what is the different 667 and 675

[imported_WBStrip]

I am looking at memory and I see that there is pc2-5400 ddr2-667 1gb and then pc2-5300 ddr2-667 1gb then they have pc2-5400 ddr2-675 1gb are they all the same or what. The new MB that I am getting uses ddr-667 would all of those work

They are all the same. It is because the memory clock is a bit of an odd number, and manufacturers classify the speeds independantly, so there is no clear standard. Just know it's all DDR2-667.
