I bought a MSI Z77A-G43 and 1st PCIE(3.0 I guess) slot doesn't work?

I bought a MSI Z77A-G43 and 1st PCIE (3.0 I guess) slot doesn't work? I mean when I put my gf card in it , my screen wont start. BUt when I put it to other blue Pcie (2.0 I guess) it works. What will be the reason? Do I need to do anything in bios ?

I had a similar situation recently.
1.) Check the cpu/ socket for damage
2.) Remove the mobo and make sure there are no extra stand off's under the board.
3.) Check the pci/e slot for obstruciton or debris
Other than that it's probably going to be an rma issue.

  • MSI Z77A-G43 and mixed drive types

    Hi,
    I have an own-built desktop using a MSI Z77A-G43 motherboard. The OS boots from an SSD but all documents, media, etc, are stored on 2x1TB HDDs, configured as RAID.
    However, having performed a benchmark on my SSD I'm finding that it's speed is half what it should be. It's connected to the SATA 3 connector on the MB.
    I'm wondering if the issue is that, because of the RAID drives, I have the SATA mode as RAID in the BIOS. Is it falling back to IDE for non-RAID drives? Is there a way to force it to use AHCI?
    Any thoughts/help on this would be greatly appreciated.
    David.

    Well, checking you manual will clear up your confusion. SATA 3 is the connector number while SATA III is a terminology for SATA 6GB/s. Some say just SATA 3 meaning SATA III but that's just wrong terminology. The SATA 3 connector and all others but SATA 1 & 2 are 3GB/s (1-22 of the manual by the way)

  • MSI Z77A-G43 - extreme memory profile problem

    Hello everyone,
    I’d really appreciate a piece of help here. I’ve bought the MSI motherboard MSI Z77A-G43 and currently I’m having problems with my memory (slots 1 and 3). My PC has following specs:
    -   MSI Z77A-G43
    -   Intel Core i5 2500K (not overclocked)
    -   RAM Patriot 2x4GB DDR3 1600MHz CL9 (PGD38G1600ELK) G2 Series
    Everything is set to default values and works fine. But when I enter the BIOS, I see that the memory is automatically set to 1333 MHz. The memory has the XPM. But when I set the XPM (agressive timing, 1600 MHz) support (no other changes) and reboot the PC, it doesn’t work (endless reboot looping). Is there any way how I can make the XPM modus work? The memory is OK (tried on other MBs, XPM without problems), the CPU too. I tried overclocking, with slightly increased voltage I can easily reach 4,8 GHz on CPU, basically everything else is fine. The PSU is also sufficient (700W, OCZ). I can too set the memory on 1600 MHz manually, but the timing isn’t that good.
    It’s actually a failure I can live with, but since it’s a brand new PC, I’d like to get the best out of it.
    Many thanks
    V.K.

    Sometimes manually setting them works when XMP refuses to.
    I don't know what the XMP SPD profile for that memory is, and a screenshot of your SPD and memory tabs would help.
    However try the following.
    Disable XMP and reboot so they are back at 1333.
    Manually set it to 1600 and ensure manual setting of the timings to 9.9.9.24 see if that works.
    If not set your DRAM voltage to 1,575V and see if that works.
    It may be that your memory requires 1,65V, in which case, that is what you have to set. You should be able to see that in CPU-Z SPD tab under the XMP profile column.

  • MSI Z77a G43 boot loop

    Hi,
    I have read all issues about boot loop problems, but nothing fit mine.
    I bought MB MS Z77A G43 and Core i5 3570K. After building it, the computer is restarting again again.
    I clear the CMOS, boot and in the monitor it says, that setting was reset to default, it shows my CPU,RAM,HDD etc. and it gives me 2 choices:
    1) Press F1 to run setup
    2) Press F2 to continue.
    I tries several times both option, but after pressing the button F1 or F2, the computer starts to boot loop again. I cant go to the bios. Dont know if the problem is CPU or MB. I tried another power supply, but it didnt solve it. Any ideas?
    Thx for helping

    Hello again,
    I have change CPU and MB for the new ones, but problem still occurs. I found an information on the web, that i5 3570k supports only RAM with power consumption max 1.5V. I have Zeppelin DDR3 4GB kit (2x2GB) 1600Mhz, but when I clear the CMOS and boot, the MB says that I have only 1333Mhz. That means the RAMS has more then 1.5V?
    What do u think? The problem is RAM, which are not supported by CPU?

  • MSI z77A-G43 C1E enabled and strange noise from cpu area ?

    MSI z77A-G43 C1E enabled and strange noise from cpu area ? What will be the problem? When I disabled it there is no sound. BUt when I enabled it there is a strange noise while moving my mouse cursor or when there is some CPU activity, sounds like a squeeking or scratching, a bit like hdd activity, but barely noticeable. It looks like it's coming from the area around the cpu socket, must be something on the motherboard. is there a solution other than just disabling it? I want to be able to make C1E enable but cant bare this noise so I have to turn it of....

    Sound like some electrical sound produced by current going through that area.
    Try contacting MSI support for more help.

  • MSI Z77A-G43-memory problem

    Hello
    I bought lately new cpu,mb and memory. When i turned it on it was still rebooting after few seconds after start. So i treid to put just one memory in slot. It worked but only if memory is in bank 3 or 4. In 1,2 computer is still rebooting. Also it works with two memory modules, but putted in 3,4 slots only. And just in single channel. I saw that many people have the same problem and shop service wrote them that it works like that. First You put memory in slots 3,4 and then in 1,2. It is strange for me. I don't have two another memory modules to check if this is true and I want to that it works in dual channel, not single. So, is this true or mb is broken?

