I would need to get more information in order to find out if you got a defective motherboard, processor or this is a compatibility problem.
So please provide more detailed information on your system in order to help you. For example...
- Which is the model number of the processor you are using?
- What is the part number and manufacturer of the memory sticks you have tested with?
- Please let me have the AA number and Serial number of the motherboard. The following link provides information on where this information should be located on the motherboard: (The serial number is on the left of the AA number) http://www.intel.com/support/motherboards/desktop/sb/CS-009008.htm
Regarding the power supply, I recommend you to keep using the 500W PS.
Processor is an i5-3470, Product Code: BX80637I53470, S/N: 2R252139A0045
Memory is: G.SKILL DDR3-1600 PC3-12800 4096MBx2 CL9-9-9-24 1.5v, P/N F3-12800CL9D-8GBRL
Motherboard AA number: AA G30742-402 S/N: BTBC219018W3
One other data point: I was able to get the motherboard to power up if I remove and replace the CMOS battery. When it powers up, it shows Code 15 and doesn't appear to complete POST. After this power up, if I power the system off, subsequent power-ups still fail unless I remove/replace the CMOS battery again.
I ended up calling tech support - it sounds like I need a BIOS upgrade. I have a 3rd Gen processor but my motherboard has the BIOS that only supports the 2nd Gen processors.
Scott, the information given by the tech support team is correct. You will be able to see additional information on the following link.
Only problem is that I do not have a 2nd Generation processor (nor can I find one locally) that I can put in to upgrade the BIOS, so I will have to return it to Intel.
Scott, since you do not have a 2nd Generation processor, please contact your local technical department so they can assist you on this inquire. http://www.intel.com/p/en_US/support/contactsupport
Yes, my motherboard is on its way back to Intel already.
