It's always difficult to make absolute recommendations based on the results obtained from a couple of modules. However, if the performance of the sample pair are representative of the vast majority of Crucial Ballistix PC4000 modules, I'd have no hesitation from recommending them to a wide range of enthusiasts. The test pair seem to break the long-held belief that high-speed RAM, along with associated high timings, cannot be run at moderate speeds and extremely low latencies. Priced at around £190 for a 1GByte pair, Crucial Ballistix PC4000 modules sit alongside equivalent modules, in both price and specification, from the likes of Corsair, OCZ and GeIL.
