F4-3200C16Q-16GRKD and F4-3200C16Q-16GRK problem with XMP

Hi

i need some help. i used 2 sets of 4 x 4gb ram from GSKILL. it has always run fine. Some days ago i had to change my CPU waterblock AIO. Since my computer refuses to start with XMP 3200 profile. the mainboard shows a "bd" Q-code. i changed the waterblock with real caution.
the 32gb are detected no problem on that. i don't understand how a simple waterblock change can produce so many trouble.
Please help me.

my hardware :

ASUS RAMPAGE V EXTREME
INTEL CORE I7 5960X
AMD RADEON R9 200 SERIES
ASUS ROG THOR 1200W - 80 PLUS PLATINUM (brand new)

i tested each ram module with XMP enabled and each of them shows 3200MHZ.

Hi. maybe this will help users like me. So i changed my waterblock AIO for a CORSAIR Hydro 115i RGB Platinum. Seems that the ASUS RAMPAGE V EXTREME with latest bios has some issues with this hardware. the waterblock has an USB connector.
I decided to downgrade the motherboard bios and…. it's working fine now : 3200mhz ram.
i ran some programs like MEMTEST, CPUZ and FUTURMARK to stress the all system for some hours : everything is fine and temperatures are completely ok.

Best regards
