MSI Z97 Gaming 7 - USB Device Over Current

Hi everyone,
I just made my first gaming PC, using an MSI Z97 Gaming 7. Everything went well, all the wires are connected correctly, but when I boot the PC, and try the setup (by typing the F1 button), this message appears:
USB device over current status detected
and the PC shuts down after 15 seconds.
I tried to unplug the USBs ports of the Case, tried to unplug the battery for 15 seconds, tried to boot again but the problem was still there. I also inspected all the USB ports, and I don't see anything strange.
Is it possible that the mainboard is faulty? Is there anything I can do about it?
These are the specs, if they are usefull:
MSI Z97 Gaming 7
Intel i5-4460 @3.20
Gigabyte GTX 970
PSU XFX 650W XXX Edition
RAM 8GB HyperX Predator
1TB WD Black
256GB HyperX SSD
CM Hyper T4
I hope someone can help me

sounds like something is shorted,
USB ports damaged?
have you tried rear USB ports and different USB ports?

have you unpluged mouse and keyboard too? assume they are USB one too
else take out mainboard out of PC case and place it over non conductive surface, like wooden table
then retest
and do you have a different PSU to try too?

MSI Z97 Gaming 3 usb charge

Hello, I have an motherboard z97 gaming 3,
Is it possible to have a voltage 5v on usb ports when pc is shut down?
I want to charge my phone

Yes there is a way, tricky that turn on Wake up event resume by USB device under BIOS, but take the risk of your PC turning on itself lol. (Better un-check the "allow this device to wake up my computer" under device manager--your mouse and keyboard.)

MSI Z97 Gaming 7 USB always on

Hi - I've already spoke with tech support about this topic and they couldn't help. When I put my Windows 8.1 machine to sleep, my USB ports are still on. Is anybody aware of a BIOS or OS setting that can sleep my USB ports too?
Thank you

MSI Z97 Gaming 7 (A2 ERROR CODE)

Hi everyone, because I have a problem with my Motherboard MSI Z97 Gaming 7 is that when I turn on my PC after display the code 99 and 9C, remains suspended in A2. From what I've read, this code is for a hard drive failure. The system remains in A2 indefinitely code until the reset button is pressed PC. In the second restart smoothly enters the operating system.
My System Hardware is:
*MSI Z97 Gaming 7 (1.90 BIOS)
*Intel Core I7 4770K (NO Overclock)
*16GB Corsair Vengeance (2x8GB) Memory
*MSI R7970 Lightning X2 CrossfireX
*Crucial M4 128GB SSD
*Seagate Barracuda 1TB Hard Disk
*EK Custom Liquid Cooling System
*Generic All in One Card Reader
*LG DVD/RW Drive
*Corsair AX1200i Power Supply
Then I tell them what I have tried without success this problem.
* Update BIOS to 1.9 Versión (Latest)
* Update SSD Firmware to 070H (Latest)
* Change SATA Cables
* Change SATA Ports
* Reinstall Windows 8.1 in UEFI and Legacy Mode
* Test each Ram Memory Sticks
* Disconect internal USB Card Reader, Front Ports and Corsair Digital Link
* Test try another SSD (Kingston V300 128GB)
After trying all these things, the system is still hanging in A2 Error
Thanks for any help you can give me.

You could try your device 1 by 1 and see which one of it is causing the A2 issue
about this i already suggested the same:
Quote from: Svet on 23-April-15, 21:42:28
connected them one by one, and see which is causing this hang eventually
he said any one of them alone is caused this A2 when its connected:
Quote from: sebastianmancipe on 23-April-15, 21:49:10
Already perform this test with any 3 devices, SSD, HDD or DVD's the same.
Curiously hangs on A2 code when first turned not when restarted.

