Has anyone successfully upgrade their Dell Precision M6300 - CPU to 

Intel® Core™2 Extreme Processor X9100 (6M Cache, 3.06 GHz, 1066 MHz FSB)

I know that you can upgrade to 

Intel® Core™2 Extreme Processor X9000 (6M Cache, 2.80 GHz, 800 MHz FSB)

I am concerned that because of the 1066MHZ FSB on the x9100 the CPU will not work.

However I  would love to hear from anyone that has tired with success or tried and it did not work

running BIOS A14

Thanks in advance
