MSI RTX2070 artefacts on load - replaced rams still bad

[ktmmotocross]

I have this rtx2070 that have artefcts on load. mats show maybe two chips. after replace C1 and D0 chips it shows oposite chips. im confiused. is that because of MICRON ic? i know they goes bad in mass but this oposite errors confuse me

MEmory ic is D9WCW

after replacing A0 and B1, error switch bck to how it came. WTF?

i think that GPU balls is bad. errors gone just on side where i solder
