32GB dual-channel DDR5 kit for modern desktops

This Corsair Vengeance kit provides 32GB of DDR5 memory in a matched pair of 16GB modules. It targets builders and upgraders running Intel 600-series or AMD platforms that support DDR5. The black heat spreader keeps thermals in check during sustained workloads.

DDR5 4800 CL40 at 1.10V with XMP 3.0 and AMD EXPO

The modules run at 4800 MT/s (PC5 38400) with timings of 40-40-40-77 at the standard 1.10V. Both Intel XMP 3.0 and AMD EXPO profiles are programmed on the SPD, so the rated speed activates with a single BIOS toggle on compatible boards.

Standard 288-pin installation.

Installation follows the usual 288-pin DIMM procedure — align the notch, press until the retention clips click, and populate the correct slots for dual-channel operation. The most common issue is leaving the memory at JEDEC defaults; remember to select the XMP 3.0 or EXPO profile in firmware to reach 4800 MT/s.

Questions about this item

What does the 4800 MT/s speed mean once the kit is installed in a real machine?

The modules run at the JEDEC DDR5 4800 baseline, delivering 4800 MT/s per module without any manual tuning.

What interface standard does this kit use and what does it cap in practice?

It uses the 288-pin DDR5 interface with Intel XMP 3.0 and AMD EXPO profiles, so the motherboard firmware controls the final speed ceiling.

What physical clearance does the low-profile heat spreader need to fit?

The compact form-factor keeps height low for wide compatibility with most CPU coolers and small-form-factor cases.
