To install the Intel Core 2 Extreme quad-core processor, you will first need a motherboard that is compatible with the CPU. Whether it be through a bios flash or a motherboard that is designed to support it is of extreme importance. As you can see, I first chose to use the Abit IP35 motherboard which I thought was compatible with the processor, but I was mistaken and later found that at this time, only the Abit IP35 Pro support it. I then tried my DFI Lanpaty 680i LT, but ended up crushing the resistors on the rear of the board installing the Thermalright Ultra90 heatsink. So finally with a bios flash, I was able to utilize my DFI Lanparty UT P35-T2R.
If your motherboard needs a bios flash in order to run the QX9650, I would suggest flashing the bios prior to installing the processor, all three boards (Abit IP35 not supported) would not even post prior to a bios flash. I had originally chose to use the Thermalright Ultra 90 heatsink on the DFI motherboards because of their preinstalled NB heatsinks. My Zerotherm fan without a mod will not mount unless the fan itself is facing upwards, but since I had already crushed the resistors on one DFI board with the rear plate of the Ultra 90, I decided to use the Zerotherm heatsink facing upward. It comes with an X bracket where the other has an oblong bracket.
