I'm currently running 8 GB of 4 x 2 Gig G.Skill DDR-1066 modules at FSB of 400 and DDR-1000 CAS5. The lowest TRD I can obtain using the Rampage article here on Anandtech is a TRD of 6. TRD of 5 could be used of using CAS 4 or the memory at DDR-1200. My G.Skill sticks don't support either. Are there any 2 GB DDR2 memory modules available anywhere that will run at either CAS 4 DDR-1000 or CAS 5 DDR-1200?
