Kingston has put together a 16GB, 4DIMM quad (or dual) channel DDR-2400 kit with timings of 11-13-13-30 available for $160.  They've designed compact heat spreaders for this kit so even with the tight confines of the CPU socket which have become common today you should be able to fit these in your system without much difficulty.  From TechPowerUp's testing these DIMMs seem to be running all out at stock speeds, even upping the voltage only allowed them a stable 2468MHz perhaps not a problem on boards which cannot break 2400MHz in the BIOS.  They do mention that the Anniversary Special Editions have limited availability so if their review tempts you, purchase this kit as soon as you can.

"To commemorate the 10th anniversary of the HyperX brand, Kinston has released a limited edition line up called the HyperX Genesis 10th Anniversary Special Edition. We take a look at the top-end 16 GB 2400 MHz CL11 kit, a blazing fast kit with performance to match."
