Based on the Technical Product Specification of this board, the bios revision is version 0023. This is the reason why your system is not posting when using the processor in mentioned.
The LED pattern you get from the system, means that the system is not posting and not necessarily due to a Memory issue. This issue can be fixed by updating the bios on your system by using a 2nd generation processor and then the 3rd generation processor will work just fine. The correct way is to install all versions after the 0023 until you get to the 0039.
