As you already know a number of motherboard manufacturers are offering eight DIMM slots on their upcoming Intel X79 motherboards. We have seen half a dozen different boards at IDF 2011, but not too many of them are running any demos. The one demo that we ran across that is impressive was at the Kingston Technology booth. Kingston is has a system up and running using the Gigabyte X79-UD5 motherboard and it has all eight DIMM slots populated with 8GB DDR3 memory modules. This means that the system was running 64GB of memory! Kingston said the memory was rock solid and to prove it they had Memtest86+ running in the background. Intel isn't letting anyone show performance numbers or clock speeds, so Kingston conveniently placed a sign over where that information is normally shown on the monitor.
