I'm building a new system:
- Intel DP55KG LGA1156 Motherboard
- Intel Core i7 875 2.93GHz LGA1156 Processor
- Corsair Vengeance 2 X 4GB DDR3 1600MHz (8GB Memory Kit)
- Thermaltake Frio CPU Heatsink and Fans
- Corsair GS600 Power Supply
- EVGA PCIe 16X e-GeForce 8600 GT (nvidia) Video Card
- Microsoft Windows 7 Professional 64-bit 1-Pack for System Builders - OEM
To start, I assembled the system without Keyboard or mouse and one stick of memory in each of the blue slots and none in the black slots.
Turned the system on and got the three beep error code for a memory error.
So I pulled the memory from Channel B Socket 0 and left Channel A Socket 0 and tried to boot.
The system ran through the boot process and stopped on a BIOS Code 06 and no display on my monitor.
Of course I couldn't find code 06 and I figured I needed to unplug one of the monitors for initial startup.
NOTE 1: Upon trying to boot again, the system would power up for about a half second then power down and repeat every few seconds until I hit the hard off button on the PSU.
No POST codes displayed on the MB and I tried power down and boot again and again.
I even tried the CMOS reset by pulling the battery and reinstalling.
Frustrated, I pulled everything out of the case and reinstalled the CPU and Heatsink on an anti-static bag on my dinner table.
- No video, mouse, or keyboard.
Set up bare minimal components on the table top and everything seemed to do okay.
Adding one component at a time and booting successfully until I tried to add my DVD drive.
Again the system went into an endless cycle of power up then down but this time with POST codes displayed.
So I disconnected everything and started again.
Everything seemed to go okay so I put everything back in the case - huge mistake.
It wouldn't POST again.
Now I think what had happened is that the system found an issue and because I didn't have my monitor or KB connected, I wasn't able to see nor respond to any information of the screen which caused an error the next boot attempt.
Disassembled everything again on the table with full video, mouse, and keyboard support and was able to install Windows 7 Pro 64bit without any trouble.
I can only put memory in Channel A!
I tried one stick in each blue socket (Channel A Socket 0 and Channel B Socket 0) but the system will not POST (See NOTE 1 above).
I tried each stick of memory individually and both were fine.
Finally, I tried one stick in Channel A Socket 0 and Channel A Socket 1 and it worked.
The system will run with the memory configured in Channel A Socket 0 and Channel A Socket 1 however, this doesn't provide dual-channel functionality.
Am I missing something????
I've updated the BIOS to the most recent version without problem but it doesn't fix the problem.
Do I Have A Bad Motherboard???
A few notes for others:
- Your network adapter will not function until you install the software on the provided CD.
- Large heat sinks may not allow the use of one or more memory slots and when the video card is installed you cannot access the CMOS battery and have a poor view of the POST Code LED Display.
- Additionally, large heatsinks make accessing the 8 pin CPU power plug difficult as well as CPU cooling fan header.
