Unless you have a SM52X module in the lower slot, this will give you dual
51's and leave you with 4 slots open.  Darn rare though.

Are the mainboard and RAM card on the same P2 segment?  That will be the
deciding factor, and the x60 chassis has 2 P2 busses (slots 1-7, and
10-12).  Slots 8 and 9 do not have the P2 connectors bussed to anything.

The x90 chassis busses 1-7 together, 11-12 together, and 13-15 together.
There should be nothing unusual about the x90.
