I have an HP Probook 6570b, Motherboard is Hewlett-Packard 17AB (U3E1) with HM76 Chipset, rPGA988b Socket and CPU is i5-3210M.
This is a list supported CPU's, but it's a support list for the HM76 Express Chipset, and not a support list for Motherboard's.

Can I upgrade to i7 Quad, preferably i7-3840QM?
I've read that people with QM77 Chipset were successful, but what about HM76 Chipset?
