ThinkMate DDR5 4800 ECC RDIMM Kit

This 64 GB kit contains two 32 GB DDR5 4800 registered DIMMs built for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 1.1 V with CL40 latency. IT teams upgrading these specific platforms gain a validated, plug-in memory solution.

DDR5 4800 registered ECC limits

Registered DIMMs add a clock cycle of buffering, so they only work in server chipsets that support registered memory; consumer desktop boards will not post with them. The DDR5 4800 JEDEC speed caps at PC5-38400 bandwidth, and the kit cannot run faster without platform support for higher data rates. ECC corrects single-bit errors but does not replace system-level redundancy.

No heat spreader, 288-pin RDIMM form factor

The bare green PCB fits standard 288-pin DDR5 RDIMM slots without extra height, easing installation in dense ThinkMate tower chassis. Samsung, Micron or Hynix DRAM chips are used depending on supply, all stress-tested under load. Buyers needing RGB lighting, heatsinks or non-ECC unbuffered modules should look elsewhere.

Questions about this item

Should I pick the 64GB kit or buy single 32GB modules?

The 64GB kit contains two matched 32GB modules (2Rx8) tested together for dual-channel stability in ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 towers.

What does the 4800MHz rating deliver in a live server?

The DDR5 4800 (PC5-38400) modules run at 1.1V with CL40 latency, providing registered ECC bandwidth for multi-threaded workloads on supported ThinkMate platforms.

Is the 288-pin DDR5 RDIMM interface compatible with standard DDR5 slots?

Yes, the 288-pin registered ECC RDIMM fits DDR5 RDIMM slots on ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 servers; it is not compatible with UDIMM or SO-DIMM sockets.
