Upgrade possibilities:

[Admiral Huddy]

I was wondering if the following Dell PC could be upgraded to a C2D, say a Q6600?

Current CPU: Pentium D 920 Presler, Socket 775 LGA
Current MOBO: Dell, 0FJ030, i945P chipset.

I'm pretty sure it can with a BIOS flash but I'm not sure of any Dell constraints on upgrades.

What do you think?

check to see what bios upgrades are available and what they support - should give you an answer.

Dell support page provides no BIOS release information

It is unlikly, most 945 boards required vrm updates to take Core based CPUs.

This. And I can't really see Dell putting up new BIOSes with Core 2 support for their 945 boards.

[Edit] If I really wanted to know, i'd get something like an E6300/6400/6600, pop it in, and fire it up. If none of those three work, you won't have Core 2 support.