¿this version of BIOS where it came from? It is official? because they have not posted on the official website of the Z97 Gaming 7? as had understood the latest BIOS for this motherboard is the 1.90
its official, but beta bios and newer than your current.
try all other things 1st that people suggested you, leave bios flashing as last option

MSI Z97 gaming 7 + intel i7 4790k

Hello. I bought the M/B MSI Z97 gaming 7. While I don't know what version of BIOS firmware installed. And I couldn't check it, because I only bought the motherboard. I want to buy a CPU for this motherboard - intel i7 4790k. Latest firmware version for this motherboard specified on the official website is 1.8
- Updated the VBIOS and GOP driver.
- Updated CPU Micro code to support new Intel CPU.
- Improved Asmedia SATA device compatibility.
When updating the BIOS via M-Flash, please make sure that your USB storage device is recognized as a "Removable Device",
If your USB storage device is not recognized as a "Removable Device", please update the BIOS via MSI Live update under windows.
Maybe this will turn out, that this processor (intel i7 4790k) will not work for this motherboard because of outdated firmware, and flash card is not recognized so I can't flash the BIOS or through a flash card or through Windows ?

Quote from: 964758 on 23-January-15, 22:33:17
Dear friend. Another question. How you understand about version of BIOS firmware by serial number of motherboard ? B - (means BIOS), 14 (means version 1.4) ? Do I understand correctly ? I will be waiting for your reply
NO you have that wrong and I will explain it to you:
its based off DATE! you can work out roughly what it will have shipped with by just cross-referencing the manufacture date and the BIOS release dates and which one was available at the time!
here is how you tell when it was made from MSI: S/N: 601-7916-010B1406030678 that is the date code in RED (Format YY/MM/DD) so that puts your board as made at 14/06/03 so it will have the BIOS version that was available at that time!
Nichrome has made a slight Mistake here your board actually has BIOS version 1.3 installed (>> 7916v13.zip << 2014-05-23 BIOS version) out the factory from the date code as its a early 2014 - June board towards the begging of the month (1.4 was not out till the end of the month)!
your board Will still support the chip (i7-4790k) as its got the minimum BIOS version (1.3) for that CPU for it to work out the box with it!

New MSI Z97 Gaming 3 - very strange audio issues

(sorry for the long post)
Hi, I recently bought some computer parts from Newegg and built my first gaming pc yesterday, but when everything was finished setting up I noticed a major issue with the audio. Both the headphone jack on the motherboard and the headphone jack from the front panel connector aren't working correctly.
If I plug in my headphones into the motherboard jack, the audio level is REALLY low. Like, even if I turn up the volume to 100% it sounds like it's only at 10%. I looked through the volume settings for the headphones and didn't notice anything wrong. Then I tried updating my drivers with the cd and ran the live update utility, but nothing changed. Also, the audio will sometimes make distorted/static sounds when the music itself is loud, yet I can still barely hear the music.
The front panel jack is even worse! The sound is much more distorted/static-y when I plug in my headphones there.
I know it's not my headphones fault because they work fine on my laptop. Even if I plug in a different pair, I still get the same low volume and static.
I know the front panel issue is not because of the case. If I put the motherboard in an old HP case and plug in my headphones into the front panel on this case, same issue. (I know the old case normally works fine).
I even tried running a linux live usb in case it was something wrong with Windows. It still had the same issues.
My specs:
MSI Z97 Gaming 3 ATX LGA1150
Intel Core i5-4590
MSI GeForce GTX 970
Corsair Vengeance Pro 8GB
WD Blue 1TB
XFX XTR Series 550W
Windows 8.1 Pro
I would really appreciate some help. It seems like I've tried everything.

Hi
What is the BIOS version your board currently has?
Try without graphics card and with single RAM stick.
You could also try out of the case on non conductive surface like wooden table or motherboard box, and see if it works then. Might be something in either cases shortening the board.

MSI Z97 MPOWER MAX AC vs MSI Z97 GAMING 9 AC

I can't decide which motherboard to purchase.
MSI Z97 MPOWER MAX AC = 20 Phase, 1x Intel I218-V Gigabit LAN controller
MSI Z97 GAMING 9 AC = 16 Phase, 1x Killer E2205 Gigabit LAN controller
I'll be gaming, and having a play with overclocking, which is the best do you reckon, they seem practically the same otherwise?
Which one would you choose?

Cheers for the replies guys, I appreciate everyones opinions.
Been digging for some more info...

