Capacity & purpose

This kit delivers 512GB across eight 64GB DDR5 4800 ECC RDIMM modules. It is built for ThinkMate GPU-optimised servers that require registered memory with error correction.

Installation & pitfalls

Modules seat in standard 288-pin DDR5 slots at 1.10V. The registered design adds electrical buffering, so the server BIOS must support RDIMM operation. Mixing with unbuffered DIMMs or populating slots in the wrong order will prevent boot.

Deciding spec

The 2Rx4 rank organisation and CL40 latency at PC5-38400 define whether the memory controller can train at full speed. Verify the platform qualified vendor list for this exact rank and timing before purchase.

Questions about this item

How can I verify the kit is running at 4800 MT/s with CL40 after installation?

Enter the system BIOS or UEFI and confirm the memory frequency shows 4800 MT/s and CAS latency reads CL40; the registered ECC modules will also report correctable error counts if the platform supports it.

What ships in the box and is anything else required for the ThinkMate GPU servers?

The package contains eight 64 GB DDR5 4800 CL40 2Rx4 1.1 V 288-pin ECC RDIMM modules for a total of 512 GB; no extra cables, brackets or cooling parts are needed for the compatible ThinkMate GPU-optimised servers.

Which capacity and rank option matches the GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX models?

This kit provides 512 GB as eight 64 GB 2Rx4 registered DIMMs, the exact configuration validated for the listed ThinkMate GPU server platforms.
