Random Reboots on DX79SI

webadmin@intel.com — Sun, 19 May 2013 20:32:38 GMT

Title says it all. Specs are below. I bought this board less than 30 days ago and now that I have eliminated everything I possibly can, it seems like there is something wrong with the board. Scope of the problem .... PC boots fine and runs anywhere from 10 minutes to 10 or more hours ... then just decides to reboot itself. No BSOD, no errors in the event viewer, no errors in the BIOS. I've replaced the RAM, GPU's, power supplies. The only thing I have not changed out is the CPU, but at this point, I do not suspect it being the issue. There are NO heating problems or power issues. System is plugged into an APC UPS.

Intel DX79SI

Intel i7-3820 CPU

Thermaltake SP-850-M 850W PSU

PNY DDR3 1333 16G Memory

2x Gigabyte GV-R797TO-3GD 7970 GPU's (And yes, I am having the "Boot to Code 0" problem as well, but at least the cards initialize after windows loads. I used an old Nvidia GPU to get everything installed and working. Would be nice if Intel would fix this persistant issue.)

Corsair H55 CPU Water Cooler

Samsung HD502HI 500GB SATA Drive

Windows 7 Pro x64

Specific to the board, I've flashed to the latest BIOS and still have the same issue. I tried running Windows 8 Pro x64, issue still exists. I have replaced everything except the CPU and the problem still exists. No overclocking has been done, everything is stock until I was able to resolve this issue.

Any ideas?

GMA 3600 series 7x64 drivers....

webadmin@intel.com — Tue, 07 May 2013 19:35:01 GMT

Today I found out that I have a motherboard that is 64bit capable, but lacks 64bit GPU drivers.

The motherboard is a DN2800MT. After installing 7x64 I was surprised not seeing unidentified hardware (that's a first for me with Windows), however, I noticed straight away that Windows was using the build-in GPU drivers. Those are so basic that even Patience starts complaining about the lack of graphics performance.

Not long after that I found out that Intel refuses to make 64 bit GPU drivers for this motherboard, while there are 64bit chipset, LAN and sound-drivers available. So why make those and not GPU drivers?

Then I found someone on this forum who linked to a beta driver (GFX_Vista_Win7_64_8.15.8.1050_Beta5.exe) that supposedly supports this particular GPU. Well.... after running the driverinstaller and a reboot, I got a BSOD. Another reboot -> BSOD. Safe-mode -> delete GPU driver -> no more BSOD, but crappy graphics performance due to the standard Windows driver being used again.

After a second attempt, not using the driverinstaller but let the device manager install the driver, it seems to run without problems, didn't get BSOD's anymore. Now I haven't tested much, Windows starts, graphics performance increased and Patience is no longer nagging about crappy graphics, gonna try more tomorrow.

Why are you (Intel) still refusing to make a GPU driver for this motherboard for any OS besides 7x86? This motherboard can run 7x64 without problems. The only thing that's a problem is the lack of GPU drivers. And no, I am not gonna switch to 7x86 because the full amount of RAM is not usable in 32 bits OS's.

DX79TO And PCIE 3.0

webadmin@intel.com — Fri, 05 Apr 2013 13:00:20 GMT

Hello All,

I am using a DX79TO with an i7 3930k.

I want to purchase a Radeon HD7870XT and that card uses PCIE 3.0.

The box of my DX79TO has an * by the PCIE 3.0 saying it would work with processor that supports PCIE 3.0.

So would the i73930k enable PCIE 3.0 support on this board.

Thanks

DX79SI - high voltages when overclocking :(

webadmin@intel.com — Wed, 06 Feb 2013 21:35:14 GMT

Hi everyone,

I have an Intel DX79SI and a 3930k CPU on it.

I use the Intel Extrem Tuning Utility and CPU-Z to monitor my voltages. CPU-Z seems only to monitor the Core VID, not the Core Voltage. The Extreme Utility monitors the Voltage.

My Goal ist ~4.1-4.3GHz on all cores and 4.5GHz turbo on 1 core. In the BIOS I have 2 possibilities: Auto-voltages seem to get too high. About 1.3V peak-voltage on 1 core and a 1.4V core VID. For all cores it gets less because of the V-Droop on maximum.

When I set the core voltage manually to 1.25V it stays there all the time. I had 4.1GHzx6 - 4.5GHzx1 stable which is great for 1.25V in my opinion. But on idle the VID in CPU-Z goes down to 0.8V or soomething but the Extreme Tuning Utility shows more or less table 1.25V all the time :/ (again, 1.19V on all cores stressed, because of V-Droop)
What is healthier for my cpu?

I wanted to keep this system for at least 4 years.. so I don't want to kill my cpu by electron-migration.

What makes me wonder is: Other mainboards can set the Voltage-Offfset negative, I can't. To get it stable at 4.3GHzx6-4.5GHzx1 I need to set the voltage offset to 0.04V. Is there any possibility to set the offset negative? Like "-0.04V"?

And do you have any suggestions how to set the cpu in BIOS for this overclock?

Watchdog for Desktop board DH57JG not working under Ubuntu Linux

webadmin@intel.com — Tue, 21 May 2013 14:53:54 GMT

We are experiencing a problem with the watchdog on DH57JG motherboard that uses the H57 Express chipset. We have found that the watchdog is not resetting the system when we stop writing to the watchdog device.

We have several hundred appliances that use this board all running Ubuntu Linux 10.10, 12.04 or 13.04 (32 and 64 bit) using kernels 2.6.38.8.22, 3.2.0-29 and 3.8.0-19 respectively.

