Gigabyte P67/Z68 boot cycling problem - Page 61

post #601 of 811
Well, here it is almost six days since I wrote to Gigabyte:

This is a new machine. The parts were purchased yesterday, 01/01/2012. Windows is not yet loaded.

The machine starts and lets me in to the BIOS setup. I can stay there for an hour or longer with no problems and the CPU will report a low temperature. If I try to load Ubuntu Linux the load fails at the same place every time with the error: "panicing machine check CPU died". I tried booting Knoppix Linux and received a similar error. I have also seen a "Machine Synch" error.

I have tried running with two sticks of memory in different sockets and with one stick of memory. I have moved the DVD to different SATA ports. I turned off the feature "USB Storage Detect" as recommended by several forums. The problem still persists.

Apparently the "Boot Loop" problem is well known with Sandy Bridge and Gigabyte boards seems to have a reputation for being especially troublesome in that regard.

The problem does not seem to be related to the memory or to overheating. Any assistance you can offer will be greatly appreciated.

Under "Additional Comments" I included this note:

Memory is 4 x 4 gig Micron "Ballistix Sport", part number BL51264BA160A.16FH, which Micron guarantees is compatible with this motherboard.

The CPU is cooled with a Thermaltake Contac 30 cooler.

The system has only a USB keyboard, a USB mouse, and a DVD drive. There is no hard drive yet.


Here is their advice:

Dear Customer,

If you monitor cpu temperature how high does it reaches?
Make sure it does not exceed 65c at anytime.
Do attempt to reduce memory down to single module and disconnect any cards installed onto the board for additional testing and try reloading the OS again.

They did not read my note very well.

1. If you monitor cpu temperature how high does it reaches?

[INDENT...]and the CPU will report a low temperature.
...The problem does not seem to be related to the memory or to overheating. [/INDENT]

2. Make sure it does not exceed 65c at anytime.
True, I did not give them a number. I wrote back and told them it was no higher than 25c.

3. Do attempt to reduce memory down to single module and disconnect any cards installed onto the board for additional testing...
...I have tried running with two sticks of memory in different sockets and with one stick of memory.

In my additional comment I had said: "The system has only a USB keyboard, a USB mouse, and a DVD drive. There is no hard drive yet." And they want me to remove things for additional testing?

4. ... and try reloading the OS again
...If I try to load Ubuntu Linux the load fails at the same place...
...I tried booting Knoppix Linux and received a similar error.
...I have no hard drive, only a DVD drive. I can't load an OS.

My reply to them, 01/09/12.

The CPU temperature was running 20-25 degrees celsius.

The first time I started the system it had only the motherboard, CPU, and DVD drive. There was nothing else, not even a hard drive.

In my note I said that Windows was not loaded. There was no hard drive so I could not load it. I did try loading two versions of Linux from CD and they failed.

What about the "boot loop" problem so many people have mentioned? I updated the BIOS from F9 to F10 with no change. Many other people have tried BIOS updates.

Let's see how long the next answer takes.

they obviously aren't doing anything to fix the problem and they've left us all hanging out to dry. if they cared - it would be stickied at the top of their forums, and they'd be providing daily/weekly updates.

i'm so beyond annoyed with the customer support by that company.


short of a class action suit, is there anything else we can do to try and get them to uphold a level of customer service that'll actually get this problem resolved?

Got it stable again!
BIOS F6 loaded optimismed safe and only changed: vcore, DRAM Voltage, Memory timing, Clock ratio, PWM freq, and Over current protection.

Stable on 4500Mhz and 4723Mhz

stable as in no boot cycles, or stable as in no lockups?

No boot cycles, not cold boot cycles, no BSOD. 3 days and counting

For a gamer or computer enthusiast that might be acceptable.

For someone who relies on the system every day to make a living, and who plans to run the system for the next 4-6 years, a potentially unstable MoBo would be totally unacceptable. If it were to die in two months it could be weeks or months until the system was back on line.

I went to Gigabyte because Asus support was slow. Gigabyte support seems to be non-existant. With a major problem in their entire Sandy Bridge product line one would think they would be all over themselves trying to make things right. Apparently not.

Ive got same problem ga-z68x-ud3. I have NEVER OC. Last night some updates installed, then i noticed everytime i told it to shutdown it would then start up again. Ok finally it shut off. Today woke up to Voltage error message, so i restarting now im stuck in this damn loop. Everytime, ive tried clearing cmos, power supply everything i cannot get out of it. It starts up posts to memory info maybe 2-5 seconds then shuts off and restarts. Has anyone NOT been able to get out of this?

Bit of a small update -

As for the splash screen advise turning that off and DON'T be tempted to enable Quick Boot!

My first UD3 had the reboot loop problem,then I RMAd it and got a brand new replacement, that too got the reboot loop, I RMAd the replacement, then i received my SECOND brand new replacement , but i sold it right away. And guess waht nobdy wanted it because they knew. In the end i ended selling it for cheap. Bought Asrock Extreme 4, Best board I ever had period.

This occurred 2 - 3 months before this thread was made.

They should have recalled these
