I recently bought a Kingston 2Gb (2x1Gb) RAM. It was DDR 400 (PC3200)...but when I put it into my computer, the system only read DDR 333 (PC2700). So instead of having 400MHz computer speed (which I ordered and the package DOES say 400MHz), I got 333MHz. Is it really worth the hassle dealing with Kingston to get the DDR400? It's all the same price, but I want my computer to run at its max. Before this, I had 1 stick of 275MB RAM, 400MHz, so I do have a faster computer. But being picky, I expected the 400MHz computer speed that I ordered. Does the extra 67MHz really make that big of a difference?
