Freeman0729, I would like to inform you that this motherboard has been out of support since June, 2013.
The behavior you are experiencing could be related to the speed of the memory since it is 1333MHz.
The i7-940 processor does not support XMP, so it cannot be over clocked since it is being limited by the memory controller hub. The only CPUs that can be over clocked are the extreme or unlocked processors such as the i7-965, I7-975, i7-980x and the i7-990x.
You may want to try using 2 blue slots in order to check if the processor is able to handle dual channel.
Also try to test all memory sticks on a functioning DIMM just to make sure all RAM works OK.
I would recommend you to check the system using DDR3-800/1066 memory type. The following link will show you the memory specifications for your processor http://ark.intel.com/products/37148/Intel-Core-i7-940-Processor-8M-Cache-2_93-GHz-4_80-GTs-Intel-QPI?q=940.
Thank you for the reply but I'm not sure you understood the question.
I understand the board is no longer supported thus posting my question on the forum section for help and not calling Intel. The problem I am having does not relate to "overclocking". My post stated that I was having issues with using the boards settings at its most basic. The RAM configuration doesn't work on the blue slots with multiple modules. As stated, these are the only configurations my board will stat up in:
Black channel A DIMM 1 & Blue slot Channel A DIMM 0 = STARTS JUST FINE
Just Blue slot channel A DIMM 0 = STARTS JUST FINE
Triple channel ram does not work. Double channel does not work.
The memory you are using is not under specifications, therefore you may get any on these two scenarios:
1st. The processor by default down clocks the memory speed to 800/1066 MHz and the voltage to 1.5v. This configuration will be good for the processor but we don't know if your memory responds properly to it and eventually it will give you performance and stability issues.
2nd. The SPD (Serial Presence Detect) chip of the memory forces the MCH (memory controller hub) of the processor to match the native memory settings. If this happens, the processor will be forced to amplify the voltage needed by the memory and to sync the speed requested by the memory as well. In this case, this customization will end up with processor damage and Intel won't provide warranty to any processor failure caused by customizations. Even if the voltage of the memory is 1.5 volts but the bus clock is still high the MHC is forced to cycle at a clock speed it is not designed for.
If configuring the memory manually to match the native memory settings or selecting an XMP profile, the processor is immediately over clocked and it is expected to have problems.
As I recalled on thread https://communities.intel.com/thread/30806, the memory is double-sided based on x16 and this type of organization is not supported by the motherboard. http://www.valueram.com/datasheets/kvr1333d3n9_2g.pdf
You can verify that information on the TPS of the board on pag 15.http://downloadmirror.intel.com/18128/eng/DX58SO_TechProdSpec.pdf
Finally if you think the issue is related to the motherboard, you may contact our Warranty Department so they can help you to replace the unit if it is still under warranty : http://www.intel.com/p/en_US/support/contactsupport
Just picked up some 800/1066 MHz ram and triple channel or filling a 4 slots still does not work.
It's the board.
As a last attempt before you condemn the board, you should remove the CMOS battery (and replace the battery if it's old) for a day then do a Recovery BIOS update with the latest BIOS version. Also, check the product manual to ensure that any jumpers are properly configured. Make sure your BIOS is in a default setting mode for resolving the memory issue.
Also, check the capacitors on the board. Electrolytic capacitors degrade with age and heat. The best way to check the caps in circuit is with an ESR meter. Some defective caps may have visible indications of leaking and swelling and some may not. That's why the most effective test is the ESR meter. Recapping a motherboard is not unusual.
Do a Google search for more information on what I mentioned.
Freeman0729, would you might to provide me the model number for this memory?
