Crucial 4GB (2GBx2) DDR3 PC3-10600 Memory (CT2KIT25664BA1339) Review
 

The Crucial CT2KIT25664BA1339 gives users 4GB of memory at
DDR3-1333 CAS 9 speeds. You would think there's no room for improvement
but Crucial still puts quality first. This kit easily overclocks to
DDR3 1496 speeds without any voltage or timing adjustments. For less
than seventy bucks, that's hard to beat.
