The engineers at Alienware will only vouch for triple channel memory. I agree.
You can easily upgrade your mem with 3x2Gb or 3x4Gb (max recommended) pc3-12800/1600MHz.
Or. Faster 1866Mhz @ 3x2Gb max. Some 1866 triple channel kits boot with the XMP profile enabled, some don't. If not, assign it to run @ 1866: turn off xmp profile in the bios, set multiplier to 14, bump uncore volts +200mv to get them to boot. That usually does it. You can scrounge the forum for similar advise on faster 1866 modules. related posts on 1866 mem:
2x8gb prob'ly a bad idea. 3x8gb prob'ly a bad idea too ... 3x4gb max of 1600MHz, or 3x2Gb max of 1866MHz ... anything else is a risk ...

I'm trying to help you out here. You have 3 memory slots. Don't be surprised if by populating only two slots, your double data rate ram won't run at top speed in a dual channel mode setup, (as opposed to tri channel mode). You would have to search to see if the Intel x58 processor can run memory in only dual channel mode, as opposed to tri-channel as it's designed to run.
The MSI-Alienware board is only rated at 6Gb max of 1866 memory, so, like I said, pm the guy who just tried 3x8Gb at 1600mhz. If his didnl't work at 1600MHz, how can you expect yours to run at 1866? If his did run at 1600mhz, do not be surprised it's because he used 3 memory cards, not two.

Currently I have 30 4G at 13th and I want to increase to 16gb 2x8gb at 1866mhz hopefully.

12gb 3x4gb at 1333mhz. Darn auto correct.
