powercycle i9900k ram power cycle issue

[Oh yikes]

We just upgraded our cpu from the i7 8700k to the i9 9900k and it’s power cycling with all 32gb ram in it 

we also did boot it with 2 of the ram sticks in slots b1 & b2

when the i9 is in 

slots a1 & b2 don’t work 

specs before 

i7 8700k

Asrock And Radeon Rx 6800xt

mobo Asus rog strix Z370-E

Corsair Vengeance 32gb (4x 8gb) 3400MHz ram 

corsair 1000w psu

 

so we’re not sure if it’s faulty ram or faulty slots that puts the computer into a power cycle

I'm a little confused. Do those a1 and b2 don't work? Or do they work alone and not with all 4 in? Have you tried updating your BIOS? There is a chance that there could be some compatibility issue.

All 4 slots were working with the old cpu installed

anyway turned out  we had to keep clearing cmos every time we made changes to the ram and cpu config 

cmos kept the previous setup hence why wit was  power cycling
