Next on the list of ingrediets for my new computer (based on an Asus P6T Deluxe V2 Motherboard and an Intel Core i7 920 CPU), is the memory.  The new range of Core i7 processors require DDR3 Memory (currently available in 2GB modules) and the P6T has six available slots, so I ordered 12GB (2kits of 3x2GB) of Kingston KVR1333D3N9K3/6G

Once installed, I added some extra 'refreshment' (dedicated DRAM cooling fans) and tweaked the bios settings on the M/B to increase the cards speed from 1333Mhz to 1501Mhz.  This a fairly conservative setting for this system but I am more interested in stability... with just a touch of extra speed.

So far, these modules have worked very well, although I have not managed to use all 12Gig yet.  The most I have used has been around 10GB while running multiple virtual machines (debian, W2K, XP, Vista & 7-RC) on top of Linx Mint

When compared to previous versions (DDR & DDR2), DDR3 modules really kick it up a notch.... helping to make the overal system fast and stable.

While I could easily spend more $$$ on faster, higher-end DRAM modules, I don't see the need.  This thing is plenty fast enough for most of the stuff I do.....  even when running up to 6 OS's at once!
