Refurbished DDR5 Memory Chips
DDR5 SDRAM is the current mainstream DRAM generation for new servers and computers. Supply of new parts is prioritised for large customers. AURCAL sources DDR5 chips to order and confirms what can be supplied and tested before it quotes.
- We source DDR5 to order and state the condition on every quote.
- Parts are inspected, reballed where needed, tested and burned in at our Shenzhen base.
- The list below is reference data from public part lists, not our inventory.
How is DDR5 different from DDR4?
DDR5 runs from a lower supply voltage than DDR4 (1.1 V versus 1.2 V) and starts at higher data rates (4800 Mbps and above). It also adds on-die ECC. The two generations are not interchangeable.
What should I match when sourcing DDR5?
Match the full part number and suffix, the density and width, the speed grade and the package. Check the manufacturer datasheet for each.
Key differences
| Generation | Supply voltage | Typical data rates |
|---|---|---|
| DDR4 | 1.2 V | 1600 to 3200 Mbps |
| DDR5 | 1.1 V | 4800 Mbps and above |

Frequently asked questions
Is test coverage the same for every device type?
No. The test scope depends on the device type and is confirmed per part number in your quote.
How do I request this?
Use the quote form with the exact part number and quantity. We source to order and confirm availability before we quote.
