You'll then need to work out how to enable the Enhanced Memory Profile in the BIOS myknownself, and of course other tweaks as well to get it stable and optimised.
There was a pin that was bent up and curled over itself making a loop.
No idea how that could happen short of magnification and grabbing it with tiny tweezers and rotating. It took a microscope to be able to see it correctly.
There were a couple of pins slightly out of place as well. I was careful putting it in and closing the latch but it's possible I moved some. But there's no way I can imagine I possibly curled that one back on itself.
