Z77A-GD80 Thunderbolt (7757) & Z77A-G45 Thunderbolt (7752) & Windows 8 issue

While running Windows 8 with either one of the motherboards, if you have an unknown "Base System Device" in your device manager, you will need to change a BIOS option (figure 1).
VEN_8086&DEV_1548
- Z77A-GD80 Thunderbolt (7757)
- Z77A-G45 Thunderbolt (7752)
Go into the BIOS > Settings > Advanced > Intel® Thunderbolt > Security Level > Set to "Normal Mode w/o NHI". Save and exit the BIOS. When you reboot, the unknown device will be gone (figure 2).
This is Intel issue, however there will be no impact in regards to usability, features, performance, or stability.

It can also be that Intel Smart Connect is now enabled by default if you flash the bios. So if you flash you bios and notice this, with the z77a-gd80, that could be it as well.

  • Z77a-G45 Random Reboots

    I'm having a difficult time trying to determine why my machine is so unstable. Under any load at all, and many times without me even working on it the machine will reboot. I'm happy to provide any details or additional information that may be needed.
    CPU-Z Results
    I've run the data lifeguard utility for my hdd. I've run bluescreen view to try and get a handle on it. I've run a repair on the OS more times than I care to admit. But still the problem persists.
    Bluescreen view shows a 124 which as far as I know has something to do with processor or memory? Maybe memory voltage?
    If anyone can help provide additional idea's I'm open to them.
    Thanks in advance.

  • MSI Z77A-G45 Thunderbolt - UNBOXED!!!

     
    Intel’s Thunderbolt Technology is seen usually in high-end motherboard models. But today MSI just released a more budget friendly Z77 motherboard with this feature in it.
    The “Z77A-G45 Thunderbolt” boasts features like Military Class III Components for quality and stability, OC Genie II which automatically boost your computer performance in seconds, Click BIOS II for easier and friendlier to use UEFI BIOS, THX TruStudio PRO which delivers the best audio experience, supports Nvidia SLI and AMD Crossefire multi-graphic configurations and lastly Thunderbolt which delivers 10/GBps of data and display transfers – in each direction, at the same time – using a single cable to connect devices in a daisy chain.
    Military Class III Components are seen around the CPU socket. These are the SFC and Solid Capacitors
    The layout of the board is pretty the same as any MSI Z77 SKU models they have to offer. VRM heatsinks comes with flat heatpipe for better heat dissipation and a larger heatsink for the south. 
    Three PCIEx16 slots for multi-graphic card configurations.  Single video card can run @ Gen3 x16 while if you are about to use two it will be @ Gen3 x8 x8 and lastly for three, it will be Gen3 x8 x4 x4.
    All of the ports are handled by the Intel chipset. Starting from the left, you have USB 3.0 then 4x SATA 3GB/s in black and in white are 2x SATA 6GB/s.
    The rear I/O Ports are pretty standard but with the additional of the Thunderbolt port which is located beneath the VGA port. The board also have SPDIF/Coaxial Ports for Digital Audio Output.
    Then you have the bundles in the package.

    Quote from: Bernhard on 29-October-12, 15:10:10
    Is there any testing report that will follow to show us what was achieved with this board ? i.e. your practical tests on using Thunderbolt vs USB3 ?
    Such a pity there is no PCI slot.
    Or a DVI connection.

  • Z77A-G45 Thunderbolt - Newer BIOS?

    Hi,
    Might be a dumb question, but can someone tell me which is a newer BIOS?
    I'm using this beta BIOS:
    https://forum-en.msi.com/index.php?topic=166102.0
    However, a newer BIOS by date appeared on the support site, but seems to be lower by version (but not beta).

  • Urgent need of assistance, MSI Z77A-G45 Thunderbolt Unknown problems

    Recently I have built my first computer, a desktop with the MSI Z77A-G45 Thunderbolt motherboard, an Intel core I5 CPU and a NVIDIA Ge-Force GTX 650 TI Video Card, and a 850W PSU (way more than what is needed). The computer worked perfectly fine for about a week, I did not initially order a Disc Drive because I figured I could install windows with a flash drive (which apparently does not work) so I installed ubuntu for a while (irrelevant to the problem) I ordered the Disc Drive and when it came in I plugged it in and the computer would not turn on, so I spent a while trying to figure out why it did not turn on when the day before it worked fine, eventually after basically disconnecting almost everything and putting it back together it worked. But it had no signal to the monitor. I have no means of telling if it is a UEFI/BIOS problem, a video card problem, or a CPU problem. All 4 LED's for the CPU phase are constantly on, when before when the computer worked fine it would only have the first phase LED blink, so I believe it might possibly be a CPU problem, though the video card is what controls the output for monitors so it equally could be the problem. For the motherboard I tried just about everything to reset it, everything, except flashing the BIOS (which I don't want to try unless it is the only solution left) I tried to clear the CMOS, took the BIOS battery out and put it back in again. Please help!

