Z87-G45 issue booting with USB devices in USB 3.0

Hi Guys,
I have windows 8.1 and updated all the drivers/BIOS. If I have anything plugged into my USB3.0 ports on the back the PC will freeze just after the dragon logo. Unplug it and all is fine... is there something I need to set in the BIOS to fix this?
FYI: I have the BETA BIOS that was suggested in another thread

I kind of hijacked a thread so made my own. I was going to RMA it but I brought a new motherboard (and my luck it had a dead PCIE slot) so I'm back to my MSI board.
I posted it in here : https://forum-en.msi.com/index.php?topic=174027.msg1267212#msg1267212
and this was my last reply:

Load up CPUZ and see what version the PCH is revision 04 (C1) or 05 (C2).
Mine says:
REV. 06
REV. C1
The weird thing is... if I unplug all the USB devices and boot then put them in again it works fine. But its massive hassle to move everything to do this.
edit 2: Think I will make a video and upload it to youtube to really show you wants happening. you can view it here:

Can Solaris 10 boot from USB devices like USB thumb?

1. Any live CD build for Solaris 10? That's the one which can boot up from CD and run immediately.
No installation requirement.
2. Can Solaris 10 boot from USB devices like USB thumb?

You can find "live" CD and DVD images at OpenSolaris site: www.genunix.org/distributions/belenix_site. This OSolaris version is booted from CD/DVD drive and can be permanently installed on HD drive. Moreover You can find at this site suitable script for USB thumb preparation. However You should remember that the number of read/writes on USB thumb is limited (ca 400 and slightly more in more expensive versions).
Good luck.

New Z87-G45 wont boot to windows - restart loop

I purchased a new MSI Z87-G45 Mobo and i5 4440 and now I cant boot into windows.
It was blue screening but now it just gets to windows load screen for a second and then restarts.
I have an older sata HDD would that be the issue?
I was able to install windows on a new SSD and it boots and works fine so its obviously something to do with the older HDD.

you can't boot from older OS installation on new different mobo

Z87-G45 Gaming - Boot error code A2 (stalled)

Hey folks,
I just purchased this board with an i5-4670k
I have a weird issue with the boot process. It doesn't occur at bios default values, only when I change them.
Here is the steps I do prior to get this stalled on BIOS load screen
1- I change the OC settings to get to either 4.2 or 4.4GHZ (1.29v for CPU 4.4ghz and 2v for input)
2- hit F10, save and restart
3- Boot normaly into windows.
4- Launch AIDA64 to stress test the system for 8h. Yes I did the 8 hours at first. It successfully passed the stress test.
5- I browsed a little bit.
6- I played battlefiled
No issue so far.
7- I shutdown the computer.
8- I then restarted it, and BOOOOMM. It stalls on the black screen, prior to the Dragon screen, with a A2 code in the lower right corner.
So I know the the OC is fine, since the stress test is OK for that long. I tried it several time, but only stressed it for 30min, then reboot and BOOMMM again. :/
So can someone, from MSI, help me?
Thx

Hey!
I decided to chip in since I have almost the same issue.
My PC boots to Windows and runs just fine apart from the 2second A2 debug code delay. Been playing games like BF4 for a good amount of time etc.
I just seem to be getting that same A2 debug code whenever I boot, seems to be the WD Caviar Red drive I just bought a week ago, already tried a few different sata and power cables, which dont help the case. When I unplug it the boot happens normally without any debug codes. Thing is the HDD seems to be working just fine, tested it with HD Tune Pro and CrystalDiskInfo. Also im not certain, but pretty sure that the A2 debug code only started happening after I installed a GTX 770 (day after the WD 1TB Caviar Red drive). Then again that doesnt make much sense? Since then it would most likely be an issue with the PSU, but seeing how I can play BF4 on high settings for 2hours straight it most definately isnt I think. My problem doesnt have anything to do with overclocking though, since I run everything on default.
Any ideas? And again, sorry for chipping in your thread. Just saw the same debug code problem and thought I shouldnt do a new one.

