Hi! I'm not very good at english so I hope you forgive me my grammar and punctuation.

The problem is:

MoBo starts automatically after  shutdown. There's no matter how it was shutdown, via OS or button. It looks like you push the power button, OS exits and power is off, two or three secs and it runs again. After, if press the button during post, it will shutdown, finally. If allow it to boot OS, the cycle repeats.

It all began after i decide to move from 066 to 064 bios version. I always use flash drive to update, but that time I deal it with .EB.EXE package. There were no errors during bios blocks update, all ok.

May be the fault was that I start configure bios right after first restart without booting to OS and facing "successfully updated your bios" splash window. After I finished setting system restart twice in a row and only after that I can get to boot screen.

What i tried:

Reset bios via jumper

Reset bios via battery removal

Update back to 066

Update like first time but proper

Doing so brings me no results.

The one thing I can suggest is that reboot script from bios update kit some way now runs infinite on my machine. This is isn't affects stability or so but quite annoying.

I'm not familiar with ITK, but hope it can be fixed without hardware reprogram of SPI.

Thanks in future advance.

A similar question has been asked about the DH77DF and DH67GD motherboards and CIR, but without an answer to either.

Waking a DH77DF board with CIR

Problem with power on using remote and CIR IR receiver

I have enabled CIR in the BIOS and while I can control all functions via my harmony remote (Windows Media Centre mappings) once the machine has booted. I cannot get it to boot from S5 using either the power toggle or the power on button/mappings.

I am using a Interset IR receiver, which is listed as working (on the IR manufactures page) with a DH77DF motherboard.

Intel CIR Receiver. Specialty Computer Products

I am running OpenElec 3.0.3 which includes the nuvoton cir driver, although I am assuming, given that it is loaded post boot, that the the wake from S5 functionality should work regardless of the nuvoton driver.

[    3.297331] nuvoton_cir: driver has been successfully loaded

Can I check:

- that waking from S5 is a working feature of this motherboard.

- that there are no specific options that need to be enabled or disabled in the BIOS, other than enabling the CIR option (which I have done).

Hello,

I'm having problems, whenever I have a GPT drive connected to any port. The BIOS seems to try to boot up the EFI partition (which right now should be a clean FAT32 partition) before loading Setup, if I press F2 (or even if I toggle the Back 2 BIOS button), but after showing all the standard POST information (VGA BIOS, POST Splash Screen - with the hotkeys BEING shown, RAID BIOS), also overriding any options I may have set for boot order, and giving me a pretty ugly "A bootable device has not been detected" prompt.

The only way I've managed to get to Setup or to a Boot Menu was by unplugging the GPT drive from the board, which renders me uncapable of doing any actual maintenance on the actual boot loader problem, even if I could boot Ubuntu from a LiveCD/USB or Windows Recovery Environment.

I had been running this system without a problem ever since I had assembled it, around one year ago. I have my drive setup as follows:

256GB SSD on Port 0

1TB SATA2 on Port 1

1TB SATA2 on Port 2 (in RAID 0 with the previous one)

1.5TB SATA3 on Port 3

DVD-RAM on Port 4

nothing on Port 5

After a long time running fine on only Windows in UEFI, I decided to install Ubuntu with it on the SSD. After many unsuccessful attempts to boot back to Windows (I was able to boot up Ubuntu), I tried to mess with the EFI files manually, as it seemed like GRUB had changed some of Windows' files there. All I did was append ".grb" to GRUB's "bootx64.efi" and rename "bkpbootx64.efi" under /EFI/Boot and /EFI/Microsoft, in order to see if I could restore Windows' original bootloader, in place of GRUB, and if this way it could boot back up, and then I couldn't even get to the BIOS setup before Windows Boot Loader shows up (and this still has the same problem as before). At this moment, if I tried "Startup Recovery", it showed up a "Windows is loading files..." progress bar, and then went back to the same boot loader screen. If I tried "Startup Windows Normally", it showed "Starting Windows" for a brief moment, then showed the same "Windows is loading files..." progress and finally, left me back at whatever screen I was BEFORE the Windows Boot Loader - if I came from GRUB, it would take me to GRUB again - I could repeat the process indefinitely without rebooting; strangely, if I came straight from the One-Time Boot Menu, it would also take me back to it, but this time without any Optical Drives listed.

