Upgrade to core 2 X6900 on Optiplex 755

[chimtroi]

Hello, I want to upgrade to intel core 2 Extreme X6900 on O755 but mainboard unsupport. Can you help me (Bioc version A10)

May I ask why?
The cost of a X6900 can build you a decent AM3/1156 system.

on screen only notice : system halted,
incompactible processor.
so i can't do anything example as upgrade bios (bios version A10)
Can you help me.
Thanks for all

Because X6900 is a gift from my friend (hic)

The only way you can upgrade the BIOS is if you put your old processor in. Though I highly doubt a OEM Mobo supports 130W EE processors even with a BIOS update.

Thanks for advises. I've upgraded the BIOS to A17 but mainboard not support CPU Extreme X6900.
I upgrade CPU Xeon X3360 then it works good.
