Depending on the type of memory that the VIA Isaiah will be able to use, the Super Talent Project X 2x1GB PC3-14400 may be a great match.  It runs at 1800MHz, with 7-7-7-21 timings and draws only 2v, fairly low for the speed offered, and uses large passive heatsinks to keep it cool.  Of course, you can’t expect Overclockers Online to leave these DIMMs at stock speeds, 920MHz was the top speed they hit at default timings, but they also relaxed the timings and topped the board out, while using less than the full 2v.

“Despite the slightly less than stellar performance at the rated timings and voltage, this sample of the Super Talent Project X memory excelled both at tighter and looser timing sets with slight bumps in voltage. It easily maxed out the Asus P5K3-Deluxes ability to run memory stable at DDR3-1900 with 8-7-6 timings and did so with a more than acceptable 2.01v as measured by a digital multi-meter. Combined with the exciting 6-6-5 clocking ability, these Project X modules still managed to impress with very reasonable voltages”
