- DDR5
- Kit capacity
- 48 GB
- Module layout
- 2 × 24 GB
- Tested data rate

First-word latency uses published CAS latency and data rate. It is a simple timing calculation and not an application benchmark. Read the calculation methodology.
Before buying
Compatibility checklist
A matching specification is not a compatibility guarantee. Confirm these points in the motherboard or device documentation.
Confirm the memory generation
The platform must explicitly support DDR5. Different DDR generations are not interchangeable.
Confirm the form factor
The slot must accept CUDIMM. Desktop and compact memory formats can use different physical connections.
Check module height and CPU cooler clearance
Module height is not published for this record. Confirm the exact part dimensions against CPU cooler and case clearance before buying.
Check capacity and module count
Confirm support for 48 GB across 2 modules and check the recommended slot arrangement.
Check speed and profile support
A tested 8,800 MT/s rate may require a supported profile, processor memory controller and motherboard firmware.
On-die ECC does not mean system-level ECC support. It corrects internal DRAM cell errors and does not by itself provide the platform-visible protection associated with ECC memory systems.
