Z77A-GD65 and frontal USB 3.0 randomly disconnect

Hi i use on my case Enermax Hoplite ST the front USB 3.0 port that have a 20 pin usb 3.0 header cable to connect on my Z77A-GD65 MB, i use this port with external usb 3.0 feed powered enclosure hard-disk Samsung F3  - 3,5 " 1TB SATA  for back up .... randomly, without any reason, enclosure disconnect , why? i haven't this problem if i connect the enclosure on frontal usb 2.0 and even if i connect to REAR USB 3.0 port .... only frontal USB 3.0 have this problem ... why? any idea? maybe frontal USB 3.0 have less ampacity of rear USB 3.0, than disconnect my enclosure?
bye

Could be a problem with your Enermax case's front cabling. If you have another USB 3 front or rear connection bracket, then you could plug that into the USB 3 header to test.
Else you will have to check with MSI technical what the max amps are on the USB 3 header. Mine works just fine with a portable 500GB external portable drive.

  • Z77A-GD65 and front panel audio problem !!

    I have a Z77A-GD65 and a case CM 690 II advanced window, and i connected the front panel audio correctly in the right port, and when i plug my headphones in the front audio jack, there is no sound !!!
    Please help me !!

    Ok, i've did this thing, now works, but the sound sounds only in the right side of the headphones, and the sound is very very slow....
    which of the 2 audio header plugs did you connect to the mother board ac97 or HDaudio?
    have you connected the headphones to the rear pannel connector of the motherboard to see if its better?

  • Z77a-gd65 and evga 660ti pci question

    Hey folks,
    I have been updating/rebuilding a system and have gone with a z77a-gd65 MB with the evga 660ti graphics card.  My question is that when booting on the initial splash screen I can see that the system is using PCI 2.0 instead of PCI 3.0, is there something in the BIOS that I missed?
    What are the main benefits of PCI3.0 over PCI2.0.
    Rgds

    Flash the bios with the attached archive. (Full release version A70 + ME flash)
    >>Use the MSI HQ Forum USB flasher<<
    Use option 1 and point it at the compressed archive and it will prepare the usb stick for flashing.
    When complete, do a full cmos clear, then install the most recent ME 8 Drivers:

  • Z77A-GD65 and Radeon R9 290 multi GPU problem

    Hi
    I am trying to setup four R9290 GPUs on the Z77A-GD65 board and for the life of me cannot get it to work. Using Windows 7 64bit with 8GB memory. I have tried installing the cards from the CPU end and backwards. Using the latest AMD drivers (13.12). Using 1x to 16x riser cables not powered.
    I think the problem is either not enough power on the PCIE bus or Crossfire is not working.
    Can anyone offer any help please?
    Thanks

    Are you joining the Red Rockets? If not, this thread is in the wrong part of the forum. The mainboard is only rated and certified to run a total of 3 AMD graphics cards in Crossfire. It also depends on the CPU used. With a Sandy Bridge, only a maximum of 2 graphics cards can be used, 3 with an Ivy Bridge.

    I think the problem is either not enough power on the PCIE bus or Crossfire is not working.
    Nope! Only 16 PCI-E lanes in the processor. If you want 4 GPU's, get a pair of dual GPU nVidia graphics cards.
    Allocation with 3 graphics cards is 8X 4X 4X for a total of all 16 available lanes.

  • Z77A-GD65 and fan controls

    I'm considering buying MSI Z77A-GD65. It has the better Realktek audio chip and Intel LAN chip. But I need to know what kind of fan controls it has:
    1. What kind of fan headers it has? (PWM, voltage controlled, how many?)
    2. What BIOS settings it has for fans? Ie. What is the minimum duty cycle for manual PWM fan control? What other settings and modes?
    3. Are there any plans to improve the BIOS fan controls in later BIOS updates?
    This is essential thing for a silent computer. If MSI is good enough, I'll get it. Otherwise I have to consider Intel DZ77BH-55K.
    PS. I'm only interested in BIOS settings, not possible Windows software settings. I use both Windows and Linux so everything must be controlled from BIOS.

    Hi
    I just bought that exact board for the same reasons you are considering it. The only Z77 board in that price range with both Intel nic and the better realtek Audio chip
    The only thing this board is lacking is exactly fan control. But i knew this before i bought board. You have the standard CPU fan Auto setting, but that's pretty much it. (at least what i have found)
    I invested a few extra euros in Silent case fans. For CPU i use the Corsair H80 that has its own fan control anyway.
    So i ended up with a relatively silent PC anyway.
    The board is brilliant for OC, and in general a very good board.

  • 890FXA-GD65 and possible USB Controller related issue?

