Hi Mr. Lapagr,
Please, can you send the details of your finally choose?
Please, can you send the links to buy the same memory banks?
I have the same computer, Dell Precision 390, SSD 250GB (new), 3GB memory ram (2 modules, 1+3GB) of exacly the same model, Nanya pc2-5300E-555-12-G1, so please, reply asap!
just install non-ecc banks, as long as its ddr2 it doenst matter which brand you put in, you can even use different brands in one pc.
ps. Ive ditched the 390 because the bus speed was just too slow in the end, now Im using a T3600 which works like a brand new shiny charm.
