  • DDR5 4800 speed moves data quickly for modern CPUs
  • CL40 CAS latency keeps response times tight
  • 10 V operation reduces power draw and heat

64 GB Dual-Channel DDR5 Kit

This Corsair Vengeance kit delivers 64 GB of desktop memory across two 32 GB modules. It uses the DDR5 standard and runs at 4800 MT/s with a CL40 latency. The kit targets Intel 600 series platforms and users who need high capacity for demanding workloads.

DDR5 4800 JEDEC Baseline

The modules operate at the base DDR5 4800 (PC5 38400) data rate without requiring manual tuning. Rated timings are 40-40-40-77 at 1.10 V. Intel XMP 3.0 profiles are available for higher speeds on compatible motherboards, but the guaranteed out-of-box specification remains 4800 MT/s CL40.

288-Pin DIMM Form Factor

Each stick uses the standard 288-pin DIMM layout and includes a black aluminium heat spreader. The dual-channel kit is designed for motherboards with four DDR5 slots. Verify that your board supports 32 GB per DIMM and the 1.10 V operating voltage before purchase.

Questions about this item

Should I choose this 64GB (2×32GB) kit or a single 32GB module?

The kit provides 64GB in a matched pair tested for dual-channel operation. A single module would run in single-channel mode and halve total capacity.

What does DDR5 4800 (PC5 38400) deliver in daily use?

The modules run at 4800MT/s with CL40 timings at 1.10V, giving high bandwidth for multi-core workloads and gaming when XMP 3.0 is enabled.

How does the 288-pin DDR5 interface affect maximum speed?

The 288-pin DDR5 slot caps this kit at its rated 4800MT/s; faster speeds would require modules rated for higher data rates.
