Anyone who wants to get the maximum performance out of his netbook or laptop, makes the latch nothing wrong. The 800MHz-bolt was easily detected by two devices (N220 and 1000HE). Flap screw, bolt out, Corsair pure, flap, finished! Was immediately recognized. The bars do not differ on the speed, but Corsair's lifetime warranty and the price is good (~ 40 Euro). For memory-intensive applications (many tabs in the browser, instant messaging, office, music program, image editing, etc. at the same time) definitely added value. Programs start noticeably faster, especially when they were used before.
