Striking a fine balance between price and performance. Crucial, the retail arm of Micron, has been selling DDR4 memory at its US store for a while now. Though not present in the UK webstore at the moment, various Crucial Ballistix modules can be purchased this side of the pond through enterprising retailers.

The company doesn't claim to the be the first to market with cutting-edge DDR4 - we have yet to see anything quicker than 2,400MHz on the Ballistix line - but has a well-earned history of reliability and customer service. And with the Intel X99 platform the only one using the new memory for now, one that isn't partial to higher speeds, purchasing well-priced DDR4-2,400 remains a sensible choice.

Playing on this value-performance theme is a 16GB (4x4GB) pack of Crucial Ballistix Sport DDR4-2,400. Identified as part number BLS4K4G4D240FSA and available for $299 in the US and £199 in the UK, the quad-module pack is specified with 16-16-16 latencies. The pricing is consistent with other manufacturers' DDR4 rated at the same speed and timings.
