8GB Kit (2X4GB) DDR3 1600MHz PC3-12800U 4GB 2Rx8 240-pin Dimm CL11 1.5V Desktop RAM Memory Module

Bottom line: The 8GB Kit (2X4GB) DDR3 1600MHz PC3-12800U 4GB 2Rx8 240-pin Dimm CL11: 8GB kit ships as 2x4GB, filling two DIMM slots for dual-channel on 240-pin boards; main trade-off: DDR3-1600 CL11 is loose timing; CL9 kits of the same speed run tighter.

Pros & Cons

Pros

  • ✓ 8GB kit ships as 2x4GB, filling two DIMM slots for dual-channel on 240-pin boards
  • ✓ Standard PC3-12800 / DDR3-1600 at 1.5V, no low-voltage board mismatch
  • ✓ Unbuffered non-ECC 2Rx8 modules fit consumer Intel and AMD desktop boards

Cons

  • ✗ DDR3-1600 CL11 is loose timing; CL9 kits of the same speed run tighter
  • ✗ Dual-rank 2Rx8 sticks can limit speed on boards with all four slots filled
  • ✗ Non-ECC, so no error correction for workstation or server use
  • ✗ 240-pin desktop DIMM only; will not fit SO-DIMM laptops despite the Macbook mention
