Also check out MWAVE for the 1.8V DDR2 667. NewEgg may not be the lowest deal. MWAVE does not carry the Kingston N5 DDR2 800 RAMs. Also note that Kingston will also sell cheaper non-N5 DDR2 800 RAMs. These will often sell at a lower price. You can often identify non-N5 with the blue plastic container. If you cannot locate Kingston N5 DDR2 667 or 800 RAMs, then go with 1.8V DDR2 667 or 800 RAMs from Crucial.
