Question ASUS Maximus VII Hero is not recognizing all the RAM after adding a new SSD ?

[holmes777]

I'm stuck hope you can help out cheers.
So I read on here a post about putting a new SSD in the old motherboard in title, so I bought a PCI adapter and put 500GB drive in PCIe2.
All worked well, booting up ok, except not recognizing all my RAM now.
Before adding the SSD, I had 2x8GB corsair cards in the 2 red slots (pics attached), and it was picked up ok in OS as 16gb total, all was well.

Now the system will only accept, boot up, and 'see' 1 x 8GB memory card in DIMM_B1?
If I put the both cards in the red slots like I had it running before, and as in the manual, pg 1-10, it wont boot at all, powers down immediately.
I have the both cards in B1 and B2, only way it will boot, but it only sees one card in B1 in the OS.

Welcome to the forums, newcomer!

You should host your images on a site like Imgur or their ilk then pass on a link to the images here.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Did you clear the CMOS after making sure your BIOS flash was successful?