    I do not yet have access to another desktop in which to put my graphics card. I just tried reseating everything and still no signal to the monitor. The VGA port on my motherboard does not work, it never has for some reason, I did not get intel integrated graphics with my CPU, I am not sure if that is why the VGA does not work.

    Running stock, board is otherwise very stable (memtest and prime95 passed).
    About half the time, this board resets resuming from S3 sleep. I'm at a loss as to why. So far I've replaced the memory, switched PCIe slots, reflashed BIOS, set MB defaults, over/under volted CPU and Memory, and switched memory slots. In my current test, I've pulled the graphics card and am now running on the integrated GPU.
    My questions are:
    - if this holds, how do I determine if it's the card or the draw on the PSU (no other to test) from the card
    - anything else I should try before I purchase 2x the components (as I have already done for the memory)?
    Thanks!

  • Cyclical Reboot After Sleep - Z77A-G45 Thunderbolt

    Often times my computer will restart 3-4 times after resuming from S3 sleep. It is very stable otherwise (passed memtest and prime95). While recent, This is not my first build, but have not seen this particular issue before.
    Was hoping for some suggestions on where to start troubleshooting. I am running stock and nearly all default settings in BIOS. I assume this is a memory or possibly a CPU voltage issue, but not looking to re-invent the wheel if someone can point me in the right direction.

    Oh, I read it, trust me. This did not explain why it was rebooting when coming out of S3 sleep.
    Unfortunately, it did not help -- I had another reset this morning. Going to mess with C1E and Intel C-States next to see if that eliminates it.

    Thanks

    Voltage at 24 pin and 8 pin connectors are ok and under the tolerance as I saw here http://pcsupport.about.com/od/insidethepc/a/power-supply-voltage-tolerance.htm
    I will check the other rails.
    Hmmm... starting to suspect that the cause is something else.
    Missed the beeps in the past.
    This mobo (z77a-g45) never emitted a single one.
    Not even at startup when it was ok!
    Oh man!
    The computer was running well and then suddenly screen went black, no disks activity, no keyboard response, no video, no reset switch working. Fans continue spinning.
    Had to pull the plug to stop the fans. Then plug it again but no boot. Just cpu phase led 1 is lit, fans activity and nothing more. No welcome screen, no disks activity!
    I will try to test the ram on another computer.
    Any other clues?

