i'd keep them. Even the Elipda's do atleast 900 mhz. I got to play around with my friend's lowend system I built, Foxconn 965AA, 1gb Adata vitesta. That Vitesta is known to have elipda chips, but it hit 450-460 FSB 1:1 ratio. Not bad... 900, 920 mhz on elipda's on a crap ass motherboard? I don't think that was the limit either, since the motherboard was really flaky when we started overclocking.