MSI Also Launches its Z97 Gaming Series / Z97 OC Series Motherboards
The Z97 MPower MAX AC is a notch below the Z97 XPower AC. It offers a milder 12-phase VRM to power the CPU, but one that draws power from a combination of 8-pin EPS and 4-pin CPU power connectors, and featuring a coolant channel through the VRM heatsinks. There's no PCIe bridge chip, but the board still offers three PCIe 3.0 x16 slots (x8/x4/x4 when all three are populated). Storage connectivity on this board includes eight SATA 6 Gb/s, and one M.2 slot. The rest of its connectivity includes ten USB 3.0 ports, 802.11 ac WLAN, Bluetooth 4.0, gigabit Ethernet, and AudioBoost audio with headphones amp and ground-layer isolation. The Z97 MPower MAX is the most "affordable" of the lot, at under $200. Its feature-set is more or less identical to that of the Z97 MPower MAX AC, except it lacks 802.11 ac WLAN, Bluetooth 4.0, liquid-cooled VRM heatsinks, and onboard OC fine-tuning buttons.
The Z97 Gaming 9 draws power from a combination of 24-pin ATX, 8-pin EPS connectors, and uses a 16-phase VRM to condition power for the CPU, which is wired to four DDR3 DIMM slots, and three PCI-Express 3.0 x16 slots (x8/x4/x4 when all three are populated, x8/x8/x0 when two are, and x16/x0/x0 when one is. 3-way SLI and CrossFire are supported. An EMI shield covers the rear-panel I/O, while another shields the entire onboard audio circuitry, and the NICs. Audio is care of a 100+ dBA SNR DAC, which an external headphone amp circuit, ground-layer isolation, audio-grade capacitors, and EMI shielding. Wired connectivity is handled by Broadcom's newer Killer E2205 gigabit NIC. Wireless connectivity is handled by an Intel-made chipset that offers 802.11 ac WLAN, and Bluetooth 4.0 connectivity. Storage connectivity is devoid of SATA-Express, but features eight SATA 6 Gb/s, and an M.2 slot. Overclocking features include voltage measurement points, and POST LED display. Expect this one to go for over US $200.
The Z97 Gaming 7 and Z97 Gaming GD65 are two different beasts, although they're in the same price bracket (around $180). The Gaming 7 features an all-PCIe expansion area with modern M.2 slot, while the GD65 features dated mSATA 6 Gb/s. The rest of their feature-sets are identical, even if their PCBs are not. You get a 12-phase CPU VRM, three PCI-Express 3.0 x16 slots (x8/x4/x4 when all are populated), eight SATA 6 Gb/s ports, AudioBoost audio, and Killer E2200 NIC. The story repeats itself with the Z97 Gaming 5 and Z97-G45 Gaming.
Barring the milder 8-phase CPU VRM, both are similar in features to the more expensive Gaming 7 and GD65, with the exception of two fewer SATA 6 Gb/s ports. At the entry level are the Z97 Gaming 3 and Z97-G43 Gaming. The two are designed for gaming builds with no more than two graphics cards, and offer some legacy PCI slots. The two offer AudioBoost and Killer E2200, but skimp out on the CPU VRM, featuring just a 6-phase one. Storage connectivity is consistent with those of the Gaming 5 and G45.

Msi z97 gaming 5 bios update help

Hello I recently purchased the msi z97 gaming 5 motherboard. It was working fine it came with bios version 1.0 and I wanted to update it. I downloaded the latest 1.5 bios from msi website copied to usb flash drive and flashed it using mflash. Computer powers on but black screen wont do nothing. I cleared cmos and battery and still nothing so I am pretty sure its bricked. I am going to store to exchange it for another one but I want to be able to safely update the bios without bricking again. I usually dont update bios unless needed but i need at least 1.2 bios to fully support the devils canyon cpu. Can someone please point me in the right direction? I read about the usb flashing tool in forum but also read that bios+me need to be flashed and I don't know if that program is up to date and will flash both files? I really appreciate it if someone helped thanks in advance.

Also does anyone know if it is dangerous to update the bios with a 4690k devils canyon cpu since it is not officially supported until 1.2? Is that why my first bios flash was bricked? I would hate to go and borrow another cpu just to update the bios but if I have to I will. Sorry for all the questions but I need to get my bios updated and I will not update it until I am sure of all these things. Thanks to anyone who answers these questions.