    Hello. I have the same problem, except, I use 4 Dimms in 4 slots on my MSI board. I installed speaker on MB to see if there are any beep sounds during the booting, but all seems ok. The problem is the PC keeps still rebooting after about 5 sec. from the start. There aren´t any visual information on screen, since the start is so short. I tried to install dimms in 2nd and 4th slot first. Then to 1st and 3rd. In both cases the problem was still the same. When I put all rams in all 4 slots, the result is the same (restart for ethernity). The only way that goes is the PC runs with only 1 dimm in either 1st or 2nd slot. I tested all the memory modules and all of them work fine. I even tried this on a differennt mainboard from ASUS P8Z77-V LX. Now I tested it on MSI Z77A-G43. Both mainboards are new. There is a very slim change that both of them would be defective. Before I got MSI MB, I ran couple of days on the ASUS MB and everything was perfect, so I don´t think that CPU is defective. I even ran a few benchmarks on it. But I still don´t understand why can´t I run the system with all 16 GB of RAM instead of 4 GB in one slot. Please help me.   

  • 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...

  • Black screen at boot MSI Z77A-G43 with HD7850

    Do you see the same problem on bios 2.90?
    The Z77A-G43 seems the have difficulties accepting HD7xxx AMD VGA cards lately.
    It seems that the problem is gone. I thought of it being an ATI driver issue ~ but not even the latest didn't fix it. But since I flashed to BIOS 2.9 I haven't encountered the problem anymore. So I believe something is fixed between 2.3 to 2.9.
    However my problem was a bit different that the OP has.
    Oh, and I said this on other thread so I say it here too: MSI and Asus 7xxx cards haven't faced the kind of issues Sapphires are having. I'm so glad to my choice... as I almost picked Sapphire but then read comments on Newegg which weren't in favor for Sapphire.

  • Three beeps when booting new computer with MSI Z77A-G43 Mobo

    I just built this pc and pressed the power button. Nothing happens for a few seconds and then I hear 3 beeps from the PC speaker. It powers off by itself and opens again, with 3 beeps again, and repeats this until i press the power button to close it down forcefully.

    try each stick in slot 2 individually as you may possibly have a bad stick?
    if the first suggestion doesn't work remove the CPU and check the socket as you may have a bent pin in there causing the issue?

    Does anyone know where I can get one of these in the UK, everywhere I look it says out of stock/discontinued..... I mean everywhere
    I have no choice to get a z77 version of the motherboard as im running an i5 3350p ivy bridge which is a 1155 socket.
    any help or location of this product would help.... I wish MSI would just sell their stuff too.

    Thanks for the reply I did see that one but I was looking for the red and black dragon emblem one, its seem everyone of these I find is somehow discontinued.
    prefer the red and black as its goes with the colours scheme I have also matches the 2 msi GPU's I have, just wondered if anyone knows of a UK retailers of this version
    As a side note the blue and black doesnt look as impressive XD

  • MSI Z77A-G43 Realtek Audio Manager

    Hello,
    I just bought a MSI Z77-G43 motherboard and I did a clean installation of Windows 7 Ultimate 64bit and when it started up the audio was already working which is normal. Then I installed the basic drivers (chipset,lan,audio).(Ok just so you know the situation)
    Now the volume changes on the new Realtek software are working, but the EQ presets, Graphic EQ, Environment settings, Voice Cancellation and Karaoke settings are not working. So basically the whole "Sound Effects" tab is not doing anything to the sound when being adjusted.
    What could the problem be here ? (And how do I add a picture to this message, I have a screen shot)

    Yes it's a shame that one cannot just use Realtek audio drivers but have to use the audio program too. I have tried to extract and install only the drivers but it always wants the software as well. And I haven't find those driver only from nowhere without the software studio.
    That's why I'm using MS drivers, luckily, those work perfect with my 5.1 set up.
    If anyone knows where to get just the audio driver without the software please post link here.

  • MSI Z77A-G43 UEFI Overvolt+Intel Exteme Tuner Overvolt combo

    Hey all,
    I just wanted to run past you an experiment I did and I think worked.
    I currently overclock my i5-3570k with an every day overclock of 4.4 at no offset voltage and a benchmark overclock of 4.7 at +.14V - however my benchmark overclock isnt exactly stable.
    I noticed in Exteme Intel Tuning Utility There's a slider there for additional  mV turbo voltage.  I'm multiplier overclocking for my benchmark overclock with no power saving features and my voltage tops out at around 1.34V but when I add additional mV on Intel Extreme Tuner it goes to 1.38V.  It also made me pass my 3dmark at 4.7 which is hit-or-miss but now worked every single time and also passed IBT.
    Could this truly be modifying my input voltage on the CPU beyond the motherboard's limited offset mV overclocking?
    Is this super dangerous and should I never do it again?
    thoughts/opinions
    also obligatory 3dmark link

    http://www.3dmark.com/3dm11/5624604

    1.400v's on the CPU is the industry recommended limit for an everyday machine, so whatever way it gets there shouldn't make any difference.

    If not doing a 'Turbo' OC, I don't see the connection with mV turbo setting. If raising the mV on the Intel utility raises the voltage to the CPU, and it is confirmed, then it must work as you have described.