    Hi all - Been having a bad time of it with a new system build for a little under a month now.  Have tried to capture my "notes" below, any idea of a root cause?  Is anyone aware of known issues with the board; the board and Windows 7; the board and some other component(s)?
    My issue:  During Windows 7 x64 installation or startup, the system will freeze at the "Starting Windows" screen.
    My system specifications:
    MOTHERBOARD: MSI 890FXA-GD65  (BIOS ver 18)
    CPU: AMD Phenom II X2 555 @ stock speed  (HDZ555WFGMBOX)
    MEMORY: DDR3 1600 2X4GB G.Skill Ripjaws-X [DIMM1 & DIMM2] (F3-12800CL9D-8GBXL)
    VIDEO CARD: XFX Radeon HD 5670 512MB (HD-567X-YNF3)
    HARD DRIVE(s): 2 x Western Digital 500GB 7200 drive (WD5000AAVS)
    POWER SUPPLY: Antec NEO ECO 620C 620W
    Windows 7 x64 (Ultimate edition, retail)
    This problem has existed since I first built the system and is consistently reproducable.
    I am able to avoid the issue by disabling the USB Controller in BIOS prior to initiating the Windows installer.  This will allow me to proceed through Windows installation, but as soon as the USB Controller is enabled once again, the issue recurs.  Having to disable USB support is undesirable.
    I'm now on my second 890FXA-GD65 motherboard, having RMA'ed the first board after a fairly brief exchange with MSI tech support(2 replies, with the eventual suggestion of RMA for a faulty USB controller).  So I went through the RMA process with the online retailer, receiving a new board today.
    The problem is that the RMA replacement behaves in exactly the same manner.  Normally this would suggest to me that the problem may lie with one or more of the other components, but I've not been able to identify issues with any of them.  One obvious suggestion would be to try swapping out components, but my resources are constrained on that front - video card happens to be the only component for which I have a alternate that I can test with, actually.
    As far as troubleshooting investigation, here's what I've done/observed:
    1. Windows installation/startup will succeed if the USB Controller is disabled in BIOS.
    2. The same behavior can be observed with a Windows Vista installation disk as well.
    3. When loading Windows in safe mode, the last driver file loaded was disk.sys
    4. Memtest86+ (v4.2), repeated full passes reveal no issues with the system memory.
    5. While seeming that it would be an unlikely factor, I have swapped out video cards(to an eVGA 8800 GTS 320MB), but observed the same issue still exists.
    6. Running in a single DIMM configuration affected no change.
    7. Have disconnected one or the other of the hard drives with no change.
    8. The BIOS version installed is equivalent to the latest(and only) version posted on the MSI support site.
    So...any ideas on what's left to try?  I've done enough reading online to notice that I'm not the only person to have observed this behavior, but have yet to encounter any explanation of it nor a resolution.
    Any suggestions?

    Trying to catch the points that weren't explicitly spoken to by me in the last attempt:
    @Stu - Regarding testing with zero USB devices connected - this was done as part of troubleshooting and it has no observable effect, so I think that I can rule out a bad USB device being the culprit and I apologize for not making that clear previously.
    @Frederik - I've done a little more legwork on the memory item.  Troubleshooting, for the most part, has been executed with this memory set to run as DDR1333 @ 1.5V as that is what the board auto-defaults to(the kit is rated as DDR1600 @ 1.5V)  It was at the defaulted setting that I ran memtest86+ and no errors were reported.
    I've also just now made an attempt to run this memory as DDR1066 at 1.65V and still there is no change in results.  In my research on this specific kit, I have not run into accounts like mine - in the accounts that I have read regarding a poor experience with the kit, memory has either been been obviously bad, for which failures are reported in diagnostics like memtest. ...or, I suppose that there's also the random guy complaining about his overclock not working or the memory speed defaulting to the wrong value in BIOS. 
    Frankly, I don't want to battle any particular component and I owe no allegiance to this make of memory.  I do want to try to be objective, given that I'm stuck with these modules until I make the decision to RMA.  As such, I had read what info is available out there - prior to purchase, I hadn't noted so many reports of issues with this kit across a considerable sample size of feedback so as to cause me initial concern, or else I would have gone with a different kit/different brand.  Probably will do that anyways, next time, but in the meantime, I'm afraid of this being a distraction.  If both myself and this other person(drgan) had both been using the same memory kit, and thus it was more likely to be the common thread, I'd certainly be more inclined to this line of reasoning.  But since he's using Kingston and in the few other accounts of a system freezing on USB controller enabled status I've noted varied memory kit brands, it doesn't seem to me to be an obvious culprit.  But if not, then what's left to consider?  The other interesting factor to me is that the issue appears to be Windows-centric....but...

  • Z77A-GD65 and Intel Rapid Start -suddently a problem ?