After only getting success on reaching BIOS Setup by unplugging the SSD itself, I've took it out, reformatted the EFI partition, and now all I get is the doomed "A bootable device has not been detected", even if I have a bootable USB device, or a bootable CD - which are both set to boot before the Hard Drives.

The SSD is the only GPT drive, all the other ones I've maintained as MBR drives.

The system specs are:

Intel DX79TO Mainboard

Intel Core i7 3930K

Markvision 4GB DDR3-1600 in Quad Channel (16GB total)

NVIDIA GeForce GTX295 (on first PCI-E slot)

Corsair 750W PSU

Has anyone got any idea on what I could try?

Thanks in advance...

Hello everybody,

I have just assembled a new computer and used DX79SI and a 3930K processor, with 32GB Patriot 1333 memory and a GTX680 video card. All seemed fine until I have tried to install Windows 7. The installation loads the first screen until the end of the bar and when it goes to the next screen it shows the image and 1 second after it the system restarts. It has happened with any OS I have tried from XP to Win7, Vista, even SuSE or Ubuntu, it starts the installation and suddenly rests. I am using a Corsair H100 cooler, a Seventeam ST-550P-AG power supply and a Crucial SSD too. Have tried with an old video card 9600 and it acts the same way. Have looked for something in the Internet but nothing really like what is happening here with my new system. I have discovered that the HOT CPU led blinks red at the moment the system restarts but checking the processor temperature right after the rebook it shows the same 49 celsius that is it showing when the system is on setup fan monitoring screen. What is strange is that the fan RPM is almos all the time in 2133 RPM no matter how much noise you can hear from the cooling system, loud or low.

Someone has an idea of what could be going on? I have tried removing memory sticks and tried with 1, 2 and 4 and same happens. Power supply too weak? I can let the system on setup screen and it stays there working fine.

Thanks,

Sergio

Hi,

I've just purchased a DH87MC motherboard and I have the following issues:

1. When I enable XMP, in BIOS I can see the ratio going to 12 and result going to 1600MHz but the final result in windows is 1333MHz. Only when I manually select 1600 then it works fine.

2. Usable memory is 7.8GB, even though I've disabled onboard graphics.[Windows7 x64 Professional]

3. The system memory buss is at 99.77 instead of 100MHz, resulting in lower frequencies for my CPU [i7 4770]

• I've tried playing around with the EIST and other turbo features, no success
• Initially in the system I had the bus to 100MHz but the multiplier was fixed at 30, so the resulting frequency was 3GHz, not the default 3.4GHz

I have the latest BIOS installed [0047]

Any suggestion is kindly appreciated.

Thank you.

Hi all,

everytimes I want to shutdown my PC with Windows 8 Pro with Media Center x64, then it will be a restart. If the system is running the Standby Power LED is blinking. At the Post LED I can read a Ab or A6 and at the second a 30. I hope anybody know what I have to do to troubleshot These problem.

Here is my system components:

DZ87KLT-75K into a Silverstone SST-RV01 B-W USB3.0 Raven Case

i7-4770K (nothing is overclocked with boxed Cooler)

Patriot Viper3 2x4GB Intel Extreme Masters Edition 2133MHz (in automatic mode @1600MHz)

Silverstone SST-ST1000-G Strider Gold Evolution PSU (the manufacturer write on his website that is Haswell compatible)

EVGA Nvidia Geforce GTX 780 SC connected to the 1st PCIe x16 (HDMI-Connection to a BenQ RL2450HT)

OCZ Vertex 4 256GB connected to SATA0
2x2TB Western Digital Caviar Green (configured as a Win8 storageplace with mirroring) connected to SATA2+3

Samsung SSD 64GB connected to SATA4

LG BH16NS40 BDRW connected to SATA1

US-Robotics USR5638 PCIe Faxmodem connected to the 1st PCIe x1

Hi,

i bought a DQ77MK and an i5-3570T but get into trouble while booting. Boot screens will show up and after a few seconds the board switch off and on again. After talking to Intel support i got the information the i5-3570T is not supported by this board, bad luck. I bought a G2020 instead and a Gigabyte board which does support the i6-3570T. Same problem with both combinations, so i switched RAM and power supply. I checked Debian Linux, which is my favourite system i would like to install, sysrescd and Windows 7. Windows 7 run a little bit longer but after 60sec there is the same result, boards does switch off and on again.

I tried a lot of things and now i get the DQ77MK working with using a dedicated graphic card. What could be the problem with the integrated graphic? I know there were problems with older kernel versions but the sysrescd use 3.8 which should support Ivy bridge.

