Ok thank you. Do you know where I can download that part of bios? I just flashed my bios with a download I got from here right b4 I attempted CPU upgrade. Also … Could it be that the CPU says "CORE 2 EXTREME" on it instead of CORE 2 QUAD?
USFF does not support Quads. Basic Reason 150W power supply is not enough power. Core 2 Extreme QX 6700 uses too much power (130W) and is not supported in ANY 755.
ooooooooooh **bleep** I didn't know mine was a USFF so I didn't head that section of chart.. **bleep** I guess that was a waste of money.. Dang it …..thank you for ur help.. Wait if I get a bigger PSU, will it work then?

That's weird ... it should have worked. These are Conroe chips.
I've swapped an E6600 for a Q6600 (slightly slower Q6700) before on a couple of Dell XPS-410 and once on a ASRock ... worked fine.
Sounds like maybe OPTIPLEX 755 is missing BIOS microcode for Q6700.

There is no conversion sticker this is not a XEON based board.
