problem cpu upgrade i5-3330 to i7-3770

[robbro]

I previously read comments suggesting I can swap out my i5-3330 cpu (in Dell inspiron 660) and install i7-3770 without changing the bios, (or anything else).
I picked up a Dell Optiplex 9010 SFF has i7-3770 cpu.
Both my Dell Inspiron 660 and Dell Optiplex 9010 were working nicely.
I removed the i5-3330 cpu from Dell Inspiron 660 and installed the i7-3770. Applied new thermal grease, and that's it.
I can turn the unit on and off using the switch, the activity light indicates the cpu does run through it's processes, but no signal to my screen.
I haven't changed any drivers, all I have done is swap cpu's.
They're both 3rd generation Intel and both computers are Dell, as I said.
I haven't tried installing the i5-3330 into the Dell Optiplex because prefer not to get involved working on the 2nd computer until I establish the eventual result with the first one.
So far the suggested easy swap has not materialized.
Do I have to replace the old cpu to update bios?
Do I have to replace the old cpu before I can (hopefully) fix this some other way?
I'm hoping someone who actually understands what is required here will be so kind as to step in and help me out with some proper guidance (cause I'm lost).

Thanks, So stuck!

PS - The 660 is running Win10 Home; 16GB PC3L12800; EVGA GeForce GTX1050Ti; 1TB hdd if that matters.

Motherboard for Inspiron 660 is: Vostro 270 MIB75R/ MH_SG MLK 11068-1
Dell Optiplex 9010 SFF Small Form Factor DDR3 Motherboard System Board Part No: 51FJ8
I don't really understand how to compare these motherboards, what I was going by is:
Both cpu's use Socket LGA 1155
Both 77Watts

The 660, according to Dell's data sheet, only shipped with Celeron's, Pentium's, i3's or i5's. No i7 option.

Usually, with OEM systems, CPU support (via the BIOS) is limited to chips that would've shipped from the factory.
Might be worth ensuring you're on the latest BIOS, on the off-chance it brought in further CPU support:

Looks like only A11 is available.


I assume the board is made by Foxconn or similar? Might be worth heading to the OEM site to see if there's anything on offer. You'll need to know the specific model of your motherboard though, hopefully it's printed on there?

If it's a Foxconn, you'd need to identify if it's any of the ones they provide support for.

Per your reply I identified the motherboards. I added the cpu sockets and wattage, which are a match.
I didn't understand how to compare the motherboards if the cpu requirements are the same. I took considerable time to research all I could figure out about generations, sockets, wattage. It all looked like a go until I tried it and now I found the below:
I just noticed on Dell site someone stating: "No i7 Series processors are supported by the Vostro 270, only the i3 and i5 processors are supported"
> SO MUCH FOR BELIEVING WHAT YOU READ about easy upgrades!!!!!

Yes, "socket compatible" does not necessarily mean it'll just "work" - especially from OEM setups.

Consumer retail boards, if a socket compatible chip is not supported via BIOS rev.1, chances are good an update will be provided to enable support.
OEM's though, only "support" their product. Their product is what ships from the factory(ies). If they only sold an i3 and an i5, that's all they expect to be run in those boards.

Barty 1884 thanks for your help. It took a while for me to locate the exact answer to my delima, however, you were on the right track from the beginning.
I hope this post helps other beginning builders by shedding some light towards how this type thing sometimes works and how you can be fooled.The post I read on tom's suggesting in his opinion this conversion seemed like it should be pretty easy sounded good so I believed it.
Seems someone on the Manufacturer's forum community (Dell) posted the answer for someone asking about swapping these cpu's, saying the motherboard will not support i7 but I didn't see it.
I did my own research, spent time gathering a lot of information that seemed to make good conclusive sense but ultimately it didn't work as expected. Chalk it up to experience. I learned the hard way on this one.
Thanks again for your help.

Glad you found the solution
