Among the first and most important things: read the documentation over at
www.support.dell.com for 'replacing the cpu/processor' to familiarize
yourself with what's involved.

Secondly, you'd best have a steady hand and careful eye with regard to the
CPU socket pins. One minor bump, drop, or rub and your motherboard is a TV
tray.

With this board, there's less concern with frying the mobo than there is in
*damaging or bending the cpu socket pins*. That's what I meant by one
dropped screw, cable, or the cpu itself (into the open socket).

Good luck. Glad you found the info. you wanted.

Nope. The newer Intel multipliers are locked, even in homebuilt systems so
it's not a factor.

In theory, she should be able to drop the new CPU in, boot into BIOS to
verify and go. About the most she might need would be a BIOS flash - and I
don't think that's the case (and I'd even try the chip FIRST before
flashing).

The clock speed will automatically change in BIOS when the new chip is
added.

I once saw a 2.4GHz/400mhz Celeron that believed it was a 3.40 (or so) with
a 667mhz FSB At least that's what the CPU was telling BIOS. Ultimately
was a bad power supply.
