Not all my RAM is showing up...

So I have the stock 2X1 and 4X2 aftermarket.
None of the sticks that I put in the second riser will show up.


I tried the 2's in A1,A2,B1,B2 then the 1's in A3,A4.

I then tried the 4 2's in riser A and the 1's in riser B.

It didn't seem to matter, all that would show up is what was in Riser A.

Could it be a bad riser or something?

Both risers have been in & out several times.

I thought default position was A1 & A2?

Any red lights on the riser? red lights mean a bad chip or bad riser.

Ah, there is indeed a red light on on riser B. It's there regardless of which modules are in it.
Diagnosis: bad riser?

OK, so I put the stock sticks (stock sticks?) only in, A1 and B1, and they both show up fine.

I put all 6 sticks in (A1-4 B1&2) and neither of the B riser sticks show up.
Closer inspection reveals there's a bright red light on on the riser next to the DIMM 2 label on the riser.

If the second slot on Riser B was bad, would that cause both sticks in that riser not to show up?

yeah, hardware test confirms it.

note to self: in the future, just run the stupid hardware test first.
