Kingston, the life time warranty ram maker delivers its DDR3-1800 memory modules for the P35, X38, X48 boards that features the low voltage DDR3. We managed to loan a pair of 1GB to test it on the Gigabyte P35T-DQ6.
This pair of modules model KHX1440DK2/2G is rated at PC3-14400 or DDR3-1800. There are 3 different SPD timings for this module ranging from CAS 7 to CAS 10. As you are probably aware, when operating at higher frequencies, we have to run at a higher CAS latency. In this case, at DDR3-1800, it actually runs the modules at CAS 10, 10, 10, 31, 2T. The module is rated 1.9v.
In the next few pages, we take a look at the benchmarks of the modules as compared to a pair of Samsung that runs at CAS 8 DDR3-1333. WE will be able to see if the modules, when paired with a QX9770 will improve with running at DDR3-1600.
