Testing of high-end Intel motherboards requires secondary components of a high-end spec too. It stands to reason that we'd want the fastest RAM possible to really try to push the boards. James has sent me a pic of the RAM we're going to be using the HEXUS.labs...
It's PC8000, or DDR2-1000, which means it's flippin' fast. It's Crucial's Ballistix PC8000, and yes, there's two kits in there, giving a lovely 2GiB.
Now, a virtual cookie to whoever can guess the model of the motherboard in which the RAM is sat in that picture.
