Compatibility notes

This memory is intended for advanced platforms and high-capacity, multi-DIMM configurations. Compatibility is highly motherboard and CPU specific.

Before purchasing, you must verify this exact module against your motherboard’s QVL (Qualified Vendor List).

When checking the QVL, confirm all of the following match exactly:

• Full memory model number
• Per-DIMM capacity (for example 32GB, 48GB, 64GB)
• Total DIMM count (for example 4 DIMMs vs 8 DIMMs)
• Rated speed and primary timings
• CPU generation used for validation
• Validation method (single DIMM validation vs matched kits)
  
  

Some motherboards validate single DIMMs only, not full multi-DIMM kits. Mixing DIMMs or assuming kit-level support can result in reduced speeds or instability.

Returns are not accepted for compatibility, stability, or speed issues if this memory is not explicitly listed on the motherboard QVL for the intended configuration.
