DZ68BC Bios Stability Issues Fixed


Ever since I updated my bios from 0028 to anything newer the board has been unusable.

Random reboots, no video, no post, no stability, no ME Management ver. displayed in bios. Just plain garbage.

The board worked flawless before the update, and Intel won't let anyone go back to 0028.

I read in another post about the memory slots being changed in the bios beginning with bios 0035.

Sure enough it looks like the black slots are the primary slots. Both black slots are slot 0 and both the blue slots are slot1.

The bios from version 0035 and higher REQUIRE a memory module in slot 0, the first black one closest to the CPU.

This cured everything about the board!!! Even the overclocking problems with bios 0035.

I am currently running bios 0042 with absolutely no problems.

Here is my current setup:


Corsair Vengeance 1600 mhz. Two 8 gig sticks. Both in black slots.

Intel ME ver. shows in bios

Windows 7 Pro

All latest video and chipset drivers from Intel's web site.

DZ68BC DVI video port

Mildly overclocked to 4.2 Ghz

Hope this helps.

I recommend clearing the CMOS. Clearing the CMOS memory can solve BIOS corruption, but causes you to lose all customized settings in the BIOS. You also need to reset date and time in the BIOS setup after clearing the CMOS.

Follow these steps to clear the CMOS:

  1. Turn off all peripheral devices connected to the computer. Disconnect the computer power cord from the AC power source.
  2. Remove the computer cover.
  3. Turn off the computer and disconnect AC power.
  4. Remove the battery located in the motherboard for at least half an hour.
  5. Remove the RAM, the video card if you have, hard drive and any other component install on the motherboard, all that for at least half an hour.
  6. Then place everything back on the PC including the battery and do a BIOS update.

You can do a BIOS update to the latest BIOS version 0042 by following these instructions:
