A-DATA Extreme Edition 1200+ 1GB Kit Review
A-DATA is joining the band wagon of 1200 MHz memory with their Extreme Edition memory. Many manufacturers have displayed memory at these speeds at Computex this year. The kits are available in 1 or 2 GB variants and come with the new, cleaner heatspreader. This Extreme Edition memory is the first to manage 1200 MHz at default voltage with no problems at all.
