Two blue DDR3 desktop memory modules with aluminum heat spreaders

Corsair

Corsair Vengeance CMZ8GX3M2A1600C9B 8GB (2x4GB) DDR3 1600 desktop RAM

SKU CH-JWS4-4MA1J MPN CMZ8GX3M2A1600C9B

Dual-channel 8 GB DDR3 kit running at 1600 MHz with CL9 latency and blue heat spreaders

  • Total capacity8 GB (2 × 4 GB)
  • Rated speedDDR3 1600 (PC3 12800)
  • CAS latencyCL9
  • Memory timings9-9-9-24
  • Rated voltage1.5 V

Capacity 8GB (2 x 4GB)

  • Dual-channel kit boosts throughput with matched 4 GB modules
  • CL9 latency at 1600 MHz keeps response times low
  • Blue aluminium heat spreader cools chips and matches build theme
  • 50 V operation cuts power draw and raises compatibility
  • Intel XMP support lets the BIOS load rated speed automatically

Dual-channel kit for AMD and Intel platforms

This 8GB kit ships as two matched 4GB modules built for dual-channel operation on AMD systems and Intel dual-processor platforms. The low 1.50V operating voltage keeps power draw modest and compatibility broad across current and upcoming second-generation Intel Core platforms.

DDR3 1600 standard limits peak bandwidth

Running at 1600MHz with a PC3-12800 data rate, the modules deliver the throughput defined by the DDR3 1600 specification. CL9 9-9-9-24 timings set the latency floor, so the kit cannot exceed the bandwidth or response ceiling of the DDR3 1600 standard.

CL9 latency at 1.50V decides fit

The 9-9-9-24 timing at 1.50V is the single figure that determines whether this kit matches a board’s supported profile. If the platform requires a different CAS latency or voltage, the memory will not run at its rated 1600MHz speed.

Questions about this item

Should I pick the 8 GB dual-channel kit or look for a single 8 GB module?

This product is sold as a matched 8 GB kit containing two 4 GB modules; running them together enables dual-channel bandwidth on a compatible motherboard.

What does the 1600 MHz rating deliver once the RAM is installed?

At 1600 MHz with 9-9-9-24 timings and 1.5 V the modules provide a peak transfer rate of PC3 12800, giving responsive performance for everyday desktop workloads.

How does the 240-pin DDR3 interface limit real-world speed?

The 240-pin DDR3 form factor locks the memory to DDR3 signalling; the kit runs at its rated 1600 MHz and cannot operate at speeds or generations that require a different pin layout.