Any ideas how i could get it running with internal graphic?

Cheers, Claus

I have installed Windows 8.1 Preview on an Intel-DG33FB-based PC. The O.S. installed beautifully, but there is a yellow exclamation in Device Manager, under Unknown Devices, next to a "PCI simple communication device." This obviously refers to the Intel Management Engine Interface, which is no longer listed anywhere in Device Manager. The I.M.E.I. has no Windows 8.1 driver and none can be installed. I contacted Intel customer support. After several days of silence and not before a message to their C.E.O. I received the following reply from "Andre B." of Intel customer support:

Please take note of the fact that the board DG33FB is out of interactive support (EOIS) as stated in the notice on following webpage: http://www.intel.com/p/en_US/support/highlights/dsktpboards/dg33fb Intel will therefore no long provide support for the DG33FB board, and no new drivers will be developed for this board. [...] Windows 8.1 preview is not a production version of Windows. Drivers are provided for production versions of validated operating systems, I regret to inform you that Intel does not provide support nor drivers for non production versions of operating systems.

I would not install Windows 8.1 Preview or any other version of Windows 8.1 on any computer system that has any Intel hardware in it until such time as Intel has released all its drivers for this operating system.

My understanding is that any host USB 2.0 connection should be able to supply up to 500mA of power to a USB device. However, is it possible draw too much current from the controller? For instance, if the controller is connected to the maximum number of devices (in this case 14) and each is drawing 500mA, could this affect the performance of the controller? I couldn't find any total maximum spec on this board. I was looking at the spec for the ICH10 chipset. It offers I think 12 USB (I think some USB 3.0 and some USB 2.0, which might have different current specs) ports. As a thought experiment, let's say that they need to have 500mA for each port. This would mean that the controller would need to draw 6As at 5Vs somewhere in it's maximum specs. However, I don't see anything close to that in the spec (granted it would be easy to miss as the specs are hundreds of pages long). And at lower voltages, I'd expect to find an even higher current draw which I couldn't find either.

Any help would be appreciated! Thanks!

Hi Gurus,

We had integrated a system with Intel DX79SI, Intel 3960X, 4x8GB RAM, Asus HD7970 DC2T-3GD5 GPU, Adaptec 6405 RAID Controller, 4 SAS Drives, DVD RW, 1000W Cooler Master PSU etc. On Powering up the system, the POST screen along with system details RAID config etc and freezes with 0_ post error on screen. The On board Diagnostic LED show 00. But system does not boot to OS. The display shows 0_ on right bottom. The same graphic card and other components are functional with Asus Rampage iv extreme. The BIOS ver is 553.

Kindly advice and help to find a solution.

Thanks in advance.

Hi.

I've tried countless option in the BIOS, and no particular option allowed me to activate MSI-X (http://en.wikipedia.org/wiki/Message_Signaled_Interrupts).

It seem to be a motherboard related problem, as all the hardware move into an other computer manage to activate MSI-X.

Without MSI-X I'm getting way too much interrupts, which make my CPU die under interrupts. My NIC is bombarding the CPU of interrupts.

I've done more than 3days of testing different kind of setup, be it under BIOS settings or OS setting. This motherboard just don't allow MSI-X at all.

I've resorted to an old motherboard (6-7years old), which is doing better than this DH77DF just because of the MSI-X.

I'm expecting it to be fixed by Intel or told that this motherboard can't do something that is a standard since more than 8years.

I need a clear answer about this motherboard been able to do it's job, or not.

Thanks.

Dear,

I bought DH87MC and 4th gen i7 4770 five days ago. Issue is whenever I try to copy data on external drive using any of USB 3.0 port, drive automatically disconnects and reconnect while the message appears that destination could not be found. However, same drive is working fine on USB 2.0 and on my HP Probook USB 3.0.

After Net search it was found that problem is with the Intel chipset with C Stepping 1.

Can anyone help me out over this issue.

Regards,

Nauman

Hi,

I recently build a Windows 8 Pro x64 PC Based on the Intel Desktop Board DX79TO, but even after installing the available fix for the 2 USB 3.0 ports at the rear of the PC i keep getting the same problems as before.

The ports work like they should, except that I keep getting the same problem at start-up everytime there is a device still attached to the port.

• "System hangs on POST code 58 for one minute if any device is attached to USB 3.0 ports, and then continues the boot process."