MSI GTX980 Gaming sometimes not recognized by MSI Z97 Gaming 9 AC

I have been experiencing a very odd problem with my new hardware.
Hardware
Motherboard: MSI Z97 Gaming 9 AC
CPU: Intel Core i7-4790
CPU-cooler: Scythe Mugen 4
RAM: G.Skill RipjawsZ F3-17000CL9Q-16GBZH
Videocard: MSI GeForce GTX 980 4GB GAMING 4G
PSU: Seasonic X-660 80+ Gold
SSD: Crucial M550 2,5" 1TB
Monitor#1: LG 34UM95-P
Monitor #2: Eizo Foris FG2421
OS: Windows 7 Professional
Issue description
The thing is that with 2 monitors connected the videocard is not recognized on a cold boot, but boots perfectly most of the time after a restart. In some cases a restart doesn't do the trick. I have even seen a couple of times that the monitor shows that windows starts and then the monitor loses the signal from the videocard before I can see the desktop (rare). With just 1 monitor attached the videocard is recognized. Als the IGP works fine, it's just the videocard that doesn't seem to be recognized when 2 monitors are connected (all combinations of DP, HDMI and DVI). When the computer has booted after one or more restarts and the videocard is recognized the computer works flawlessly, no problems whatever I do with it (desktop work, stressing hardware, playing games, etc.). Not a single sign of instability.
It's just the cold boot and sometimes the soft boot or restart that causes the videocard to not being recognized with 2 monitors connected.
What makes it really weird to me is that when the computer goes into sleep mode I can wake it up normally within say 10 minutes. But if I wait for let's say an hour the videocard is not transmitting a signal through the videocard.
When IGP is enabled the computer boots and windows loads normally (I hear the sound of the Windows login), although the monitors stay black when connected to the videocard. Then switching the connectors from the videocard to the motherboard shows me a normal Windows login screen, but the videocard is not visible in the device list. When the IGP is disabled to bootup sequence just hangs until a restart works and the computer boots normally with the videocard getting recognized and working properly.
Click sounds
I noticed the motherboard makes 4 click sounds when booting, like relays flipping. I think it has to to with distributing power to al the components, since it looks like components respond to the click by turning led lights on. But I have to say I've never come across a motherboard before that makes click sounds. Is this normal?
Tried fixes
- Replaced the RAM with 100% working RAM from my other computer (Corsair Vengeance LP CML8GX3M2A1600C9) -> problem persists
- Disabed XMP -> problem persists
- Replaced the PSU with another one (Cooler Master V550 Semi-Modular) -> problem persists
- Reinstalled the videocard physically -> problem persists
- Tried several combinations of connecting the 2 monitors to the videocard (all DP ports, HDMI and DVI) -> problem persists
- Replaced the videocard with a MSI GTX970 Gaming (connected with 1xDP and 1xHDMI) -> problem persists
Conclusions so far
The cause can be found in the videocard or motherboard (probably BIOS issue).
Who can shed some light on this issue?

Try all PCIE slots no luck? Does the black screen always happen on one certain monitor or both?
I tried both the first and the second PCIe slot. No difference except for the fact that in the second slot the card only works at x8 bandwidth.
Quote from: jotan.va on 24-November-14, 18:05:51
BTW - Did anybody try to remove the wifi module from the board and then test?
I didn't install the wifi module in the first place.
UPDATE
I returned the motherboard to the webshop I bought it from and sent my cpu, ram, psu and videocard (GTX980) with it so they could test it. They found out that the videocard is the problem. So now I have to send the videocard to the webshop it bought that from. However, I am suspecting that it's just a VBIOS problem and not some fault in the hardware itself. On the other hand, it would be very strange that MSI would release a videocard that cannot work with one of their own top motherboards, wouldn't it?

- I got no virus.
- Everything is connected just fine.
I hope you guys can help me out.
Kind regards,

May be your PSU being too weak or going bad (I doubt though). Although you have 9 fans.. maybe try disconnecting case fans and leave only CPU cooler ones to work?

MSI Z97 Gaming 9 AC - Intel Wireless AC 7260 module don't work

Hi,
Please help me, i started my new rig and the wi-fi module (that hard to fit in the mobo) don't even appear in device manager.
I already tried to dismount and remount the module on the motherboard with extreme care, no success.
Here is my rig:
Main Board: MSI Z97 Gaming 9 AC
Bios Version: 1.4
Video Card: R9 290X
Memory: 16 Gb Corsair Vengeance 2400Mhz
Processor Intel 4790K
OC: Not yet
Operating System: Windows 8.1 Pro 64
Please help me

Recheck your WiFi Bluetooth expansion module connection on the board.
Recheck your MB mounting in the case, i.e. errant standoffs. Perhaps test the board outside the case on a non conductive surface to ensure no potential short exists. Then retest with the WiFi plugged in.

