Source : http://www.xbitlabs.comwhile some memory manufacturers have already released DDR3 modules clocked at 1.8 GHz, Intel is currently working with JEDEC to increase RAM frequency even higher with 1866 MHz and 2133 MHz DDR3 modules. Santa Clara's giant wants also to enable such speed-bins via its extreme memory profile (XMP) technology:
We are working on adding a few more speed bins to JEDECs standard DDR3s definition specifically like 1866MHz and 2133MHz even though these speed bins will first be covered by the XMP spec, said Christopher Cox, senior staff engineer for Intels platform memory operation
DDR3 is planed to replace current DDR2 in next generation Intel platform, providing larger bandwidth and lower power consumption (1.5V vs. 1.8V for the DDR2). This is to reduce the resulting higher latency that Intel wants to increase DDR3 frequencies, as well as DDR3 overclocking feature via XMP.