Even though start-up from USB is placed UNDER those of the internal HDD's in the boot sequence.

Does anyone know how to fix this, or is someone familiar with the problem at all?

Would be nice if I shouldn't have to disconnect my 3TB Mybook 3.0 everytime I want to boot my pc...

Many Thanks

Sven

Hi all,

I plan to use the Intel D2500HN motherboard in order to run some old control software that uses the parallel port interface, under winXP. The problem is that the software only works when the LPT1 address is mapped in the typical LPT1 address: 0x378. Could you please confirm me whether this motherboard will fit my needs?

Regards

hi:

i cant upgrade the bios

my board version is 0076

i have windows 7 x64. when i try the Express BIOS Update. version 0105 & 0110 The PC restart normally without flashing and the express installer says the bios updated successfully. but when i go to the bios its still the same version 0076.

when i tried Express Bios Update version 0119. The pc restarted without flashing and the express intaller says the bios did not successfully update.

when i tried iflash bios update :

by typing iflash2 /s it shows that the last update was successful\

by typing iflash2 /p bl0119p.bio

the pc restarts and no flashing is done. still same version 0076.

by typing iflash2 /i

any help ????

Hi

We have dh87mc mainboard in the bios it does not list any cards populated in any of the slots, so we cannot install drivers for these devices.

Graphics cards will work in the pcie slot but does not show in the bios. We cannot get working network card, tv tuner card & usb 3.0 card

Thanks Craig

Ok I have this problem for the last 2 years since I upgraded the bios for my P55WB.

My PC boot by itself for no reason!

I thought like some people told me that it's the PSU but I changed it last week with a brand new XFX,so it's not the PSU.

Some people told me that perhaps the PC's case power button is broken or something,I replaced the case as well with a new Thermaltake.

Another option was to disable wake on LAN but right now I don't have any network cable plugged nor wake on Lan ON.

So it's obviously the motherboard!

I upgraded to the latest bios but still no joy.

I even changed my graphic card but the problem was still here.

So how can I fix this damn problem??boot start

My new DZ87KLT-75K has difficulty turning on. When my machine is off the red "Power Supervisor LED" is lit constantly. When I turn on my machine, I get prompted with a message telling me that the Intel Power Supervisor has detected a "Catastrophic Power Event." If I press a key at this message, the Power Supervisor LED turns off and the machine usually proceeds to POST and boot to Windows 7. Sometimes instead of booting I instead get the red Power Supervisor LED combined with the memory error beep code (three beeps, repeat). When this happens the machine turns itself off automatically. Once booted to Windows the machine seems stable with good thermals and game performance. The power supervisor LED stays off when Windows is running.

My first thought was the power supply. I have tried two Corsair AX860i PSUs so far. I RMAed the first one because I figured if the power supervisor LED is lit then it must be a problem with the PSU.  Today I got another of the same exact model, but the above symptoms persist. Corsair's website insists that this model is compatible with Haswell.

A separate but possibly related problem is that I seem unable to update the BIOS on the motherboard. I tried twice. Both times the machine shut itself off and went into BIOS recovery mode. I suspect this power problem is to blame.

Here are my full specs:

Core i7-4770K

DZ87KLT-75K

32 GB (8GB per DIMM) of Dual Channel Corsair "CMY32GX3M4A2133C11"

Nvidia Geforce GTX 780

Samsung 256GB SSD

Western Digital 2TB HDD

Corsair AX860i PSU 860 Watts

Do you think it is safe to use this machine until I get a fix for this? Could using it damage the components?

Any help would be greatly appreciated!

Hi,

I have a D2500cc board which has a very strange beavior: In the bios settings I have choosen the option After Power failure  - Always on. This is needed because I have no Power on Switch only a power button on the Power supply. When I perform a soft shut-down I will have to wait about 3-5 minutes before I am able to restart the board by giving power on the power supply. If I do a hard shot down by cutting of power then I am able to restart the board within a few seconds. A reboot out of windows does also make no problems. Does anyone have a solution for this?

I recently built a new system with the DH87RL and an i7-4770K. Everything works just fine except I am not getting any audio from optical or HDMI. If I make them the default device in the Sound control panel, I can see the volume meter go up and down but no actual sound comes out of my speakers. Video through HDMI works fineI checked the receiver audio input settings to make sure they were set properly, but still no sound. I installed the drivers from the disk provided. Defective board? Other issue?
