That article is the truth.
I recently read an article in Custom PC Magazine where they compared around thirty types of memory and the results were really quite an eye-opener. Some makes of generic RAM are just as good, and often better, than their more expensive peers.
Having said that, in short, generic RAM cannot be trusted, unless you know what you're buying and what chips have been used during the manufacture process.
Expensive RAM, such as Kingston and Corsair, is better for overclocking, but you will pay a premium for it.
If you're not overclocking and running stock, read articles such as the one linked to here and make an informed choice, you could save yourself a lot of money.
Even 'standard' RAM will overclock a little, I regularly run Crucial and Corsair Value Select at 220 FSB and higher.
Crucial can be trusted.
DON'T EVER buy Generic RAM unless you've checked out a few reviews, there is some truly awful stuff out there.
And finally - good luck in your choice
