Phoronix has posted a review on the Corsair XMS2-5400UL memory
Although Corsair's XMS2 TWIN2X1024-8000UL memory modules, which are rated for 1000MHz compatibility on Intel-based motherboards,Corsair XMS2-5400UL Review
have taken some of the spotlight away from their famed TWIN2X1024A-5400UL modules, these DDR2-667 modules continue to be popular with enthusiasts due to their cheaper price point and phenomenal overclocking abilities. While sticking to its DDR2-675MHz speeds the memory can run at impressive 3-2-2-8 timings, and when loosening the timings they can breach the 1GHz barrier. Of course, none other than Micron's "Fatbody" D9 ICs powers these modules.
