PQI Turbo Memory PC4000
 

Description: Today PQI (formerly known as PMI) brings us their Turbo Memory 1GB PC4000 DDR dual channel kit. It's rated at an aggressive 2.5-3-3-7. It used to be that if you wanted PC4000 memory, you'd have to give up your latency to do so. This appears to no longer be the case with PQI's new PC4000 sticks.