Expresscard issues X230 with Startech 2 port USB

Just bought a 2 port flush mount 54mm USB expresscard (Startech.com) and it does not see any USB devices I plug into it. I installed the drivers from the CD and from Startech site and device manager shows drivers installed correctly. To me, it appears there is not enough power to drive my thumb drives etc.. Everything seems to be installed correctly but just does not work. I'm thinking there may be issues with the expresscard slot.

I had difficulties in chosing the right ext disk, as so I contacted WD support For my device the compatibility list of ext WD disks spans from all WD My Passport and Elements Portable series (
http://www.wdc.com/en/products/external/portable/) so I bought an Elements 500GB and it prfectly works Thanks Tony

Msi z87 g45 infinite boot loop

Hey everyone, i just purchases all my new components including msi's z87 g45 motherboard. When trying to start the computer it turns on one second and then off again, and that goes on until i turn off the psu. I tried a lot of things like different RAM sticks and different dimms, and even with only the cpu and psu attached to the motherboard it still does the same:( Now ive read a lot of things, but at another forum i read that the i5 4670k is only supported by a bios v1.1 My g45 motherboard says it has v1.0... So cud that be the problem or shud that not matter? suggestions please :(
My system:
i5 4670k
z87 g45
xfx pro 650w
crucial ballistix 2x4gb
msi gtx 770 lightning

Clarify what board you have. Is it Z87-G45 GAMING? If so it lists 1.1 is required indeed. None the less it has been released with Haswell and the first release Haswell cpus (like 4670k) should be supported with any bios out of the box (even 1.0). I doubt that bios version could be the problem as it would be impossible to flash then as there is not even any older cpu that is officially supported with 1.0.
Try reseating cpu and check socket for bent pins. Also try running board outside case with just basic components.

Installing Windows (Boot) with Ipod as an usb hard disk

hi
i want to use my ipod to boot and install windows
to select him in the bios boot sequence as usb hdd
plz help

First, BIOS must support a boot from USB device. Second, iPod must be in Disk Mode. Third, iPod must be formatted as bootable medium such as floppy diskette, CD/DVD-ROM, or flash drive. Let us know when and how you accomplish the third part.

24" iMac AlSiO does not boot with iPod video on USB dock

Hello all,
I have already reported this as an issue with Apple.
I noticed that when I turn on my new iMac with the video iPod on the dock connected via USB, I only see the gray screen and the OS does not start. However, once I remove the iPod from the dock, then the Apple logo will show up, and the circular moving tiny line counters will ensue before the login screen appears.
Just wondering if anyone else is running into this problem.

Thanks for the suggestions den.thed and elmac.
I have done the following:
- Selected the Mac OS X on the MacHD as the startup disk and locked that from further changes. Restarting the iMac did not work.
- Verified and repaired permissions. Restarted the iMac and it did not work either.
In addition, I also tried:
- Restoring the video iPod and leaving it without contents. Rebooting the iMac worked.
- Syncing iTunes with the iPod after the restore. The rebooting problem appears again.
It seems like some synced items on the iPod are causing the issue as odd as that sounds.
I did not have this problem with my G5 iMac.
Since there is a workaround, I'll just live with that for now.
Thanks again.

Z87-G45 Gaming boot order changes itself causing boot problems

Okay so I got this new motherboard and everything worked fine yesterday.
But today when I tried to boot it couldn't find the boot.mgr so I looked from were
it tried to boot and it was my SSD were my games are located and it should be my SSD
where my system is installed, so I changed it and it booted right up with no problems.
then I just maked sure everything is okay so I restarted my pc and same thing only then
when I wanted to change the boot order my System SSD was gone So i restarted and
there it was again, so again I changed it and it booted right up and again I wanted to make sure it
would boot again when I restarted and.. well no it didn't and now it was my HDD which was my first boot
order so I have no idea what this mean and how I can solve this

Did you install your windows system using UEFI method or just the standard legacy mode?
If standard legacy mode then your first boot should be set to your HDD, and if you still can't get in the Windows,
try to plug the SATA cable and connect it again, also make sure that it is not your SSD itself that have problem,
cause i got Samsung 840 SSD before and it's causing many weird issues, sometimes even don't let me go to windows mode https://forum-en.msi.com/Smileys/msi/undecided.gif

Will Z87 GD65 Gaming boot with 4790k in order to update BIOS?

