Another sad thing was that I read that we can expect DDR4 prices to keep rising for the next year haha soon only millionaires will be able to afford it

yes sorry to confirm

you need to grab the 2933 'cl14' kit to make sure its the b dies

they should have other kits with b dies ,but searching the part number would have to be done to confirm (2993 cl14 would just not be possible using other chips)

at the other end of extremes the 2133/2400 flarex stuff could indeed have hynix or samsung d/e/s dies

that is in fact a kit of four 8gb cl 14 samsung b dies yes,
two points to note

dont trust the rgb software, it was corrupting the firmward of rams early ryzen stage (i really would advise non rgb myself)

and second, we already did have a guy use 2 x 64gb kits and it worked fine, but in theory
technically you should only use a matched kit (in practise it seems not so life threatening)

you may well find though ,its a case of install 2 stick in dual channel
update bios,install windows
and then adjust manually ram timings fine tuned to your board before dropping in the other 6 sticks with fingers and toes crossed

ooops yes my mistake

64 divided by 4 would be 16 not 8

sorry mind is elsewhere today
