I have a motherboard meant for a processor with a max of 10 cores. What if I installed a processor with 15 cores?

They're both from the Xeon E7 family.

Well it depends. It could just not turn on at all due to bios incompatibilities or If the 16 core draws too much power than you could blow up the VRMs of the mobo.

Motherboard name would help a lot.

The cores it's intended to run draw 105 W each (4 processors total). If I plugged in 2 processors (the 15 core ones) that draw 130 W each, would this be a concern?

It's a IBM/Lenovo x3850 x5 server with a 88Y5351 IBM motherboard.

That is an OEM server board so you may very have bios issues if you drop an out of spec processor into it.  Those types of boards would be a lot more temperamental about what you are socketing then a retail board.

 

If its part of the existing supported processor family it may work but there would be no guarantees.

I don't know if the VRM's are socket specific or not and I cant seem to find the information. If you have the CPUs already then sure try it out but if you don't try to find CPUs that are compatible with the mobo.

I would not expect any chips other than those listed on the supported CPU list to boot. ESPECIALLY those with more cores.

however, 4 sockets at 10 cores a pop should be plenty for anything you plan to do.
