I got 1gig of ram, in the form of 2 512 sticks. A week later I went to the same store, and got another 2 sticks of 512 and asked him to get the exact same kinda ram. In my Nvidia control panel, under system information, it identifies the 2 origonal dims as Kingston, but the 2 new ones are unknown =(

Heres the comparison:

Origonals:

Memory type: DDR SDRAM

CAS 2.5:
Cycle time (tCYC) = 6.000 ns fMax = 166.667 Mhz
Access time (tAC) = 0.700 ns fMax = 1428.571 MHz
CAS 3.0:

Theres even slight visable differences in the dims. Should I try and get my money back and the get right stick or am I just freakin out and this is just a slightly modified version of the exact same stick?
