Let me ask the question has long interested me.

My IP ASUS P5Q3 Deluxe. The description card says that it supports the standard memory of 6400, 8500, 1333, 1600, 1800MHz (2000 MHz frequency is not a document) and here the most interesting. The following position description says that the documented supported memory types 800MHz and 1066MHz. And here the question, and that the description has been before, where the talk about 1333, 1600 or even 1800MHz - commercial progress, advertising or ... 1333, 1600, 1800 - it did maintain standards or as a supported or conditionally supported, but they work no promises?

Go to the BIOS and the opening line of DRAM Frequency (with spelling may be wrong) that actually see - supported by the standards of DDR3-800MHz and DDR3-* 1800 * MHz (interesting that in the marking mean "*....*" asterisks).

In a word riddle, to help solve that and I ask the forum participants.