    Greetings.
    Have been using Fast Boot with my mobo since I learned how to do it, and it has worked flawless. But suddently something annoying is begun.
    When power on with IRS active, it starts to load with black screen, but after about 5 seconds, the hdd-led turns off, and my monitor goes to sleepmode (no signal from graphic-card). It then just hold there for 15-25 seconds, then wake on again and boot to windows 7.
    At first I had an access-code to log into windows, and with this active the pause 15-25 seconds is after the screen to type password is on, but BEFORE I can actually type anything.
    What can cause this error?
    On a secondary SSD I have installed Windows 8, incl. Intel Rapid Start, and the error is ALSO there! So my guess is, that it is something in the BIOS, but I have not changed anything in BIOS (just the bootorder to start from either SSD1 or SSD2 (Win7 or Win8).
    Please help if you can. I have braged about my 10 seconds start to a friend, but when I showed it to him, I had this silly error, so instead of 10 seconds it took 33 seconds. It was so embarrassing for me

    Is the hibernation partition large enough? (= to the amount of ram you have installed)
    Since this worked for awhile, what changed?
    Did you install some new drivers, new bios or new hardware?
    Might want to update the firmware of the ssd's
    If you wish, you can try the newest bios: >>Beta BIOSes<< When used with the forum flash tool, it will update the me versions. Aftwards, you will need to re-install the me drivers.
    Yes, it has worked, so partitions is OK. The strange thing is, that I have not changed drivers (oh yes, a driver for my  Nvidia graphic card, but that was after the error began, and only in Windows 7), no new BIOS settings I can remember of, no new hardware. It just started this about a week ago without I have changed anything. I have tried to reset BIOS, and load an earlier setup-profile of BIOS (my OC-settings), but that did not help.
    Oh, BTW, I can't install Microsoft SDK tool as seen here:
    http://www.sevenforums.com/tutorials/177443-gathering-startup-shutdown-sleep-hibernate-reboot-trace.html
    It begin install, but suddently under install, it starts to uninstall again without any error. I have an idea, that this tool might show me what is going on when starting IRS, but that might be a mistake?

  • T60 USB Mice has random disconnect, needs to be plugged back in

    We have a bunch of T60's here, and we use Lenovo USB mice with them. What happens is, at any given moment, the mouse will stop working. The user just unplugs and plugs the mouse back in (Port Rep or directly into machine). This usually works, but sometimes requires the mouse to be swapped out. Then that old mouse will work somewhere else.
    It's a very weird problem, and was wondering if anyone has a solution? I did some reading up and found other people with this problem, didn't find much of a solution though.
    Any help appreciated, thanks.

    Try setting usb in bios - config - usb  to always on or powered and in device manager remove the tick on usb hubs allowing windows to turn them off.

  • Portabe USB hard drive random disconnects

    I recently purchased a Canvio 1TB portable hard drive. It occasionally disconnects itself from the computer, seemingly at random, without me touching the drive or cable. My old 320GB USB 2 hard drive, with a double cable, never does this. Do I just need a double USB 3 cable, or is there something else going on?

  • Photsmart C309 and error USB Disk Unreadable, please disconnect USB

    Since upgrading to Mac OSX 10.9.1, I get an error message on my computer screen that the disk I connected to can not be read.  On the printer window is a message remove USB device.
    I can actually scan a document and see it on my computer screen, but if I try to save the document and open it later or preview the document or send the document, it is just lines on a page not what I scanned.  
    I have looked for new drivers.  I have removed and readded the all-in-one.  I have tried a different USB cable.
    Are the two incompatible?

    Hi CaroWA,
    I understand you have a Photosmart C309 and that is having issues working with your 10.9 Mac. I'm sorry to hear this has been happening, but I will certainly do my best to assist you.
    When you upgraded to 10.9 did you do anything with your HP software, or is it the same software you had with your prior operating system? If it's the same software as before, that could be why you're experiencing issues. For the Photosmart C309 there is no HP software at this time, so you would have to uninstall any HP software and then reinstall the printer via the Apple Updates.
    Hope this helps, have a great weekend!!

  • Sneak Peek of MSI's Z77A-GD65 Motherboard :)

