512GB (8x 64GB) Kingston DDR5 4800MHz ECC RDIMM Memory Unused / Open Box • Brand New Server Pulls • Micron D-Die (MD) ✓ Unused Condition: Brand New Server Pulls
The memory is in unused / open box condition; pulled from brand new servers that I am downgrading to lower-capacity modules.
- ✅ Full Lifespan Ahead: These are not pulled from used, decommissioned servers. They are pulled from brand new in-warranty servers by myself and placed directly into brand new anti-static packaging. These modules still have their full rated lifetime ahead!
⚡ Micron D-Die DRAM Chips (MD Designation)
The exact part number for these Kingston Server Premier modules is KSM48R40BD4-64MD. The "MD" designation signifies that the module assembly is based on Micron (D-DIE) components. This ensures top-tier enterprise reliability, thermal performance, and strict JEDEC standard compatibility with modern AMD EPYC and Intel Xeon Scalable architectures.
🛡️ Satisfaction Guarantee & Warranty Notice
Satisfaction is 100% guaranteed through . You are fully protected and guaranteed to receive perfectly functioning, pristine memory.
Please note: We cannot guarantee that the lifetime warranty will be honored by Kingston, as they explicitly state their warranty is not transferable to secondary market buyers.
Compatibility Warning: These are Registered ECC Memory Modules (RDIMMs). They are strictly designed for enterprise servers and workstations. They will absolutely not work in standard consumer desktop motherboards that only accept unbuffered memory.
⚙️ Detailed Engineering Specifications
Each module is an 8G x 80-bit (64GB) DDR5-4800 CL40 SDRAM (Synchronous DRAM), 2Rx4, ECC memory module, based on forty 4G x 4-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR5-4800 timing of 40-39-39 at 1.1V. Each 288-pin DIMM utilizes standard gold contact fingers.
