you still using the beta bios?
    No clue, we are just users like you are, just keep checking the website. You should report the troubles you had with 2.4 to msi too.>>How to contact MSI.<<
    Yeah iťs working now. As I said, I wanted flash older Bios 2.4, so for sure I click on restore defualts in bios (for sure before flashing) in that 2.64 Bios version...
    PC restarts and my graphic card started working =)...
    So now I am running on that the latest Bios as you refered mi (2.64 beta).
    I am running some test of stability on @ 4 GHz with 1.070 V (IBT,Prime,memmaxx,linx,cinebench,occt,super pi, 3d mark) temps are 62 C max...
    So I guess it's ok now =)
    At the end I have one question :
     My Cpu is now running on 40 x ratio all the time, there is no some underoverlocking ratio (16x etc.) when it's in idle. I was thinking the Ivy Bridge overclocking is overclocking of turbo only...
    I know It's detail, because I have good temps even in idle with 40x ration (33-39 C) but i want to be assured if it is ok.
    EDIT:
    And btw I didnť have 2.4 bios flash on, I wanted put them on... But before flashing my 2.64 beta started working right with HD 7850 as is wrote upper.
    I had Bios 2.5 before 2.64

  • MSI Z77A-G45 RAID Issue

    Greetings...
    Just got a new MSI MoBo and wanted to RAID1 my two WD Caviar Black HDDs. However, everytime I enable RAID and reboot it goes to a black screen with two "Z"s randomly placed in the middle. Once I get to the "black screen", it will only boot to that screen afterwards and needs a CMOS reset to fix. I have tried everything I can think of, but always get the same results. I have successfully installed Windows 7 on one of the drives with AHCI mode enabled, and have also had IDE mode work fine... but as soon as I enable RAID - black screen.
    Everything else on the board seems to be fine. Anyone have any ideas?
    SYSTEM:
    MSI Z77A-G45 mobo
    Intel i5-3570 CPU
    Coolermaster Hyper 212+ EVO
    8GB Crucial DDR3-1600

    2 x WD Caviar Black Dual-Proc HDDs
    LG DVD Super-Multi Burner
    Silverstone Decathalon 850W PSU

    FIXED -  Ended up reflashing the BIOS, which restored the RAID utility. BTW, my G15 keyboard would not register the CTRL-I to get into the utility... I had to use a PS/2 keyboard, which required a CMOS reset in order to recognize. Just posting this in case anyone else runs into this.

  • MSI Z77a-G45 graphics driver issue.

    02-june-2013
    MSI Z77a-G45 graphics driver issue.
    Trying to install the graphics drivers for this board from the MSI site, I but every time I do so on loading windows 7 my monitor just goes to sleep and I have to roll back the driver in safe mode. This is the same for the driver found in the windows 7 updates.
    Iv downloaded the files a few times over and reinstalled windows twice and the problem remains. Can anyone suggest anything? Is there something I’m missing or need to set in the UEFI bios for using the onboard graphics? 
    MSI Z77A-G45, i5-3570K, 2x 8GB Corsair memory, Windows 7 64bit.
    Thanks.

    My BIOS is E7752IMS V2.10
    Iv already downloaded  V2.A
    However  I have to say the guide at uk.msi.com/service/biosupdate/ , appears to be putting v2.2 on top of v2.2.
    it also says "Download the BIOS that matches your motherboard and version number to your USB device."
    I'm not entirely sure what is meant by 'version number' but it dose suggest i need to download V2.10 not V2.A ... call me picky but i want to be sure! lol.
    Can anyone confirm ether way? It dose seam rather odd!
    Thanks.
    **edit
    Update on my graphics issue
    With the default driver, just before the windows 7 log in screen appears. I was getting a portion of it appear first on the bottom 1/8 of the screen. Now its appears to be a snowstorm of bad graphics and its the same when I switched to using HDMI instead.
    Not sure if that's a good sign!
    For reff my screen is a HP LP2475w tho I'm rather sure there is nawt wrong with the screen.

  • MSI Z77A G45 boot loop

    Hi everyone!
    I just tried to flash my MSI Z77A G45 today from the bios version 2.1 to 2.A.
    I had blackscreens all the time when i tried to flash it with the M-FLASH utility from my bios.
    Then everything just started normaly (after each blackscreen), but there wasn't any update, i tried to force the update with LiveUpdate.
    And now when i try to start the computer, i just get a blackscreen (no signal for the monitor) and a boot loop.
    It just stops and reboot after 10s.
    My hardware is working perfectly, i think this is from a corrupted bios issue.
    Which things i tried:
    - Doing a clear CMOS (nothing happens)
    - Removing the CMOS battery for 10 minutes (the reboot loop stopped, but there was not any display, i restarted the PC then and the reboot loop started again)
    - Cleaning my PC (from dust and things like that), it was not efficient at all
    - Booting from a USB key with the bios in, and formated as FAT32, nothing happens too. It doesn't recognize the USB key and anything else (keypad etc.) so the blackscreen was there again.
    My Hardware:
    CPU: Intel Core i5 3570 3.4 Ghz
    Motherboard: MSI Z77A G45
    GPU: None (Intel graphics 4000)
    RAM: 2x4Gb Corsair Vengeance
    HDD: Crucial M4 SSD 64Gb
    Power supply: Corsair 850W
    Do you think that i need to send my mother board back to the RMA?
    I hope you will be able to help me, or find a solution 
    Thanks in advance

    You can try the steps found here https://forum-en.msi.com/index.php?topic=119375.0
    Otherwise, it is RMA time.
    Next time use the forum flash tool and archives found on the forums.

    MSI Z77A G45
    i5 3570k with Macho Hr 02
    Sapphire HD 7950 Vapor-X
    2x4 GB Corsair Low Profile 1600
    XFX Core 550W
    The problem is MOBO is not dectecting my HD7950 Sapphire when connect to HD7950 HDMI out (using SONY Bravia as display) It works only with integrated graphic on MOBO hdmi out. I've installed Win7 64-bit. System boots fine but only on i5 graphic.
    I'm using nearest CPU PCIe port. Unfortunately can't try plug HD7950 in with other PCIe port, Radeon won't fit in case I own (Fractal Core 3000 usb 3.0)
    BIOS version 2.9
    Need your help

    Has the VGA been tested in another machine to verify it works? Do you have access to other VGA's you can test in the primary graphics PCI-E 16X33 slot? If nothing works, then it can be a troubleshooting extravaganza! First recommendation would be to test outside the case on a plain piece of cardboard or untreated wood surface, barebones configuration. Inspect the case for any errant standoffs that may be shorting/grounding the PCI-E slot. The primary graphics PCI-E slot not working can also be caused by a pin problem in the CPU socket. A bright light and magnifier will be needed for socket pin inspection.
