RAM Slot Splitter?

A friend of mine said he opened his bosses business pc and found an unusual presence inside. This pc was custom made by an unknown person but the boss apparently handed said builder a wad of cash and told him to make the best one he could. the specs were a quad core extreme (unknown GHZ), sli-configured geforce 8800GTX's and 16Gb of ddr2 Memory over four slots. Nothing unusual about this as 4gb sticks of ram are becoming available, but my friend described it as not using 4gb modules, but rather 8x2Gb modules connected to the 4 slots via some sort of dual-slot adaptor!
Now i don't know if my friend was BSing me or not, and have not been able to find any search results indicating the existence of such a part, so can anybody tell me if they exist and if so provide me with information regarding their impact on system performance?

Ummm, no. A 32-bit OS can handle a total of 4 GB of RAM, but taking into account RAM on video cards, and caches, this usually amounts to 3-3.5 GB system RAM. A 64 bit OS has a theoretical limit of 16 exabytes, but Vista limits this. Assuming it is Ultimate, the limit is 128 GB.

He could be confused by something like the Gigabyte iRam. This would allow more sticks but they would not be part of the regular system memory. I don't know anyone who actually uses one of these though.

yeah i thought as much. in my searches i came across the iRam solution, and as far as i saw its more a fast storage medium rather than more ram. I suppose readyboost could easily make mince of that theory though. and eklipz, sad you have to downplay other peoples intelligence to feel special. How about using your quick-wittedness to come up with actual solutions and answers?
