A-Data DDR2 PC8000 Xtreme-Edition - 1GB kit
 

I was able to get these modules up above 1100MHz with 5-5-5-15 timings and 2.4V, but not much further. Still this is an excellent result for modules only rated at 1000MHz, and would give you some more breathing space if you are overclocking a low multiplier CPU like the Core Duo E6300’s
