Corsair's new XPERT series is the world's first line of memory modules that monitor parametric data of thememory real-time! Corsair XPERT modules use an integrated microcontroller to measure Voltage, Temperature, and Frequency on the memory module. Each of these parameters, along with a user-programmable scrolling marquee are shown on a big alpha-numeric display. The TWINXP1024-3200C2 is a matched pair of 512 MByte, ultra-performance DDR SDRAM modules that is designed for exceptional performance at high clock speeds and low 2-3-3-6 latencies. Each module includes a high-efficiency cast aluminum Corsair heatsink and 24 activity LED's that show the level of memory activity on each bank. All Corsair TwinX modules are tested as a matched pair in a dual channel motherboard and packaged together immediately after test.