  • Z77A-G45 start up-shut down loop with more than 1 stick RAM

    New Build, personal use and doing it myself:
    BOARD: MSI Z77A-G45
    BIOS:   *?* click-bios reports "E7752IMS V2.5", but "MS-7752 VER: 1.4" printed on board?
    PSU:      Thermaltake 850-watt Black Widow 69A 12v rail
    CPU:      Intel Core i7-3770K BX80667i73770K - Quad Core, 8MB L3 Cache, 3.50GHz, 77W, Unlocked, fan included, no extra cooler yet
    MEM:    Corsair Vengeance CMZ8GX3M2A1600C9B 2x4GB 1600 MHz, 9-9-9-24, PC3-12800, 1.5V
    HDD:    WD Blue WD10EALX 1TB, SATA 6Gbs, 7200RPM, 32MB Cache
    CASE:  Thermaltake VN770M1W2N Overseer RX-I Full Tower
    OS:     Win7 Pro 64-bit
    System bought as bundle including the 2x4GB Corsair RAM.  Assembly went well but took me a long time to make sure I had it all right.  Then, nothing happened at power-up, no lights or anything.  My first reaction was to replace the included Thermaltake power supply (700 watt 52A 12volt rail) - I disconnected all power to the unit and removed the original psu and, on a whim, I booted up with the original power supply outside the case and the lights came on with the psu laying on it's side!  Got the start-up and shut-down loop (lights up and spins all fans for a few seconds, then shuts down and repeats ad infinitum), which I was not expecting. Replaced the original power supply with the Black Widow (specs listed above) and got same shut-down loop.
    Started checking the memory sticks one at a time in DIMM2, each produced that shut-down loop.  Also tried with two sticks of Patriot Viper 3 PVI316G160C9K 2x8GB 1600 MHz, 9-9-9-24, PC3-12800, 1.5V (which doesn't appear on MSI's compatible list...but I had it handy) Then, With the last 8GB Patriot stick in DIMM2, I finally let it go through that shut-down loop 5-6 times out of frustration, and then it suddenly powered up "normally"!
    I took advantage and have smoothly installed Win7 Pro, and mobo drivers from CD, no glitches, USB working fine.  Then tested each stick - all 4 RAM sticks work individually in DIMM2, but the board will not accept a 2nd stick in 4 without that same shut-down loop (tried using either matched pairs).  Manual specifies using DIMM2 and 4 (which are the black ones) for dual channel.  Have also tried slots 1 and 3 (blue) with same shut-down loop results, no BSOD or error codes, not even any beeps.  Computer boots normally and runs Win7 just fine with one 8GB stick in DIMM2.  Also boots Windows and runs fine with one 4GB Corair chip in DIMM2.
    Have done CMOS clears and also re-seated the cpu and heatsink/fan, and all pins and board connections looked OK.
    Have some problem getting into the BIOS screen to look at things - seems to boot up so fast with a re-start that Delete key and F11 don't quite catch before Windows starts (8-year-old Logitech USB keyboard?).  Have to completely power down and start up to get into BIOS, but that doesn't always work either. System recognized the memory change to the Corsair stick, but the screen went by so quick I couldn't catch it to get into BIOS.
    Questions:
    1) I've searched this board and read for hours about similar shut-down loops problems, but either nothing seems to match my particular quandary or I don't know what to look for.  I don't understand what's happening with this shut-down loop - since all four sticks work individually in DIMM2, could DIMM4 slot be defective and I need to RMA the board? 
    2) I have not yet removed the board and tried to start it outside the case - could a short be causing the 2nd slot to malfunction?  Standoffs are built into the case but they didn't seem too low, and the amount of standoffs matched the mobo mounting holes wiwth nothing else protruding.  It's a really solid board that did not bend when being attached. It's also possible to look down behind the board with the front cover off and see that nothing is touching it.  Will breadboard it next, since I have to take it out, anyway.
    3) Where exactly is the Bios version printed on the board?  Click Bios reports version as 2.5 but appears that 1.4 is marked on the board.  Have done no updates of any kind, only thing I did was disable the splash screen so I could see POST (like I could read that fast...!).  Do I need to contact MSI to find out what Bios version actually shipped with this board?  It's OK if I got an older board with updated BIOS, but it's confusing when something different appears to be printed on board.
    Additional info:  Phase lights - LED is lit and all lights flashed at boot-up. CPU temp running for three hours idle is steady 37-38C, mainboard system temp 25C.  Went with a larger power supply because I intend to use Crossfire and more drives in the near future, but using onboard video for now.  System to be used for graphics/video processing with multiple programs running.
    I'm currently working from an ASUS M3A78-CM board with AMD Phenom 9650 2.4 GHz.  I've never dealt with an MSI or an Intel system before, and the Click-Bios is something new to me.  Alas, I'm not an expert, but I've followed the basic steps I knew.  What did I do wrong, overlook or just plain don't know?  I sure would appreciate another opinion before I give up. I'm amazed at the speed of this motherboard/CPU combo - it's probably more than I need, but I'm intrigued to figure it out.
    Looking forward to those opinions,
    Jilliebob

    Do this, and while it is in the open re-examine your cpu pins w/ a bight light and hd zoom or a magnifying glass.
    Thanks, xmad, I'll look at th CPU again tomorrow/next day under the glass when I take the board out.  I already checked them under magnification and was leaning toward a funky board, but it never hurts to re-check.  Eyesight is not what it used to be, for sure (I miss DOS, if that's a clue...).  Don't want to flash the BIOS if not necessary, since it runs Windows fine and everything works except that RAM.
    Bernhard, I don't have CPU-Z installed on that machine and don't want to install anything else until it's working normally.  I'd never seen Click-Bios before and just need to get over my initial suspicion of something new!  Also learn my way around it before I change anything.  I'd never encountered a board reporting a bios different than printed on it.  I've never messed with manual memory settings or done more overclocking than just a little exploratory and suprisingly successful nudge - if you could point me toward a  good basic explaination of all those settings, I could learn from there.
    Appreciate your input very much.   
    Have learned a lot just reading the threads here for the last few days.  This is the best forum I've ever encountered.  I'll report back - some suggestions in other posts resembling my problem ended with no resolution, and that's a shame because one doesn't know if it worked or not.

