Mid 2011 upgrades

[Aaron55]

Hi there, i have a mid 2011 21.5” iMac and I am going to be upgrading my CPU, GPU, and Hard drive. My question is, after installing these things what do I need to do software wise other than install my operating system? I have heard something of “flashing” my new GPU but I don’t know how to do that. Any advice would be appreciated.

New hardware: CPU- intel core i7 2600S, GPU-Nvidia K1100M, SSD- Samsung 860 EVO 500GB

Concerning the K1100M, check the GPU thread.
No special requirements for this CPU, or the SSD. There are different ways to address the fan spin-up (dependibng how you connect your SSD / old HDD), check one of the other threads here in the forum.
