UPgrading ram

Hey folks. I was curious if anyone has tried these http://www.newegg.com/Product/Product.aspx?Item=N82E16820231192 Was looking at upgrading. Seems like the heat spreader maybe a tad bit to tall.

You could get these or these

They're all essentially the same sticks imo, just different heatspreaders. Notice how its 2-2.1v for the ones you linked to get to ddr2-800 @ 4-4-4-12, you could probably do that with the other sticks i linked at the same voltage.
