What happens when you put in a cpu that's not supported by the motherboard?

[anonymous x]

I have some crappy motherboard based on the intel 945g chipset (i'm not rich lol), which currently uses a pentium d 820 (LGA775). I am not sure if the early conroe C2D cpus work in it. I want to try maybe a e6600 (ok, that would be hard to find, maybe pentium e series cpus), to relieve some of the bottlenecking for my GPU, but what would happen if the cpu is not supported? anything bad?
according to intel
http://www.intel.com/products/...945g/945g-overview.htm
it supports c2d, but I heard some motherboards based on this don't.
So what would happen if I put in a cpu that is not supported? Will it damage anything?

a few things can happen:

-it will turn on
-it won't turn on
-or it will turn on and give u problems

take your pick!

i wouldn't do it unless you've done some research beforehand

For example my Msi P35 with the 1,2 bios was able to see my E7200 as working at 14 ghz in bios. It also overvolted it to 1,3 V and from time to time it gave me some BSODs. This is a sample of what an unsupported cpu does.

Check for bios updates, there may be one to enables full support for C2D on your board.

And update the BIOS with the Pentium D, before installing the C2D.

Well at that time it wasn't. I really freaked out, since I thought the mobo was damaged or something. But bios 1,8 saved the day.

Worst case: the motherboard gives your 45nm 1.2V processor 1.8V and smokes it.

I've tried this a couple of times, results from the scenarios:

P4 3.06ghz 533mhz FSB in motherboard that supports 400mhz FSB. Powered up, turned on, got in to windows..then bothe the motherboard and power supply went up in smoke. CPU turned out to be ok fortunatly.

Pentium-D 920, in motherboard that only supported 8xx series pentium-D's. Ran fine at stock speeds, but when trying to overclock, increasing the FSB speed, would actually cause the FSB to drop instead. Tried the opposite to see if lowering the FSB would raise the speed, but it lowered it too. Put back the 8xx series, and it overclocked like normal.

Broken period key?(Obviously not)

Anyway, you should have put that up on CPU-Z saying it was a legit OC lol! Highest OC EVAR!

ok thx people

I had a gigabyte GA-RH-775-865 or something, it was their 865 chipset 775 microatx, rev 2.0 that supported C2Ds. I put in a Celeron 440, it booted, but listed the microcode revision level as 0. I flashed the BIOS to one that officially supported the Celeron 440, and it displayed something for the microcode revision level. If the CPU isn't supported by the BIOS with the appropriate microcode patch, then it can crash or do strange things. C2D chips are actually buggy by default, not too many people know that because the microcode patches in everyone's BIOS patch the cpu and either disable buggy features or work around them somehow.

A small wormhole appears approx. 1.2-1.4 meters above the general location of your CPU and kumquats begin raining out from it uncontrollably covering you with their citrusy goodness.

I think in your case it's worth a shot to try one of the older 65nm core2's. Why not try an e2xxx series chip and pad mod it for some overclocking action?

Dude you should take a picture of that and post online along with some pictures of some old motherboard with a copper pipe on top of the CPU socket. Next to it, place a 1.5' tall thermos with the top off, pour some hot water into it, buy some dry ice from publix, and put it in there. Set up a website with adwords, and you'd have a million bucks in no time! Just think, E7200 @ 14Ghz all over the web-- reddit, digg, AT, etc.

it blows up!