    Here is a quick sneak peek of MSI's Z77A-GD65 motherboard. The board is intended for the upcoming Ivybridge 22nm processor which I think will be out this end of April. CPU socket is based on LGA 1155, so current Sandybridge Processors such as 2600k, 2500, 2300, etc… are still compatible. Other than this, the chipset natively supports USB 3.0 and PCI Express GEN3 lanes which can do both NVIDIA SLI and AMD CrossFireX. Running one video card is at x16, two at x8/x8 and three at x8/x4/x4.
    With the release of MSI X79 motherboards a month ago. MSI introduced Military Class III Components. This consists of Solid Capacitors, Super Ferrite Chokes (better overclocking and power stability), Hi-C Caps and DrMOS II (higher power efficiency, double thermal protection). All these components have passed the MIL-STD-810G Standards giving the best durability, efficiency and overclock on MSI motherboards.
    Moving on, here is the Z77 of MSI looks like. Black and Blue color themed motherboard and I pretty like what they have done with the heatsinks. The layout is clean and finally they moved the OC Genie, Reset and Power buttons on the upper right portion of the board. Much accessible especially when you are in a TRI-SLI video card configuration.
    Some basic information on MSI Z77A-GD65:
    •Memory Support – 4x DDR3 DIMMs Support DDR3 2667/2400/2133/1866/1600/1333/1066 DRAM 32GB Max
    •LAN – 10/100/1000 Fast Ethernet by Intel 82579V
    •Audio – Integrated HD Audio Codec by Realtek ALC898. 8-Channel audio with jack sensing. Compliant with Azalia 1.0 Spec
    •SATA – 4x SATA 6GB/s Ports (SATA 1-2 Intel Z77 / SATA 7-8 ASMedia ASM1061), 4x SATA 3Gb/s ports (SATA 3-6 Intel Z77)
    •RAID – SATA 1-6 Support Intel Rapid Storage Technology (0/1/5/10)
    •USB 3.0 – 2x USB 3.0 Rear I/O by intel Z77 / 1x USB 3.0 Internal Connector by Intel Z77

    I was able to test the motherboard using an Intel Core i7 2600K. Well it seems for me that the Z77 is more better in overclocking compared than the previous P67 and Z68 MSI models. Voltages are quite accurate too. It wasn’t hard for me reaching a 4.8GHz overclock on the said motherboard.
    Below are two benchmark results using MSI Z77A-GD65 and the 2600k.
    So that’s it for my share Hope you liked it guys

    I wouldn't get too tied up in benchmarking unless that is what you are going to be doing with your computer.  The -gd65 is MSI's 3rd best z77 motherboard, but it is also a bit older and has more bugs worked out.
    One big strike against the gd65 is it's lack of a true hardware switch for it's multi bios. The -gd80 and mpower both have multi bios's with a true hardware switch, this come in very handy if you like to tinker and end up flashing bios allot or overclocking often where a corrupted bios is a possibility.
    Just out of curiosity, what are the first and second best ?
    So you say you never had issue of slow sata transfers ?

  • Z77A-GD65 Ethernet Problems "Network Cable Disconnected"

    I've been running a Z77A-GD65 and have been having network problems with the onboard ethernet. Every time I go to play a game online I'll play for about 10-15 minutes and I'll be disconnected. When I'm back on the desktop, my ethernet icon on the taskbar will show "network cable disconnected" even though everything is plugged in fine. Fiddling with the cable or changing the cable does nothing. Reboot the machine and it's working fine until again I play a game for 10 or 15 minutes and the same thing happens.
    First, the card was showing the wrong MAC address as specified in the MSI FAQ for this mobo. Performed the fix but the problem is persisting. Tried the MSI driver and the newer Intel one. One time I got a "Code 10" error as posted in another thread and again, wouldn't correct itself until I rebooted.
    This only happens when I'm playing games. Web surfing or downloads work fine and my connection won't be disconnected until about 10-15 minutes into playing an online game.
    I put in another discrete Intel network card and that worked fine. No problems. Same with plugging in a USB wifi adapter (my current temporary solution). Therefore, I'm thinking it's an issue with the onboard ethernet or driver. Anyone else with this problem or how to resolve it? Using the latest v10.5 MSI BIOS.

    Removing the Asus Xonar did not help.
    Re-flashed the BIOS as well using a DOS boot USB key instead of M-Flash. Readjusted all setting to default. Enabled/disabled "Network Stack" in the BIOS (what is this supposed to do anyhow? It's undocumented).
    Wiped all drivers for this network adapter and re-installed the current ones from MSI's website. No change.
    Noticed that the adapter would correctly run at gigabit full-duplex when set to auto-negitiate. However, it would drop down to 10mbps before it finally showed "cable disconnected". Plugging and unplugging the cable did nothing until I reboot, then it would work again... until I ran a game online and it would disconnect after 10-15 minutes of play. Ran the Intel cable test and it was fine (and the cable and internet has been fine when used in conjunction with another discrete PCI-e Intel card).
    Re-crimped the ends to be sure. Tested again and the cable connection is good. Yes I know how to crimp ethernet so please don't suggest anything being wrong with the cable.
    I've pretty well nailed down that it is an issue with the onboard ethernet. I've read on Intel forums about problems with this chip on Asus boards. Hopefully an MSI employee can point me in a direction that could help, or at least have the problem resolved in a future BIOS update.
