Description

Core Identifiers & System Classification
  • Brand: CORSAIR
  • Series: VENGEANCE RGB DDR5
  • Model / MPN: CMH32GX5M2X6400C38
  • Memory Type: DDR5 SDRAM (Unbuffered, Non-ECC)
  • Form Factor: 288-Pin U-DIMM (Desktop)

Performance & Capacity Specs
  • Capacity: 32 GB Kit (2 × 16GB dual-channel matched modules)
  • Tested Speed: 6400 MT/s (PC5-51200 — 51.2 GB/s theoretical per module)
  • Tested Latency / Timings: CL38 (38-40-40-84)
  • First Word Latency: 11.87 ns (Slightly quicker than the 6000 CL36 sibling's 12.0 ns, alongside the higher bandwidth)
  • SPD Default Speed: 4800 MT/s (Failsafe boot speed before enabling XMP)
  • SPD Default Latency: CL40 (40-40-40-77)
  • IC / Chip Architecture: Single-Rank (1Rx8), typically SK Hynix ICs on ver 5.43.13 revisions (Single-rank is easier on the CPU memory controller than dual-rank, which is part of why this bin reaches 6400 at a modest 1.35V. Note that Corsair does not guarantee a specific IC vendor — it varies by production batch)
  • Error Correction: On-Die ECC (ODECC) (Chip-level error mitigation, not full system-level ECC)

Electrical & Thermal Management
  • Tested Profile Voltage: 1.35 V (Notably restrained for a 6400 bin — the tighter CL32 variant needs 1.40V)
  • SPD Default Voltage: 1.1 V
  • Power Management: Onboard Overclocking PMIC with dedicated thermal pad
  • Heat Spreader: Solid Anodized Aluminum in Matte Black
  • Module Height: ~44 mm — <span style="color:orange">Verify clearance with large dual-tower air coolers</span>

Lighting & Overclocking Features
  • RGB Lighting: Dynamic Ten-Zone Individually Addressable RGB Light Bar (10 ultra-bright LEDs per module)
  • Software Control: CORSAIR iCUE
    • Custom XMP profile saving
    • Real-time temperature and voltage monitoring (Especially useful at 6400, where you'll want to confirm PMIC thermals during stress testing)
    • Lighting sync across the Corsair ecosystem
  • Performance Profiles: Intel® XMP 3.0 (No EXPO certification on this SKU)

Platform & System Compatibility
  • Optimized Compatibility: Intel® 700 Series and 800 Series DDR5 chipsets — 13th / 14th Gen Core™ and Core™ Ultra
    • (Note: unlike the 6000 CL36 kits, 600 Series / 12th Gen is not in Corsair's optimized list for this faster bin — Z690 boards may need a BIOS update or may not validate 6400 reliably)
  • AMD AM5: Silicon-dependent — read before buying for Ryzen
    • Works via manual profile entry or XMP-read on most AM5 boards
    • Running 6400 MT/s in 1:1 UCLK:MCLK mode is not guaranteed on Ryzen 7000/9000 — it depends on your specific CPU's memory controller quality
