As it was announced a few days ago, OCZ Technology is among the first to offer memory modules specially designed to work with Intel's X38 chipset, equipped with Intel's Extreme Memory Profiles (XMP) which allow overclocking straight from the OS:

"It is truly a milestone in personal computing to see Intel support overclocking," commented Dr. Michael Schuette, VP of Technology Development at OCZ. "The new Extreme Memory Profile options on the new OCZ DDR3 modules allow the end user to select extreme or ultimate performance through a framework of predefined and validated optimizations of individual settings without the hassle of manually adjusting each single parameter. Moreover, the predefined settings also adjust parameters that are not accessible to the user in most CMOS setup utilities. What this means for consumers is easy overclocking on Intel platforms right out of the box."
This new XMP-Ready memory will be available as OCZ DDR3 PC3-12800 Intel XMP Ready Titanium Edition (1024MB) modules running at 1600MHz in 1GB or 2GB kits, configured to run 8-8-8 latencies, but will come with a second profile featuring 7-6-6 latencies. It's interesting to see OCZ back these overclockable modules with their usual lifetime warranty. No word on pricing or availability yet.
