O/T: But somehere knows - i3-3240 vs. i7-3770k

A friend tried to upgrade his Intel i3-3240 machine to an Intel i7- 3770k.
It did not
work. (Would not boot)...

What we can’t understand is that if both are 1155's and Ivy Bridge
why would they not be interchangeable?

Because the MB was not designed to run that CPU ?

Is there a later BIOS that will support the i7-3770k by any chance?

BIOS microcode support (amongst other things).
The BIOS contains on the order of eight microcode
patch files (around 2KB each). A new processor,
won't have a file for it.

The BIOS spends way too much time staring at
the particulars of the processor.

On new Asus motherboards, you can now flash
upgrade the BIOS via the white-ringed USB
port on the motherboard I/O plate. The advantage
of this feature, is it uses no CPU to update
the BIOS, and if the motherboard arrives with the
wrong BIOS in it, you can flash it up to a
version that supports your CPU.

Not every company offers "CPU Support" charts.
For example, with a Dell, you might not have
any clue as to what a particular motherboard
is good for.

With retail Asus or Gigabyte or MSI motherboards,
you're bound to find a "CPU Support" web page for
each motherboard model. And from there, you'll be
able to figure out what BIOS version is needed.

In the old days, you'd buy a $39.95 Celeron, to run
the motherboard long enough to flash upgrade it.
It would be either that, or get a local shop to flash
it up for you.

*******

Sometimes the issue is the VCore max power rating.
On cheap motherboards, you can buy a motherboard
that will only run 65W processors. No 89W or
125W processors should be used. The CPU Support
chart sometimes lists the power rating of each
CPU, and reading between the lines, you can
soon come to realize the motherboard is a
"lightweight" and that's why the CPU isn't
supported. It doesn't have a good VCore.

*******

Provide make and model number details (preferably
motherboard details, but if a Dell, the machine
branding and model number will have to do).
For a Dell/HP/Acer and so on, info will be
very hard to find. So don't expect miracles.

*******

And make sure you plugged back in, the ATX12V 2x2
power connector, the one with two yellow and two black
wires. The CPU cannot start, if you don't plug that in
again.

You describe the CPU, not the motherboard. Give the brand and model
(and version) of the motherboard for anyone to provide you with
non-vague or focused responses.

Did you look at the mobo maker's web page on that model to see what CPUs
it lists as supported?

Did you check if there was a BIOS firmware update to include support for
CPUs other than those listed as supported on the product web page?

Did you reset the CMOS copy of BIOS settings (i.e., clear CMOS)?
