System not getting past post with Ram in slots A1 / B1 after reseating CPU cooler

Recently when I turned on my computer I got a Q-code 55 memory not detected. I checked to make sure that my CPU cooler was not overly tightened, reseated both my CPU and cooler then turned on my system and got Q- code 55 again. I tried the following combinations with my memory

G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200
https://www.newegg.com/Product/Product.aspx?Item=N82E16820231902

Slot A2 / B2 - Q55
Slot A1/B1- Q55
Slot A1 - single stick q-55 with both sticks
Slot A2- single stick q-55 with both sticks
Slot B1- single stick both got past post booted into windows
Slot B2- single stick both got past post booted into windows

Before my system had been running perfectly with the memory in A2/ B2 running at 3200MHz. I used the USB Bios flashback to update from 1701 to 3401 to solve any potential new issues and also to reset the Ram speed to default. I tried all the combinations of Ram slots again with basically the same final results except this time
when the system failed to post it would cycle through Q-codes 01-03. With a single stick of Ram in either slots B1 / B2 I can still get past Post and boot into windows. Any ideas on what I should try next I'm out of ideas?

I did the CPU looks like its in perfect condition. My problem is almost exactly the same as the one described in this post so it seems like its not unheard of