DIMM 1/2 stopped working on MSI Z97 Gaming 5, help!

Hello again!
Today I was trying out a different cooler for my i7 4790K, I mounted it and everything worked fine, but results were bad, so I decided to mount previous cooler again...
And here were the problem starts. After I mounted everything back (exactly following guide like before, thermal paste etc all done) my PC would not start the system nor BIOS.
I wondered what could cause it, so just to check a possibility, I unplugged one RAM module from DIMM 2 (they used to work in dual-channel at 2/4 DIMMs) and it suddenly started BIOS and system up normally.
Following this tip, I unmounted cooler's fan, because it covers DIMM 1 to check if it would work, and doesn't matter what memory I plug in DIMM 1 or 2, it won't work Doesn't work with any combination, so I can't actually use dual-channel right now, as only DIMM 3 and 4 work at the moment (both or alone). Any module plugged in 1/2 slots doesn't work.
All I see is that temperature monitor on my MSI Z97 Gaming 5 shows 10-55, 10-55 all the time, jumpy temps, everything works, but nothing loads. Just black screen, nothing. I work with 3/4 slots in single channel right now.
What the hell could happen? Please help me with this!
Edit: Is that possible I could move a CPU from a proper pin so it doesn't connect properly with DIMM 1 and 2? My cooler moved a bit before I mounted it properly. That's only thing that comes to my mind right now.

MSI Z97 Gaming 7 PWM Fan setting question

Hello, right now I'm using Z87 motherboard from others vendor (as***k), and now I want to change my motherboard to MSI Z97 Gaming 7. But there's something that I want to ask first. When I'm using still using Z77 motherboard which is MSI Z77A-G45, I can set the PWM fan to change it speed automatically by change the CPU fan to auto in the UEFI. But in the Z87 I currently use I have to customize it in the UEFI, so that my PWM CPU fan change its speed as the CPU temperature changes, it can't be set to auto and I don't like it at all. Now that I want to change my motherboard to MSI Z97 Gaming 7, I'm searching the review first. And I'm seeing that it have similar fan setting with the Z87 motherboard that I currently use
I want to ask, is it possible that I can set the CPU fan setting to auto just like the Z77A-G45 I used to have?

Quote from: Abula on 19-May-14, 08:22:10
What you are seeing is mulitple breakpoints of temperature, as you do on your AsRock.
I own a Z87GD65, and in mine i only have 1 true breakpoints, which is the temperature in which you want the fans to speed up, according to the temperature of the cpu. I als did a build for a friend on a Z77GD43 and it was similar just didnt had the graph, as it has on the Z87GD65 nor the new one that you posted on the Z97 Gaming7, but what i see is more customization on the new motherboard, with 4 different breaking points, i see the same restrictions on the PWM %, increments of 12.5% as it is on my GD65, weather its worth it, personally i dont care, one is good enough for me, i usually just spin down my fans to the lowest i can, and set the breakpoints for the temperature i want my fans to spin up, if the temperature is reach they will increase gradually, defined by the max PWM % and max temperature, this two variables (that you can change) will make the graph with more or less inclination. In the new Z97 Gaming 7, seems the same just multiple breakpoints, meaning you can have different inclinations into how the fans react depending on the temperature, weather its worth it or not.... depends on the level of customization you want to the fan control, personally im fine with a single, but i can see people that could like having depending on their needs, personally what i would have loved though, is to give me 10% increments instead of 12.5%, or 5% would been better, but 12.5% just seems odd number imo.
Remember, MSI only has 2 true PWM fan headers, CPU_FAN1 and CPU_FAN2, even though all are 4pin physically the SYS_FAN are not true pwm fan headers, they are voltage controlled and have much higher restrictions than the real PWM fan headers. And remember that if you plug 3pin fans on PWM fan headers they will spin at 12V that its the voltage that its handled by PWM fans, so be careful what fan you plug into where to have control on them.
Hmn, so since Z87 MSI use that breakpoint system to control PWM fan, just like my asrock Z87. So there's no auto setting on your Z87GD65?