  • Z77A-G45 Live Update drivers different than websites (Also Intel has their own)

    (MS-7752) Z77A-G45
    Win7 64
    Why are there different drivers listed in Live Update 5 than what is listed on the website?  This is especially confusing with Management Engine driver because there are two separate drivers dated 2013-10-16 on the website in addition to Intel and Live Update having their own different driver.
    Some examples:
    MSI website:
    Intel Management Engine Driver 9.5.15.1730
    Intel Management Engine Driver 8.1.30.1349
    Realtek High Definition Audio Driver 6.0.1.7037
    Intel Smart Connect Technology Driver 4.2.40.2418
    Live Update 5:
    Intel Management Engine Driver 9.0.0.1310
    Realtek High Definition Audio Driver 6.0.1.6959
    Intel Smart Connect Technology 3.0.42.1767
    Should I just go 100% by the website (although Intel's are also different than MSI's site..)?
    Also, I'm currently on BIOS 2.9.  Should I update to 2.C0?  Is that one stable for overclocking?

    Quote from: Nichrome on 07-December-13, 19:42:57
    I suggest you uninstall Live Update ( I did so) because it f...k my drivers one day, and had to do fresh Win7 installation and even BIOS update which I didn't need before ..
    That sucks.
    I've never actually installed anything with it.  I was just curious to see which files it'd attempt to update.  I'll definitely uninstall it now though..

  • Z77A-G45 - Static sounds on USB ports

    (pls move to correct forum, srry for the :censored:up)
    Hi all,
    Problem:
    I recently bought a Z77A-G45 for my new rig. However it has static\electrostatic noise on the USB ports. Meaning as soon as i plug in USB speakers or my Razor Carcharitas headset (USB powered) i hear static noise of the insides of my computer. Normal 3.5mm audio output is without static, even when amplified via external amplifier.
    These noises are loudest while browsing or other internet traffic, however they are always present and start right after POST.
    Troubleshooting tried:
    - Different BIOS settings regarding USB
    - Even the problem also exist outside the OS, i tried different combination of drivers (beta & officia) for NIC & Audio
    - Check and measured all grounding (and checked for ground-loop)
    - Removed all hardware except for MOBO+CPU+PSU+RAM and disconnected everything external including front-panel, to insure my perhipicals are not causing the problem
    - Did a 10pass memtest
    - Flashed the latest stable BIOS
    - Separated all cables inside the case and grouped all power & data so no interference is present
    - Tried my old Spire 650 Watt PSU
    My build setup:
    - Coolermaster  CM 690 II advanced
    - MSI Z77A-G45
    - Intel i5-3570k 3.4Ghz (Ivy) (CPUID: 0306A9
    - Scythe Mugen 3 PCGH-Edition
    - Corsair 8GB (2x4 dualchan in sock 2&4) 1600-999 Vengeance LP
    - Samsung 840 Basic 256GB
    - Seasonic G450 Powersupply (80+ gold cert)
    - Sapphire HD7950 (+boost)
    Details MSI Z77A-G45:
    - S/N: 601-7752-040B1209097231
    - BIOS: V2.9 / 20130118
    Kindly help me troubleshoot to decide if my product is defect and need RMA, or if this is fixable.
    EDIT: as i also had the boot problem i just updated to BIOS A02 2.10, however problem still persists as soon as computer is powered-up, i honestly do think this is hardware related ?

