Hi guys, i'm looking to pick up some ram for a 2740p and was wondering if this would work: Scan.co.uk: Corsair Memory 4GB DDR3 SO-DIMM PC3-10666 (1333) Dual Channel Laptop - CMSO4GX3M1A1333C9 What do you think of that module? is it any good? Also, the system i'm buying in the uk has 2gb of ram (i'm guessing it will come in 2x1gb sticks) so i was wondering if I should buy 2x 2gb sticks and chuck out the 1gb ones.. OR stick in a single 4gb stick keeping one 1gb one. i.e. giving me 5gb in total. I'm assuming that the latency of the 1gb sticks will be higher than that of the single 4 and so might be a bit slower, but i was just wondering if drawback of latency would prevent the 5gb system working as fast as the 2x2gb (4gb) system. what are your recommendations? thanks!