Chipset:

DH57JG Motherboard:

http://www.intel.com/content/www/us/en/motherboards/desktop-motherboards/desktop-board-dh57jg.html

Has anyone had this issue or similar? Does anybody have this board/chipset and can test if the watchdog works under Operating Systems?

We have upgraded to the latest BIOS for this board. BIOS version is JGiBX10J.86A.0663.2011.1019.0408

Thanks David

DQ77MK: wireless mouse does not work in BIOS

webadmin@intel.com — Sat, 18 May 2013 11:09:51 GMT

BIOS 0059

wireless keybord and wireless mouse (MS Natural Wireless Ergonomic Keyboard & Mouse 7000 )

The keyboard works fine, but mouse does not, but both are O.K. in 0058.

I have tried plug in the wireless receiver to all usb ports, nothing helped.

DH61AG Bios

webadmin@intel.com — Wed, 06 Mar 2013 15:18:10 GMT

I have the DH61AG motherboard with bios 0045. I would like to update to version 0104. The instructions at the download page are contradictory. See following cut and paste from the download pages.

Case 1.

If your system's current BIOS version is 0039 through 0045:

1. Update to the transition version 0099.

2. Then update to 0104 or later.

Case 2 from release notes for the bios.

If your system's current BIOS is 0039 through 0045:

1. Update to the transition version 0039

2. Then update to 0104 or later.

Which Method is the right one?

DQ77KB sudden power on failure

webadmin@intel.com — Sun, 19 May 2013 13:47:36 GMT

Hi folks,

Has anybody seen an issue with the DQ77KB mainboard suddenly refusing to power up?

This feels like it's going to be a warranty claim type of thing, but I'm still hoping to find a fix that doesn't involve sending the hardware back.

In a nutshell the mainboard has been running fine for a couple of months, I had just powered the machine down and as it runs headless and had moved it to a new location, plugged it into a monitor, keyboard, etc as I wanted to upgrade the bios. A task I had just on another identical machine (they form 2 nodes in my virtualisation lab).

After plugging in said machine and pressing the power button, all I get is a brief spin on the fans (CPU and chassis) and the blue light towards the rear of the motherboard flashes on for about 1 second. Otherwise, no output. I haven't changed anything about the machines hardware since I built it back in early Feb 2013.

Since this, I've tried swapping all the hardware, SSD, CPU, RAM from the other identical working machine and nothing, the issue definitely seems to be mainboard related.

I've also tried disconnecting the power and CMOS battery and leaving it for an hour just to be absolutely sure, nothing.

On a whim I tried the MBEX reset jumper, didn't actually expect that to do it, but clutching at straws right now

Any tips, ideas, gladly appreciated? Anything obvious I've overlooked?

Kind regards, Keith

DZ68BC 003X BIOS, I Found The Root Problem (Attention Intel Please Respond)

webadmin@intel.com — Fri, 12 Apr 2013 11:42:09 GMT

As the title states I found the root cause of all the misery and agony that DZ68BC users have been encountering with the 003X BIOS.

The root cause is the Intel Management Engine Version.

Initially the DZ68BC was designed to run only one version and that was the Version 7. which works pretty well. Then Introduction of 3rd gen had them Include Version 8 in the BIOS file and by doing so lead to the problems encountered with various versions of the 003x BIOS.

The issues arise coz the BIOS files carry two versions of Intel ME which are 8 & 7, the initial ones did not have both versions in the BIOS files they had only one version hence there were no issues.

I will not go into details of various methods that lead me to this conclusion, unless if any one wants please reply in the thread and i will explain.

DZ68BC Boards that I have tested versions 403 and 402.

The simplest answer and conclusion is Intel should compile 2 separate BIOS files for the DZ68BC

1. For people with 2nd Gen the BIOS should only have the Version 7 Intel ME

2. For people with 3rd Gen the BIOS should only have the Version 8 Intel ME

eg the 0039 BIOS should be two (0039 2nd Gen) and (0039 3rd Gen)

The problem arises when the two are present, and the board cant determine correctly which to install depending on scenario of the set up.

eg If you are to install a 3rd gen you need to have 2nd gen to update then while updating the BIOS the Intel ME stays at the V7 instead of moving to V8 then when you instal 3gen CPU it works but the system becomes unstable mostly with the 0035 BIOS, if you update from 0035 to any 003x or run recovery with same BIOS it moves to V8 the instability is gone but you get Intel ME and PCH issues and if on the 0035 Overclock issue on it.

So its either Intel Complies 2 BIOS for the Board or 1 that has only Version 7 of the Intel ME and they should forget about the Version 8.

Intel PLEASE RESPOND TO THIS acknowledge by also producing a BIOS UPDATE

intel DZ77GA-70K, Windows 8 Pro, Wireless Module (Ralink)

webadmin@intel.com — Fri, 17 May 2013 15:51:52 GMT

Hi Experts,

After struggling a lot I am able to install Windows 8 Pro on my Intel DZ77GA-70K Motherboard on a SSD, Now I have issues with the Wireless Module bundled with the Mother Board. The wireless driver was installed when Win 8 installed. but I am unable to browse any website though I am connected using Wireless. If I connect a Ethernet cable I am able to access Internet but not with Wireless. Sometimes I am able to connect but in next moment I am getting disconnect and if I am connect the speed is damn slow though I have a 10MBps line. I am sure, this is a Wireless Driver issue. I have tried installing the latest driver from Ralink

still no go. Any help on this would be much appreciate.

Thanks and regards,

Suneet
