asrock 870 extreme3 r2.0 not seeing 32GB Ram

can you not return the hyperx and just get one set of matching ripjaws ?

i have the same set of hyperx here in a phenom 965 system
(and im really not impressed by them, i know they wont run 1866 on phenom but then they also wont run at phenom2 speeds without major tweaking)

however there is another scrap of info i have just chanced upon
with a fx6100 and 4 ram slots occupied max ram speed is 1600 for single sided ram and 1333 for dual sided ram

humour me if you please
boot the system with just two hyperz sticks
check its running at 1833
next enter bios change ram speed to default OR SET 1333
then instal the 4 sticks of hyper and see if it boots then when they are downclocked

heres the link with the graph as first post and the rest of replies generally agreeing the memory controller is struggling

Yeah, sorry, should have mentioned that I've done that, allthough I checked them as pairs. Both pairs showed up as 16Gb.
Also checked the slots to see if A or B were defective. All ok.