So, I have a Z87 GD65 Gaming motherboard.
I was planning on buying a 4770k cpu, but changed my mind to 4790k. The motherboards supports 4790k in the last release of BIOS.
Do i have to buy a supported CPU (or send to a local store) to update BIOS or can I boot directy with the 4790k and update?
Thanks.

board needs to be at least at bios 1.9 to even post with a Haswell refresh cpu. While 4790K is officially supported with the later bios 1.A it should at least post with 1.9. Therefor a boar manufactured before 2014-02-24 will not work out of the box with a 4790K and a supported Haswell cpu to flash or update by a shop will be needed to use the cpu.

Z87-g45 not booting, no display

Hi, I'm building a new PC (as the motherboard went on my old one) with the components listed and it refuses to boot.
The fans and lights are all coming on.
I have disassembled and reassembled it.
I have tried starting it without the gfx card.
Without HDD
And just now without any ram whatsoever.
At no point have I seen any display on screen or heard any beeps.
Judging from other posts I was expecting to hear beeps when I tried to start without ram at least.
Any help diagnosing the problem would be greatly appreciated.
Sorry if I'm a bit terse I'm using my phone

Try a bare bones set-up with a single stick of ram installed into the 2nd DIMM from the cpu.
Then switch sticks/ try different DIMMS.
If all fails, remove the cpu and inspect the cpu socket pins for any even slight damage. Use a bright light and magnifying glass and if necessary correct the problem.

Z87-G45 not compatbile with U14S using all 4 DIMM's?

So after installing the U14S, the fan is touching the 1st RAM heatsink. Isn't the U14S suppose to be compatbile? Am I doing something wrong? If I try to squeeze the ram, it is visibly pushed (the space between the 1st and 2nd is smaller than the space between 2-3-4th ram)

most people with that cooler and RAM have the fans reversed so one is on the I/O side (flipped around as a pull) and the one in the reversed! so technically it will work but not in stock fan layout!
How is that making any difference? The thickness would be the same
Quote from: Bernhard on 02-May-14, 05:58:58
Is that low profile RAM?

I'm thinking I might be trimming the fan since it looks like 2 more mm's should do it. What's the best tool to trim the plastic?

Z87-G45 all USB ports stop working until I reboot

Hello everybody, This is my first post on these forums due to this problem, and I hope some people can help me out.
In February, I purchased myself a Z87-G45 motherboard along with all the other components needed to build a gaming PC, the build went brilliantly considering it was my first time!
About 3 months into my new build I started having problems with my PC, especially my USBs directly connected to the motherboard and the ones at the front of my PC as well, I have a back lit
keyboard and mouse and the lights started flickering erratically like it was being connected and disconnected extremely quickly, then after about 10 seconds of it doing that, they both stop working.
The lights on my mouse completely go out as if it had being disconnected but the keyboards lights are still on, but none of the keys work.
Sometimes I can do a 6 hour gaming session with my mouse or keyboard not playing up at all, but other times it happens within 5 minutes of booting up my PC!
My PSU failed at one point, and when I used a lower power PSU until my replacement came, none of these issues occurred.
I really want to get to the bottom of this because I cannot game while my peripherals are cutting out mid game!
My specs are:
Intel Haswell i7-4770k Processor
MSI G87-G45 motherboard
Nvidia GTX 780 Graphics card
AX860 Corsair 860Watt PSU
Seagate 3TB Barracuda HDD
Sandisk 128GB SSD
16GB Vengeance Pro Black 1866MHz CL9 Memory
Windows 7

Can you download CPU-Z. Then check the Mainboard Tab in CPU-Z and check the what revision your Southbridge is.
I may be wrong but the USB disconnect after sleep was an inherent bug of the Intel C1 chipset which was corrected in C2. The initial boards all had C1.
It may be that yours is just faulty to the point that it started loosing the USB connection even though its not coming out of sleepmode.
Do check and let us know.

Sorry I missed this part in the initial read.
If that is the case, then it is also possible that you may have a defective PSU. The only way to confirm that is to run with another PSU for an extended period to ascertain if that is a consistent occurrence. If it doesn't happen, well then you know for sure it is PSU related. Also recheck all your connections from the PSU (especially the 24 pin connector)
Are your USB connections on the front panel or are you using the onboard USB connectors on the back?

