Question I am greatest looser! Cannot get Ryzen 1600 stock heatsink to re-affix.

Disassembled to install NIB 3600. Backplate dropped behind rear panel. Spent 40 minutes getting it all back together. Weirdly, it did not work. Also, normally, resting the 1600 (Wraith Spire?) heatsink on the installed CPU, normally, it will sit down far enough, that the screw-in pins will sit just inside the posts of the backplate. Wondering if my CPU heatspreader is thicker than normal. Are faked AM4 (AM2+?) CPUs normally thicker?

I noticed that the BIOS version on my gigabyte AB350 gaming 3 atx board called out F40 for Zen2, and I'm still on F25.

Don't know what possessed me to start the physical upgrade before ensuring that the BIOS was updated.

Gonna order a new cooler, one with a half-sane own backplate.

First off, dropping the backplate behind the rear panel is a total pain, I feel your pain on that one. Did you manage to get it all back together properly, and did you double check all the connections? If it's still not working, there may be something else going on.
As for the heatsink not sitting down far enough, that's definitely odd. I'm not sure about the thickness of faked AM4 CPUs, but it's possible that your heatspreader is thicker than normal. Maybe do some research to see if there are any compatibility issues with your specific CPU and motherboard.
And lastly, it's always a good idea to make sure your BIOS is up to date before starting any upgrades. But hey, we all make mistakes sometimes. Maybe now is a good time to update your BIOS and see if that solves any issues you're having.

Why not a 5600? But yeah, update the BIOS first on that board.

You are neither a looser nor a loser Larry.

On the bright side: This thread can serve as a reminder, that no matter how many builds someone has done, one should always observe a well developed methodology based on best practices. When you get sloppy, it can cost much more time, effort, and potentially money.
