What a deal from Geeks.com:

http://www.geeks.com/details.asp?invtid=2GBDDR2NB6400-MICSYS&cat=RAM. I purchased 4 GB for my new Dell XPS M1330, which is shipping today. Total cost including shipping: $156.46, or $39.12 per GB. Cost on the Dell.com website to upgrade from 2 GB to 4 GB: $375.00, or $187.50 per GB. Percent savings: 79.2%.

AND, the new memory is 800Mhz, whereas the Dell memory option is the slower 667Mhz.

Yay.

UPDATE: I just discovered that the Santa Rosa chipset, while showing a “800Mhz FSB” option, will underclock the 800Mhz memory down to 667Mhz. The FSB apparently is the bus to the CPU, and doesn’t refer to memory speeds. Who knew? Crucial.com shows me the 800Mhz option as the “Best” option for my M1330 using their online configurator.