Dual-Boot; Restart and boot other o/s USB devices not working

I have issue with my msi z97-g43 mobo and Windows dual o/s PC.
Booting with win-8.1, USB devices working very well.Restaring windows 8.1 have NOT any issue.
After shutdown & start PC, choosing to boot windows 7 on bootmanager, USB devices not working in Win-7.
System no hang or occur any error/BSOD message.All startup programs run as normal.
I tried to re-plug usb devices but notting happens... Still not working
But after the win-8.1 shutdown, if i switch off PSU power button, watting ~1 munute for discharge.
After power up PC and boot with windows 7 all usb devices works normaly.
I checked all internal connections. 2 times disassembly all hardware and re-built system, nothing changed.All windows updates and latest drivers installed.
I'm sure other H/W is OK, but I thnik this mobo have a fault.

All hdd's have MBR based partition table.Windows 7 & 8.1 installed in non-efi mode.In BIOS Boot sequence is setting up to non-efi Boot(system) drive as primary.
Before I suspect maybe have a short circuit to pcb or similar thing cause this issue.I take out all parts outside the chassis, and ran this system on the antistatic bag and box.Nothing has been changed.
I have Cooler Master Devastator(MB24 + MS2k) USB keyb+mouse set and tplink wn722n usb wireless dongle.
I have one more pc,based on AMD 970+SB950 chipset mainboard and AMD CPU.I exchange all parts to this amd mainbaord and tested for faulted hardware.All intel system H/W's is ok.All works great
Dual boot works perfectly.Not needs to switch off psu/power back and run system again.
I think msi z97-g43 mainbıoard have a problem.

Some USB devices don't work with MacBook (Unibody)

Hi everybody,
I've just bought a new MacBook and I'm experiencing a few problems with some USB devices like USB memory sticks and USB hard disks.
Whenever I plug in one of these devices I undergo one of the following:
- Copy operations get stuck
- Time Machine backups get stuck
- Finder freezes or crashes
- Disk Utility freezes or crashes
Can someone report the same behavior?
Thanks for any hint
PS: this is what Console reports
+11/24/08 22:50:01 kernel USBF: 22875.305 AppleUSBEHCI[0x6d6e800]::Found a transaction past the completion deadline on bus 0x26, timing out! (Addr: 2, EP: 1)+

Hello together,
i also have seen some USB problems with the new MacBook and just checked a bit deeper.
I have no problems with my USB sticks, the USB hard drive, the MIDI interface - most stuff works. But there still is some special stuff i use for my embedded projects.
One is the USBprog, a universal AVR-based USB device with open source firmware, where i used a programmer emulation. I patched the firmware a bit, as it had problems with the OSX USB stack (was something with OSX sending a NACK and the device doing nothing on this - which is perfectly legal according to the specs). After this patch, the programmer works fine with my Mac Pro (Early 2008). But if i connect it to the MacBook, i get error messages in system.log about this device.
The funny thing - if i connect it via an USB hub to the MacBook, it seems to work fine.
The other device is an Olimex AT91SAM7 development board, which also works fine on the Mac Pro as a CDC device (/dev/cu.usbmodem*), but doesn't on the MacBook. Can be seen with cu - the first connection works fine, the second connection hangs the MacBook, you can log off, but it is impossible to shut it down cleanly. This problem can't even be removed by using a hub. On the Mac Pro, i can use several separate cu sessions on this device without any problems.
Comparing the hardware reveals that the Mac Pro uses an Intel USB chipset and the MacBook used an nVidia chipset. So there is a difference, and this difference might also reflect in which driver is used by the OS for the USB subsystem. The Mac Pro uses OHCI/EHCI, the MacBook used UHCI/EHCI. So the Hardware differs definitely, USB might really get through different software parts.
Besides this, the USBprog problem is a violation of the specs by Apple, so the USB stack in general needs some improvement. The nVidia USB drivers also might need further improvement due to the added problems of the MacBook.
I know, this doesn't help too much, but at least it could be a hint on what goes wrong. I hope, Apple will fix this with one of the next Leopard updates.
