Corsair TWIN2X1024-5400C4PRO
 

Corsair has earned a reputation as makers of fast and reliable ram, and
this tradition continues from past ram formats and into DDR-2. While not
earth shattering, performance-wise today, DDR-2 is forward thinking as
Intel scales their clock speeds, and the TWIN2X Pro Series is up to the
task.