    I also have an SSD I intend to use for acceleration via Intel Rapid Storage Technology (RST).  I plan to eventually plug this into SATA Port 1.  But I didn't get that far...
    I am not OC'ing - using Standard Mode.  The only change I made in the BIOS was to switch the SATA Mode to "RAID Mode".  I did this prior to OS installation, per instructions.  And during OS install, I loaded the Intel SATA controller, per instructions.
    OS install was unusually rocky.  First attempt failed.  Second attempt worked, but took longer than it should have.  After installation... crashing, instability, and BSODs.
    Checked Memory a couple times, via Microsoft's memory checking tools.  Also reseated all DIMMs, to no avail.
    After some amount of troubleshooting, I saw that my memory was being reported as: F3-12800CL9-4GBXL DIMMs.  I assume this is correct, and that the "Model" I bought (F3-12800CL9Q-16GBXL) just describes the whole package of 4 DIMMs.  However, the one thing that is incorrect is that the timing is reported in the BIOS as 11-11-11-28.  The timing specs on my RAM are 9-9-9-24.  Overriding this in the BIOS to those numbers (for TCL, tRCD, tRP, tRAS) did not make any difference.  Instability continued.  The memory speed and voltage seems to have been set properly to 1600/1.5V.
    The other thing to note here is that I just bought the MSI Z77A-G45 to replace an ASUS P8Z68 DELUXE/GEN3, which was experiencing the same (but less frequent) instability.  I've been using it for a couple months, and decided to try my luck with a different motherboard.  Only this one is worse.  The only components that were reused were the CPU and RAM (and optical drive, PSU, and Case, if that matters), and the only other thing in common was that I had both set up in RAID Mode.
    Thoughts on how I should proceed?
    Thanks in advance,

    Regarding the memory speed, I'm confused.  The maufacturer site (gskill.com/products.php?index=349) says:
    CAS Latency   9-9-9-24-2N
    Speed   DDR3-1600 (PC3 12800)
    Also just to confirm, to change the timing, I assume I change this in the BIOS, under DRAM Timing Mode, switch to "Link" (from "Auto"), correct?  And when I do this, it enables the "Advanced DRAM Configuration" section.  If I double-click that, I can specify 9-9-9-24 (for tCL-tRCD-tRP-tRAS).  Former values were 11-11-11-28.  I assume I leave all other fields at "Auto"?  What is the "-2N" in the CAS Latency description on the GSkill site?
    Here is the reason:
    They are real DDR3-1600, but that means CAS = 11 @ 1.5V
    Their XMP profile is buggy (in fact that's the DDR3-1333 profile).
    For 1600MHz with CAS = 9, they need 1.60-1.65V

  • Brand-new Z77A G45 not booting

    Hello all. Just started putting a new build together the other day, using the Z77A G45. When I went to boot it up for the first time, it gave me the "Military Class III" splash screen, with the prompts to switch to POST, start BIOS setup, etc. However, pressing any of the keys doesn't do anything, and it shuts down after about twenty seconds or so. The CPU phase leds all turn on for a few seconds after it's powered on, but after that only the first one remains lit.
    I thought it might be because it wasn't recognizing my USB keyboard, but I had the same problem even when I used the PS/2 converter that came with the keyboard. I tried clearing the CMOS, and it gave me a screen showing that it recognized everything plugged into the board, and prompted me to hit F1 to continue setup, which worked, but from there all I got was a black screen with an "underscore" in the upper left hand corner. Rebooting with only one stick of RAM didn't change the problem, and I've tried all the USB ports, with similar results.
    I'm thinking that the problem lies in the CPU being damaged during installation, but there don't seem to be any bent pins.
    Here's the build:
    CPU - Intel Core i3-3220 3.3GHz Dual-Core
    Motherboard - MSI Z77A-G45 ATX LGA1155
    Memory - Kingston Blu Red Series 8GB (2 x 4GB) DDR3-1333
    Storage - Seagate Barracuda 1TB 3.5" 7200RPM
    Video Card - MSI GeForce GTX 650 Ti Boost 2GB
    Case - NZXT Tempest 410 ATX Mid Tower
    Power Supply - SeaSonic 520W ATX12V / EPS12V
    Operating System - Microsoft Windows 7 Home Premium SP1 (OEM) (64-bit)
    Monitor - Asus VS238H-P 23.0"
    Any help or suggestions would be greatly appreciated.

    Try it without any ram, you should get a beep. If not it seems to be RMA time.
    This is not true depending on the board and bios version. Not all boards/ bios versions beep at all.

  • 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

             Samsung 840 Series 500GB SSD (Media/Backup)
    OS: Windows 7 64bit Ultimate

    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...
